Description:
CROSS-REFERENCE TO RELATED APPLICATIONS  
      The present application is a Divisional Application of U.S. application Ser. No. 09/659,771, filed Sep. 11, 2000, which is based upon and claims the benefit of priority from the prior Japanese Patent Applications No. 11-266688, filed Sep. 21, 1999; and No. 2000-255632, filed Aug. 25, 2000, the entire contents of which are incorporated herein by reference. 
    
    
     BACKGROUND OF THE INVENTION  
      The present invention relates to a medical apparatus lease system and a medical apparatus compatible with this medical apparatus lease system.  
      Jpn. Pat. Appln. KOKAI Publications No. 5-49647 and 8-164145 disclose information on the life cycle of a medical apparatus and on the needs for maintenance as well as a technique for monitoring the functional status of the medical apparatus.  
      There are many medical apparatus lease companies that lease medical apparatuses to medical facilities; lease fees are paid depending on how many times the medical apparatus has been used or on the amount of time for which the medical apparatus has been leased.  
      On the other hand, a method of maintenance for an apparatus has been proposed. For example, Jpn. Pat. Appln. KOKAI Publication No. 10-177325 discloses a management system for storing information on errors that have occurred in a product. Jpn. Pat. Appln. KOKAI Publication No. 10-222568 also discloses a system for managing a product by storing individual information on the product and the history of repairs.  
      Jpn. Pat. Appln. KOKAI Publications No. 5-49647 and 8-164145, however, requires a medical apparatus user or a maintenance staff member to directly read monitored information from the medical apparatus if a functional or operational error has occurred in the medical apparatus. Thus, whenever the medical apparatus is found to have a safety problem, a medical apparatus user such as a doctor or a nurse who has noticed the problem, or a maintenance staff member in the hospital must communicate with the medical apparatus manufacturer or distributor. This requires a large amount of time and labor.  
      In addition, if the medical apparatus becomes defective and can no longer used, the medical apparatus lease company is asked for a monetary compensation such as a reduction in the lease fees. This is disadvantageous to the operation of the lease business.  
      A medical apparatus lease company that leases a medical apparatus to a medical facility and charges lease fees depending on the number of times that the medical apparatus has been used or the amount of time for which the equipment has been used must visit the medical facility using the equipment to check the number of previous operations. Disadvantageously, these visits require a large amount of time and a high labor cost.  
      Furthermore, the apparatus described in Jpn. Pat. Appln. KOKAI Publication No. 10-177325 stores only set values or a usage status when an error occurs in the product but not information such as the number of times that the equipment has been operated before the error occurred. In addition, although Jpn. Pat. Appln. KOKAI Publication No. 10-222568 stores the history of repairs, no action can be taken for a possible failure depending on the length of time that has passed since the last repair or the number of times that the equipment has been operated since the last repair. Neither of these applications shows how many times a treatment instrument has been used, so that it may be difficult to definitely determine when to replace the instrument, resulting in a trouble. It is uneconomical to replace, for safety, the medical apparatus long before its life is over. Therefore, none of the conventional medical apparatus is compatible with the medical apparatus lease system.  
     BRIEF SUMMARY OF THE INVENTION  
      It is a first object of the present invention to provide a medical apparatus lease system that enables a medical apparatus lease company to analyze and understand the usage status of a medical apparatus or a problem therewith and to determine lease fees depending on how and how many times the medical apparatus has been used.  
      It is a second object of the present invention to provide a medical apparatus compatible with a medical apparatus system which can reduce possible troubles by storing the number of times that a treatment instrument has been used in order to allow a user to determine when a specified number of usage has been reached and to check the number of previous usage to replace the treatment instrument with a new product as required.

     DETAILED DESCRIPTION OF THE INVENTION  
     First Embodiment  
      (Configuration)  
       FIG. 1  shows a conceptual drawing of the entire configuration of a medical apparatus lease system according to a first embodiment of the present invention.  FIGS. 2 and 3  show a flow chart of the entire medical apparatus lease system according to the first embodiment.  FIGS. 4 and 5  show a flow chart of a medical apparatus according to the first embodiment.  FIG. 6  shows types of fee systems for the medical apparatus lease system according to the first embodiment.  FIGS. 7 and 8  show examples of screen displays on a terminal at a hospital according to the first embodiment.  FIGS. 9 and 10  show examples of screen displays on a terminal of a medical apparatus supplier according to the first embodiment.  FIGS. 11A and 11B  show examples of client, equipment, lease condition input screen displays.  
      First, the entire configuration of a medical apparatus lease system according to a first embodiment will be explained with reference to  FIG. 1 .  
      A medical apparatus A 1 , a medical apparatus A 2 , and a plurality of medical apparatus (not shown) which are installed in a hospital A and operated by the present system are connected to a terminal A via a communication network within the hospital. Likewise, a plurality of medical apparatuses used in a hospital B or a plurality of other hospitals and operated by the present system are each connected to a terminal at the hospital via a network within the hospital. Then, the terminal A at the hospital A and the terminals at the other hospitals can be connected to a server  201  operated by a medical apparatus supplier via a communication network, for example, a network such as the Internet  200 . Furthermore, the communication network, for example, a network such as the Internet  200  has a server  202  communicably connected thereto and operated by a medical apparatus maintenance company, a sales staff member (not shown), or the like.  
      With this configuration, electronic information sent from the medical equipment used in each hospital can be transmitted to the corresponding terminal device via the corresponding in-hospital communication network, so that the electronic information sent to the terminal device from the medical apparatus can be communicated to the server  201  operated by the medical apparatus supplier via the communication network, for example, a network such as the Internet  200 . In contrary, electronic information sent from the server  201  operated by the medical apparatus supplier can be communicated to the terminal device at the hospital via the communication network, for example, a network such as the Internet  200 , or electronic information can be communicated from the terminal device at each hospital to each medical apparatus via the in-hospital communication network.  
      Similarly, the server  202  can communicate electronic information from the medical apparatus maintenance company or the sales staff member (not shown) to each hospital or the medical apparatus supplier via the communication network, for example, a network such as the Internet  200 .  
      (Operation)  
      The relationship between flows for the medical apparatus, the hospital terminal, and the medical apparatus supplier will be described with reference to the flow chart in  FIGS. 2 and 3 .  
      First, the flow for the server  201  at the medical apparatus supplier will be explained.  
      At Stp S 1  (Stp represents a step) and Stp S 2 , the server  201  is powered on to start up the system. At Stp S 3 , conditions for a lease contract are input. The contents of the input include information on a client such as a contracted hospital and the name of the doctor, the type of a medical apparatus used, the unit price of and usage conditions for the medical apparatus, and conditions based on the lease contract such as an online payment or an offline payment. Furthermore, a sales staff member, a maintenance company in that district, and other information can be input.  
      For the unit price and usage conditions, fee systems such as those shown in  FIG. 6  are set, including a Type A, a “fee system with which the amount due is determined depending on the number of times that the apparatus has been operated”, a Type B, a “fee system with which the amount due is determined depending on the number of outputs”, a Type C, a “fee system with which the amount due is determined depending on the amount of time for which the apparatus has been operated”, and a Type D, a “fee system with which the amount due is determined depending on the amount of energy used”.  
      Moreover, the Type A allows selection of detailed conditions including a Type A-1, a “method for counting the number of times that a probe has been connected to the apparatus”, a Type A-2, a “method for counting the number of times that a handle has been gripped and the number of times that the apparatus has actually been operated”, and a Type A-3, a “method for counting at least one of the number of connection times and the number of gripping times”. The Type B allows selection of detailed conditions including a Type B-1, a “method for counting the number of times that energy has been output”, a Type B-2, a “method for counting the number of times that a switch such as a foot switch or a hand switch has been depressed”, and a Type B-3, a “method for counting at least one of the number of energy outputs and the number of switch depressions”. The Type C allows selection of detailed conditions including a Type C-1, a “method for noticing output of energy and counting the amount of time for which energy has been output”, a Type C-2, a “method for counting the amount of time for which the switch such as the foot switch or the hand switch has been depressed”, and a Type C-3, a “method for counting at least one of the amount of time for energy outputs and the amount of time for switch depressions”. The Type D allows selection of a detailed condition, that is, a Type D-1, “a method for recording an accumulated value of an output value and an output duration and counting the amount of energy output”. These conditions are input based on a contract with the medical apparatus used.  
      Once all conditions for the lease of the apparatus have been input, the process stand by at Stp S 4  until data on the use of the apparatus is transmitted. When data from the apparatus is received, a data reception status is checked at Stp S 5 . If there is a problem with the data reception, it is communicated to the hospital terminal. If there is no problem with the data reception, the hospital terminal is notified of the correct reception and the server simultaneously processes the received data (Stp S 6 ) to identify the hospital and the apparatus and calculate the number of times that this apparatus has been used (Stp S 7 ). Based on the data calculated at Stp S 7 , the server charges lease fees to a medical facility such as the hospital at the end of a month or a contracted period according to contract conditions (Stp S 8 ).  
      The billing method may be online fee processing, offline money transfer, or the like based on the contract conditions. If any error is found in the apparatus when the received data are processed at Stp S 6 , the corresponding status may be communicated to a medical facility such as the hospital using a data communication network shown in  FIG. 1  or means other than the communication network such as the Internet shown in  FIG. 1 , the network using telephones or electronic mails. It can be communicated to a maintenance service company in the district.  
      Once the billing process has been completed at Stp S 8 , it is determined whether or not to renew the contract with the medical apparatus user (Stp S 9 ). If the contract is not to be renewed, the process returns to Stp S 4  to enter the standby state to wait for information on the use of the apparatus from the hospital. Alternatively, if the contract with the hospital is to be renewed, the process shifts from Stp S 9  to Stp S 3  to renew the contents of the contract. Since the server  201  can carry out a plurality of processes in parallel, data can be received at any point of time within the above flow.  
      Examples of display screens of the server at the medical apparatus supplier will be explained with reference to  FIGS. 9 and 10 .  
      When the system is started up, a main menu screen P 6 - 1  is displayed. When “Retrieve” is selected, the display shifts to a retrieval condition input screen P 6 - 11  to retrieve various information stored in the server. Alternatively, when “Input Usage Conditions” is selected in P 6 - 1 , the display shifts to a usage-condition input screen P 6 - 12 . When an items to be input, “Client Information Input” or “Apparatus Information Input” is selected, the display shifts to an apparatus information input screen P 6 - 13  or a client information input screen P 6 - 14 .  
      The details of the apparatus information input screen P 6 - 13  and the client information input screen P 6 - 14  are shown in  FIGS. 11A and 11B . For the input of the client information, it is possible to input the names of a client hospital and a section, the name of a doctor who principally uses the apparatus, a billed person or organization, that is, the doctor, the section, the hospital, or the group of affiliated hospitals as shown in  FIG. 11A . Billing conditions can be set in accordance with the contract conditions; that is, the fees can be paid at the end of the contracted period or at the end of every month or week. The details of the payment can also be set depending on the form of the hospital, that is, an online or offline payment. For the input of the apparatus information, it is possible to input the apparatus used, a probe or the like which is connected to the apparatus for operation, conditions based on the various fee systems shown in  FIG. 6 , as shown in  FIG. 11B .  
      When “Output Usage Status and Results” is selected in a main menu screen P 6 - 1 , shown in  FIGS. 9 and 10 , the display proceeds to a screen for totaling and displaying data stored in the server at the medical apparatus supplier (P 6 - 3 ), a screen for allowing the usage status of the apparatus to be manually input (P 6 - 6 ), or a screen for showing a reception status (P 6 - 7 ). Alternatively, when “Cost Processing” is selected in the main menu screen P 6 - 1  shown in  FIGS. 9 and 10 , the display shifts to a screen for allowing a past payment status, the current lease fees, or the like to be totaled and calculated (P 6 - 4 ). When “Others” is selected in the main menu screen P 6 - 1  shown in  FIGS. 9 and 10 , the display proceeds to a screen for enabling communications with the hospital (P 6 - 8 ), including a report on the fees for the apparatus, a request for the payment of the fees, and the notification of the needs for the replacement of consumables and for the repair of the apparatus, a screen for notifying the sales staff member of the replacement or repair of consumables, the usage status of the apparatus in the hospital, or the like (P 6 - 10 ), or a screen for notifying the manufacturer of a consumption status of consumables in the market or providing the manufacturer with information for a manufacturing plan for the factory based on the consumption status and information on the operation or quality of the apparatus in the market (P 6 - 9 ).  
      Subsequently, the flow for the hospital terminal will be explained with reference to  FIGS. 2 and 3 .  
      When the hospital terminal is started up at Stp H 1  and Stp H 2 , it is determined that data transmitted from the medical apparatus described later has already been processed (Stp H 3 ). If the received data have already been processed, the process waits for data from the medical apparatus to be received (Stp H 4 ). If data has been received from the apparatus or it is determined at Stp H 3  that the received data have not been processed yet, the hospital terminal is requested to connect to a network, for example, the Internet via which the terminal is connected to the server  201  at the medical apparatus supplier (Stp H 5 ). If the connection to the network is not completed (Stp H 6 ), the hospital terminal is requested again to connect to the network (Stp H 5 ). Once the connection to the network has been completed, the hospital terminal is requested to transmit data from the medical apparatus to the server  201  at the medical supplier  201  (Stp H 7 ), and the data are transmitted (Stp H 8 ).  
      If the server  201  at the medical apparatus supplier was unable to receive data accurately, the cause of the transmission failure and possible action to take are transmitted to the hospital terminal in addition to the message indicating the failure (Stp H 9 ). If the hospital terminal attempts to retransmit the data, the process returns to Stp H 7 . If, however, the hospital terminal does not attempt to retransmit the data, it can store the data (Stp H 11 ) and end the system (Stp H 14  and Stp H 15 ).  
      If the transmission to the server  201  at the medical apparatus supplier has been completed, a message is displayed indicating that the transmission has been completed (Stp H 12 ) and the hospital terminal can clear the connection with the network (Stp h 13 ) to end the system (Stp H 14  and Stp H 15 ). Since the terminal can carry out a plurality of processes in parallel, data can be received at any point of time within the above flow.  
      Examples of display screens of the hospital terminal will be explained with reference to  FIGS. 7 and 8 .  
      When the terminal is started up and if any data remains to be transmitted (Stp  5 - 1 ), the display shifts to a data transmission screen (P 5 - 6 ) to transmit the data. If all the data have been transmitted (Stp  5 - 1 ), the display shifts to the main menu screen (P 5 - 1 ) to further transfer to “Transmit Data”, “Retrieve”, “Display/Input Usage Conditions”, “Output Usage Status and Results”, “Cost Processing Status”, or “Others”.  
      When “Transmit Data”, is selected in the main menu screen (P 5 - 1 ), the display shifts to a data transmission screen to allow a data transmission operation to be performed. When “Retrieval” is selected in the main menu screen (P 5 - 1 ), the display shifts to a display/input usage conditions screen (P 5 - 8 ) to allow “Display/Input Client Information” or “Display/Input Apparatus Information” to be selected. When “Display/Input Client Information” is selected, the current client information is displayed (P 5 - 9 ), and when “Display/Input Apparatus Information” is selected, the current apparatus information is displayed (P 5 - 10 ). To change already input information, the display shifts to a “Change Registered Screen” screen (P 5 - 11 ), but to preclude an outsider from rewriting the data, an ID and a password are input in an “Input and Check ID Information” screen (P 5 - 12 ) so that if the ID and password are correct (Stp  5 - 2 ), the display can shift to an “Input Client Information” screen (P 5 - 14 ) or an “Input Apparatus Information” screen (P 5 - 15 ) to allow the corresponding information to be input or modified. Once the corresponding information has been input or modified, the display shifts to a “Display Client Information” screen (P 5 - 9 ) or a “Display Apparatus Information” screen (P 5 - 10 ) to display the latest input information. If the ID or password is incorrect (Stp  5 - 2 ), a message is displayed indicating that the ID or password is incorrect (P 5 - 15 ) and asking an ID and a password to be input again (P 5 - 12 ). The display cannot shift to the “Input Client Information” screen (P 5 - 14 ) or the “Input Apparatus Information” screen (P 5 - 15 ) as long as the incorrect ID or password is input (Stp  5 - 2 ).  
      When the “Output Usage Status and Results” is selected in the main menu screen (P 5 - 1 ), the display shifts to a screen for retrieving and outputting the usage status of the medical apparatus (P 5 - 3 ). When “Cost Processing Status” is selected in the main menu screen (P 5 - 1 ), it can be checked how the lease fees have been paid to the medical apparatus supplier (P 5 - 4 ) even if the fees are paid online. When “Others” is selected in the main menu screen (P 5 - 1 ), “Communicate with Manufacturer” may be selected to ask the manufacturer for a repair or an inspection, or “Communicate with Sales Staff” may be selected to order consumables, or “Display Information on Medical Apparatus” may be selected to communicate a message “Consumables Ordered” to a doctor or nurse who actually use the medical apparatus.  
      Subsequently, the flow for the medical apparatus at the hospital will be explained.  
      When the medical apparatus is started up (Stp E 1  and Stp E 2 ), it is checked whether or not the medical apparatus transmitted data when previously operated (Stp E 3 ). If the data transmission has been completed, the medical apparatus is operated (Stp E 4 ) and results of the operation are totaled (Stp E 5 ). If it is determined at Stp E 3  that the data transmission has not been completed, when all the results of the operation have been totaled at Stp E 5 , the medical apparatus is requested to connect to the hospital terminal (Stp E 6 ) and then transmits data on its own operation to the hospital terminal (Stp E 7 ). If an error has occurred during the data transmission, a message is displayed indicating that the transmission has failed as well as the cause of the failure and action to take (Stp E 8 ). When the medical apparatus attempts to retransmit the data (Stp E 9 ), the process returns to Stp E 6 , where the medical apparatus connects to the hospital terminal before retransmitting the data. Alternatively, if the medical apparatus does not attempt to retransmit the data, the process proceeds to Stp E 10 , where data on the operations of the medical apparatus are stored and the operation of the medical apparatus is ended (Stp E 13  and Stp E 14 ).  
      Alternatively, if the data has been smoothly transmitted to the hospital terminal, a message is displayed indicating that the transmission has been completed (Stp E 11 ). To repeat operating the medical apparatus (Stp E 12 ), the process returns to Stp E 4  to operate the medical apparatus again. If the operation of the medical apparatus is not to be repeated, the process proceeds to Stp E 13  and Stp E 14  to complete the use of the medical apparatus.  
       FIGS. 4 and 5  show the flow for the medical apparatus at the hospital in further detail in terms of detection of a probe used in combination with the medical apparatus. When the medical apparatus is started up at Stp 1  and Stp 2 , it is checked whether or not all the data have been transmitted (Stp 3 ). If any data remains to be transmitted, it is checked whether the medical apparatus is connected to the network (Stp 14 ). If the apparatus is not connected to the network, it connects to the network (Stp 15 ) to transmit the data (Stp 16 ). If the data have been reliably transmitted (Stp 17 ), a message is displayed indicating that the transmission has been completed (Stp 18 ) and the process shifts to a step at which the medical apparatus is operated.  
      Alternatively, if an error has occurred during the data transmission (Stp 17 ), message is displayed indicating that the transmission has failed as well as the cause of the failure and action to take (Stp 19 ). When the medical apparatus attempts to retransmit the data (Stp 20 ), action is taken against the transmission error (Stp 22 ) before shifting to a data transmission (Stp 16 ). Alternatively, if the medical apparatus does not attempt to retransmit the data, the data are stored (Stp 21 ) and the process shifts to a step at which the medical apparatus is operated.  
      If the medical apparatus is not to be operated (Stp 4 ), data on the last usage conditions are stored (Stp 25 ) to complete the use of the medical apparatus (Stp 26  and Stp 27 ). If the medical apparatus is to be operated (Stp 4 ), a probe or the like which is used in combination with the medical apparatus is connected thereto (Stp 5 ). The probe, as used herein, refers to a general medical device connected to an enclosure section, for example, a probe for an electric scalpel, an ultrasonic coagulation incision probe for an ultrasonic coagulation incision device, or an endoscope for an endoscope drive device is used.  
      When the probe to be used is connected at Stp 5 , detection of the connected probe is recognized (Stp 6 ). Data for recognition of detection of the probe (St 6 ) are used to, for example, select a lease fee system that varies depending on the probe used as shown in  FIG. 6  or to make determinations if the probe has a characteristic, for example, durability that varies depending on the probe used. After the recognition of the probe (St 6 ) has been completed, the operation and functioning of the probe are detected (St 7 ). The detection of the operation and functioning of the probe means that the probe is operated to actually output data to check the operation of the apparatus in order to ascertain whether the probe functions correctly. This is implemented using an operation checking circuit provided in the apparatus; the operation of the probe is also visually inspected.  
      Additionally, when the client selects a fee system beforehand, a setting is input which corresponds to the condition that, for example, “up to three energy outputs required to detect the operation and functioning are not converted into fees”, so that the medical apparatus user can carry out operation checks without increasing the fees if the user executes a specified or smaller number of operation checks for a specified or shorter amount of time using a specified or smaller amount of energy. After the probe has been checked for operation and functioning at Stp 7 , it is determined whether the apparatus operates correctly (STp 8 ). If there is a problem with the operation of the apparatus, for example, the apparatus cannot be used, the probe cannot be commanded, the apparatus or the probe must be repaired, or another action must be taken, a message is displayed at Stp 23  indicating that the apparatus operates incorrectly as well as action to take. Then, required action is taken (Stp 24 ) and the user is requested to determine whether to operate apparatus again (Stp 4 ). If there is a problem with the operation of the apparatus, Stp 4 , Stp 5 , Stp 6 , Stp 7 , Stp 8 , Stp 23 , and Stp 24  are repeated so that the medical apparatus cannot be used until the problem with the operation of the apparatus has been solved. If the apparatus operates correctly, the process shifts from Stp 8  to Stp 9  where the status is displayed. At Stp 9 , the display shows how the medical apparatus has recognized the probe, for example, the type of the connected probe, the number of times that the probe has been used, the number of times that the probe can be used before its life expectancy, so that the contents of automatic determinations made by the medical apparatus can be checked against the recognition of the medical apparatus user. Once the medical apparatus user has determined to operate the medical apparatus, the process shifts to the operation of the apparatus (Stp 10 ). The data on the usage status of the apparatus are stored in the medical apparatus each time it has been operated (Stp 11 ). If the apparatus is continuously used (Stp 12 ), Stp 10  and Stp 11  are carried out to monitor how the medical apparatus is operated, so that data on the usage status is stored (Stp 11 ).  
      Further, when the probe has finished its life expectancy and is replaced with another (Stp 13 ), once the new probe has been connected (Stp 5 ), the process is repeated starting with the recognition of the newly connected probe (Spt 6 ). Alternatively, when the operation is ended without using the new probe (Stp 13 ), the process shifts to the check on the connection to the network (Stp 14 ) and then passes through Stp 14 , Stp 15 , Stp 16 , Stp 17 , Stp 18 , Stp 19 , Stp 20 , Stp 21 , and Stp 22 . After a data transmission, Stp 4 , Stp 25 , Stp 26 , and Stp 27  are carried out to complete the use of the medical apparatus.  
      As described above, by following the flows for the medical equipment at the hospital, the terminal at the hospital, and the sever  201  at the medical apparatus supplier, the data on the operation of the medical apparatus can be communicated between the medical equipment at the hospital and the terminal at the hospital and the sever  201  at the medical apparatus supplier.  
      With the above described configuration, the medical apparatus lease company can easily and appropriately analyze and understand the usage status of the medical apparatus and problems therewith and can add up the lease fees depending on the number of times that the medical apparatus has been used or on the usage status of the medical apparatus.  
      The above effects will be described in further detail. The above described embodiment solves the problem with the prior art that a large amount of labor and time is required when the sales staff member visits the hospital to check the medical apparatus for the usage status to calculate the lease fees. Another unique effect of this embodiment is that the manhour and labor cost of the sales staff member can be reduced to provide a more inexpensive and efficient medical apparatus lease system, thereby reducing medical costs.  
      Further, although the sales or maintenance staff member conventionally visits the hospital to check the medical apparatus for operation, the medical apparatus lease system according to this embodiment enables the medical apparatus to be checked for operation without requiring the sales or maintenance staff member to visit the hospital. Consequently, as described above, the manhour and labor cost of the sales staff member can be reduced to provide a more inexpensive and efficient medical apparatus lease system, thereby reducing medical costs. Errors are immediately communicated to the medical apparatus supplier or the lease company without the needs for periodical visits of the sales or maintenance staff member to the hospital for checking the medial apparatus for operation as in the prior art. As a result, the medical apparatus can be repaired or replaced earlier.  
      The hospital conventionally orders consumables by constantly checking how they are consumed, but with the medical apparatus lease system, the medical apparatus supplier or the lease company manage the consumables so that they are automatically ordered from their suppliers and then delivered to the hospital by the sales staff member. This eliminates the need to check how the consumables are consumed or to order them, thereby reducing the manhour and labor cost in the hospital to diminish hospital operation costs and medical costs.  
      In addition, the medical apparatus supplier can order products from a maker, a factory, or the like as appropriate while monitoring the usage status of the medical apparatus. This can be reflected in a production and delivery plan of the maker or factory in a short time, thereby facilitating production planning while preventing delayed deliveries and unwanted inventories.  
      Additionally, since the ID and password are used to permit only the authorized people to input the client or apparatus information, outsiders are prevented from conducting unwanted data rewrites or the like to unfairly process data.  
      Moreover, in tentatively operating the medical apparatus to check it for operation and functioning, a program for avoiding increasing the fees enable the doctor or nurse who uses the medical apparatus to test the apparatus without the need to pay unwanted costs.  
      In addition, the lease fee system for the medical apparatus can be selected for each probe or medical apparatus from a program for determining the amount due depending on the number of times that the medical apparatus has been used, a program for determining the amount due depending on the number of previous outputs from the medical apparatus, a program for determining the amount due depending on the amount of time for which the medical apparatus has been used or leased, a program for determining the amount due depending on the amount of energy used by the medical apparatus. Consequently, optimum payment conditions can be selected depending on the scale of the hospital or for each treatment department.  
      Further, the online payment simplifies payment operations, reduces the payment period, and improves the efficiency of fund management.  
      The above described first embodiment provides a medical apparatus lease system with which the medical apparatus lease company can easily and appropriately analyze and understand the usage status of the medical apparatus and problems therewith and can add up the lease fees depending on the number of times that the medical apparatus has been used or on the usage status of the medical apparatus.  
     Second Embodiment  
      Next, a medical apparatus compatible with the above described medical apparatus lease system will be explained as a second embodiment of the present invention. An energy treatment system with an experience-on-usage storage function according to the first embodiment of the present invention will be described below with reference to  FIGS. 12 and 13 .  
      (Configuration)  
       FIG. 12  shows an ultrasonic coagulation and incision treatment instrument  1  for coagulation incision using ultrasonic waves as treatment energy. The ultrasonic coagulation incision treatment instrument  1  has a treatment instrument main body  2  and a vibrator unit  3 . When the ultrasonic coagulation incision treatment instrument  1  is used, the treatment instrument main body  2  and the vibrator unit  3  are connected and assembled together via a connector  4  provided on the treatment instrument main body  2 .  
      The treatment instrument main body  2  comprises a sheath  5  and a hand-held section  6 . The sheath has a treatment section  7  projected from a tip thereof. The hand-held section  6  has a fixed handle  8  and a movable handle  9 . The treatment section  7  is opened or closed by rotationally moving the movable handle  9 .  
      For example, the sheath  5  is inserted into the abdominal cavity through a trocar or an endoscope to allow the treatment section  7  at the tip to grip a biological tissue in the abdominal cavity. Ultrasonic vibration is applied to the treatment section  7  to coagulate and cut the gripped biological tissue.  
      The vibrator unit  3  has a pin  11  which enters a connection  13  of the hand-held section  6  for connection when the treatment instrument main body  2  and the vibrator unit  3  are connected and assembled together.  
       FIG. 13  is a detailed view useful in explaining the internal structure of the connection  13 . The connection  13  has a usage detecting section operating in connection with usage of the medical apparatus and a count section for storing an experience on usage, the usage detecting section and the count section being both integrated with the connection. That is, an electric resistor  15  is provided in this area and is made, for example, of metal such as nichrome which has a high electric resistivity. The electric resistor  15  has one end connected to one  16   a  of a pair of read terminals  16   a  and  16   b . The read terminals  16   a  and  16   b  are provided along an outer periphery of a rear end of the hand-held section  6  and are connected to a read section (not shown) that is installed on the hand-held section  6 .  
      Furthermore, a movable terminal  17  is located in an internal area of the connection  13 , moves in contact with the electric resistor  15 , and is attached to an outer periphery of an endless belt  18 . The belt  18  is passed across a pair of pulleys  19 .  
      The belt  18  has a plurality of stopper projections  21  arranged on an inner surface thereof in a line at intervals along a travelling direction thereof. The belt  18  has a stopper  22  located in an inner space of the belt  18  and constituting a reverse-rotation preventing mechanism that is caught on the stopper projections  21  when the belt  18  is to rotate in a reverse direction, thereby preventing the belt  18  from being reversely rotated.  
      The belt  18  has a metallic surface provided on a surface thereof and electrically connected to the movable terminal  17 . A fixed terminal  23  fixedly installed inside the connection is always in sliding contact with the metallic surface of the belt  18 . The fixed terminal  23  is connected to the read terminal  16   b.    
      When the treatment instrument main body  2  and the vibrator unit  3  are assembled together, the pin  11  of the vibrator unit  3  advances into the internal area of the connection  13  of the treatment instrument main body  2  to come in contact with the surface of the belt  18  to frictionally rotate the belt  18  in a forward direction. That is, the belt  18  rotates by a predetermined rotational quantity each time the treatment instrument main body  2  and the vibrator unit  3  are assembled together.  
      The electric resistor  15  has a stopper projection  25  at its end located on the read terminal  16   b  side or in a neighborhood thereof, the stopper projection  25  having the movable terminal  17  coming in abutment therewith.  
      (Operation)  
      In operation, when the treatment instrument main body  2  and the vibrator unit  3  are assembled together, the pin  11  rubs against the belt  18 , which is thus rotated by a fixed amount. As the belt  18  rotates, the movable terminal  17  moves rightward in  FIG. 2 a  fixed amount to come in contact with the electric resistor  15  at a different position, thereby changing a resistance value between the read terminal  16   a  and the read terminal  16   b . That is, the resistance value increases as the movable terminal  17  moves. When the treatment instrument main body  2  and the vibrator unit  3  are mutually disconnected after operation, the frictional force causing the pin  111  to pull the belt  18  acts in the reverse direction, but the belt  18  is not reversely rotated because the stopper projections  21  are caught on the stopper  22 .  
      As a result, the movable terminal  17  is held and remains at the position to which it has been moved during assembly, with the resistance value between the read terminals  16   a  and  16   b  remaining unchanged. When the assembly of the treatment instrument main body  2  and the vibrator unit  3 , which is carried out before each operation, is repeated, the movable terminal  17  moves a fixed distance each time to increase the resistance value between the read terminals  16   a  and  16   b  in proportion to the number of assemblies (an experience-on-usage storage function).  
      Once the movable terminal  17  has reached an end point of the electric resistor  15 , it comes in abutment with the projection  25  and is hindered from further movement. In this state, the resistance value between the read terminals  16   a  and  16   b  is highest. Externally reading this resistance value enables determination of the number of times that the ultrasonic coagulation incision treatment instrument  1  has been used. Consequently, the use of the ultrasonic coagulation incision treatment instrument  1  can be stopped in accordance with a safety factor.  
      (Effects)  
      According to this embodiment, the value in proportion to the number of assemblies is retained to allow the determination of the number of times that the treatment instrument has been used (experience on usage).  
     First Variation of the Second Embodiment  
      An energy treatment system with an experience-on-usage storage function according to a first variation of the second embodiment will be described with reference to  FIGS. 14 and 15 .  
      (Configuration)  
       FIG. 14  shows a high-frequency treatment instrument  30  such as an electric scalpel which uses a high frequency as treatment energy. The high-frequency treatment instrument  30  comprises a sheath  31  and a hand-held section  32  also acting as a grip section. The sheath  31  has a treatment section  33  provided at a tip thereof. The hand-held section  32  has a gripping handle  34  and an operation handle  35 . The operation handle  35  can be rotationally moved to open or close the treatment section  33 .  
      In addition, the hand-held section  32  has a count section  36  installed at a rear end thereof to store the experience on usage, the count section  36  comprising a usage detecting section operating in connection with usage of the apparatus. A pin-shaped high-frequency electrode  37  penetrates the count section  36  and projects rearward therefrom.  
      Before the high-frequency treatment instrument  30  is operated, a connector  39  of a high-frequency supply cord  36  is connected to the high-frequency electrode  37 .  
       FIG. 15  is an explanatory drawing showing the internal structure of the count section  36  in detail. The count section  36  has a fitting recess  41  formed at a rear end thereof and into which part of the connector  39  of the high-frequency supply cord  38  advances when it is connected. The fitting recess  41  has a slidable switch operating rod  42  inside. When the connector  39  of the high-frequency supply cord  38  is connected to the high-frequency electrode  37 , the switch operating rod  42  is pushed by a tip of the connector  39  and slides in a fashion entering the count section  36 .  
      The count section  36  internally has an electric resistor  43  and a movable terminal  44  moving in contact with the electric resistor  43  and fixed to an endless belt  45 . The belt  45  is passed across a pair of pulleys  46  so as to rotate in one direction, and the pulleys  46  for rotating the belt  45  can be rotated only in one direction.  
      The belt  45  has a plurality of projections  47  formed of an elastic material such as rubber and projected outward therefrom. The projections  47  are pushed by the switch operating rod  42  when it is pushed in, thereby rotating the belt  45 . In addition, when pushed, the switch operating rod  42  returns to its original position due to a spring  48 .  
      The belt  45  has a metallic conductive portion (not shown) formed on a surface thereof like, for example, a film and electrically connected to the movable terminal  44  and also has a fixed terminal  51  that always contacts with a surface of the conductive portion even when the belt  45  rotates.  
      The electric resistor  43  has a stopper projection  52  at an inner end thereof, with which the movable terminal  44  comes in abutment. The inner end of the electric resistor  43  is connected to a read terminal  53   a . Another read terminal  53   b  is connected to the fixed terminal  51 .  
      The read terminals  53   a  and  53   b  are provided along an outer periphery of the count section  36  and connected to a read section (not shown) installed in the count section  36 .  
      (Operation)  
      Before the high-frequency treatment section  30  is operated, when the connector  39  of the high-frequency supply cord is connected, the connector  39  pushes the switch operating rod  42 . At this point of time, an inner end of the switch operating rod  42  is caught on the projections  47  on the belt  45  to push them to rotate the belt  45 . The rotation of the belt  45  moves the movable terminal  44  rightward in  FIG. 15 . Then, the resistance value between the read terminals  53   a  and  53   b  decreases consistently with the amount that the movable terminal  44  has moved.  
      After the use, when the connector of the high-frequency cord  38  is removed from the high-frequency electrode  37  of the high-frequency treatment instrument  30 , the spring  48  causes the switch operating rod  42  to return but the belt  45  does not move because the end of the operating rod  42  only slides on the projections  47  though it is temporarily caught thereon, thereby preventing the reverse rotation of the pulleys  46 . As a result, the removable terminal  44  is held at the position to which it was moved when the high-frequency supply cord  38  was connected, with the resistance value between the read terminals  53   a  and  53   b  remaining unchanged.  
      When the high-frequency treatment instrument  30  and the high-frequency supply cord  38  are repeatedly connected together before each operation, the movable terminal  44  moves a fixed distance each time to reduce the resistance value between the read terminals  53   a  and  53   b  in proportion to the number of connections (an experience-on-usage storage function). Once the movable terminal  44  has reached an end point of the electric resistor  43 , it comes in abutment with the stopper projection  52  of the electric resistor  43  and is hindered from further movement.  
      In this state, the resistance value between the read terminals  53   a  and  53   b  is lowest. Since the projections  47  are made of rubber, a fixed or larger amount of force enables the end of the switch  43  to deform the projections  47  and climb over them. This prevents the movable terminal  44  from failing to push the switch operating rod  42  through it has reached the end point of the electric resistor  43 , the failure hindering the connection of the high-frequency supply cord  38 .  
      (Effects)  
      According to this embodiment, the value in proportion to the number of connections is retained to allow the determination of the number of times that the treatment instrument has been used (experience on usage).  
     Second Variation of the Second Embodiment  
      An energy treatment system with an experience-on-usage storage function according to a second variation of the second embodiment will be described with reference to  FIG. 16 .  
      (Configuration)  
      This variation relates to the high-frequency treatment instrument  30  as described in the second embodiment, wherein the sheath  31 , the hand-held section  32 , treatment section  33 , the gripping handle  34 , the operation handle  35 , the count section  36 , the high-frequency electrode  37 , and other components are configured in the same manner as those in the second embodiment. In this embodiment, the count section  36  is counted up each time the operation handle  35  is movably operated.  
      That is, the switch operating rod (slide rod)  42  for operating the count section  36  is slidably provided in the hand-held section  32  so as to slide in connection of the movement of the operation handle  35  to activate the count section  36  when the operation handle  35  is operated.  
      (Operation)  
      In operation, when the operation handle  35  is gripped to grip a tissue, the switch operating rod  42  is pushed to push the projections  47  on the belt  45  to rotate the belt  45 . The rotation of the belt  45  moves the movable terminal  44  rightward in  FIG. 15 . Then, the resistance value between the read terminals  53   a  and  53   b  increases consistently with the amount that the movable terminal  44  has moved.  
      Returning the operation handle  35  does not move the belt  45  because the pulleys  46  do not rotate reversely. As a result, the removable terminal  44  is held at the position to which it has been moved, with the resistance value between the read terminals  53   a  and  53   b  remaining unchanged.  
      When tissues are repeatedly gripped, the movable terminal  44  moves a fixed distance each time to increase the resistance value between the read terminals  53   a  and  53   b  in proportion to the number of operations. Once the movable terminal  44  has reached the end point of the electric resistor  43 , it comes in abutment with the stopper projection  52  of the electric resistor  43  and is hindered from further movement. In this state, the electric resistance between the read terminals  53   a  and  53   b  is highest.  
      Since the projections  47  are made of rubber, a fixed or larger amount of force allows the switch operating rod  42  to climb over the projections  47 . This prevents an operator from failing to sufficiently grip the operation handle  35  through the movable terminal  44  has reached the end point of the electric resistor  43 .  
      (Effects)  
      According to this embodiment, the value in proportion to the number of operations for the treatment is retained to allow the determination of the number of times that the treatment instrument has been used (experience on usage).  
      Although the high-frequency treatment instrument has been shown, the treatment instrument may not be for high frequency treatments as long as it has a movable operation handle.  
     Third Variation of the Second Embodiment  
      An energy treatment system with an experience-on-usage storage function according to a third variation of the second embodiment will be described with reference to  FIG. 17 .  
      (Configuration)  
      This variation also relates to the high-frequency treatment instrument  60 . A hand-held gripping section  61  of the high-frequency treatment instrument  60  has a pair of high-frequency connection terminals  62   a  and  62   b  projected from a rear end thereof and to which high-frequency power supply cords (not shown) are connected. The hand-held gripping section  61  internally has a power supply section  63  for generating a DC voltage from a high frequency and a memory built-in count section  64 . The power supply section  63  has an output end connected to the memory built-in count section  64 . The hand-held gripping section  61  has a read section  65  on an external surface portion thereof. A value in a memory of the memory built-in count section  64  is output to the read section  65  as a binary number.  
      The other part of the configuration of the high-frequency treatment instrument is similar to that of the above described first or second embodiment.  
      (Operation)  
      When a high frequency is conducted through the high-frequency treatment instrument  60  for high-frequency coagulation or incision, a DC voltage is output from the power supply section  63  for a predetermined amount of time. The DC voltage activates the memory built-in section  64  to increment an output count number by one upon each activation. The number of previous outputs can be determined by reading the value in the read section  65 .  
      (Effects)  
      This variation allows the number of electric connections through the treatment instrument  60  to be determined to more accurately determine the number of times that the treatment instrument  60  has been used.  
     Fourth Variation of the Second Embodiment  
      An energy treatment system with an experience-on-usage storage function according to a fourth variation of the second embodiment will be described with reference to  FIG. 18 .  
      (Configuration)  
      This variation also relates to a high-frequency treatment instrument  70 . A hand-held gripping section  71  of the high-frequency treatment instrument  70  has high-frequency connection terminals  73   a  and  73   b  projected from a rear end thereof and to which high-frequency power supply cords  72  with memory access lines are connected. Further, the hand-held gripping section  71  has a memory interface connector  74  at a rear end thereof. The memory interface connector  74  has a signal line connected to a memory  75  provided inside the hand-held gripping section  71 .  
      The other part of the configuration of the high-frequency treatment instrument is similar to that of the above described embodiments.  
      (Operation)  
      To operate the high-frequency treatment instrument  70 , the high-frequency power supply cords  72  with memory access lines are connected to the high-frequency connection terminals  73   a  and  73   b . This enables a high-frequency power supply (not shown) to supply high-frequency energy for treatment to the high-frequency treatment instrument  70  via the high-frequency connection terminals  73   a  and  73   b . Further, a signal from an apparatus main body (not shown) is communicated to the memory  75  through the memory access lines and via the memory interface connector  74  so that the number of times that the high-frequency treatment instrument  70  has been used or the amount of time for which it has been used is stored in the memory  75 . For example, the number of outputs can be accumulated and stored upon each output. Alternatively, the amount of time for which high-frequency energy has been output can be accumulated and stored. Then, that the life of the high-frequency treatment instrument  70  is nearly over can be determined from the number of previous operations or the amount of operation time stored in the memory  75 .  
      In addition, if the high-frequency treatment instrument  70  is connected to the apparatus main body (not shown) via the high-frequency power supply cords  72  with memory access lines, the apparatus main body may arbitrarily rewrite the contents of the memory  75  in the high-frequency treatment instrument  70 . Alternatively, the apparatus main body can, for example, accumulate and store the number of outputs upon each output.  
      In addition, the contents of the memory  75  can be displayed on the apparatus main body to inform the user that the life of the high-frequency treatment instrument  70  is nearly over.  
      (Effects)  
      This variation enables arbitrary information on the experience on usage of the high-frequency treatment instrument  70  to be stored in the high-frequency treatment instrument  70  to inform the user that the life of the high-frequency treatment instrument  70  is nearly over.  
      Although the high-frequency treatment instrument has been illustrated, the present invention is not limited to this treatment instrument.  
     Fifth Variation of the Second Embodiment  
      An energy treatment system with an experience-on-usage storage function according to a fifth variation of the second embodiment will be described with reference to FIGS.  19  to  21 .  
      (Configuration)  
      This variation also relates to a high-frequency treatment instrument  80 . As shown in  FIG. 19 , a hand-held gripping section  81  of the high-frequency treatment instrument  80  has a flexible cable  82  connected to a rear end thereof, and the cable  82  has a high-frequency connector  83  provided at an extended end thereof.  FIG. 19  shows the portion of the high-frequency connector  83  in an enlarged view.  
      The high-frequency connector  83  has a pair of high-frequency connection terminals  84   a  and  84   b  and an ID pin  85  for identifying an individual. The ID pin  85  is made of a electrically insulated material and has annular metallic identifying terminals  86  on a surface thereof. The illustrated identifying terminals  86  are positioned so that up to eight such terminals are arranged at equal intervals. The ID of the high-frequency treatment instrument  80  is represented by a binary number based on the number and arrangement of the identifying terminals  86 .  
      The high-frequency connector  83  of the high-frequency treatment instrument  80  is connected to an apparatus main body  90  as shown in  FIG. 20 . The apparatus main body  90  has an ID pin hole  91  into which the ID pin  85  of the high-frequency connector  83  to be connected is inserted and which internally has a plurality of contacts  92  arranged at equal intervals in eight pairs in such a manner that the contacts  92  of each pair are mutually opposed.  
      The interval between the pairs is the same as that between any two of the eight identifying terminals  86  arranged on the ID pin  85  so that the contacts  92  are electrically connected to the identifying terminals  86 . In addition, the contacts  92  are mutually electrically insulated and connected to a contact detecting circuit  94  via a multiconductor cable  93 .  
      Additionally, as shown in  FIG. 21 , the apparatus main body internally has a control section  95 , a memory  96 , an output section  97 , and a display section  98 , in addition to the above described contact detecting circuit  94 .  
      (Operation)  
      Before the high-frequency treatment instrument  80  is operated, when the high-frequency connector  83  is connected to the apparatus main body  90 , the ID pin  85  advances into the ID pin hole  91  and only the identifying terminals  86  on the ID pin  85  are electrically connected to the contacts  92 . Then, the contact detecting circuit  94  checks all the opposed pairs of contacts  92  for electric conduction to determine the ID of the connected high-frequency treatment instrument  80 .  
      When the contact detecting circuit  94  outputs data in connection with an operation of the high-frequency treatment instrument  80 , the control section  95  stores the experience on usage such as the output duration or the number of previous outputs in the memory  96  for each ID (the experience-on-usage storage function). At this point, if information has already been stored on the same ID, the experience on usage is added to the contents of the already stored information for storage. Additionally, the contents of the memory  96  can be arbitrarily displayed on a display section of the apparatus main body  90 . This can inform the user of the experience on usage of the high-frequency treatment instrument or that its life is nearly over.  
      The high-frequency treatment instrument has been described, but apparently the present invention is not limited to this treatment instrument. The number of pairs of identification terminals  86  or of opposed pairs of contacts  92  may be increased or reduced.  
      (Effects)  
      This variation enables arbitrary information on the experience on usage of the treatment instrument to be stored and communicated to the user.  
     Sixth Variation of the Second Embodiment  
      An energy treatment system with an experience-on-usage storage function according to a sixth variation of the second embodiment will be described with reference to  FIG. 22 .  
      (Configuration)  
      This variation relates to an ultrasonic treatment instrument  100  with a bar code comprising a hand-held section  101  and a sheath  102 . The sheath  102  has a closable treatment section  103  at a tip thereof. The hand-held section  101  has a fixed handle  104  and a movable handle  105 . The movable handle  105  can be operated to open or close the treatment section  103 . The hand-held section  101  has a bar code  106  on an external surface indicating the type or ID number of the ultrasonic treatment instrument  100 .  
      The hand-held section  101  has a connection code  107  connected thereto. The connection code  107  is connected to an apparatus main body  110  also acting as a power supply.

The apparatus main body also has a memory (not shown) inside; the contents stored in this memory can be displayed on the display section  113 .  
      (Operation)  
      To operate the ultrasonic treatment instrument  100 , before starting outputs, the bar code  106  is applied to the bar code reading section  112  to register the ultrasonic treatment instrument  100  used.  
      Whenever the ultraviolet treatment instrument  100  is used, its operation is detected so that the experience on usage such as the output duration or the number of previous outputs is stored in a memory (not shown) inside the main apparatus main body  110  for each ID of the ultrasonic treatment instrument  100 . At this point, if information has already been stored on the same ID, the experience on usage is added to the contents of the already stored information for storage. Additionally, the contents of this memory can be arbitrarily displayed on the display section  113  to inform the user that the life of the ultrasonic treatment instrument  100  is nearly over.  
      The ultrasonic treatment instrument has been described, but apparently the present invention is not limited to this treatment instrument.  
      (Effects)  
      This variation enables arbitrary information on the experience on usage of the treatment instrument to be stored and communicated to the user, as in the above described fifth variation.  
     Seventh Variation of the Second Embodiment  
      An energy treatment system with an experience-on-usage storage function according to a seventh variation of the second embodiment will be described with reference to  FIG. 23 .  
      (Configuration)  
      The seventh variation relates to an ultrasonic treatment instrument  120  with a bar code. Similarly to the above described ultrasonic treatment instrument, this treatment function comprises a hand-held section  121  and a sheath  122  having a closable treatment section  123  at a tip thereof. The hand-held section  121  has a fixed handle  124  and a movable handle  125 . The movable handle  125  can be operated to open or close the treatment section  123 .  
      The hand-held section  121  has, on its external surface, a bar code  126  indicating the type or ID number of the ultrasonic treatment instrument  100  and read terminals  127   a  and  127   b  through which a value that varies with the number of times that the ultrasonic treatment instrument  120  has been used can be read using a portable treatment instrument checking device, described later. A mechanism integrated with the ultrasonic treatment instrument to store and hold the number of previous operations may be any one of the mechanisms according to the above described embodiments from the second embodiment to the third variations thereof.  
      According to this variation, the portable treatment instrument checking device  130  is provided separately from the ultrasonic treatment instrument  120 . The portable treatment instrument checking device  130  has a display panel  131  and a bar code reader  132  and a read connector  133  connected thereto via cables  134  and  135 , respectively. The main body of the portable treatment instrument checking device  130  stores information on various treatment instruments.  
      (Operation)  
      The portable treatment instrument checking device  130  is activated, and the bar code  126  of the ultrasonic treatment instrument  120  is read using the bar code reader  132 . The read type of the ultrasonic treatment instrument  120  is displayed on the display panel  131 . Next, the read connector  133  is connected to the read terminals  127   a  and  127   b . Then, the number of previous operations is displayed on the display panel  131 , and the percentage of the displayed number with respect to a specified number of operations is also shown depending on the type of the ultrasonic treatment instrument  120  recognized from the bar code  126 .  
      Although the ultrasonic treatment instrument has been illustrated, the present invention is not limited to this treatment instrument.  
      (Effects)  
      This variation enables the user to easily determined when to replace the treatment instrument. Since the treatment instrument checking device is portable, this variation is also effective when service personnel conduct maintenance work.  
      (Eighth Variation of the Second Embodiment)  
      An energy treatment system with an experience-on-usage storage function according to an eighth variation of the second embodiment will be described with reference to  FIG. 24 .  
      (Configuration)  
       FIG. 13  is a block diagram of a main body  140  of a treatment system. The main body  140  belongs to, for example, an electric scalpel, an ultrasonic operating apparatus, a high-frequency treatment apparatus, a microwave treatment apparatus, or a hyperthermia apparatus and is not particularly limited.  
      The main body  140  has a control section  141 , and an operation section  142 , an output section  143 , a display section  144 , an inspection recording section  145 , and an output duration (usage quantity) accumulating section  146  which are all linked to the control section  141 . The inspection recording section  145  records the last inspection date and has a date managing function to allow the user to determine how many days have passed since the recorded inspection date. The inspection recording section  145  and the output duration accumulating section  146  each have a built-in memory that holds contents even after the power supply has been turned off so that an output duration measured by the output duration measuring section  147  is accumulatively recorded.  
      (Operation)  
      When the user operates the operation section  142 , the output section  143  provides a required output. The output duration is measured by the output duration measuring section  147  and an accumulated duration is recorded in the output duration accumulating section  146 . If the accumulated output duration exceeds a predetermined value, for example, 10 hours, the control section  141  uses a display function such as a LED on the display section  144  to inform the user of a recommended inspection period. Alternatively, if a predetermined number of days, for example, 365 days have passed since the last inspection date recorded in the inspection recording section  145 , the control section  141  uses the display function such as a LED on the display section  144  to inform the user of a recommended inspection period.  
      Whatever condition has triggered the display of the recommended inspection, the apparatus can be used as usual without affecting the original functions.  
      If the apparatus has been inspected, the new inspection date is recorded in the inspection recording section  145  and the accumulated duration in the output duration accumulating section  146  is cleared to zero.  
      (Effects)  
      This variation can notify the user of an appropriate inspection period depending on the usage status based on the output experience or the number of days passed. In addition, since no error has occurred, the apparatus can be normally used despite the notification and inspected so as not to disturb the user&#39;s operation schedule.  
     Ninth Variation of the Second Embodiment  
      An energy treatment system with an experience-on-usage storage function according to a ninth variation of the second embodiment will be described with reference to  FIG. 25 .  
      (Configuration)  
       FIG. 25  is a block diagram of the main body  140  of a treatment system. The main body  140  belongs to, for example, an electric scalpel, an ultrasonic operating apparatus, a high-frequency treatment apparatus, a microwave treatment apparatus, or a hyperthermia apparatus and is not particularly limited.  
      The main body  140  has the control section  141 , and the operation section  142 , the output section  143 , the display section  144 , the inspection recording section  145 , and the usage quantity (output duration) accumulating section  146  which are all linked to the control section  141 .  
      The inspection recording section  145  and the output duration accumulating section  146  each have a built-in memory that holds contents even after the power supply has been turned off. The inspection recording section  145  records the last inspection date and has a date managing function to allow the user to determine how many days have passed since the recorded inspection date. In addition, the usage quantity accumulation section  146  accumulatively records usage quantities measured by the usage quantity measuring section  148 .  
      (Operation)  
      When the user operates the operation section  142 , the output section  143  provides a required output. At this point, the usage quantity measuring section  148  calculates a usage quantity using output parameters such as a set power, a set temperature, and an output mode as well as the output duration, based on a predetermined function. For example: 
      (1) Usage quantity=set power×output duration     (2) Usage quantity=2×(set temperature−37)×output duration     (3) Usage quantity=output mode No.×output duration    

      The calculated usage quantity is recorded in the usage quantity accumulating section  146 . If the accumulated usage quantity exceeds a predetermined value, the control section  141  uses the display function such as a LED on the display section  144  to inform the user of a recommended inspection period. Alternatively, if a predetermined number of days, for example, 365 days have passed since the last inspection date recorded in the inspection recording section  145 , the control section  141  uses the display function such as a LED on the display section  144  to inform the user of a recommended inspection period.  
      Whatever condition has triggered the display of the recommended inspection, the apparatus can be used as usual without affecting the original functions.  
      If the apparatus has been inspected, the new inspection date is recorded in the inspection recording section  145  and the accumulated usage quantity in the usage quantity accumulating section  146  is cleared to zero.  
      (Effects)  
      This variation enables weighting based on the output conditions with the characteristics of the apparatus taken into account to notify the user of an appropriate inspection period depending on the usage conditions.  
      The above described second embodiment solves the problem with the prior art that the previous experience on usage is unknown when the apparatus fails, and enables the user to replace the treatment instrument with a new one at an optimal time before a trouble occurs.  
      That is, possible troubles can be reduced by storing the number of times that the treatment instrument has been used to determine that the specified usage quantity has been reached and checking the usage quantity of the treatment instrument to replace it with a new one at a replacement time. This enables provision of a medical apparatus compatible with the medical apparatus lease system.
