1. Embodiment

Overall Configuration of Electromedical Device System5

FIG.1schematically illustrates an overall configuration example of an electromedical device system5according to an embodiment of the present disclosure. The electromedical device system5is a system used in performing a treatment or the like in a body of a patient. The treatment or the like includes treatment such as ablation (cauterization) on the affected area, incision and the like. Since the “power supply method” in the present disclosure is embodied in the electromedical device system of the present disclosure, it will be described together below.

The electromedical device system5includes a power supply device3, one or more relay devices6(three relay devices6a,6b, and6cin the example ofFIG.1), and electromedical devices1(three electromedical devices1a,1b, and1cin the example ofFIG.1) individually connected to each relay device6. A patient plate4, for example, is also used as appropriate when a treatment or the like using the electromedical device system5is performed.

A control system configured by the power supply device3and the relay device6corresponds to a specific example of an “electromedical device control system” in the present disclosure.

Electromedical Device1

The electromedical device1is a device used when performing the treatment or the like described above, and includes a device body11and one or more electrodes111. The electromedical device1includes, for example, an ablation catheter, an electrode needle, and an electrical scalpel.

The electrode111is disposed near the distal end of the elongated device body11. In the example ofFIG.1, one or more electrodes111are provided near the distal end of the device body11. Specifically, in the electromedical device1a, one electrode111is provided near the distal end of the device body11. In the electromedical device1b, the distal end side of the device body11is branched into two, and one electrode111(a total of two electrodes111) is provided near the distal end of each branched portion. In the electromedical device1c, a plurality of the electrodes111are provided near the distal end of the device body11.

In other words, the electromedical device1ais of a monopolar type in which treatment or the like is performed between one electrode111and the patient plate4(another electrode). Each of the electromedical devices1band1cis of a bipolar type in which treatment or the like is performed between a plurality of the electrodes111. It should be noted that, for example, a monopolar type in which treatment or the like is performed between a plurality of electrodes and a patient plate (another electrode) on the electromedical device may be used.

Relay Device6

The relay device6relays between the electromedical device1and the like and the power supply device3. Specifically, the relay device6arelays between the power supply device3and a set including the electromedical device1aand the patient plate4. The relay device6brelays between the electromedical device1band the power supply device3. The relay device6crelays between the electromedical device1cand the power supply device3.

The relay device6aincludes an input terminal Tin61connected to the power supply device3via a connection cable C1, an output terminal Tout62connected to the electromedical device1avia a connection cable C2, and an input terminal Tin62to which the patient plate4is connected via a connection cable C3. The relay devices6band6ceach include an input terminal Tin6connected to the power supply device3via the connection cable C1, and an output terminal Tout6connected to the electromedical device1bor the electromedical device1cvia the connection cable C2. In the example ofFIG.1, one selected connection cable C1of the three connection cables C1individually connected to the relay devices6a,6b, and6cis connected to an output terminal Tout3(a terminal to which electric power Pout or the like is output) of the power supply device3as indicated by the dashed arrow. In other words, when the electromedical device1is used, only the relay device6corresponding to the electromedical device1to be used is connected to the power supply device3.

For example, the output terminals Tout6and Tout62may have different shapes for each of the relay devices6a,6b, and6cto prevent erroneous connection of the electromedical device1to the relay device6.

Each of the input terminals Tin6and Tin61corresponds to a specific example of an “input unit” in the present disclosure. Each of the output terminals Tout6and Tout62corresponds to a specific example of an “output unit” in the present disclosure.

A detailed configuration example of the relay device6will be described later (FIGS.2to5).

Power Supply Device3

The power supply device3supplies electric power Pout (for example, radio-frequency (RF) electric power) for performing treatment or the like to the electromedical device1. Specifically, the power supply device3supplies the electric power Pout from the output terminal Tout3to the electromedical device1via the connection cable C1, the relay device6, and the connection cable C2.

A detailed configuration example of the power supply device3will be described later (FIGS.2to5).

Patient Plate4

The patient plate4is used in a state of being attached to the body surface of a patient9when a treatment or the like is performed. In the example ofFIG.1, radio-frequency energization is performed (the electric power Pout is supplied) between the electrode111and the patient plate4when treatment or the like is performed using the electromedical device1a.

Detailed Configuration of Power Supply Device3and Relay Device6

Next, detailed configuration examples of the power supply device3and the relay device6will be described with reference toFIGS.2to5in addition toFIG.1.

FIG.2is a block diagram illustrating an example of the detailed configuration of the electromedical device system5(an example in which the electromedical device1aand the patient plate4are connected to the power supply device3via the relay device6a).

Power Supply Device3

The power supply device3includes an input unit31, a power supply unit32, a control unit33, a display unit34, and a determination unit35, as illustrated inFIG.2.

The input unit31is a portion that outputs an instruction signal (operation signal) for indicating various types of setting values or predetermined operation. The operation signal is output from the input unit31to the control unit33in response to an operation on a button or the like by an operator (for example, a technician) of the power supply device3. However, some of the setting values may not be input according to the operation by the operator, but may be set in advance in the power supply device3at the time of shipment of the product, for example.

The power supply unit32outputs the electric power Pout according to the control by the control unit33. The power supply unit32includes a predetermined power supply circuit (for example, a switching regulator). For example, when the electric power Pout is radio-frequency electric power, the frequency of the electric power Pout is approximately 450 kHz to 550 kHz (suitably 500 kHz).

The control unit33is a unit that controls the entire power supply device3and performs predetermined arithmetic processing. The control unit33and the determination unit35are configured using, for example, a microcomputer or the like. The control unit33controls, for example, the supply operation of the electric power Pout in the power supply unit32and the display operation in the display unit34.

The display unit34is a unit (monitor) that displays various pieces of information and outputs these pieces of information to the outside. The display unit34is configured using a display according to various modes (for example, a liquid crystal display, a cathode ray tube (CRT) display, or an organic electro luminescence (EL) display).

The determination unit35uses the relay device6connected to the power supply device3(output terminal Tout3) to perform predetermined determination (determination regarding the type of the electromedical device1connected to the relay device6). The determination unit35inputs and outputs various pieces of information to and from an information storage unit61in the relay device6and the control unit33. In addition, details such as the content of determination by the determination unit35will be described later (FIGS.4and5).

Relay Device6

The relay device6(relay device6a) further includes the information storage unit61.

The information storage unit61stores determination information610that is information used for determination by the determination unit35. The determination information610is defined according to the type of the (connection destination) electromedical device1connected to the relay device6, and includes bit information IB defined mechanically or electrically. When the determination information610includes electrically defined bit information IB, the information storage unit61is configured using, for example, a memory (storage unit) of various storage methods. When the determination information610includes mechanically defined bit information IB, the information storage unit61and the determination information610are each implemented by, for example, the mechanical structure illustrated inFIG.3below.

FIG.3is a circuit diagram selectively and schematically illustrating an example of detailed configuration of part related to determination according to the present embodiment (a configuration example in which the mechanically defined bit information IB is included as the determination information610).

In the example ofFIG.3, the information storage unit61has three switches Sa, Sb, and Sc that constitute the determination information610including mechanically defined bit information IB. Specifically, information indicating the state (ON state or OFF state) of each of the switches Sa, Sb, and Sc corresponds to the bit information IB (information of each bit: “0” or “1”) as the determination information610. The switch Sa is arranged between a wire La connected to the determination unit35in the power supply device3and a wire LG connected to the ground. The switch Sb is arranged between a wire Lb connected to the determination unit35and the wire LG, and the switch Sc is arranged between a wire Lc connected to the determination unit35and the wire LG. The wires La, Lb, and Lc are individually connected to wires from a power supply VD via resistors R, respectively.

In the example ofFIG.3, the switches Sa and Sb are set to the OFF state (open state of the wire), and the switch Sc is set to the ON state (short state of the wire). As a result, as indicated by dashed arrows inFIG.3, a current ID of a predetermined value or more (for example, a current slightly less than 1 [mA]) flows from the power supply VD to the ground via the resistor R, the wire Lc, the switch Sc, and the wire LG. On the other hand, a current ID of a predetermined value or more does not flow through the wires La and Lb and the switches Sa and Sb. Even when each of the switches Sa, Sb, and Sc is in the OFF state, a very small current less than a predetermined value (for example, a current of slightly less than 1 [μA]) flows from the power supply VD through the inside (for example, an input resistor of 10 [MΩ]) of the determination unit35.

The determination unit35determines the content of the bit information IB (3-bit bit information IB in the example ofFIG.3) based on the voltage states on the wires La, Lb, and Lc. That is, when the switches Sa, Sb, and Sc are set to the ON state, since the voltage state on the wires La, Lb, and Lc is at the ground level (“L (low)” level), the determination unit35determines that the bit information IB of that bit is “0”. When the switches Sa, Sb, and Sc are set to the OFF state, since the voltage state on the wires La, Lb, and Lc is at the power supply VD level (“H (high)” level), the determination unit35determines that the bit information IB of that bit is “1”. Therefore, in the example ofFIG.3, when the 3-bit bit information IB is illustrated in the order of each voltage state on the wires La, Lb, and Lc, the 3-bit bit information IB is determined as “110”. Note that the arrangement order of each bit is not limited to the example inFIG.3, and can be set freely. The content of the determination information610including the bit information IB is individually set for each type (type of the relay device6) of the electromedical device1connected to the relay device6.

FIG.4illustrates an example of a truth table Tb used for determination according to the present embodiment. Specifically, the truth table Tb illustrates an example of correspondence between the content of the determination information610(bit information IB) and the output mode of the electric power Pout from the power supply device3.FIG.5illustrates an example of information included as the type of the electromedical device1.

In the present embodiment, the power supply device3(power supply unit32) outputs the electric power Pout in an output mode corresponding to the type of the electromedical device1connected to the relay device6obtained by determination using the relay device6(determination by the determination unit35). In other words, the power supply device3outputs the electric power Pout to the electromedical device1connected to each relay device6in a different output mode for each type of the relay device6(electromedical device1). At this time, the electric power Pout output from the power supply device3is output to the connection destination electromedical device1via the input terminal (input terminal Tin6or input terminal Tin61) and the output terminal (output terminal Tout6or output terminal Tout62) of the relay device6. Here, the “output mode” includes the type of the electromedical device1to be described later, or a setting value set by the operator within the range of the type of the electromedical device1.

For example, as illustrated inFIG.4, the determination unit35determines the connection status (connected state or non-connected state) of the relay device6to the power supply device3and the type of the electromedical device1connected to the relay device6based on the determined content of the determination information610. For example, as illustrated inFIG.5, the type of the electromedical device1includes at least one piece of information of the output format of the electromedical device1, the operation mode when using the electromedical device1, and the maximum output electric power of the electromedical device1. Specific examples of the content of the output format, operation mode, and maximum output electric power are as follows, as illustrated inFIG.5.Output format: Unipolar type/bipolar typeOperation mode: Coagulation mode/incision modeMaximum output electric power: 50 [W]/100 [W]/200 [W]/others

A specific example of the output mode of the electric power Pout corresponding to the content of the determination information610(bit information IB) is as follows, as illustrated in the truth table Tb ofFIG.4.FIG.4also illustrates whether output of the electric power Pout is enabled in each state (IB=other than “111”: Output of Pout enabled, IB=“111”: Output of Pout disabled). In addition, the contents such as the above-described output format, operation mode, and maximum output electric power are individually set for each of “output mode A” to “output mode G”.IB=“000”: Output mode AIB=“001”: Output mode BIB=“010”: Output mode CIB=“011”: Output mode DIB=“100”: Output mode EIB=“101”: Output mode FIB=“110”: Output mode GIB=“111”: (Relay device6: non-connected state)

Operation and Advantages and Effects

A. Basic Operation

In the electromedical device system5, a treatment or the like is performed on the affected area of the patient9. In performing the treatment or the like, the device body11is inserted into the body of the patient9from its distal end. The electric power Pout (for example, radio-frequency electric power) is supplied between the electrode111near the distal end of the device body11and the patient plate4from the power supply device3, so that the treatment or the like by the Joule heat generation is performed on the affected area in the body of the patient9.

By the way, in a conventional general electromedical device system, the electromedical device itself contains identification information (for example, information indicating the type of the electromedical device), and the identification information is used to determine the type (output specifications such as maximum output electric power) of the electromedical device. However, when identification information is contained in a disposable electromedical device, it may lead to an increase in cost or size of the electromedical device. Further, for example, by providing a plurality of types of connectors (electric power output terminals) in the power supply device, it is possible to prepare variations in output specifications to some extent. However, the size of the housing of the power supply device increases, the number of types of output specifications is limited by the type of the connector, and the convenience is impaired.

As described above, in a general electromedical device system, it can be said that it is difficult to improve the convenience while achieving size reduction.

B. Determination Processing and the Like

Therefore, in the electromedical device system5of the present embodiment, the determination unit35uses the relay device6to determine the type and the like of the connection destination electromedical device1. In other words, in the present embodiment, such determination is performed using a non-disposable (reusable) relay device6instead of a disposable (single-use) electromedical device1. Hereinafter, determination processing and the like according to the present embodiment will be described in detail with reference toFIG.6in addition toFIGS.1to5.

FIG.6is a flowchart illustrating an example of determination processing and the like according to the present embodiment.

In the series of processes illustrated inFIG.6, when the power supply device3is activated, first, the determination unit35reads the bit information IB (determination information610) (step S11). Next, the determination unit35determines whether or not the content of the read bit information IB is other than IB=“111” (whether or not the relay device6is in the connected state) (step S12). If it is determined that IB is other than “111” (the relay device6is in the connected state) (step S12: Y), the process proceeds to step S17, which will be described later.

On the other hand, if it is determined that IB=“111” (the relay device6is in the non-connected state) (step S12: N), a standby state is created for a predetermined time (for example, about several seconds) (step S13). After that, the determination unit35reads the bit information IB again (step S14), and determines again whether IB is other than “111” (step S15). If it is determined that IB is other than “111” (the relay device6is in the connected state) (step S15: Y), the process proceeds to step S17, which will be described later. On the other hand, if it is determined again that IB=“111” (the relay device6is in the non-connected state) (step S15: N), a message prompting connection of the relay device6is output (for example, displayed on the display unit34) (step S16). After that, the process returns to step S13(standby state for predetermined time).

In step S17described above, the determination unit35sets the output mode to that based on the truth table Tb according to the content of the read bit information IB (step S17). Next, the power supply device3(power supply unit32) performs operation in a set output mode (energization by the output of the electric power Pout, or operation of non-energization as standby state) according to an operation signal (operator's operation) output from the input unit31(step S18).

Subsequently, the determination unit35determines whether or not the content of the bit information IB has changed thereafter (step S19). If it is determined that the content of the bit information IB has not changed (step S19: N), the process returns to step S18. On the other hand, if it is determined that the content of the bit information IB has changed (step S19: Y), the determination unit35determines whether or not the electric power Pout is in an output state (energized state) (step S20). This is because there is a possibility that the content of the bit information IB will change due to a noise signal during the energization in the output period (energization period) of the electric power Pout.

When it is determined that the electric power Pout is in the output state (output period) (step S20: Y), the process returns to step S18. That is, since there is a possibility that the content of the bit information IB may change due to the noise signal during the energization in the output period of the electric power Pout, the determination unit35does not perform determination (resetting of the output mode in step S17) based on the content of the bit information IB after the change.

On the other hand, when it is determined that the electric power Pout is not in the output state (in the output stop period) (step S20: N), the following is performed. That is, in this case, the determination unit35reads the bit information IB after the change (step S21), and determines whether IB is other than “111” (whether the relay device6is in the connected state) again (step S22). This is to determine whether or not the change in the content of the bit information IB is caused by the replacement of the relay device6connected to the power supply device3(the work of temporarily removing the relay device6).

If it is determined that IB is other than “111” (the relay device6remains in the connected state) (step S22: Y), the process returns to step S18. In other words, in this case, it is determined that the change in the content of the bit information IB is not caused by the replacement of the relay device6(for example, the change in the content is caused by other noise signals other than during energization). Therefore, in this case as well, the determination based on the content of the bit information IB after the change (resetting of the output mode in step S17) is not performed.

On the other hand, if it is determined that IB=“111” (transition to the non-connected state of the relay device6) (step S22: N), the process proceeds to step S13(standby state for a predetermined time). That is, in this case, it is determined that the change in the content of the bit information IB is caused by the replacement of the relay device6(the work of temporarily removing the relay device6), and standby is performed until the relay device6after the replacement is connected to the power supply device3. In this manner, when detecting a change in the content of the bit information IB (determination information610) in the output stop period of the electric power Pout, the determination unit35performs the following. That is, after passing through the non-connected state of the relay device6(that is, after passing through “S22: N”→S13→S14→“S15: Y”), the determination unit35performs determination (step S17) based on the content of the bit information IB after the change. Also, in this case, a message prompting the connection of the relay device6is not output (step S16), and the process proceeds to the standby state (step S13). It should be noted that even if the relay device6is replaced without turning off the power and resetting, and the like, the driving of the relay device6is not hindered.

As a result, the series of processes illustrated inFIG.6ends.

C. Advantages and Effects

In this way, in the present embodiment, the electric power Pout is supplied from the power supply device3in an output mode corresponding to the type of the electromedical device1connected to the relay device6obtained by the determination using the relay device6that relays between the electromedical device1and the power supply device3. In other words, the electric power Pout is supplied from the power supply device3to the electromedical devices1connected to each relay device6in different output modes for each type of the relay device6(electromedical device1).

As a result, unlike the general electromedical device system described above, in the present embodiment, the scalability of the output mode of the electric power Pout is enhanced (variations in the output mode is ensured) while avoiding an increase in the size of the electromedical device1and the power supply device3. As a result, in the present embodiment, it is possible to improve convenience while achieving size reduction.

In the present embodiment, since the determination is not performed in the output period of the electric power Pout from the power supply device3, an erroneous determination caused by a noise signal during energization (execution of determination based on the bit information IB whose content has changed due to the noise signal during energization) can be avoided. As a result, the determination accuracy in the determination unit35is improved, and the convenience can be further improved.

In the present embodiment, when it is detected that the content of the determination information610(bit information IB) has changed in the output stop period of the electric power Pout, the determination based on the content of the determination information610after the change is performed only after passing through the non-connected state of the relay device6, so that the following advantages and effects are obtained. That is, since the determination based on the content of the determination information610after the change is performed only when the relay device6connected to the power supply device3is replaced, erroneous determination based on the change in the content due to other noise signals other than during energization, for example, can be avoided. As a result, the determination accuracy in the determination unit35is improved, and the convenience can be further improved.

2. Modified Examples

Next, modified examples (Modified Examples 1 and 2) of the above-described embodiment will be described. The same components as those in the embodiment are designated by the same reference numerals, and the description thereof will be omitted as appropriate.

Modified Example 1

Configuration and Operation

FIG.7schematically illustrates an overall configuration example of an electromedical device system5A according to Modified Example 1. Unlike the electromedical device system5, the electromedical device system5A performs determination using the electromedical device1as well as the relay device6, as will be described later.

The electromedical device system5A includes a power supply device3A, one or more relay devices6(two relay devices6band6din the example ofFIG.7), and electromedical devices1(three electromedical devices1b,1a1, and1a2in the example ofFIG.1) individually connected to each relay device6. The patient plate4, for example, is also used as appropriate when a treatment or the like using the electromedical device system5A is performed.

In the example ofFIG.7, as in the example ofFIG.1, one selected connection cable C1of the two connection cables C1individually connected to the relay devices6band6dis connected to the output terminal Tout3(a terminal to which the electric power Pout or the like is output) of the power supply device3A.

A control system configured by the power supply device3A and the relay device6corresponds to a specific example of an “electromedical device control system” in the present disclosure.

In relay device6d, the number of output terminals Tout62is changed (changed from one to two) in the relay device6a(FIG.1). The two output terminals Tout62are individually connected to the electromedical devices1a1and1a2via the connection cables C2. That is, only one of the two electromedical devices1a1and1a2is connected to the relay device6d, or both of the two electromedical devices1a1and1a2are simultaneously connected to the relay device6d.

The power supply device3A includes a determination unit35A instead of the determination unit35of the power supply device3(FIG.1), and other configurations are basically the same.

FIG.8is a circuit diagram selectively and schematically illustrating an example of detailed configuration of part related to determination according to Modified Example 1 (a configuration example in which the mechanically defined bit information IB is included as determination information610A). The electromedical device system5A illustrated inFIG.8illustrates an example in which the electromedical device1a1and the patient plate4are connected to the power supply device3A via the relay device6d.

The relay device6dincludes an information storage unit61A having the determination information610A instead of the information storage unit61having the determination information610in the relay device6(relay device6a) illustrated inFIGS.2and3.

The information storage unit61A, similarly to the information storage unit61, has the determination information610A including the bit information IB. However, the information storage unit61A has two connection pins Pd and Pe in addition to the three switches Sa, Sb, and Sc provided in the information storage unit61. That is, the information indicating the state (ON state or OFF state) of each of the switches Sa, Sb, and Sc and each of the connection pins Pd and Pe corresponds to the bit information IB (information of each bit: “0” or “1”) as the determination information610A. The connection pin Pd is arranged between a wire Ld connected to the determination unit35A in the power supply device3A and the wire LG connected to the ground. The connection pin Pe is arranged between a wire Le connected to the determination unit35A in the power supply device3A and the wire LG.

For example, as illustrated inFIG.8, the electromedical device1a1can be connected to the connection pin Pd via a wire L21included in the connection cable C2. The electromedical device1a2can be connected to the connection pin Pe via the wire included in the connection cable C2. In the example ofFIG.8, the electromedical device1a1is connected only to the connection pin Pd of the two connection pins Pd and Pe. That is, the connection pin Pd is set to the ON state (short state of the wire), and the connection pin Pe is set to the OFF state (open state of the wire). As a result, as indicated by dashed arrows inFIG.8, a current ID of a predetermined value or more flows from the power supply VD toward the ground via the resistor R, the wire Ld, the connection pin Pd, the wire L21, and the wire LG. On the other hand, the current ID of a predetermined value or more does not flow through the wire Le and the connection pin Pe. As in the example ofFIG.3, even when the switches Sa, Sb, and Sc or the connection pins Pd and Pe are in the OFF state, a very small current less than a predetermined value flows from the power supply VD through the inside of the determination unit35.

The determination unit35A determines the content of the bit information IB (5-bit bit information IB in the example ofFIG.8) based on the voltage states on the wires La to Le. That is, when the switches Sa, Sb, and Sc or the connection pins Pd and Pe are set to the ON state, since the voltage state on the wires La to Le is at the ground level (“L” level), the determination unit35A determines that the bit information IB of that bit is “0”. When the switches Sa, Sb, and Sc or the connection pins Pd and Pe are set to the OFF state, since the voltage state on the wires La to Le is at the power supply VD level (“H” level), the determination unit35A determines that the bit information IB of that bit is “1”. Therefore, in the example ofFIG.8, when the 5-bit bit information IB is illustrated in the order of each voltage state on the wires La to Le, the 5-bit bit information IB is determined as “11001”. Note that the arrangement order of each bit is not limited to the example inFIG.8, and can be set freely. The content of the determination information610A including the bit information IB is individually set for each type (type of the relay device6) of the electromedical device1connected to the relay device6. In this manner, the determination unit35A performs determination using the electromedical device1together with the relay device6.

FIG.9illustrates an example of a truth table Tb′ used for determination according to Modified Example 1. Specifically, the truth table Tb′ illustrates an example of the output mode of the electric power Pout from the power supply device3A according to the content of the determination information610A (bit information IB).

The power supply device3A outputs the electric power Pout in an output mode that is corresponding to the type of the electromedical device1connected to the relay device6and is obtained by determination using the electromedical device1together with the relay device6(determination by the determination unit35A). In other words, the power supply device3A outputs the electric power Pout to the electromedical device1connected to each relay device6in a different output mode for each type of the relay device6(electromedical device1).

For example, as illustrated inFIG.9, the determination unit35A performs the following determinations based on the determined determination information610A (bit information IB). That is, the determination unit35A determines the connection status (connected state or non-connected state) of the relay device6to the power supply device3A, the connection status of the electromedical device1to the relay device6, and the type and number of electromedical devices1connected to the relay device6. The type of the electromedical device1includes, for example, the content of the output format, operation mode, and maximum output electric power described above.

A specific example of the output mode of the electric power Pout according to the content of the determination information610A (the content of each bit in the 5-bit bit information IB) is as follows, as illustrated in the truth table Tb′ ofFIG.9.FIG.9also illustrates whether or not output of the electric power Pout is enabled in each state.5th bit information=“0”: Connected state of relay device6(output of Pout enabled)5th bit information=“1”: Non-connected state of relay device6(Output of Pout disabled)4th and 3rd bit information=“00”: Coagulation mode (unipolar type)4th and 3rd bit information=“01”: Coagulation mode (bipolar type)4th and 3rd bit information=“10”: Incision mode (unipolar type)4th and 3rd bit information=“11”: Incision mode (bipolar type)2nd and 1st bit information=“00”: Connected state of two electromedical devices1a1and1a22nd and 1st bit information=“01”: Connected state of one electromedical device1a1(50 [W] mode)2nd and 1st bit information=“10”: Connected state of one electromedical device1a2(100 [W] mode)2nd and 1st bit information=“11”: Both are non-connected (Output of Pout disabled)

When it is determined that both of the two electromedical devices1a1and1a2are in a connected state, for example, if simultaneous connection of the two devices is not permitted, it may be set such that output of the electric power Pout is disabled.

Here, in Modified Example 1 as well, as in the embodiment, the determination unit35A does not perform determination in the output period of the electric power Pout from the power supply device3A. Similarly, when the determination unit35A detects that the content of the determination information610A (bit information IB) has changed in the output stop period of the electric power Pout from the power supply device3A, the determination unit35A performs determination based on the content of the determination information610A after the change after passing through the non-connected state of the relay device6or the electromedical device1.

Advantages and Effects

In this manner, in Modified Example 1, the determination unit35A performs determination using the electromedical device1together with the relay device6, so that the following advantages and effects are obtained. In other words, unlike the embodiment, in Modified Example 1, it is possible to cope with a plurality of types of electromedical devices1while suppressing the number of relay devices6to one. As a result, it is possible to improve the scalability with a simpler configuration for variations in the output mode of the electric power Pout according to the determination. As a result, Modified Example 1 can further improve convenience compared to the embodiment.

In Modified Example 1, as in the embodiment, when it is detected that the content of the determination information610A (bit information IB) has changed in the output stop period of the electric power Pout, the determination based on the content of the determination information610A after the change is performed only after passing through the non-connected state of the relay device6or the electromedical device1, so that the following advantages and effects are obtained. That is, since the determination based on the content of the determination information610A after the change is performed only when the relay device6or the electromedical device1is replaced, erroneous determination based on the change in the content due to other noise signals other than during energization, for example, can be avoided. As a result, in Modified Example 1 as well, as in the embodiment, the determination accuracy in the determination unit35is improved, and the convenience can be further improved.

Alternatively, in the electromedical device system5B, the power supply device3B is provided instead of the power supply device3A in the electromedical device system5A (FIG.8) of Modified Example 1, and the relay device6B is provided instead of the relay device6(relay device6d), and other configurations are the same.

In the power supply device3B, the determination unit35or the determination unit35A is omitted (not provided) in the power supply device3(FIG.2) or the power supply device3A (FIG.8), and other configurations are the same.

In the relay device6B, the determination unit35or the determination unit35A is further provided in the relay device6a(FIG.2) having the information storage unit61or the relay device6d(FIG.8) having the information storage unit61A, and other configurations are the same.

As described above, in Modified Example 2, the determination unit35or the determination unit35A is arranged in the relay device6B instead of in the power supply devices3and3A, respectively.

Also in Modified Example 2, basically, the same and/or similar effects as in the embodiment or Modified Example 1 can be obtained.
