Next, a description is given of an endoscope surgery system according to a second embodiment of the present invention with reference to FIGS. 11 and 12.
Referring to FIG. 11, a system controller 220 comprises: the components of the system controller 20 shown in FIG. 2 according to the first embodiment; and a control unit 246 having operation log recording controlling means 251, error log recording controlling means 252, reading means 253, VTR play controlling means 254, and display control means 255.
When the above medical device is operated, the operation log recording controlling means 251 records the operation contents as an operation log file to the hard disk 48.
When the error is caused in the above medical device, the error log recording controlling means 252 records error contents as an error log file to the hard disk 48.
According to the second embodiment, the VTR 17 has means for recording, to the video tape, time for starting the recording and time for ending the recording.
Thus, with the above-mentioned structure, the operation log recording controlling means 251, the error log recording controlling means 252, and the hard disk 48 are state change recording means which records a state change of the medical device to the log file together with the causing time, when the state of the medical device changes. The VTR 17 is recording means which records the endoscope image.
When the VTR 17 is played, the reading means 253 reads start time and end time of the recording to the video tape (recording medium) of the VTR 17. The recording means 253 reads the recording start time which is recorded to the video tape (recording medium).
Therefore, the reading means 253 is recording-start-time recording means which records the recording start time to the video tape (recording medium).
The VTR play controlling means 254 plays the VTR 17 based on the data from the control signal receiving unit 41.
The VTR play controlling means 254 is play and display means which plays and displays the video image recorded to the VTR 17 (recording means) on the monitor 18 or the display panel 22.
The display control means 255 counts the play time of the VTR 17, calculates the time together with the start time, and displays, on the monitor 18 or the display panel 22, information recorded to the operation log file or the error log file in the hard disk 48 simultaneously with the generated image on the VTR 17.
Therefore, the display control means 255 comprises play counting means, calculating means, and log contents display means.
The play counting means of the display control means 255 counts the play time of the VTR play controlling means 254 (play and display means).
The calculating means of the display control means 255 calculates the actual play time by adding the recording start time read by the reading means 253 and the play counting time by the play counting means.
The log contents display means of the display control-means 255 compares the actual play time calculated by the calculating means with the occurrence time of the log file, and displays the log contents at the occurrence time simultaneous with the actual play time.
Conventionally, the operation log and the error log are usually recorded as text information. The operation log and the error log are mainly used by, a service person for maintenance. When the operation log and the error log have the text information, the performed operation and the error index are known. However, the occurrence timing and situation of the performed operation and error are not known.
In addition to the service person, the operator reviews the operation state or reports the operation state to another doctor. However, the occurrence timing and situation are not known.
To solve the difficult operation situations, according to the second embodiment, the operation log, the error log, and the endoscope image are displayed together to easily be viewed.
The medical devices are directly operated, thereby transmitting the information to the system controller 220.
When the medical devices are operated via the operation panel 21, the information is transmitted to the system controller 220.
The operation log recording controlling means 251 in the control unit 246 records the information as the operation log file into the hard disk 48 in the system controller 220.
When the error is caused in the medical devices, similarly to the operation log file, the error information is transmitted to the system controller 220.
The error log recording controlling means 252 in the control unit 246 records the information as the error log file to the hard disk 48 in the system controller 220.
The endoscope image during the operation is generally recorded to the VTR 17. Upon starting to record the data of the VTR 17, the start time and the end time are recorded and are stored in a video tape as a recording medium of the VTR 17.
Recently, the information may be recorded to recording devices such as the hard disk or a DVD device, in place of the VTR.
The above-stored video tape is played and then a screen 260 shown in FIG. 12 is displayed on the monitor 18 or the display panel 22.
