The central control means 25 determines whether or not the confirmation operation has been performed, and does not erase the error display except when the operation has been performed. Further, when the content of the error is dealt with, the state monitoring means 25a detects that the error has been resolved and notifies the central control means 25, and the central control means 25 immediately displays an error display. No control to set on the normal display screen.
[0037]
Specifically, when an error occurs, a confirmation switch “OK” is displayed simultaneously with the error content displayed in the error display area 45 of the central control panel 39 as shown in FIG. This “OK” is displayed almost in synchronization with the corresponding error display.
Next, the operation will be described.
[0038]
When the centralized control panel 25 cannot control the centralized display panel 22, for example, when the communication cable is disconnected, the error display area 45 displays “The display panel display is incorrect. The display panel cannot be used.” At the same time, “OK” of the confirmation switch is displayed, and the display is not erased unless “OK” is pressed. That is, in this case, it also functions as an error display erasure switch for erasing the error display.
[0039]
In addition, when the error is resolved, in this case, after the communication cable is correctly connected and the “OK” switch is pressed, the normal screen is immediately returned to FIG. 4 to return from the error.
[0040]
The effect of this embodiment is as follows.
By confirming the error content and pressing the “OK” switch, the error that has occurred can be easily and reliably confirmed. In addition, it is possible to provide a control system capable of displaying an error promptly when an error is resolved.
[0041]
Next, a third embodiment of the present invention will be described.
An object of this embodiment is to provide a control system capable of displaying an error so that an operation screen and a status display screen other than the target device can be used even if a severe error occurs.

In FIG. 2, when the centralized control device 25 receives the detection of the occurrence of an error from the state monitoring means 25a, the centralized display panel 22 performs a display for notifying the occurrence of the error as in the first embodiment. At the same time, the central control panel 39 overwrites and displays the error content and the confirmation switch on the operation screen for displaying the operation switch of the device in which the error has occurred.
[0043]
That is, in the second embodiment, what is displayed in the error display area of the centralized control panel 39 is displayed on the operation screen for the device in which an error has occurred in this embodiment.
[0044]
For example, when an error occurs in the induction cautery device 32, an error display and “OK” of the confirmation switch are overwritten and displayed on the induction cautery device portion in the operation area 44 of the central control panel 39 as shown in FIG. Further, when an error occurs in the insufflator 33, as shown in FIG. 11, an error display and “OK” of the confirmation switch are overwritten on the insufflator part in the operation area 44.
[0045]
Next, the operation will be described.
In FIG. 10, the generated error is a serious error of the induction cautery device 32, and the area for displaying the error is overwritten and displayed only on the operation screen of the induction cautery device 32. Unless the error of the high frequency cautery device 32 is eliminated and the “OK” switch is pressed, the error display is not erased, and the operation screen of the high frequency cautery device 32 remains covered with the error display and the switch operation cannot be performed.
[0046]
In FIG. 11, the error that has occurred is a serious error of the pneumoperitoneum 33, and the area for displaying the error is overwritten and displayed only on the operation screen of the pneumoperitoneum 33. As long as the error of the insufflator 33 is resolved and the “OK” switch is not pressed, the error display is not erased, and the operation screen of the insufflator is still covered with the error display, and the switch cannot be operated. Both the switch operation and the status display screen of the operation screen other than the target device in which an error has occurred can be used in FIGS. 10 and 11.
