Alternatively, it may be realized by a dedicated circuit such as FPGA (Field Programmable Gate Array) or ASIC (Application Specific Integrated Circuit).

Next, the operation of the endoscope system 1 having such a configuration will be described.
First, the operation of the electric scalpel device 3 will be described.
2 to 4 are timing charts showing operation examples of the electric scalpel device 3. FIG.

In each of FIGS. 2 to 4 , the upper part shows the states of switches that are turned on and off in conjunction with the operation of the operation unit 31 . More specifically, the switch is turned on while the operation unit 31 is being operated (while the electric scalpel is instructed to output a high-frequency current), and while the operation unit 31 is released ( The switch shall be turned off while the electric scalpel is not instructed to output high-frequency current. In the drawing, the state in which the switch is on is indicated by an "H" level signal, and the state in which the switch is off is indicated by an "L" level signal. The middle part shows the signal state of the enable signal output from the enable signal output unit 32 . The lower part shows the output state of the high-frequency current from the electric knife. The state in which the high-frequency current is being output is indicated by an "H" level signal, and the state in which the high-frequency current is not being output is indicated by an "L" level signal. .

The example shown in FIG. 2 is an example in which the operation on the operation unit 31 is continuously performed.
In this case, as shown in FIG. 2, when the switch is switched from off (“L”) to on (“H”) in conjunction with the start of the operation of the operation unit 31, the switch is switched with a slight delay. , the signal state of the enable signal output from the enable signal output unit 32 is switched from the "L" level to the "H" level. Further, after a slight delay from the switching of the switch, the electric scalpel starts outputting a high-frequency current.

After that, when the switch is switched from on ("H") to off ("L") in conjunction with releasing the operation of the operation unit 31, the output of the high-frequency current from the electric scalpel stops according to the switching of the switch. Also, with a slight delay from the switching of the switch, the signal state of the enable signal output from the enable signal output section 32 is switched from "H" level to "L" level.

The example shown in FIG. 3 is an example in which the operation on the operation unit 31 is repeatedly performed.
In this case, as shown in FIG. 3, after the operation performed on the operation unit 31 is canceled, it is performed again (the switch that was on ("H") is turned off ("L")). and then turn it on (“H”) again), the period during which the operation on the operation unit 31 is canceled (the period during which the switch is turned off (“L”)) is less than the predetermined period. Only in certain cases, the signal state of the enable signal output from the enable signal output unit 32 is prevented from being switched (remained at "H" level). On the other hand, the output state of the high-frequency current from the electric knife is switched according to the series of operations described above. That is, when the operation performed on the operation unit 31 is released (when the switch is switched from on (“H”) to off (“L”)), the output of the high-frequency current is stopped accordingly. After that, when the operation unit 31 is operated again (when the switch is switched from off (“L”) to on (“H”) again), the high-frequency current starts to be output accordingly.

By the operation of the electric scalpel device 3 as shown in FIGS. 2 and 3, when the electric scalpel device 3 (electric scalpel) is in any state immediately before, during, or immediately after outputting high-frequency current, The signal state of the enable signal output from the enable signal output unit 32 becomes the first signal state ("H" level), and the electric scalpel device 3 (electric scalpel) is in the state immediately before, during, and immediately after outputting the high-frequency current. In neither state, the signal state of the enable signal output from the enable signal output section 32 becomes the second signal state (“L” level).

The example shown in FIG. 4 is an example in which the operation of the enable signal output section 32 is stopped.
In this case, as shown in FIG. 4, the signal state of the enable signal output from the enable signal output section 32 remains at the "L" level regardless of the operation on the operation section 31. FIG. Note that this example is also an example in which an operation similar to the operation on the operation unit 31 illustrated in FIG. 3 is performed.

Next, the operation of the endoscope video processor 4 will be explained.
In the endoscope video processor 4, when the enable signal detection unit 42 detects the enable signal input from the electric scalpel device 3, the touch panel 43 and the communication unit 44 perform the following operations.

In the touch panel 43 , the touch panel control section 431 controls the touch detection operation on the touch panel 43 based on the signal state of the enable signal detected by the enable signal detection section 42 . More specifically, the touch panel control unit 431 controls to stop the touch detection operation on the touch panel 43 when the signal state of the enable signal is the first signal state. This control is performed, for example, by stopping the operation of the touch panel operation detection unit 432 . Further, the touch panel control unit 431 changes the signal state of the enable signal from the second signal state to the first signal state within a predetermined period after the signal state of the enable signal is switched from the first signal state to the second signal state. is not switched to the signal state of , the touch panel 43 is controlled to restart the touch detection operation. This control is performed, for example, by restarting the operation of the touch panel operation detection unit 432 .

In the communication unit 44 , the data transmission/reception control unit 441 controls data transmission/reception operations with the peripheral device 6 based on the signal state of the enable signal detected by the enable signal detection unit 42 . More specifically, the data transmission/reception control unit 441 controls to stop the data transmission/reception operation with the peripheral device 6 when the signal state of the enable signal is the first signal state. This control is performed, for example, by stopping the operation of the data transmission/reception unit 442 . However, if the data transmission/reception unit 442 is transmitting data to the peripheral device 6 or receiving data from the peripheral device 6 when performing the control, the control is performed after the transmission or reception is completed. I do. Further, the data transmission/reception control unit 441 changes the signal state of the enable signal from the second signal state to the second signal state within a predetermined period after the signal state of the enable signal is switched from the first signal state to the second signal state. If the signal state is not changed to 1, control is performed so that the data transmission/reception operation with the peripheral device 6 is restarted. This control is performed, for example, by restarting the operation of the data transmission/reception unit 442 .

As described above, according to the endoscope system 1 according to the first embodiment, when the signal state of the enable signal input from the electric scalpel device 3 to the endoscope video processor 4 is the first signal state That is, when the electric scalpel device 3 (electric scalpel) is in any state immediately before, during, or immediately after outputting a high-frequency current, the endoscope video processor 4 performs a touch detection operation on the touch panel 43, and , the data transmission/reception operation with the peripheral device 6 stops. Therefore, it is possible to prevent the touch panel 43 from malfunctioning or the communication failure between the endoscope video processor 4 and the peripheral device 6 due to the influence of the noise generated when the electric scalpel device 3 (electric scalpel) outputs a high-frequency current. be able to.

Further, only when the signal state of the enable signal is switched from the first signal state to the second signal state and is not switched again to the first signal state within a predetermined period, the touch detection operation on the touch panel 43, and , the data transmission/reception operation with the peripheral device 6 is resumed, it is possible to avoid such an undesirable situation as the operation that those operations are immediately stopped after the resumption.

In addition, in the endoscope system 1 according to the first embodiment, the enable signal detection unit 42, the touch panel control unit 431, and the data transmission/reception control unit 441 provided inside the endoscope video processor 4 may It may be configured to be provided outside the mirror video processor 4 .

In the electric scalpel device 3, the operating unit 121 generates a press signal of a first signal level (e.g., “L” level) indicating no pressing operation when there is no pressing operation on the operating unit 121 by the user. When there is a pressing operation on the portion 121, a pressing signal of a second signal level (for example, "H" level) indicating presence of pressing operation is generated. Here, the case where the operation unit 121 is pressed by the user means that the operation unit 121 is pressed by the user, and the case that the operation unit 121 is not pressed by the user means that the user operates This is when the part 121 is not pressed.

If the data transmission/reception unit 1332 is transmitting/receiving data at this time, the communication with the external device by the data transmission/reception unit 1332 may be stopped when the transmission/reception ends. Further, the data transmission/reception control unit 1331 causes the data transmission/reception unit 1332 to perform communication with an external device at the timing when the second predetermined time has elapsed from the timing at which the depression signal is switched from the second signal level to the first signal level. let it resume. However, the depression signal changes from the first signal level to the second signal level during the period from the timing when the depression signal is switched from the second signal level to the first signal level until the second predetermined time elapses. , the communication with the external device by the data transmission/reception unit 1332 is continued to be stopped.

It controls detection of a change in capacitance of the touch panel 141 or output of a detection signal by the detection unit 1412 .

As described above, according to the medical system 11 according to the second embodiment, while the operation unit 121 of the electric scalpel device 12 is being pressed by the user (while the high-frequency current output instruction is being issued), The operation of the touch panel operation detection unit 1322 in the tablet terminal 13 (detection of change in capacitance of the touch panel 132 or output of detection signal) stops, and the operation of the touch panel operation detection unit 1412 in the endoscope video processor 14 (touch panel 141 detection of changes in capacitance or output of detection signals) stops. Also, the operation of the data transmission/reception unit 1332 in the tablet terminal 13 (communication with an external device) is stopped. Therefore, the touch panel 132 of the tablet terminal 13 and the touch panel 141 of the endoscope video processor 14 malfunction due to the influence of the noise generated when the electric scalpel device 12 outputs the high-frequency current, or the tablet terminal 13 and the endoscope video processor 14 malfunction. It is possible to prevent the occurrence of communication failure between the tablet terminal 13 and the peripheral device 15 .

In addition, when the operation unit 121 that has been pressed by the user is released and then immediately pressed, the above-described stop of the operation is continued, so that the operation stops immediately after the operation is resumed. Unfavorable situations can be avoided as such operations.

The medical system 11 according to the second embodiment may be modified as follows.
For example, the electric scalpel device 12 further includes a status signal generation unit that generates a status signal with a different signal level depending on whether the high-frequency current output unit 122 is outputting high-frequency current, and the signal output unit 123 A status signal generated by the status signal generation unit may be output to the tablet terminal 13 instead of the depression signal generated by the operation unit 121 . In this case, the status signal is an example of the specific signal mentioned above.

In such a case, in the tablet terminal 13, the signal detection unit 131 receives the status signal output from the electric scalpel device 12 (signal output unit 123) and controls the touch panel 132, the peripheral device control unit 133, and the endoscope video processor. 14.

In the touch panel 132 , the touch panel control section 1321 controls detection of a change in capacitance of the touch panel 132 or output of a detection signal by the touch panel operation detection section 1322 based on the status signal output from the signal detection section 131 . For example, only when the status signal is at a signal level indicating that high-frequency current is being output, the touch panel operation detection unit 1322 stops detecting changes in the capacitance of the touch panel 132 or outputting the detection signal.

In the peripheral device control unit 133 , the data transmission/reception control unit 1331 controls communication with the external device by the data transmission/reception unit 1332 based on the status signal output from the signal detection unit 131 . For example, only when the status signal is at a signal level indicating that the high-frequency current is being output, communication with the external device by the data transmission/reception unit 1332 is stopped.

In the endoscope video processor 14, the touch panel control unit 1411 of the touch panel 141, like the touch panel control unit 1321 of the tablet terminal 13, operates the touch panel based on the status signal output from the tablet terminal 13 (signal detection unit 131). It controls detection of a change in capacitance of the touch panel 141 or output of a detection signal by the detection unit 1412 .

According to such a modification, only when the electric scalpel device 12 is outputting a high-frequency current, the touch panel operation detection unit 1322 in the tablet terminal 13 detects a change in the capacitance of the touch panel 132 or outputs a detection signal. When the output stops, the touch panel operation detection unit 1412 in the endoscope video processor 14 stops detecting the change in capacitance of the touch panel 141 or outputting the detection signal. Also, the communication with the external device by the data transmission/reception unit 1332 in the tablet terminal 13 is stopped. Therefore, even with such a modified example, it is possible to prevent malfunction of the touch panels 132 and 141 and communication failure due to the influence of noise generated when the electric scalpel device 12 outputs a high-frequency current.

Also, for example, the electric scalpel device 12 generates an enable signal with a different signal level depending on whether the high-frequency current output unit 122 is in a state immediately before, during, or immediately after outputting the high-frequency current. An enable signal generation unit may be further provided, and the signal output unit 123 may output the enable signal generated by the enable signal generation unit to the tablet terminal 13 instead of the press signal generated by the operation unit 121 . In this case, the enable signal is an example of the specific signal described above.

In such a case, in the tablet terminal 13, the signal detection unit 131 receives the enable signal output from the electric scalpel device 12 (signal output unit 123) and controls the touch panel 132, the peripheral device control unit 133, and the endoscope video processor. 14.

In the touch panel 132 , the touch panel control unit 1321 controls detection of a change in capacitance of the touch panel 132 or output of a detection signal by the touch panel operation detection unit 1322 based on the enable signal output from the signal detection unit 131 . For example, when the enable signal is at a first signal level (for example, “H” level) indicating that the high-frequency current is in a state immediately before output, during output, or immediately after output, the touch panel operation detection unit 1322 , stop the detection of the change in the capacitance of the touch panel 132 or the output of the detection signal. Also, from the timing when the enable signal is switched from the first signal level to the second signal level (for example, "L" level) indicating that the high-frequency current is neither immediately before, during, or immediately after the output of the high-frequency current. If the enable signal does not change before the predetermined time elapses, the touch panel operation detection unit 1322 resumes detecting a change in capacitance of the touch panel 132 or outputting a detection signal.

In the peripheral device control unit 133 , the data transmission/reception control unit 1331 controls communication with the external device by the data transmission/reception unit 1332 based on the enable signal output from the signal detection unit 131 . For example, when the enable signal is at the first signal level, communication with the external device by the data transmitter/receiver 1332 is stopped. Further, when the enable signal does not change during a period from the timing when the enable signal is switched from the first signal level to the second signal level until the predetermined time elapses, the data transmission/reception unit 1332 and the external device to resume communication.

In the endoscope video processor 14, the touch panel control unit 1411 of the touch panel 141, like the touch panel control unit 1321 of the tablet terminal 13, operates the touch panel based on the enable signal output from the tablet terminal 13 (signal detection unit 131). It controls detection of a change in capacitance of the touch panel 141 or output of a detection signal by the detection unit 1412 .

According to such a modification, when the electric scalpel device 12 is in any state immediately before outputting, during outputting, or immediately after outputting the high-frequency current, the touch panel operation detection unit 1322 of the tablet terminal 13 detects the touch panel 132. Detection of a change in capacitance or output of a detection signal stops, and detection of a change in capacitance of the touch panel 141 or output of a detection signal by the touch panel operation detection unit 1412 in the endoscope video processor 14 stops. Also, the communication with the external device by the data transmission/reception unit 1332 in the tablet terminal 13 is stopped. Therefore, even with such a modified example, it is possible to prevent malfunction of the touch panels 132 and 141 and communication failure due to the influence of noise generated when the electric scalpel device 12 outputs a high-frequency current.

Further, in the second embodiment, the touch panel device is configured as the tablet terminal 13, but it is not limited to the tablet terminal, and may be configured as other portable information terminal devices such as smart phones.
