The foot switch 24 has two pedals, an incision pedal 31 and a coagulation pedal 32, as shown in FIG. 3. As will be described later, the incision pedal 31 and the coagulation pedal 32 are formed of a photo interrupter. , The same two first and second incision detection circuits and the first and second coagulation detection circuits are connected. Further, the foot switch 24 includes a foot switch plug 33,
The foot switch plug 33 is connected to the high-frequency ablation power supply 1 via a foot switch connector 41 installed on the back panel of the high-frequency ablation power supply 1 shown in FIG.

As shown in FIG. 1, the outputs of the two first incision detection circuits 2 and 3 of the incision pedal 31 of the foot switch 24 and the first output of the coagulation pedal 32 are shown.
The outputs of the coagulation detection circuit 4 and the second coagulation detection circuit 5 are output to the control circuit 8 of the high-frequency ablation power supply device 1 via the AND circuits 6 and 7. That is, the foot switch 24
In the case where the two first incision detection circuits 2 and the second incision detection circuit 3 of the incision pedal 31 are not output at the same time, AN

No signal is output. as a result,
Even if one of the two detection circuits fails in the incision pedal 31 and the coagulation pedal 32, no high-frequency current is output, and the operator can safely and reliably recognize the failure of the foot switch 24. It has become.

The high-frequency ablation power supply device 1 includes the control circuit 8
A front panel 9 for performing various settings such as a current value of a high-frequency current; and an EEPROM 1 serving as a nonvolatile memory for storing set values set on the front panel 9 under the control of the control circuit 8.
0, an oscillation circuit 11 composed of a crystal oscillator and a drive circuit, which can control the oscillation / stop of a high-frequency pulse, a power supply circuit 12 operating as a variable power supply, and a resonance for inputting power supplied from the power supply circuit 12 An amplification circuit 13 including a circuit and various abnormality detection circuits, and a waveform generation circuit 14 for generating a signal for controlling the amplification circuit 13 based on a high-frequency pulse from the oscillation circuit 11 are provided. The power supply device 1 is connected to an output connector described later.

Here, the oscillation circuit 11 oscillates a high-frequency pulse only when outputting the high-frequency current when it is detected that the foot switch 24 is depressed, under the control of the control circuit 8. It is controlled so that the oscillation of the high-frequency pulse is stopped except when the current is output.

On the front panel 9, as shown in FIG. 5, an output connector 51 to which the amplifying circuit 13 is connected, a power switch 52 for turning on / off the power of the apparatus, and a type of the cut-out waveform are selected. Mode selection switch 5 for
3, an incision output adjustment switch 54 for adjusting the incision output, a coagulation output adjustment switch 55 for adjusting the coagulation output, and an instruction to call the previous set value after turning on the power switch 52 and a setting change after the setting is completed. A standby switch 56 having a function of instructing output and prohibition of output, an incision mode indicator 57 indicating the type of incision waveform currently selected,
An incision output indicator 58 composed of, for example, 7-segment LEDs indicating the current incision output and a 7-segment LED coagulation output indicator 59 indicating, for example, a current coagulation output are provided.

Next, the operation of the high-frequency ablation power supply device 1 configured as described above will be described.

The operator operates the power switch 52 on the front panel 9.
6, the control circuit 8 first determines whether or not the standby switch 56 of the front panel 9 has been pressed in step S1 as shown in FIG. If it is determined in step S1 that the standby switch 56 has not been pressed,
In step S2, it is determined whether any one of the incision mode selection switch 53, the incision output adjustment switch 54, and the coagulation output adjustment switch 55 (hereinafter, referred to as switches) is pressed.

If it is determined in step S2 that the switches have not been pressed, the process returns to step S1, but if it is determined in step S2 that the switches have been pressed, the set values set by the operator are displayed in the incision mode in step S3. Light 57, incision output indicator 58, and coagulation output indicator 59
, And stored in the internal memory, and then proceeds to step S6.

The setting of the operator by the switches in step S2 is, for example, the incision and coagulation output setting values by the incision output adjustment switch 54 and the coagulation output adjustment switch 55. Is 1
It can be set in 0W increments. In addition, the setting of the incision mode by the incision mode selection switch 53 can be set to, for example, five modes of predetermined “incision”, “mixing 1”, “mixing 2”, “mixing 3”, and “mixing 4”. is there.

On the other hand, when the control circuit 8 determines that the standby switch 56 has been pressed in step S1, the control circuit 8 proceeds to step S4 to call the set value stored in the EEPROM 10, and in step S5 sets the set value read from the EEPROM 10 into the incision mode. Indicator light 57, total incision output indicator 5
8 and displayed on the coagulation output indicator 59 and stored in an internal memory, and then proceeds to step S6.

Here, regarding the display on the incision mode indicator 57, the incision output indicator 58, and the coagulation output indicator 59 in step S4, the incision mode indicator 57 displays in order until the mode called from the incision is reached. Incision output display 5
8. On the coagulation output indicator 59, the mode and the output set value are changed and displayed in order until the value reaches the value called out from 5W. As a result, the operator can easily identify whether there is a failure in each of the segments of the incision output indicator 58 and the coagulation output indicator 59 composed of the 7-segment LEDs, and the set values are normally displayed. Can be surely recognized.

In step S6, when the operator depresses the incision pedal 31 or the coagulation pedal 32 of the foot switch 24, the incision pedal 31 is detected via the AND circuit 6 of the first incision detection circuit 2 and the second incision detection circuit 3. A signal or a detection signal via the AND circuit 7 of the first coagulation detection circuit 4 and the second coagulation detection circuit 5 of the coagulation pedal 32 is transmitted to the control circuit 8.

Here, for example, the operator operates the foot switch 2
Assuming that the incision pedal 31 is depressed, the AND circuit 6 causes the control circuit 8 to make a determination shown in Table 1 below based on a combination of two detection signals from the first incision detection circuit 2 and the second incision detection circuit 3. become.

[0027]

[Table 1] That is, as shown in Table 1, when the ON signal is transmitted from both the first incision detection circuit 2 and the second incision detection circuit 3, the control circuit 8 determines in step S6 that the foot switch 2
It is determined that the incision pedal 31 of No. 4 has been turned ON.

In step S7, the control circuit 8 executes the waveform generation circuit according to the contents displayed on the incision mode indicator lamp 57 and the incision output indicator 58, that is, the set values at the incision stored in the internal memory. 14, while controlling the power supply circuit 12 and the oscillation circuit 11 to supply a high-frequency current to the output connector 51, and the contents displayed on the EEPROM 10 by the incision mode indicator 57, the incision output indicator 58, and the coagulation output indicator 59; That is, the setting value stored in the internal memory is written and the setting value is updated.

After the processing in step S7, the control circuit 8 controls the oscillation circuit 11 to start the oscillation of the crystal oscillator in step S8, and the waveform generation circuit 14 A control signal for the amplifier circuit 13 is created based on a waveform selection signal that is a control signal from the control circuit 8. On the other hand, in step S8, the power supply circuit 12 determines the power supply voltage to be supplied to the amplification circuit 13 based on the control signal from the control circuit 8, and the amplification circuit 13 is supplied with the power supplied from the power supply circuit 12 and the power supply from the waveform generation circuit 14. The high frequency power is supplied to the output connector 51 by the control signal.

In steps S6 to S8, the same operation is performed, for example, when the operator steps on the coagulation pedal 32. That is, for example, when the operator depresses the coagulation pedal 32 of the foot switch 24, the control circuit 8 outputs two signals from the first coagulation detection circuit 4 and the second coagulation detection circuit 5.
Based on the combination of the two detection signals, the control circuit 8 makes the determination shown in Table 2 below, and proceeds to step S7.

[0031]

[Table 2] When it is determined that the foot switch 24 is depressed, the above-described processing is performed. Then, it is determined whether or not the foot switch 24 is turned off in step S9. Then, the high frequency current is continuously supplied, and if it is determined to be OFF, the process returns to step S6.

Here, in step S6, the foot switch 2
The case where it is determined that step 4 is not depressed will be described. The control of the control circuit 8 is performed from step S6 to step S1.
The process proceeds to 0, and it is determined whether switches are pressed. The determination in step S10 is the same as that in step 2 described above. If it is determined that the switches have not been pressed, the process returns to step S6. If it is determined that the switches have been pressed, the operator adjusts the settings in step S11. The adjusted value is displayed on the incision mode indicator 57, the incision output indicator 58, and the coagulation output indicator 59, stored in the internal memory, and returns to step S6.

In this way, each time the foot switch 24 is depressed, the set value stored in the EEPROM 10 is updated. At the next use, the operator turns on the power switch 52 and then presses the standby switch 56, whereby The control circuit 8 recalls the set value at the time of the previous output stored in the EEPROM 10, and the incision mode indicator 57 sequentially displays the incision output indicator 58 and the coagulation output indicator 59 until the mode called from the incision is set. The mode and the output set value are changed and displayed in order from 5 W to the called value. Thereafter, when the operator steps on, for example, the incision pedal 31 of the foot switch 24, high-frequency output is performed in accordance with the values displayed on the incision mode indicator 56 and the incision output indicator 57 by the same operation as described above.

In step S7 of the above processing, when the control circuit 8 determines that the incision pedal 31 or the coagulation pedal 32 from the foot switch 24 has been turned on,
The setting value stored in the internal memory is written in the EEPROM 10 and the setting value is updated.
Read the contents of M10 and read the contents of internal memory and EEP
The contents before the update of the ROM 10 may be compared, and processing may be performed so that the EEPROM 10 is updated only when the set values are different. By performing such processing, the EEPR
The number of times of writing to the OM 10 can be reduced.

As described above, according to the present embodiment, each time the foot switch 24 is depressed, the set value stored in the EEPROM 10 is updated. EEP unrelated and meaningless set values
Only the set values necessary for the treatment can be reliably stored in the EEPROM 10 without storing them in the ROM 10.

Since there is no need to back up the set values when the power is turned off, the set values can be securely stored without the need for a backup battery and without complicating the apparatus.

Further, in the foot switch 24,
If the two first incision detection circuits 2 and the second incision detection circuit 3 of the incision pedal 31 are not output at the same time, no detection signal is output to the control circuit 8 by the AND circuit 6, and similarly, the first coagulation of the coagulation pedal 32 is performed. Detection circuit 4, second coagulation detection circuit 5
Since the detection signal is not output to the control circuit 8 by the AND circuit 7 unless the detection signals are simultaneously output, the high-frequency current is output even if one of the two detection circuits fails in the incision pedal 31 and the coagulation pedal 32. Therefore, the operator can safely and reliably recognize the failure of the foot switch 24.

The indications on the incision mode indicator 57, the incision output indicator 58 and the coagulation output indicator 59 are as follows.
The incision mode indicator 57 and the coagulation output indicator 5 are sequentially displayed on the incision mode indicator 57 until the mode is called from the incision.
9 is displayed by changing the mode and the output set value in order until the value reaches the value called from 5 W, so that each of the segments of the incision output indicator 58 and the coagulation output indicator 59 consisting of 7 segment LEDs has a failure. The operator can easily identify whether or not the setting value is displayed, and can surely recognize whether or not the set value is normally displayed. Even in the case of failure, it can be easily determined.

Further, the control circuit 8 includes the foot switch 2
Since the crystal oscillator in the oscillation circuit 11 is oscillated by the signal from the device 4, unnecessary power is not consumed, electrical noise when high frequency is not output can be reduced, and unnecessary electromagnetic radiation can be prevented. It is possible to prevent the display from being affected on a peripheral device, for example, a living body monitoring device such as an electrocardiograph, which is disposed in the periphery.

FIG. 7 is a configuration diagram showing the configuration of the high-frequency ablation power supply device according to the second embodiment of the present invention.

Since the second embodiment is almost the same as the first embodiment, only different points will be described, and the same components will be denoted by the same reference numerals and description thereof will be omitted.

As shown in FIG. 7, in the present embodiment, the foot switch 24a has no AND circuit, and the first incision detection circuit 2 and the second incision detection circuit 3 of the incision pedal 31.
And the respective detection signals of the first coagulation detection circuit 4 and the second coagulation detection circuit 5 of the coagulation pedal 32 are directly transmitted to the control circuit 8a.

The other structure is the same as that of the first embodiment.

In this embodiment, when the operator makes settings in the same manner as in the first embodiment, and depresses, for example, the incision pedal 31 of the foot switch 24a, the first incision detection circuit 2, the second incision detection circuit 3 transmits a signal to the control circuit 8a. Here, the control circuit 8a makes the determinations in Tables 3 and 4 below so that the ON / OFF control can be performed even if one of the detection circuits fails due to the combination of the two control signals.

[0045]

[Table 3]

[Table 4] In addition, the warning of the foot switch abnormality in Table 4 is performed by blinking the indicator lamp on the front panel 9.

In other words, the control circuit 8a monitors the state of the first incision detection circuit 2 and the second incision detection circuit 3 so that one of the first and second incision detection circuits 3 fails. In other words, by monitoring the state B and the state C in Table 3, for example, the incision pedal 31 of the foot switch 24a is depressed, and as shown in Table 4, the state B and the state C are monitored.
Alternatively, even when the state changes from the state C to the state A or the state D, it can be determined that one of the first incision detection circuit 2 and the second incision detection circuit 3 has failed.

Normally, both the ON signals are transmitted from the first incision detection circuit 2 and the second incision detection circuit 3, and the control circuit 8
"a" determines that the foot switch 24a is turned on. Then, the control circuit 8 a transmits signals to the waveform generation circuit 14, the power supply circuit 12, and the oscillation circuit 11 according to the contents displayed on the incision mode indicator 57 and the incision output indicator 58.
Further, the control circuit 8a transmits the contents displayed on the incision mode indicator lamp 57 and the incision output indicator 58 to the EEPROM 10 and stores them. The same applies to the coagulation pedal 32. Both the first coagulation detection circuit 4 and the second coagulation detection circuit 5 of the coagulation pedal 32 transmit ON signals, and the control circuit 8a determines that the foot switch 24a is ON.
Then, according to the contents displayed on the coagulation output indicator 59, the control circuit 8a executes the waveform generation circuit 14, the power supply circuit 1
2. Transmit a signal to the oscillation circuit 11. Further, the control circuit 8a transmits the content displayed on the coagulation output indicator 59 to the EEPROM 10 and stores it.

When one of the two detection circuits fails, a warning is displayed and a high-frequency current is output. However, the output may be stopped as shown in Table 5 below.

[0049]

[Table 5] Other operations are the same as those of the first embodiment.

As described above, in the present embodiment, in addition to the effects of the first embodiment, the control circuit 8a includes, for example, the first incision detection circuit 2 and the second incision detection circuit 3 in the incision pedal 31 of the foot switch 24a. Can be monitored, so that it can be determined whether one of the first incision detection circuit 2 and the second incision detection circuit 3 has failed. As a result, correct output can always be performed safely, and the operator can be notified of a failure by a warning display. The same applies to the coagulation pedal 32.

In this embodiment, the values of the incision mode indicator 57 and the incision output indicator 58 are stored during incision output, and only the values of the coagulation output indicator 59 are stored during coagulation output. In the first embodiment, the contents displayed on the incision mode indicator 57, the incision output indicator 58, and the coagulation output indicator 59, that is, the set values stored in the internal memory are written. On the other hand, it is possible to reduce the number of times the EEPROM 10 is used and to store only meaningful set values.
