Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a medical system control apparatus for controlling various medical devices in a predetermined operation mode by a plurality of switches.

[0002]

2. Description of the Related Art In recent years, with the development of medical technology, various types of medical equipment have become abundant, and their functions have tended to be enhanced. Further, the medical equipment to be used is not limited to the electric knife, but various equipment such as an ultrasonic suction device or an endoscope is prepared. These may be used alone or in some cases as a combined medical system.

In an electric scalpel device, an ultrasonic scalpel device, a device combining them, or the like, a doctor holds a scalpel part (probe part) in his hand and operates a patient's treatment part. For this reason, the output of the device must be turned on and off with a foot, and a foot switch is often used in addition to a switch operated at hand. In particular, when used in combination with an endoscope, the operator operates the endoscope with both hands, and therefore, it becomes necessary to operate with the open leg for treatment under the observation of the endoscope.

Usually, a foot switch has a structure in which each switch is provided in the housing and the switch is closed by depressing a pedal provided on the outer surface of the housing.

Various types of foot switches are available, from a simple one using a micro switch to one using a non-contact switch (such as a photo coupler) so that a contact spark is not generated because the switch is used in a flammable atmosphere. There is one.

Since a plurality of switches are arranged side by side on the foot switch, it is necessary to visually check the feet and to search for the switch with the foot in order to properly step on the desired switch, which is troublesome.

[0007] Also, if you put it on the switch so that you do not search for the target switch with your foot, it may be dangerous because your weight suddenly turns on and the switch may turn on, so put your weight on your heel and put your foot on it. I was in an unnatural position such as floating up, and there was a physical burden.

Further, as a doctor, although he / she wants to concentrate on a portion to be treated for a patient, he / she has to pass the nerve to the foot switch, which often reduces his / her concentration.

On the other hand, it is necessary to provide a plurality of switches in order to support a multifunctional medical device that drives one device in a plurality of operation modes or a medical system including a plurality of devices.

Therefore, a plurality of foot switches (two, three, or more) are usually used for each operation mode or each device.

In the case of the scalpel device, the operation modes include an incision mode and a coagulation mode. To switch between these two modes, the foot switch has two
It will be provided in series.

[0012]

Not only the above-mentioned foot switch but also a device provided with a plurality of switches is convenient for dealing with multi-functionalization of equipment and operation of a plurality of equipment. If you line them up, you may operate an unintended switch. To prevent erroneous operation of the switch, it is effective to confirm the position of the switch, but it is troublesome. Especially in the case of a foot switch, it is necessary to confirm the foot level at each successive operation.

In the case of a foot switch, the operator may not be able to confirm his / her feet, such as when the operator is operating the endoscope under observation of an endoscope or when operating other equipment.

If the operator is skilled, it may be possible to perform a reliable operation without looking at the position of the switch, but it cannot be said that there is no erroneous operation. And it is difficult for a beginner to operate without looking at his / her feet.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a control device for a medical system which can prevent malfunction of the device and can operate the device reliably and with peace of mind.

[0016]

The present invention is directed to a medical system having a plurality of switches and capable of controlling the operation of a medical device for performing at least one of inspection, diagnosis and treatment by switching the switches. In the control device, the notification means for informing the operator of the operation mode of the medical device and the notification means for informing the operation mode corresponding to the operated switch of the plurality of switches by the operation of the switch A control means for controlling the operation of the medical device in a predetermined operation mode corresponding to the operated switch by maintaining the initially operated state of the switch for a predetermined time or operating the same switch again. have.

[0017]

With the above construction, when the switch is operated, the operation mode corresponding to the operated switch is notified by the notification means. At this stage, if the operator notices that he has not operated the target switch among the plurality of switches, he may cancel the operation of the first switch and operate the target switch again.

On the other hand, if it is announced that the target switch is being operated, the control means keeps the initially operated state of the switch for a predetermined time or operates the same switch again, so that the control means The operation of the device is controlled in a predetermined operation mode among a plurality of operation modes of the device.

Embodiments of the present invention will be described below with reference to the drawings. 1 to 6 relate to a first embodiment of the present invention, FIG. 1 is a schematic configuration diagram of a medical system, FIG. 2 is a signal waveform diagram in an operation mode, FIG. 3 is a signal waveform diagram in a confirmation operation mode, and FIG. FIG. 5 is a perspective view of the foot switch, FIG. 5 is a cross-sectional view of the foot switch, and FIG. 6 is a flowchart relating to the operation of the control circuit.

The medical system 1 of the first embodiment shown in FIG.
Is for controlling various medical devices in a predetermined operation mode by, for example, a foot switch having a plurality of switches. The medical system 1 includes an ultrasonic scalpel device 2 for excising an inspected portion by ultrasonic waves, an electric scalpel device 3 for excising an inspected portion by high frequency current, and the devices 2 and 3 in a predetermined operation mode. And a control device 5 including a foot switch (FWS) 4 for giving an instruction for control. The ultrasonic scalpel device 2 and the electric scalpel device 3 each have an ultrasonic probe and a high-frequency probe (not shown).

The control device 5 includes the foot switch 4
A foot switch (FSW) I / F circuit 6, a control circuit 7 as a control means, a display I / F circuit 8, a display panel 9 as a notification means, and a sound signal generation function as a notification means. Circuit 10, amplifier circuit 11 and speaker 12
And an I / F 13 for the apparatus.

The foot switch 4 is connected to a control circuit 7 via an I / F circuit 6 for a foot switch (FSW). The control circuit 7 is connected to a display panel 9 via a display I / F circuit 8. Further, the control circuit 7 is connected to the speaker 12 via the sound signal generation circuit 10 and the amplifier circuit 11. Further, the control circuit 7 controls the operations of the ultrasonic scalpel device 2 and the high-frequency scalpel device 3 via the device I / F circuit 13, respectively.

As shown in FIG. 1, the foot switch 4 comprises, for example, an electric knife cutting mode switch 4a, a coagulation mode switch 4b, and an ultrasonic knife cutting mode switch 4c. What is incision mode?
A high-frequency current is passed through the electric knife (probe) of the electric knife device 3 to drive the affected part so that it can be excised.
Further, the same mode is to drive the ultrasonic knife (probe) in the ultrasonic knife device 2 as well. Also,
In the coagulation mode, the output is weakened as compared with the incision mode, and the electric scalpel is driven to a state where hemostasis treatment can be performed on the bleeding site. The coagulation mode by the switch 4b may be an ultrasonic knife.

As shown in the external view of FIG. 4, the foot switch 4 is a triple switch. The number of switches may be two or four or more, and the number of switches may be increased or decreased according to the operation function.

The foot switch 4 has a substantially rectangular shape, and a footrest portion 13, which is an upper surface thereof, is provided with pedal portions 14, 15, 16 having a substantially circular shape. The pedal section 1
4, 15 and 16 are provided at positions slightly lower than the surface of the footrest portion 13. The pedal portion may be at the same position as the surface of the footrest portion 13.

Further, the foot switch 4 is provided with a total of four threshold portions 17 between the end portion of the footrest portion 13 and each of the pedal portions 14, 15 and 16. The four partition parts 17 are for determining the position where the foot is placed, and are provided so as to project to the surface of the footrest part 13 so as not to operate the adjacent switch by mistake. The partition portion 17 is provided so as not to step off the foot of the footrest portion 13.

As described above, since the surface of each pedal portion of the foot switch 4 is the same as or slightly lower than the surface of the footrest portion 13, it is not necessary to raise the heel or the toes during standby. That is, the feet can be kept in a comfortable state while waiting. Also, unless the pedal part is pushed inward, the switch does not switch, so it is difficult to make an erroneous operation. In other words, the structure is such that the switch does not turn on only by placing the foot on the surface of the housing. Furthermore, since the foot can be placed on the footrest portion, it is not necessary to work in an unnatural posture, and safe and stable work can be performed.

As shown in FIG. 5A, the foot switch 4 has pressing members 18 protruding from the bottoms of the pedal portions 14, 15 and 16, respectively. Also, each pedal unit 1
A plurality of elastic members 19 are interposed between the ends of 4, 15, 16 and the housing of the foot switch 4. Each pedal portion 14, 15, 16 is biased upward by the elastic member 19. In addition, the pedal portion 14
When is depressed, the pressing member 18 turns on the contact of the switch 4a provided inside the housing of the foot switch 4. The relationship between the pedal portions 15 and 16 and the switches 4b and 4c is the same as above. Each of the switches 4a, 4b, 4c is connected to the control circuit 7 via the foot switch I / F circuit 6.

The foot switch 4 is shown in FIG.
As shown in, the footrest portion 13 may be formed obliquely. The foot switch 4A shown in FIG.
Photocouplers 20 are arranged instead of the contact switches shown in FIG. The photo plastic 20 is
The shield plate 21 protruding from the bottom of the pedal portions 14, 15 and 16 is turned on / off by being inserted / removed.

In response to an instruction from the control circuit 7, the sound signal generation circuit 10 sounds the speaker 12 via the amplifier circuit 11 to notify the operation mode of the device 2 or 3 by sound.

A mode display signal output from the control circuit 7 is output to the display panel 8 via the display I / F, and the display panel 8 displays the operation mode.

The operation of this embodiment will be described below with reference to FIGS. 3, 5 and 6. The operator places the foot 22 on the footrest portion 11 of the foot switch 4 so as to straddle the pedal portion 14 (or 15, 16) as shown by the solid line in FIG. When the electric scalpel is to be operated in the incision mode, as shown by the broken line in FIG. 5A, the pulling toe is slightly stepped on the front and is stepped on the pedal portion 14, for example.

As shown in step S1 of FIG. 6, the switch 4a is turned on (closed), and its signal e is transmitted to the control circuit 7 via the foot switch I / F 6.

A signal indicating the incision mode is displayed on the panel 8 from the control circuit 7 through the display I / F 9 to inform the operator that the incision mode is selected, and the sound signal generation circuit 10 is also provided. Also tell the operating mode. At the same time, a signal indicating the incision mode is also output from the control circuit 7 to the audio signal generation circuit 10. And step S
2, the sound signal generation circuit 10 has a preset frequency,
The sound signal f1 shown in FIG. 2 (f) composed of timbre is amplified by the amplifier circuit 11 and the speaker 12 is driven to notify the operator by sound. At this time, the operator hears the sound, and if it is different from the selected operation mode, he / she may move his / her foot to the target pedal portion 14 and perform the same operation.

If it is correct, the electric scalpel can be operated in the incision mode by once depressing and then stepping on again. Alternatively, the stepped state may be maintained for a predetermined time. As shown in steps S3, S7, etc., in the control circuit 7, the switch 4a is OFF (open).
Or ON (closed).

When it is turned off in step S3, measurement of a timer T1 (not shown) is started in step S4.
After stopping the stepping on the pedal part, in step S5, as shown in FIG.
As shown in (f), the control circuit 7 stops the output of the sound f1 after a fixed time within a time TA described later.

In step S6, the control circuit 7 sets the time t1 from the time when the switch is turned off to the time when the pedal is stepped on again.
However, it is determined whether or not a predetermined time has passed. This time t1 is the time measured by the timer T1. Specifically, the interval t1 between the first depression of the pedal portion and the second depression of the pedal portion shown in FIG. 2 (e) must satisfy a preset relationship T0 <t1 <TA. It is determined. The time T0 is 0.1 second, for example, and is set to prevent malfunction due to chattering or the like. The predetermined time TA is a set time for determining whether to continue the operation after checking the operation mode, or to check once and stop the operation without reaching the output operation, and is set to, for example, about 1 to 2 seconds.

Then, if the pedal portion 14 of the foot switch is stepped down again in step S7 within the predetermined time TA (when TA> t1), the sound f2 shown in FIG. 2 (f) is output in step S8. . At this time, the sound f2 at a level different from that of the first operation is output from the speaker 12. That is, as shown in FIG. 2 (f), in the operation mode, the output sound is a sound f2 at a level different from that of the sound f1 so that the operator can distinguish the sound. There is. Both f1 and f2 have the same fundamental frequency (that is, pitch) and waveform (that is, timbre).

At the same time, the operation mode is set in step S9, and the drive instruction signal g is immediately output to the device 3 via the device I / F 13 as shown in FIG. Operated by.

In the operation mode, step S10
Then, when the switch 4a of the foot switch 4 is turned off, the driving of the electric knife is stopped in step S11, and the sound f2 is stopped in step S12. Then, the flow ends, and the setting of the control circuit 7 returns to the initial state. Note that the sound f2 may be stopped after a certain period of time has entered the operation mode.

On the other hand, in step S7, the switch 4a is turned off.
When the foot switch is stepped on again in step S14 after the predetermined time TA is exceeded in step S6 (when t1> TA) in F, the process proceeds to step S15.

In step S15, as shown in FIG. 3 (f), the operation mode confirmation sound f1 is output again for a certain period of time.

The sound signal f is as shown in FIG.
As shown in (f), the intermittent sound f1 and the continuous sound f2 at the time of the output operation are output to make a distinction. For example, when confirming the incision mode, the fundamental frequency of 1 KHz is interrupted at 10 Hz, and the sound of 1 KHz is continuously output during the output operation.

Even if the fundamental frequencies of the ultrasonic knife incision mode and the electric knife incision mode are the same, the timbre is changed so that the operator can identify. In the coagulation mode, the basic frequency is set to 1.5 KHz, and the pitch is changed depending on the mode. Of course, the tone may be the same and the tone color may be changed, or both may be changed at the same time.

Next, in step S16, the timer T2 starts measuring. The timers T1 and T2 may be the same timer, and may be reset if Yes in step S14.

If the switch 4a remains ON in step S17, and if the stepping time t2 measured by the timer T2 at the time of confirmation is t2> TC with respect to the preset TC in step S18, As shown in FIG. 3 (g),
The output operation is performed following the reconfirmation. That is, step S
The operations after 8 are started.

On the other hand, in step S17, the switch 4a remains off, and in step S19, t
When 2> TC, the flow ends. By this, the operator judges that the mode is different by reconfirmation,
When the switch 4a is turned off, erroneous operation can be prevented.

In step S14, the switch 4a is turned on.
In the case of FF, if t1> TB (> TA) in step S20, the operation mode is not entered. That is, the control circuit 7
So that the confirmation sound will be heard again with the next switch 4aON,
The sound signal generation circuit 10 will be controlled. Thus, the specified time TB is a setting for returning the control circuit 7 to the initial state unless the switch is operated a second time.

On the other hand, if the ON state is maintained in step S3, the measurement of the timer T1 is started in step S21. Further, in step S22, the control circuit 7 stops the output of the sound f1 after a fixed time. If the state in which the switch 4a is ON (time t1) exceeds the predetermined time TD in steps S23 and S24, the operation after step S8 is started. Note that the time t1 in step S24 shown by the broken line in FIG. 2 (e) is the duration of the ON state of the switch 4a, unlike the time t1 in step S6. If it is turned off before the predetermined time TD, the flow moves to step S6.

As described above, in order to perform the output operation,
You just have to step on the pedal twice. In addition to the output operation by stepping on the pedal twice, the output operation is performed by continuing the stepping operation for a predetermined time (TD).

In the present embodiment, the operation mode of the operated switch can be confirmed once with the audible sound, and if the switch is erroneously operated at that stage, the target switch can be operated again. In addition, in this embodiment, if the device is checked once and then is OK, the device operates in a predetermined mode when the switch is depressed again, so that the surgery can be performed with the line of sight concentrated on the affected area. Alternatively, in this embodiment, if the switch is depressed for a predetermined time, the operation mode is set after the confirmation sound is heard.

If the mode is displayed on the monitor for displaying an endoscopic image instead of the panel 9, the mode can be confirmed while observing the affected area.

In this embodiment, the operation mode can be confirmed by the ear, and it is not necessary to shift the line of sight to the feet. First, when the foot switch is stepped on, a sound is emitted at a predetermined frequency and tone color when the switch is operated, and the operation mode to be operated from now can be confirmed. Then, the operation is performed in the operation mode by once releasing and stepping on again.

As described above, in this embodiment, the operator can prevent the malfunction of the device without looking at his / her feet, and can operate the device reliably and with confidence.

Further, in the present embodiment, not only different sounds (frequency, tone color) are emitted according to each operation mode, but also the confirmation operation mode and the operation mode are provided even in the same mode. If the operator can surely confirm the state, he or she can depress the switch again or leave the switch depressed to enter the operation mode, and a continuous sound is output at different levels to immediately enter the operation state. On the other hand, after confirming again after the first operation, if the operator wants to enter the operation mode, if the operator depresses after a short interval, the same frequency and tone color sounds again, that is, the sound intermittently. You can operate the equipment after ringing and reconfirming.

Further, since the foot switch allows the foot to be placed on the foot switch with the weight normally applied, the physical load can be reduced.

Other than the switches, the operation is similar to the flowchart shown in FIG.

The medical device is not limited to the above-mentioned example, and any device such as a suction device and an air / water supply device can be used as long as its operation can be controlled.

As a modification of the first embodiment, if Yes in step S3 of FIG. 6, the operation may be performed as indicated by the broken line. That is, it is necessary to ensure that the operation mode is not entered unless the pedal is depressed twice. Other configurations and effects are similar to those of the first embodiment, and description thereof will be omitted.

FIG. 7 is a schematic configuration diagram of a medical system according to the second embodiment of the present invention.

The control device 5A of the present embodiment has a configuration in which a language / speech selection circuit 23 is added to the configuration of the control device 5 of the first embodiment. Further, the control device 5A has, instead of the sound signal generation circuit 10, a voice synthesis circuit 24 capable of producing artificial human voice. Then, the voice synthesizing circuit 24 outputs the voice signal in the language selected by the language / voice selecting circuit 23. Other configurations and operations similar to those of the first embodiment are designated by the same reference numerals and description thereof will be omitted.

In the above-mentioned configuration, the operation is almost the same as that of the first embodiment, except that the voice f1 at the time of confirming the operation mode is the synthesized human voice. For example, f1 becomes "ultrasonic scalpel incision mode", "coagulation mode", etc., which makes it easy for the operator to identify by ear.

First, by operating the pedal for the first time, the operator is informed of the synthesized voice of the person, for example, by repeating the voice twice, for example, "the electric knife incision mode." At this time, if the operator confirms the selected operation mode and it is different, for example, if it is the “coagulation mode”, the adjacent pedal portion 14
Move to and do the same. If it is correct, the output in the incision mode is supplied to the electric scalpel by once depressing and then stepping on again.

The waveform f during the operation of the device 2 or 3
2 may be the same as in the first embodiment, or may be a synthetic voice such as "dissected" or "coagulated".

It is also possible to register various voice colors such as a male voice and a female voice in the voice synthesizing circuit 24 and select a voiced voice by the language / voice selecting circuit 23. In addition, register the utterance content in a language other than Japanese,
It is also possible to select. The language is, for example, English,
German, French, and Western languages.

In this embodiment, the function of the operated switch and the operating state of the device are output in a language that is most understandable to the operator, so that it is easy to confirm. Other configurations and effects are similar to those of the first embodiment, and description thereof will be omitted.

Next, a third embodiment of the present invention will be described. The third embodiment has the same structure as that of the first or second embodiment except that the switches 4a to 4c of the foot switch 4 are two-stage switches. The foot switch of the third embodiment becomes the operation mode confirmation state by depressing in one step, and becomes the operation state by depressing in one more step.

In the present embodiment, when the confirmation and the operation output have already been completed once, and the foot position remains the same, and when the user wants to output again, he does not wait for the confirmation, but depresses to the second step at once to immediately perform the output operation. I can do it. Other configurations and effects are similar to those of the first embodiment, and description thereof will be omitted.

FIG. 8 is a schematic configuration diagram of a main part of a control device according to the fourth embodiment of the present invention.

The control device of the present embodiment has a voice synthesis circuit 25 capable of arbitrarily registering the type of voice and voice content, instead of the voice synthesis circuit 24 of the second embodiment.
The voice synthesizing circuit 25 is composed of a voice synthesizing section 26 for outputting a voice signal, and a card reader 27 for reading the record information of the recording medium 26 on the card. For example, if a rewritable magneto-optical card is used as the recording medium 28, the magneto-optical card reader 27 reads the recorded information on the card 28. The voice synthesizer 26 uses the magneto-optical card reader 2
An audio signal is output according to the signal output by 7. As a result, in this embodiment, the content and language of the message relating to the mode and the like can be registered, the message can be newly rewritten, and the specification can be changed. Also, it is easy to add / change / delete messages and the like. Furthermore, the utterance content and the voice quality can be changed according to the user's preference. As described above, in this embodiment, the utterance content can be updated in accordance with the addition / correction of the function. The card reader 27 is an IC card reader, a magnetic card reader, or the like, and may be adapted to the recording medium. Alternatively, as another data input device, a communication circuit or the like may be provided to transmit data from the outside.

Although the present invention has been described with respect to the embodiment of the foot switch, the invention is not limited to this. For example, the present invention can be applied to a switch such as a handpiece for an electric scalpel that is provided with a plurality of switches and that is manually operated.

In each of the above embodiments, the control device is provided with operation mode selection means for switching the control contents of the control circuit 7, the foot switch 4 is a single switch, and the operation selected by the operation mode selection means is executed. It can also be configured to. Also in this configuration, the display of the operation mode and the identification by the sound are effective.

Further, the suction pump 60 housed in the cart 51 has a suction tank 62 through a first suction pipe 61.
Is in communication with. The suction tank 62 includes a second suction pipe 63.
Through a suction pipe line (not shown) of the handpiece 55. A pinch valve 64 that opens / closes the conduit is arranged in the middle of the suction pipe 63. The probe 5
Suction is made from a tip opening (4) not shown.

The foot switch 50 is composed of a plurality of pedal units, for example, three units 65 to 67 as shown in FIG. Pedal unit 6
A switch 5 controls the ultrasonic oscillation of the probe 54. The pedal unit 66 is a switch that controls driving of the water feed pump 56 of the drive device 52. Further, the pedal unit 67 includes the pinch valve 64 of the drive device 52.
It controls the opening and closing of.

The pedal unit 65 is the connector 6
Pedal unit 66 and pedal unit 67
Are electrically connected to the pedal unit 66 via the connection connector 69. The pedal unit 66 is electrically connected to the cable 53. The pedal parts 75, 76, 77 of each dull unit and its internal structure are
The configuration is the same as that shown in FIG. 5, and description thereof will be omitted.

Further, each pedal unit is provided with a partition portion 47 at its end. This partition 47
Is formed in a quarter-cylindrical shape, and when each unit is combined, it has the same shape as the partition portion 17 shown in FIG.

As shown in FIGS. 11A and 11B, in the connection connectors 68 and 69, electric signals from the pedal units 65 and 67 are sent to the pedal unit 66, and in FIGS.

The pedal units 65 and 67 have holes communicating with each other so as to be attached to the pedal unit 66, and are attached by a fixing member 71.

In the above structure, when the pedal portion 76 of the pedal unit 66 is stepped on, an electric signal is sent to the driving device 52 via the cable 53, the probe 54 oscillates ultrasonically, and the foot is released from the pedal portion 69a. Ultrasonic oscillation stops.

When the ultrasonic oscillation of the probe 54 is stopped, when the pedal portion 75 of the pedal unit 65 is stepped on, an electric signal is sent to the pedal unit 66 via the connector 68, and the water pump 56 of the drive unit 52 is activated. To drive.
Then, while the cooling water of the water supply bottle 59 is supplied to the probe 54, the water supply stops when the foot is released from the pedal portion 75.

Further, the drive device 52 has two kinds of drive modes, that is, an interlocking suction mode for interlocking with the ultrasonic oscillation of the probe 54 and suctioning, and a continuous suction mode for always sucking regardless of the ultrasonic oscillation. When the suction mode is selected as the interlocking suction mode and the ultrasonic oscillation of the probe 54 is stopped, when the pedal portion 77 of the pedal unit 67 is stepped on, an electric signal is sent to the pedal unit 66 via the connection connector 69, The pinch valve 64 of the drive device 52 opens. This allows suction from the probe 54, and when the foot is released from the pedal 77, the pinch valve 54 closes and suction stops.

Since the external shapes of the connectors 68 and 69 are the same, they can be interchanged. Further, since the pedal units 65 and 67 are assembled to the pedal unit 66 by the fixing member 71, they can be removed.

As described above, according to the present embodiment, when the left and right arrangement of the pedal units 65 and 67 is not preferable for the operator, the connection connectors 68 and 69 are exchanged so that the left and right arrangements are changed. become. Therefore, the arrangement of the pedal unit can be changed according to the necessity of the pedal in the field of surgery or the preference and accustomation of the operator.

In addition, depending on the field of surgery, an unnecessary pedal unit can be removed, and mistakes and anxiety such as erroneous operation due to the unnecessary pedal unit can be eliminated, and the safety can be improved and the space under the feet can be cleared. it can.

Other than that, the same components and operations as those of the first embodiment are designated by the same reference numerals and the description thereof will be omitted.

Next, a modified example of the foot switch is shown in FIGS. 13 and 14, and this modified example will be described. FIG.
Is an exploded / assembled view of the foot switch, and FIG. 14 is a side view of the function switch of the foot switch. The same components and operations as those of the foot switch 50 will be designated by the same reference numerals and description thereof will be omitted.

The foot switch 80 of the modification is composed of pedal units 66, 85, 87 and a fixing member 71. The connection units 68 (or 69) are integrally attached to the pedal units 85 and 87.

The pedal units 85 and 87 are electrically connected to the pedal unit 66 by being attached via connecting connectors 68 and 69. The pedal units 85 and 87 are each provided with a switch 82 for selecting a function. The switch 82 is
As shown in FIG. 14, water supply (IRR), suction (SU)
C) and stop (OFF) can be selected.

With the above-described structure, the functions of the left and right pedal units 85 and 87 can be electrically switched by switching the function selectable switch 82. Further, since the pedal units 85 and 87 are mechanically assembled to the pedal unit 66, they can be removed.

Therefore, according to this embodiment, the pedal units 85 and 87 can be operated by switching the pedal switch 82.
You can change the placement of and don't have to completely disassemble it. When switching, the fixing member 71 may be slightly loosened and switched. The reason why the switch 82 is provided on the side surface to be assembled is to prevent the switch from being switched due to some adjustment.

When the switch 82 is provided on the upper surface of the unit, it is safe to use a lock switch having a structure that does not switch unless the direction is once changed or lifted. With this configuration, there is no need to disassemble each time the arrangement is changed.
