Description

  The present invention relates to an ultrasonic surgical system for treating a living tissue by ultrasonic vibration.

  Conventionally, various surgical apparatuses using ultrasonic waves, such as an ultrasonic scalpel apparatus and an ultrasonic trocar apparatus described in JP-A-9-38098, have been proposed as applied techniques of ultrasonic vibration.

  In such an ultrasonic surgical apparatus, a handpiece having a treatment section for treating a living tissue is provided with an ultrasonic vibrator for generating ultrasonic vibration, and an ultrasonic vibration from the ultrasonic vibrator is applied to the treatment section. It has a built-in probe for transmission.

Each piece can be operated individually.

  Next, referring to FIG. 3, the hand switch 4 and the foot switch 5, the extension unit 6 to which the connectors of the hand switch 4 and the foot switch 5 are connected, and the device main body 2 to which the extension unit 6 is connected will be described. A circuit block diagram will be described. First, the inside of the apparatus main body 2 will be described.

  The device main body 2 includes a switch detection circuit 31 that detects a signal from the foot switch 5 or the hand switch 4 via the extension unit 6, a control unit 32 that outputs a control signal based on the signal of the switch detection circuit 31, An oscillator circuit 33 for driving the handpiece in accordance with a control signal of the control unit 32, and a connector connection unit 13 for connecting the connection connector 12 of the extension unit 6; The handpiece has a connector connection portion 9 to which the handpiece connectors 8a, 8b, 8c of the handpiece are selectively connected. Note that the foot switch connector 22 of the foot switch 5 is directly connected to the device main body 2, and one of the two pedal switches A and B of the foot switch 5 is pressed by the switch detection circuit 31 of the device main body 2. The received signal may be received.

  The hand switch 4 includes, for example, the two switches A and B described above. The hand switch 4 has a wiring connecting the contact 34a of the switch A and the contact 34b of the switch B, a wiring of a contact 35a of the switch A, and a wiring of the switch B. And a hand switch connector 21 having a wiring for a contact 35b.

  When the switch A of the hand switch 4 is depressed, the contact 34a and the contact 35a of the switch A are electrically connected, and are electrically connected to the extension unit 6 via the hand switch connector 21. On the other hand, when the switch B is pressed, the contact 34b and the contact 35b of the switch B conduct, and like the switch A, conduct with the extension unit 6 via the hand switch connector 21.

  The foot switch 5 includes, for example, the two pedal switches A and B described above, and connects the contact 36a of the pedal switch A and the contact 36b of the pedal switch B similarly to the hand switch 4. The contact 37a of the pedal switch A and the contact 37b of the pedal switch B are connected.

  The expansion unit 6 includes, as the generation means, for example, one of the OR gates OR1 of the OR circuit 38 and an analog switch SW1 that opens and closes with the output of the OR gate OR1, and the other of the OR circuit 38 opens and closes with the outputs of the other OR gate OR2 and the OR gate OR2. And a hand switch connector section 28 for connecting the hand switch connector 21 of the hand switch 4 and a foot for connecting the foot switch connector 22 of the foot switch 5 as described above. It has a switch connector section 29 and a connection connector 12 as connection means for connecting to the apparatus main body 2.

  Of the three wires of the hand switch connector portion 28 of the extension unit 6, the first wire is connected to a + V for setting the H level and a foot switch connector portion 29 for connecting the foot switch connector 22. The third wiring is connected to the OR gate OR1, and the third wiring is connected to the OR gate OR2.

  Similarly, in the foot switch connector section 29, the first wiring is connected to the + V for setting to H level and the hand switch connector section 28 for connecting the foot switch connector 22, and the second wiring is connected to the OR gate OR1. , And the third wiring is connected to the OR gate OR2.

  The output terminal of the OR gate OR1 is connected to the analog switch SW1, and similarly, the output terminal of the OR gate OR2 is connected to the analog switch SW2. The connection between the OR gate OR1 and the analog switch SW1 and the connection between the OR gate OR2 and the analog switch SW2 are connected to the ground via the resistor R1 or the resistor R2. Therefore, when the A or B switch of the hand switch 4 or the foot switch 5 is not pressed, the output terminal of the OR gate OR1 or the OR gate OR2 is at the L level.

  The contact a of the analog switch SW1 is connected to A of the connector 12, and the contact b is connected to COM of the connector 12. On the other hand, the contact a of the analog switch SW2 is connected to B of the connector 12, and the contact b is connected to COM of the connector 12.

  When the hand switch 4 or the foot switch 5 is depressed, one of the hand switch 4 and the foot switch 5 becomes conductive, and the hand switch 4 or the foot switch 5 is connected via the hand switch connector 21 of the hand switch 4 or the foot switch connector 22 of the foot switch 5. Either one of the two OR gates OR1 and OR2 becomes active, and either one of the analog switches SW1 and SW2 is turned on, and the device main body 2 is connected to the connection connector 12 via A and COM or B and COM. To the switch detection circuit 31 of FIG. More specifically, when the switch A of the hand switch 4 is pressed, the contact 34a and the contact 35a of the switch A conduct, and the level becomes H level by + V in the extension unit. As a result, the OR gate OR1 becomes conductive, and the analog switch SW1 turns from off to on. When the analog switch SW1 is turned on, conduction is established between A and COM of the connection connector 12, and a closed circuit is formed by the switch A of the hand switch 4, the OR gate OR1 of the extension unit 6, the analog switch SW1, and the A and COM of the connection connector 12. Thus, the switch detection circuit 31 can detect that the switch A of the hand switch 4 is pressed. The extension unit 6 may have a priority set to either the hand switch 4 or the foot switch 5, or may have a function of giving priority to the first push.

  Using the ultrasonic surgical apparatus 1A thus configured, the scissors-type handpiece 3A as the first handpiece is brought into contact with the treatment portion 16a of the scissors-type handpiece, for example. The handpiece 3A is controlled.

  For example, when the A or B switch of the hand switch 4 is pressed, the operation signal of the hand switch 4 is transmitted to the extension unit 6. The output of the extension unit 6 is transmitted to the switch detection circuit 31 of the apparatus main body 2 to detect which switch has been pressed, and the control section 32 controls ON / OFF of the oscillation circuit 33 based on the detected signal. Done. The output of the oscillation circuit 33 is transmitted to, for example, the scissors-type handpiece 3A via the handpiece connector 8a, and can turn on / off the ultrasonic output.

  As a result, the hand switch 4 can be used even in the ultrasonic surgical apparatus 1A in which only the existing foot switch 5 can be used, and the usability is improved.

  By the way, since the hand switch 4 described with reference to FIG. 3 is electrically connected to the apparatus main body 2, the treatment section 16a of the scissors-type handpiece 3A is brought into contact with the treatment target site of the patient's living tissue to treat the living tissue. In such a case, there is a possibility that conduction to the living tissue may occur through the hand switch 4.

  Therefore, a circuit for electrically separating the hand switch 41 and the foot switch 42 is provided as shown in FIG. First, the hand switch 41 and the foot switch 42 will be described.

  The hand switch 41 includes, for example, two switches A and B in the same manner as in FIG. 3, and a wire connecting a contact 43 a of the switch A and a contact 43 b of the switch B, a wire of a contact 44 a of the switch A, And a hand switch connector 45 provided with the wiring of the contact 44b of the switch B.

  The foot switch 42 has a configuration similar to that of the hand switch 41, and includes, for example, two pedal switches A and B. Inside the contact switch 46a of the pedal switch A and the pedal switch B, similarly to the hand switch 41. And a foot switch connector 49 provided with a wiring connecting the contact 46b of the pedal switch A, a wiring of the contact 47a of the pedal switch A, and a wiring of the contact 47b of the pedal switch B.

  The extension unit 43 includes, for example, two photocouplers 51a and 51b that electrically separate and insulate the hand switch 41 and the apparatus main body 2 to transmit a signal, a power supply 52 for the photocouplers 51a and 51b, and a power supply current for the photocouplers 51a and 51b. A hand switch connector section 54 for connecting the hand switch connector 45 of the hand switch 41 and a foot switch connector section 55 for connecting the foot switch connector 49 of the foot switch 42. And a connection connector 56 as connection means for connecting to the apparatus main body 2.

  The wiring of the hand switch connector section 54 is connected to the power supply 52, and one end thereof is connected to the light emitting diode D1 of the photocoupler 51a via a resistor R3, and from the light emitting diode D1 to the hand switch connector section 54. Wired back. Similarly, the other end is connected to the light emitting diode D2 of the photocoupler 51b via the resistor R4, and is wired so as to return from the light emitting diode D2 to the hand switch connector unit 54.

  The output side of the phototransistor Tr1 of the photocoupler 51a that receives the light emitted from the light emitting diode D1 is wired to a connection connector 56 connected to the device main body 2 and a foot switch connector 55 connected to the foot switch connector 49 of the foot switch 42. Similarly, the output side of the phototransistor Tr2 for receiving the light emitted from the light emitting diode D2 of the photocoupler 51b is also wired to the connection connector 56 and the foot switch connector 55.

  The scissors-type handpiece 3A is controlled in a state where the treatment section 16a of the scissors-type handpiece 3A is brought into contact with the treatment target site of the living tissue using the ultrasonic surgical apparatus configured as described above.

  For example, by depressing the A or B switch of the hand switch 41, the photocoupler 51a or 51b is operated and transmitted to the switch detection circuit 31 in the apparatus main body 2 to output an ultrasonic wave. The same operation is performed when the A or B pedal switch of the foot switch 42 is depressed. Accordingly, since the photocouplers 51a and 51b are insulated from each other, they are not conducted to the living tissue via the hand switch 41, and the electrical safety is maintained.

  With the above configuration, the hand switch 41 and the apparatus main body 2 can be electrically separated from each other, and the hand switch 41 can be used more safely and electrically than the circuit described with reference to FIG.
