  The scissor-type handpiece 3A, hook-type handpiece 3C and trocar-type handpiece 3D have their handpiece plugs 14a, 14c, 14d connected to the output ports 54a, 54b, 54c, and are selectively connected. You can use two handpieces. Further, it is possible to cope with the case where the device incorporating the built-in type hand switch 20 described in the first embodiment is detachably connected to the extension unit 53.

  On the front panel 61 of the apparatus main body 52, a power switch 62 and a display panel 63 indicating an operation state, and a hand switch connector 64 to which the external hand switch 55 can be detachably connected, as in the first embodiment. Is provided. A foot switch connector 56b (see FIG. 5) to which a foot switch plug 56a of the foot switch 56 can be detachably connected is provided on a rear panel (not shown) of the apparatus main body 52. The output port 52a of the device main body 52 is connected to the input port 53a of the expansion unit 53 by a connection cord 65 (see FIG. 5). The signal is supplied through the output port 52a, the connection cord 65, and the input port 53.

  The extension unit 53 has the same function as the hand switch connector 63 of the device main body 52, and connectors 71, 72, 73 to which the hand switch 55 can be detachably connected, and the output ports 54a, 54b, Selection switches 74, 75, 76 capable of manually selecting one of the ports 54c, a speaker 77 for notifying the selected handpiece and hand switch by sound, and a remote switch plug 57a of the remote switch 57 are detachably attached. A remote switch connector 78 (see FIG. 5) that can be freely connected is provided.

  In the present embodiment, the output ports 54a, 54b, 54c of the extension unit 53 selected by the selection means provided on the extension unit 53 based on the operation signal of the external hand switch 55 or the remote switch 57 are An output switching means for selectively switching the output (ON / OFF) of the driving signal from the driving means provided in the apparatus main body 52 is provided.

Next, a circuit configuration of the ultrasonic operation system according to the second embodiment will be described with reference to FIG.
The circuit configuration of the device main body 52 has the same configuration and function as the device main body 2 described with reference to FIG. 3, and mainly includes a drive circuit 81, a SW detection circuit 82, a display panel 83, and a control circuit 84. Is done.

  The circuit configuration of the extension unit 53 includes a relay 85 for switching the output ports 54a, 54b, and 54c of the extension unit 53 to connect signal lines, and operating the built-in hand switch 20, the external hand switch 55, or the remote switch 57. It mainly comprises a control circuit 86 for controlling the relay 85 based on a signal.

Although not shown, the control circuit 86 has a latch or a memory. When an output port is once selected, the selected output port is stored until the output port is selected again.
In the figure, the scissors-type handpiece 3A, the scissors-type handpiece 3B having the built-in type hand switch 20, the external hand switch 55, and the remote switch 57 are connected to the extension unit 53. I have.

  Each of the built-in hand switch 20, the external hand switch 55, and the remote switch 57 can select any one of the output ports 54a, 54b, and 54c by being pressed. When an operation signal due to a pressing operation is input to the control circuit 86 of the extension connector 53, the control circuit 86 controls the relay 85 to switch to the selected output port, and the SW detection circuit of the main body 52. 82.

  The hand switch such as the built-in hand switch 20 or the external hand switch 55 can use only the selected hand piece, and the same switch has two functions of an output on / off function and a selection function. It is complicated. Therefore, by simultaneously pressing the A and B switches of the hand switch, a signal for selecting an output port is configured to be an operation signal for outputting a drive signal (ON / OFF) when pressed separately. . More specifically, by simultaneously depressing the A and B switches of the built-in hand switch 20 or the external hand switch 55, it is recognized as a signal for selecting one of the output ports 54a, 54b, 54c, When the switches are separately pressed, if the switch is a switch corresponding to the output port that is already selected, the switch is transmitted as an operation signal for outputting (on / off) a drive signal.

  When any one of the output ports 54a, 54b, 54c is selected, which output port is selected is displayed on the display panel 8 under the control of the control circuit 86. As a means for confirming which output port is actually selected when the user is in a hard-to-see position, depending on the type or sound of the sound, for example, once the output port 54a is selected, one sound is output, and the output port 45b is output. When selected, a sound such as twice sound is generated by the control circuit 86 and the speaker 77 is driven to produce sound.

In the same manner as in the first embodiment, for example, the treatment unit 13b of the scissors-type handpiece 3B having the built-in type hand switch 20 is applied to the treatment target site of the living tissue by using the ultrasonic operation system 50 configured as described above. Ultrasonic treatment is performed in the state of contact.
Then, the switch of the built-in hand switch 20, the external hand switch 55 or the remote switch 57 is pressed to select an output port.

Here, a process of selecting an output port by the built-in hand switch 20 or the external hand switch 55 will be described with reference to FIG.
For example, when the switch A (SW-A) and the switch B (SW-B) of the built-in hand switch 20 are simultaneously pressed, the signal is input to the control circuit 86 of the extension unit 53 and the switch A (SW-A) Then, it is detected that the switch B (SW-B) has been pressed simultaneously (step S1), and selection control for selecting the output port 54a is performed (step S2).
In this selection control, a signal for selecting the output port 54a is transmitted to the SW detection circuit 82 of the apparatus main body 52, and the relay 85 is controlled to switch according to the selected output port 54a.
The scissors type handpiece 3B and the built-in hand switch 20 currently used are displayed on the display panel 83 under the control of the control circuit 34 of the apparatus main body 52, and the control circuit 86 of the extension unit 53 controls the display. The selected output port 54a is notified by the sound of the speaker 77 (step S3).

  Also, without simultaneously pressing down the switches A (SW-A) and B (SW-B) of the hand switch, pressing down the selection switch (selection SW) 74 of the front panel 71 provided in the extension unit 53. Then, the signal is input to the control circuit 86 of the extension unit 53, the pressing operation of the selection switch (selection SW) 74 is detected (step S4), and the selection control of the output port 54a is similarly performed (step S2). Notification of the selected output port 54a (Step S3) is performed.

  Further, when the selection switch corresponding to the output port 54a of the remote switch (remote SW) 57 is pressed, similarly to the selection switch 74 of the extension unit 53, the pressing operation of the selection switch is detected (step S5), and so on. The output port selection control (step S2) and the notification of the selected output port (step S3) are performed.

On the other hand, when the switch A (SW-A) or the switch B (SW-B) of the built-in type hand switch 20 is individually pressed, the signal is input to the control circuit 86 of the extension unit 53 and the switch A (SW-A). ) Or switch B (SW-B) is individually pressed (step S6 or step S7), and the pressed switch A (SW-A) or switch B (SW-B) is already selected. If the switch corresponds to the output port 54a (step S8), the signal of the pressed switch A (SW-A) or switch B (SW-B) is transmitted to the apparatus main body 52 (step S9).
When the output port 54a is selected, a drive signal from the drive circuit 81 provided in the apparatus main body 52 is transmitted to the scissors-type handpiece 3B via the selected output port 54a, and performs an ultrasonic treatment. be able to.

  As a result, the operability can be improved and the operator can concentrate on the operation by selecting the handpiece desired to be used by the operator performing the operation. Further, when a handpiece is selected by operating the built-in type hand switch 20, the function of turning on and off the output and the function of selecting the output port can be separated without increasing the number of hand switch lines. Operability is good. Further, even if the output port switching result cannot be viewed on the display panel 63 of the apparatus main body 52, the operability can be improved because it is possible to confirm which output port was actually selected by phonetics. I do.

By the way, the hand switch used in such an ultrasonic operation system has internal wiring as shown in FIG.
The hand switch 101 shown in FIG. 7A includes a switch A and a switch B for output on and output off.
On the other hand, a hand switch 102 shown in FIG. 7B is different from the hand switch 101 in that a select switch S is added in addition to two output switches of a switch A and a switch B. When the switch S is pressed, the switches A and B are simultaneously turned on. Thus, when the switch A and the switch B are pressed at the same time, the switch functions as an output port selection switch.

  In addition, since these hand switches 101 and 102 have two functions of an output on / off function and a selection function with the same one hand switch, depending on the handpiece, output on and output off are set to the built-in type hand switch 20. In some cases, only the output port is selected by another switch such as a foot switch. Therefore, as shown in FIG. 7C, it is effective to use a hand switch 103 provided with only the selection switch S.

  The ultrasonic operation system according to the present invention is not limited to the above-described embodiment, but can be variously modified without departing from the gist of the present invention.
