The ground wire 57 can impart ultrasonic vibration and a bipolar high-frequency electrode to the tip of the blade 21 through the entire path in which the vibrator 13, the booster 14, and the blade 21 are integrated. .

The electrical signal wiring structure of the ultrasonic surgical device is shown in FIG. 6 , as shown in FIG. 6 , the electrical signal wiring of the ultrasonic surgical device is except for that the high-frequency signal line 55 is omitted from the electrical signal wiring of the complex surgical device The rest of the signal transduction structure is the same.

As described above, the present invention transmits an ultrasonic output and a high-frequency output through a common ground line 57 connected to the vibrator 13 in the output signal line of the combined surgical instrument, and also different outputs output by two switch buttons Since a signal can be transmitted to the output generating device 30 through one signal line, the signal wiring layout can be designed more effectively.
