SURGICAL TREATMENT DEVICE

摘要

Provided is a surgical treatment device that treats biological tissues by using ultrasonic vibration and high-frequency currents in combination, and in which sparks are prevented from occurring. The surgical treatment device includes a grasping member (33) having a restricting section (51) that is insulated from the electrode (58). When the grasping member (33) is closed toward the treatment section (32) after the receiver (66) has undergone abrasion exceeding a predetermined amount, the restricting section (51) comes into contact with the treatment section (32) before the electrode (58) does, thereby restricting the electrode (58) and the treatment section (32) from coming into contact with one another.
