PROBLEM TO BE SOLVED: To enable selective cutting, coagulation, and fastening of tissue in surgical treatment, by rotating a clamp arm with respect to an end effector by reciprocating motion of an actuation member and clamping the tissue between the clamp arm and the end effector. SOLUTION: A lever part 193 is placed on the opposite side of a wave guide 180 and an end effector 180' and functionally fit with a drive part 194 of a reciprocating actuation member 170. The reciprocating motion of the actuation member 170 with respect to an outer tubular sheath 160 and the waveguide 180 performs the rotating motion of the clamp arm 190 with respect to the end effector 180'. part 194. A clamp arm includes a clamp arm tissue pad 192 and is attached to cooperate with the end effector 180'. The rotating motion of the clamp arm 190 is determined by bringing the position of the clamp pad in a parallel relation to the end effector 180' and in contact with the same. |
