Abstract
A surgical operating apparatus includes an ultrasonic treatment section which performs ultrasonic treatment on a living tissue, and a high-frequency treatment section which performs high-frequency treatment on the living tissue, and includes a narrow width part which is provided on at least one of mutually opposed surfaces of a first electrode portion of a first grasping member and a second electrode portion of a second grasping member. The narrow width part is configured to be disposed at a position where the second grasping member does not easily suffer a stress due to ultrasonic vibration when the living tissue is grasped between the second grasping member and the first grasping member, and to make a distance between the mutually opposed surfaces of the first electrode portion and the second electrode portion narrower than a distance at other positions.
