摘要： A forceps-type treatment instrument includes an end effector including a pair of clamps. In one of the clamps, a swinger is extended along an extending axis and swings relative to a supporting section around a swing axis extended along a direction intersecting with the extending axis and intersecting with an open and close direction of the clamp. A regulating section regulates movement of the swinger in the direction along the swing axis in at least two portions separated from each other in a direction along the extending axis, and thereby prevents rotation of the swinger around a rotation axis along the open and close direction.

摘要： A treatment instrument includes a grasping piece that is openable and closable to a treatment portion, and includes an electrode member. An electrode inclination surface facing a side on which the treating portion is located is provided on an outer surface of the electrode member of the grasping piece, and the electrode inclination surface extends from an inner side to an outer side in a width direction so as to be inclined in a direction away from the treatment portion.

摘要： An ultrasonic treatment instrument includes a vibration transmitting member transmitting ultrasonic vibration toward a first gripper and formed as one piece, and a second gripper movable between a spaced position where the second gripper is spaced apart from the first gripper and a closed position where the second gripper is put in close to the first gripper. The ultrasonic treatment instrument includes an interlocking actuator increasing, by moving the first gripper in interlock with a movement of the second gripper to the spaced position, a spacing distance between the first gripper and the second gripper in accordance with a movement of the first gripper.
