Abstract: A treatment tool includes: an elongated shaft; a probe that protrudes from a distal end of the shaft; a movable jaw that is mounted in a rotatable manner; and a swing arm that is mounted on the movable jaw. The swing arm is capable of gripping living tissue with the probe and swinging with respect to the movable jaw. The movable jaw includes a first regulating surface that can contact a proximal end portion of the swing arm to regulate swinging of the swing arm in one direction, and a second regulating surface that can contact another region in the proximal end portion of the swing arm to regulate swinging of the swing arm in another direction.

Abstract: A treatment tool includes: a shaft; a gripper member that protrudes from a distal end of the shaft; a movable jaw that is provided on a distal end side of the shaft and is openable and closable with respect to the gripper member; and a swinging member mounted on the movable jaw. The swinging member is capable of swinging about a rotation axis with respect to the movable jaw to grip the living tissue between the swinging member and the gripper member. The swinging member includes first and second contact surfaces. The first contact surface can regulate swinging of the swinging member in a first direction when contacting a first regulating surface of the movable jaw. The second contact surface can regulate swinging of the swinging member in a second direction when contacting a second regulating surface of the movable jaw.
