Abstract: A treatment instrument includes a first treatment portion including a first member with a first contact surface and a second member with a second contact surface; a movement mechanism to switch between a closed position where the first and second contact surfaces are close to each other and an open position where the first and second contact surfaces are separated each other; and a second treatment portion juxtaposed to the first treatment portion. A distal end of the second treatment portion is located at a distal side in the longitudinal axis than a distal end of the first treatment portion on the closed position.

Abstract: A treatment tool includes a sheath, a first grasping member, a second grasping member and a swing member. The first grasping member protrudes from a distal portion of the sheath. The second grasping member is rotatably provided to the sheath so that a first angle, which is an angle formed with the first grasping member, changes. The swing member is provided to the second grasping member so as to swing and so that a second angle, which is an angle formed with the second grasping member, changes. When the second angle is at its maximum, there is a first angle at which the first grasping member and the swing member do not contact each other.

Abstract: 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.

Abstract: A treatment instrument includes: a first treatment section which includes a first body including a first contact surface and a second body including a second contact surface; a movement mechanism which is configured to switch between a closed position in which the first contact surface and the second contact surface are close to each other, and an opened position in which the first contact surface and the second contact surface are distant from each other; and a second treatment section which is disposed on a distal side along the longitudinal axis with respect to the first treatment section when the first contact surface and the second contact surface are located in the closed position, and which is configured to apply energy to the living tissue to incise or separate the living tissue.
