Abstract: 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.

Abstract: A grasping treatment instrument includes a sheath, a first grasping piece provided at a distal end of the sheath, a second grasping piece and a movable member. The second grasping piece is connected to the sheath at a first rotation axis perpendicular to a longitudinal axis of the sheath. The movable member is connected to the second grasping piece at the second rotation axis parallel to the first rotation axis, and is configured to move along the longitudinal axis. The first rotation axis is configured to move within the sheath or the second grasping piece in a plane perpendicular to the first rotation axis. The second rotation axis is configured to move within the movable member or the second grasping piece in a plane perpendicular to the second rotation axis.

Abstract: A treatment instrument includes a grip and a handle. The grip is provided in an operation unit. The grip includes a first surface and a second surface provided back to back. The handle provided in the operation unit on a distal end side of the grip. The handle moves to the distal end side and the proximal end side relative to the grip. At least one of the first surface and the second surface is provided with a protrusion.
