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.

Treatment instrument

An energy treatment instrument includes a pair of grasping pieces, and the grasping pieces grasp a treated target therebetween by closing relative to each other. At least one of the grasping pieces includes an energy applying portion which treats the treated target by applying treatment energy to the grasped treated target. At least one of the grasping pieces includes a hauler hauling the treated target toward an inside in a width direction of the grasping pieces, when the grasping pieces close relative to each other in a state that the treated target is disposed between the grasping pieces.

Energy treatment instrument and energy treatment system

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.
