Abstract: An energy surgical instrument includes a first grasping piece, a second grasping piece which is allowed to grasp a blood vessel, an energy application unit provided in at least one of the first grasping piece and the second grasping piece, which applies treatment energy to the blood vessel grasped, a setting unit which sets information regarding a wall thickness of the blood vessel, and a grasping force adjustment unit which adjusts a grasping force to a first grasping force when the wall thickness set by the setting unit is larger than a predetermined thickness and adjusting the grasping force to a second grasping force, which is smaller than the first grasping force, when the wall thickness set by the setting unit is equal to or smaller than the predetermined thickness.

Abstract: 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.

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: An energy surgical instrument includes first and second grasping pieces for grasping a blood vessel. At least one of the grasping pieces is designed to apply treatment energy to a grasped blood vessel. The instrument also includes a processor designed to set a wall thickness of the blood vessel, and a grasping force adjuster designed to adjust a grasping force applied by the first and second grasping pieces. A first grasping force is applied when the wall thickness set by the processor is larger than a predetermined thickness, and a second grasping force, which is larger than the first grasping force, is applied when the wall thickness set by the processor is equal to or smaller than the predetermined thickness. A treatment method includes applying treatment energy to a blood vessel grasped by the first and second grasping pieces of the instrument to seal the blood vessel.
