Abstract: A jaw of a grasping treatment device includes a non-contact portion having a space between it and a distal treatment section in a state where an abutment portion abuts on the distal treatment section, and the non-contact portion includes a wall surface portion inclined so that it is extended toward a distal treatment section side as it is extended away from the abutment portion. A movement regulating portion is provided in a region of the non contact portion located closer to the abutment portion than a continuous surface which forms an edge of the non-contact portion. The movement regulating portion located in the first wall surface portion regulates a movement of a grasp object along the jaw axis direction.

Abstract: A handle unit for a surgical device that operates an end effector to give various kinds of treatments, includes: a handle main body having a fixed member; a support section that is supported by the same hand of the user and is movable along a turning plane defined by moving closer to or away from the fixed member; a first coupling section that is coupled with the handle main body by moving the support section along the turning plane; a second coupling section that has an extended axis defined by the first coupling section and the support section and is configured to turn the support section in a periaxial direction orthogonal to the extended axis; and a third coupling section that is configured to turn the support section in the periaxial direction of the extended axis.

Abstract: A jaw of the grasping treatment device includes an abutting portion being abutable on a probe treatment portion when the jaw is closed relative to the probe treatment portion, and a separated portion being disposed with a clearance between the separated portion and the probe treatment portion when the abutting portion is in abutment with the probe treatment portion. The jaw includes a distal-side wall portion provided to a distal direction side of the separated portion and protruding toward the probe treatment portion as compared with the separated portion, and a proximal-side wall portion provided to a proximal direction side of the separated portion and which protruding toward the probe treatment portion as compared with the separated portion.

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.
