Abstract: An electrically conductive plate of a treatment instrument includes a treating surface and a back surface facing an opposite side of the treating surface, and an electric component is arranged on the back surface of the electrically conductive plate. The electric component is electrically independent from the electrically conductive plate, and a holder supports the electrically conductive plate from the back surface side. A connector is made of a thermoplastic resin, and arranged on either side of and spaced from the electric component in a width direction intersecting with a longitudinal axis. The connector stationarily fixes each end of the electrically conductive plate in the width direction to the holder.

Abstract: In a grasping treatment unit in which a first jaw is openable and closable relative to a second jaw, a frame member is provided in the first jaw. The frame member includes a plate-shaped base portion forming a grasping surface side end face in the frame member, and a column extension extending from the base portion toward a back surface in the frame member and having one end continuous with the base portion. The column extension defines a space in which the frame member is a defining surface between the base portion and the back surface of the first jaw.

Abstract: A grasping treatment unit includes a first jaw, and a second jaw openable and closable relative to the first jaw. In the first jaw, a heating wire continues without branching from a first extending end to a second extending end, and generates heat over an entire length from the first extending end to the second extending end when an electric current flows therethrough. A heating portion is lower in calorific value per unit area in a distal portion than in a proximal portion in the first jaw in a state where the heat is generated from the heating wire.

Abstract: A treatment system includes a pair of holding members, a high-frequency energy output section, a heat generating section and a control section. At least one of the pair of holding members moves to the other holding member. The high-frequency energy output section and the heat generating section are provided on at least one of the holding members. The high-frequency energy output section exerts high-frequency energy to a living tissue to denature the living tissue, and collects the biological information of the living tissue. The heat generating section applies heat to it held between the holding members, generates the heat owing to the supply of the energy, and conducts the heat therefrom to denature the living tissue. The control section controls the output of the energy to the high-frequency energy output section and the heat generating section based on the biological information collected by the high-frequency energy output section.

Abstract: In a blade of a grasping treatment unit, a top sharpening toward a jaw forms a ridge line along a longitudinal direction of the blade, and in the jaw, a grasping surface opposed to the top extends. A proximal side counter portion, on which the top can abut while the blade and the jaw are closed relative to each other, is provided in a region of the grasping surface located on a proximal side with respect to a distal portion, and a distal side counter portion, which does not contact the top while the top abuts on the proximal side counter portion, is provided in the distal portion of the grasping surface.
