    Abstract: A grasping treatment instrument includes a grasping piece, and a supporting member opening and closing relative to the grasping piece. A clamp member is provided between the supporting member and the grasping piece in open and close directions of the supporting member, and the clamp member includes an opposed surface opposed to the grasping piece, and a back surface facing to an opposite side of the opposed surface. The grasping treatment instrument includes a cover member made of a material having lower thermal conductivity than the clamp member, and the cover member covers the clamp member from the back surface side in a part on a distal side with respect to a position where the clamp member is pivotally supported.

    Abstract: The disclosed technology is directed to a treatment tool comprises a shaft to extend from a proximal-end side toward a distal-end side. A first jaw is disposed on the distal-end portion of the shaft. A second jaw having a gripping surface that faces the first jaw, an opposed back surface of the gripping surface and a first engaging portion. The second jaw is angularly movable about a turn axis of the first engaging portion so as to be opened or closed with respect to the first jaw. A movable shaft having a recess defined in a distal-end and is movable along the longitudinal axis with respect to the shaft for angularly moving the second jaw about the turn axis with respect to the first jaw. A cover having a protrusion that protrudes toward a proximal-end side of the second jaw and a second engaging portion formed on the protrusion.
