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.

A grasping treatment instrument comprising:
- a grasping piece;
- a supporting member which is configured to open and close with respect to the grasping piece;
- a clamp member which is pivotally supported by the supporting member, and which is provided between the supporting member and the grasping piece in open and close directions of the supporting member, the clamp member including an opposed surface which is opposed to the grasping piece, and a back surface which faces to an opposite side of the opposed surface;
- and
- a cover member which is made of a material having lower thermal conductivity than the clamp member, and which is attached to the clamp member from a back surface side, the cover member covering 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,
- wherein a proximal end of the cover member is positioned on the distal side with respect to the position where the clamp member is pivotally supported by the supporting member.
