A second grasping jaw has a second grasping surface and is configured to engage with the first grasping jaw so as to pivot with respect to one another for holding a living tissue. A first electrode is disposed on the first grasping surface. A second electrode is disposed on one of the first grasping surface and in tandem with the first electrode supplies heat to the living tissue. A heat generator is disposed on at least one of the first grasping jaw and the second grasping jaw for generating heat when electrically energized.
