Abstract: The disclosed technology is directed to a treatment tool comprises a first grasping jaw having a first grasping surface. A second grasping jaw having a second grasping surface and is configured to engage with the first grasping jaw so as to relatively pivot with respect to one another for holding a living tissue therebetween. A first electrode is disposed on the first grasping surface. A second electrode is disposed on either the first grasping surface or the second grasping surface and is configured to generate high-frequency energy in tandem with the first electrode to the living tissue held therebetween. A floating electrode is disposed in at least one of the first grasping surface and the second grasping surface. The floating electrode includes respective first and second ends each of which is disposed between the first electrode and the second electrode.

Abstract: A treatment tool includes a first grasping jaw having a first grasping surface. 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. When the first grasping surface and the second grasping surface confront each other, the first electrode and the second electrode are disposed in respective positions on both sides of a central position of the heat generator.
