Abstract: A treatment tool includes a first grasper and a second grasper. The first grasper includes a treatment portion that includes a treatment surface and an opposing surface, and a holder portion that is mounted on the opposing surface. The holder portion is formed of an elastically deformable material, and includes a first region having a first contact surface, a second region having a second contact surface, and a connection region that is arranged between the first contact surface and the second contact surface and that includes a concave portion. The holder portion is mounted on the opposing surface in an elastically deformed state such that the first contact surface and the second contact surface are in contact with the opposing surface and such that a depth of the concave portion is smaller than a depth of the concave portion is a non-elastically deformed state.

Abstract: An ischemia control device is connected to a control unit that receives inputs from sensors and other surgical devices that senses patient conditions. The control unit uses the data inputs, as well as direct inputs from the medical operators, to output opening and closing instructions to the ischemia control device. The actuator on the ischemia control device receives the opening and closing instructions and manipulates the ischemia control device. The ischemia control device can be automatically operated using the sensed information to intermittently and alternately achieve ischemia of the organs and reperfuse the organs and, thereby, protect the organs from being damaged by the ischemia.
