title: Usefulness of the novel evolutional anvil grasper for laparoendoscopic surgery for intracorporeal circular stapled anastomosis during laparoscopic colorectal surgery.
abstract: Traditional anvil graspers cannot delicately handle the anvil head as a result of their unique jaw shape that enhances grip force, and they are not suitable for confined pelvic space. With a manufacturing company, we developed a novel anvil grasper, the evolutional anvil grasper for laparoendoscopic surgery (EAGLE), to ensure more precise and safer anastomosis procedures. The EAGLE has curved blades that create a 6-mm grasping surface that is the same diameter as the anvil stem and is covered with tungsten carbide tips. When using the EAGLE, a surgeon grasps the anvil stem slightly and easily, handles the anvil head and proximal colon, and smoothly sets the anvil to the center rod of the circular stapler. A surgeon can also securely grasp the stem of the anvil, push it into the center rod of the circular stapler and then perform a sequence of actions in anastomosis procedures smoothly and safely.
