Endoscopic intracorporeal suture tying aid

摘要

An endoscopic intracorporeal suture tying aid allows a suture to be looped around itself multiple times and cinched, enabling a throw of a surgeon's knot to be easily made. The tying aid includes a needle holder connected to a proximal end of a shaft for releasably holding a needle; a hook that slides longitudinally with respect to the beaks; and the shaft being axially rotatable with respect to the hook.
