Abstract
A fixed operation handle is provided at the proximal end portion of a sheath and a movable operation handle is rotatably connected to the fixed operation handle. A coupling rod engages with the movable operation handle so as to freely move the rod back and forth. An operation shaft is threadably coupled to the coupling rod and a forceps is connected to the distal end of the operation shaft. At the areas of the coupling rod and fixed operation handle through which the coupling rod is inserted, first and second stopper units are provided for adjustably restricting an end-of-forward and end-of-backward movement of the coupling rod, thereby serving as a stopper for opening and closing the movable operation handle.
