Abstract: A stapling device developed for orthopaedic use is in two cooperable parts including: a locator (10) in the form of a generally tubular member having a pair of opposed parallel grooves (16) extending longitudinally over one end portion of the inner surface of the member to receive the legs of a staple (30) of appropriate size entered head first into the one end, and having pin or other penetrating means (17) projecting from the one end of the member for a short length compared to the grooves to be entered into bone or other material to stabilize the locator in a desired position relative thereto; and a punch (20) longer than the locator and slidable therein over substantially the whole locator length from its other end to drive a staple therefrom. The one end portion of the locator preferably has its interior narrowed to a slot form (14) with the grooves at the slot ends, and its exterior tapered or otherwise similarly shaped with pins at each end adjacent the grooves, to facilitate staple location.
