Claim:
A surgical plate-pulling system that facilitates pulling a fastener receiving member against a bone surface, comprising: (a) a fastener comprising an elongate section and an adjoining head section disposed along a fastener axis, the head section comprising a thread; (b) a fastener receiving member comprising first and second opposing major surfaces, an inside surface extending between the first and second major surfaces and defining an aperture generally coaxially disposed about an aperture axis, and a tappable contact region disposed on the inside surface; and (c) a plate puller device including a grasper portion that is configured to fit around a screwdriver, and a grasper sleeve positioned around the grasper portion, the plate puller device configured for facilitating the fastener receiving member to be pulled against a bone surface during insertion of the fastener therethrough by preventing the head section of the fastener from engaging the tappable contact region of the fastener receiving member until the fastener receiving member is pulled against the bone surface by the grasper portion and grasper sleeve being in cooperative engagement such that the grasper portion grips the head section of the fastener to prevent the head section of the fastener from advancing within the aperture of the fastener receiving member wherein the fastener is a surgical bone screw, the fastener receiving member is a surgical bone plate, the head portion of the grasper portion comprises a plurality of radially displaceable wedges and the grasper sleeve may be advanced against the plurality of radially displaceable wedges such that the plurality of radially displaceable wedges compress around the head section of the fastener, thereby preventing the head section of the fastener from advancing within the fastener receiving member, and each wedge comprises a triangular wedge shaped cross-section with a flat bottom surface for preventing the head section of the fastener from engaging the fastener receiving member by the flat bottom surface abutting against the fastener receiving member to pull the fastener receiving member toward the bone surface.
