Abstract:
An instrument for inserting a graft fixation device into bone, said instrument comprising:an elongated member having a proximal end and a distal end and an outer surface; outer screw threads extending out from the outer surface about the distal end; a distal end surface adjacent to the distal end of the elongated member; a hollow member having a cavity, a proximal end and a distal end, and an outer surface and an inner surface, said hollow member having an opening in the proximal end in communication with hollow cavity; inner screw threads extending out from the inner surface of the hollow member; a pair of spaced apart prong holes extending through the distal end of the hollow member, said prong holes being in communication with the cavity; a retention groove extending into the inner surface of the distal end of the hollow member; a pair of prongs, said prongs comprising elongated members having distal ends and proximal ends; a point extending distally from the distal end of each prong; a retention member mounted to the proximal end of each prong, the retention member having a proximal surface; wherein the instrument is assembled by first inserting the prongs through the prong holes, such that the prongs extend through the prong holes, and the proximal retention members are contained within the retention groove, and the hollow member is then screwed onto the distal end of the elongated member, by engaging the mating inner threads with the outer threads, such that the distal end surface of the elongated member engages the proximal surface of each retention member.
