Abstract
A method to remove a memory metal orthopedic staple from that is implanted in a bone repair site is disclosed. The orthopedic staple is in its relaxed state and the method includes (a) attaching an inserter tool/cartridge assembly to the orthopedic staple's bridge portion; (b) actuating the inserter tool to change the orthopedic staple from its relaxed state to its insertion state in which the two legs of the orthopedic staple are substantially parallel to each other; and (c) removing the orthopedic staple from the bone repair site.
Claims8
A bone staple inserter kit comprising:
- a first sterile package containing a first bone staple securely mounted to a first cartridge, wherein
- the first bone staple includes a first leg, a second leg, and a bridge portion connecting the two legs, the bridge comprising a flat top surface along a length of the bridge portion where the flat top surface forms a convex portion that is spaced-away and laterally off-set from each of the first leg and the second leg and, having a first end opposite a spaced-away second end, and two chamfered edge surfaces that extend substantially the length of the bridge portion, the flat top surface positioned between the two chamfered edge surfaces,
- wherein the flat top surface extends substantially the length of the bridge portion, so that the bridge portion defines a uniform cross-section,
- wherein each of the first end of the bridge portion transitions down to the first leg and the second end of the bridge portion transitions down to the second leg, and the first cartridge comprises a first end and a second end, the first end provided with a channel that is sized to receive the bridge portion of the first bone staple and securely hold the first bone staple by an interference fit;
- and
- a second sterile package containing:
- a bone staple insertion tool that is configured to receive a cartridge, like the first cartridge that has a bone staple, like the first bone staple, securely mounted thereon;
- a universal drill guide assembly;
- and a drill bit, wherein the bone staple insertion tool comprises a lever and a pushrod that can transform the bone staple to an insertion shape after the cartridge with the bone staple mounted thereon is mounted on the insertion tool;
- and wherein the lever is operatively linked to the pushrod such that actuation of the lever directly causes linear movement of the pushrod so as to engage the convex portion of the bone staple.
