Abstract:

A universal drill guide system includes a universal drill guide, interchangeable drill tubes, and interchangeable drill bits. Each interchangeable drill tube corresponds to one of the interchangeable drill bits, and can be detachably coupled to the universal drill guide. A cannulated drill with K-wire retention features a drill bit with a retention mechanism that prevents axial advancement of a K-wire during drilling. A drill removal tool includes a drill remover that can be placed around a drill bit to remove it from bone after a hole is drilled, while leaving a K-wire in place in the bone. A bone screw driver with K-wire retention includes a shaft that can be passed over a K-wire, a distal end for attachment to a cannulated bone screw, and a K-wire retention module for preventing advancement of the K-wire as the screw driver drives the cannulated bone screw into bone.
