Abstract:
1. A tool for stabilizing a fractured bone, comprising: a barrel having a proximal end and a distal end, the distal end of the barrel including a passageway for receiving a bone pin configured to be driven into the fractured bone to stabilize the fractured bone, the passageway being sized to accommodate axial movement of the bone pin through the passageway while limiting radial movement of the bone pin in the passageway; a piston having a proximal end and a distal end and configured to translate axially relative to the barrel, the proximal end of the piston including a head and the distal end of the piston including a needle formation sized for receipt within the passageway of the barrel; a cartridge for receiving the bone pin, the cartridge configured to be supported at the distal end of the barrel, wherein the cartridge includes an at least partially cylindrical body having an outer surface sized to fit within a nose portion at the distal end of the barrel, and an inner surface at least partly defining at least one passageway for receiving the bone pin; and a dial coupled to the tool for rotating the cartridge to selectively align the at least one passageway with the needle formation, wherein the needle formation configured to apply sufficient force to the bone pin to drive the bone pin axially from the barrel and into the fractured bone.
