1. A tool for stabilizing a fractured bone, comprising:
- a housing;
a cartridge supported by the housing and including at least one passageway that receives at least one bone pin, the at least one bone pin configured to be driven into the fractured bone to stabilize the fractured bone; and
a piston having a proximal end and a distal end and is configured to translate axially relative to the housing, the piston including a head arranged toward a proximal end of the tool, a shaft extending from the head, and a needle coupled to the shaft, the needle sized for receipt within the at least one passageway of the cartridge, the needle configured to apply sufficient force to the at least one bone pin to drive the at least one bone pin axially from the cartridge and into the fractured bone, wherein the cartridge is configured to rotate to align the at least one passageway with the needle.

Abstract
A tool and a method are provided for driving a bone pin into a fractured bone to stabilize the fractured bone by maintaining the fractured bone in a reduced state. The tool may be a handheld device including a cartridge having at least one passageway that receives the bone pin. The tool may also include a pneumatically-powered piston having a needle that is sized for receipt within the passageway of the cartridge, the needle applying sufficient force to the bone pin to drive the bone pin out of the cartridge and into the fractured bone.

17. A tool for stabilizing a fractured bone, comprising:
-
a housing; a cartridge supported by the housing and including a plurality of passageways that receive a plurality of bone pins configured to be driven into the fractured bone to stabilize the fractured bone; and a piston having a proximal end and a distal end and is configured to translate axially relative to the housing, the piston including a head arranged toward a proximal end of the tool, a shaft extending from the head, and a needle coupled to the shaft, the needle sized for receipt within the plurality of passageways, the needle configured to apply sufficient force to the plurality of bone pins positioned within the plurality of passageways to drive the plurality of bone pins axially from the cartridge and into the fractured bone, wherein the cartridge is configured to move between a first position and at least a second position, wherein, at the first position, a first passageway of the plurality of passageways is aligned with the needle, and at the second position, a second passageway of the plurality of passageways is aligned with the needle. - View Dependent Claims (18, 19)

20. A system for stabilizing a fractured bone, comprising:
-
a handheld tool, including; a housing; a cartridge supported by the housing and including at least one passageway; and a piston having a proximal end and a distal end and is configured to translate axially relative to the housing, the piston including a head arranged toward a proximal end of the handheld tool, a shaft extending from the head, and a needle coupled to the shaft, the needle radially offset from the shaft and sized for receipt within the at least one passageway of the cartridge; and one or more bone pins sized and configured to be received within the at least one passageway, wherein the needle is configured to apply sufficient force to the one or more bone pins to drive the one or more bone pins axially from the cartridge and into the fractured bone, wherein the cartridge is configured to rotate to align the at least one passageway with the needle.
