Also described are methods for using a implanting device for driving a fastener or fixation element into bone and a kit comprising a pneumatic implanting device for driving a fastener or fixation element into bone.
Claims28
An implanting device for driving a fastener or fixation element into bone, comprising:
- a chamber for holding at least one fastener or fixation element,
- a barrel having a proximal end and a distal end, wherein said proximal end is connected to said chamber for propelling said fastener or fixation element from said chamber,
- a propellant source functionally connected to said chamber, the propellant source comprising a propellant gas, and
- a triggering mechanism for releasing propellant from said propellant source into said chamber and charging said chamber in order to drive said fastener or fixation element from said chamber through said barrel and drive said fastener or fixation element into bone contacted with said distal end, wherein said propellant gas directly engages said fastener or fixation element to drive the fastener or fixation element without the use of a piston.
