BONE GRAFT DELIVERY APPARATUS

摘要

A magazine supporting multiple bone grafts in chambers is coupled to a housing including a barrel. A plunger selectively passes through one of the chambers and along the barrel. A trigger mechanism advances the plunger along the barrel. A selector knob is movable into a plurality of positions, wherein each position employs one of a plurality of stops. One stop prevents the end of plunger from advancing past a predetermined ready position short of the end of the barrel when selected. Another stop prevents the plunger from advancing past a predetermined dispensing position substantially aligned with the end of the barrel when selected. Another stop prevents the plunger from advancing past a predetermined manipulating position beyond the end of the barrel when selected. In the manipulating position, the distal end of the plunger can be used to reposition the bone graft within the spinal disc cavity. Related methods are also provided.

1. A bone graft delivery apparatus comprising:
a housing comprising a barrel and a handle; a magazine coupled to the housing and having a plurality of chambers, each of the chambers being configured to support a bone graft; a plunger supported by the housing and configured to selectively pass through one of the chambers and along the barrel, a selector knob operably coupled to a plurality of stops coupled to the plunger, the selector knob being movable into a plurality of positions, wherein each position employs one of the stops; a trigger mechanism supported by the housing and operably coupled to the plunger to advance the plunger along the barrel; wherein a first of the stops prevents the plunger from being moved forward past a first predetermined plunger position when the selector knob is in a first of the positions, and wherein a second of the stops prevents the plunger from being moved forward past a second predetermined plunger position when the selector knob is in a second of the positions.
