Patent ID: 8920423

Claim:
A bone harvesting device including: a drill for drilling into bone, said drill being a cylinder having a forward edge at an end thereof, the drill being rotatable about its longitudinal axis, for making a longitudinal circular cut into the bone for forming a cylindrical drilled bone portion as the drill is advanced into the bone, the drill having a cavity for receiving the drilled bone portion therein, the cavity having an opening at the forward end of the drill through which the cylindrical drilled bone portion passes into the cavity, a cutter disposed in proximity to the opening which is pivotable relative to said drill about a pivoting axis which is substantially parallel to said longitudinal axis of said drill wherein said cutter is pivotable relative to said drill between a first position in which said cutter is clear of said opening to permit the drilled bone portion to pass through the opening into the cavity and a second position in which said cutter blocks at least part of said opening to hold the drilled bone portion in the cavity, and wherein, during movement of said cutter between said first position and said second position, said cutter moves across a plane which is substantially perpendicular to said pivoting axis, thereby cutting through and detaching the drilled bone portion from the bone, for removal with the drill.
