Patent ID: 8469959

Claim:
A bone preparation device for shaping endplates forming an intervertebral disc space between two adjacent vertebrae, compromising: a cutter component having a distal end and a proximal end, the cutter component comprising: a shaft having a distal end and a proximal end; and a cutting blade carried by the shaft and disposed at the distal end of the cutter component, the cutting blade being configured and arranged to form a cut-out in the endplates of the vertebrae; a cutter-positioner component having a proximal end and a distal end connected by a longitudinal shaft extending between the proximal end and the distal end, a portion configured to be disposed distal of the cutting blade, the cutter-positioner being arranged to limit a distal travel of the cutter component and to restrict a range of motion of the distal end of the cutter component; and a rotational interface between the cutter component and the cutter-positioner component, the rotational interface being structurally arranged to permit the cutting blade to be rotated at the same time the cutter component is restricted in its range of motion, the rotational interface comprising a protrusion on the cutter component and a receiving portion comprising a pivot depression in the cutter-positioner component, wherein the rotational interface is the distal end of the shaft of the cutter component.
