Abstract
The present invention is an apparatus for cutting allograft bone implants from donor bone. Die sets of standard sizes are installed in a press. Donor bone is then placed in position between the upper and the lower parts of a matched cutting set comprising a hollow cylindrical cutting blade, a mandrel, and a table which establishes a gap around the mandrel which guides the blade. After the bone to be shaped has been properly placed, a shaped cutting blade is driven through the donor bone, producing a precisely shaped allograft implant. The invention provides for rapid change out of blades, rapid cleaning, and easy maintenance.
