Abstract
An apparatus for cutting a bone plug from a portion of bone. A base vertically supports a block. An arm has one end hinged to the block and carries a handle at the other end thereof. A sleeve is connected to the block and extends below the handle. A plunger is disposed within the sleeve and connected to the arm via a roller pin and roller which are disposed in an arcuate slot in the handle. The lower end of the plunger carries a die for cutting the bone plug. The handle is raised, pivoting the arm and causing the plunger to move within the sleeve and away from the base. A portion of bone from which the bone plug is to be cut is placed between the die carried on the plunger and the base. As the handle is moved downward toward the base, the lever action forces the plunger to close onto the portion of bone causes the die to penetrate the portion of bone resulting in a bone plug cutting. A plurality of stems may be located on the sleeve or provided on a separate flat plate for storing extra dies. In addition, a stem is located on the base to aid in removing the bone plug from the die.
