Bone cleaning assembly with a rotating cutter that is disposed in a rotating shaving tube that rotates independently of the rotating cutter

An assembly for cleaning bone stock, said assembly comprising:

• a shell defining a void space for receiving the bone stock to be cleaned;
• a cutter mounted in the shell void space for rotation, said cutter having at least one cutting edge;
• a shaving tube rotatably mounted in the shell void space so as to be extend around said cutter, said shaving tube having a window that is defined by at least one shaving edge, such that said cutter and said shaving tube are positioned so that the at least one cutting edge of said cutter and said shaving edge of said shaving tube cooperate to cut soft tissue from the bone stock and, wherein said shaving tube is able to rotate in having tube being rotatably mounted in the shell void space;
• a guide moveably disposed in said shell to move between a disengaged position and an engaged position and is configured to, when moving from the disengaged position to the engage position, urge bone stock towards the window of said shaving tube and said cutter;
• and
• a drive assembly connected to said cutter, said shaving and said guide for actuating said, cutter, said shaving tube and said guide wherein said drive assembly is adapted to, when actuating said shaving tube and said cutter, cause said shaving tube and cutter to rotate at different speeds or directions relative to each other or to cause said cutter to be rotated continually while said shaving tube rotates periodically and said drive assembly is further configured to cyclically move said guide between the disengaged and engaged positions of said guide.

• a tumble plate rotatably disposed in said shell such that said cutter and said shaving tube extend upwardly from said tumble plate so that the bone stock seats on said tumble plate;
• and
• a drive assembly connected to said cutter, said shaving and said tumble plate for rotating said cutter, said shaving tube and said tumble plate wherein said drive assembly is adapted to, when rotating said shaving tube and said cutter, cause said shaving tube and cutter to rotate at different speeds or directions relative to each other or to cause said cutter to be rotated continually while said shaving tube rotates periodically and said drive assembly is further configured to cyclically move said guide between the disengaged and engaged positions of said guide
