Abstract
A system and method of processing bone is disclosed. A tissue separator is utilized to separate tissue comprising at least one of muscle, periosteum and connective tissue from bone in a safe, sterile and efficient manner. In one aspect, the particle reducer can include an impeller positioned with respect to a cutting surface on a drum. At least one of the impeller and the drum is rotated by a power source such that harvested tissue frictionally engages the cutting surface. In another aspect, a source of pressurized fluid can be directed at tissue to separate bone from non-bone tissue.
Claims16
A bone denuder comprising:
- a cutting drum having a cutting surface;
- an impeller positioned within the cutting drum;
- a shaft coupled to the impeller to rotate therewith;
- and
- a power source coupled to the shaft to provide rotational force thereto,
- wherein the impeller is eccentric with respect to the cutting drum.
A bone denuder comprising:
- a cutting drum having a cutting surface, the cutting drum rotatable about a central axis;
- and
- an impeller positioned within the cutting drum and configured to operably engage a shaft for rotation about a common axis, the shaft adapted to couple to a power source to provide rotational force thereto,
- wherein the common axis shared by the impeller and the shaft is laterally offset from the central axis of the cutting drum.
