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.
Claims8
A method of processing bone, comprising:
- positioning bone at least partially covered with tissue comprising at least one of muscle, periosteum and connective tissue in a bone denuding device;
- coupling an impeller to a power source of the bone denuding device, wherein the impeller includes a plurality of blades formed of a polymer;
- positioning the impeller in a cutting drum having a cutting surface such that, upon rotation of the impeller, at least one blade of the impeller urges the bone against the cutting surface;
- operating the power source to rotate the impeller so as to separate the tissue from the bone to produce denuded bone;
- and
- operating a bone milling device to morselize the denuded bone and produce morselized bone particles.
A method of processing bone, comprising:
- placing a bone at least partially covered with tissue comprising at least one of muscle, periosteum and connective tissue inside a sterile casing, the sterile casing including an impeller and a drum having a cutting surface, wherein the impeller includes a plurality of blades formed of a polymer;
- coupling at least one of the impeller and the drum to a power source;
- rotating the at least one of the impeller and the drum with the power source such that the plurality of blades urge the bone against the cutting surface to remove the tissue from the bone;
- and operating a bone milling device to morselize the bone and produce morselized bone particles.
