Patent ID: 8257357

Claim:
A combination of an oscillating orthopedic reshaping and resurfacing tool and a surface-matching sheet metal prosthesis, designed to reshape and resurface bone ends in the orthopedic surgical repair; said oscillating orthopedic reshaping and resurfacing tool comprising: a motor housing containing a motor having a rotatable motor shaft with an end eccentric to the longitudinal axis of said motor shaft; a bearing mounted onto said eccentric end; a removable and replaceable cutting head, wherein said cutting head is one of many removable and replaceable cutting heads, each having a cutting surface comprised of abrasive particles, wherein said cutting heads are mounted onto said bearing; a removable and replaceable elastomeric cover, incorporating an annular containment cup which flexibly mounts and retains said cutting head to said motor housing and seals said cutting head against said motor housing and against said bone end to be resurfaced, said cup further incorporating an incoming sterile-liquid tube and an out going waste-liquid tube whereby cutting debris may be flushed and removed during the surgical reshaping and resurfacing of the bone end; a hand grip; a power conduit; an on/off control; and wherein said combination further comprises a surface-matching sheet metal prosthesis, stamped from orthopedic sheet metal, wherein said prosthesis is one of many surface-matching sheet metal prostheses, configured to be attached to the surface configuration of the bone end, after said cutting surface of said cutting head has resurfaced said bone end, said prosthesis further comprises at least one locating attachment on which it can be mounted to said resurfaced bone end.
