摘要:
A surface protection system comprising a protective sleeve positionable over an orthopedic tool or implant, for example the tapered end of an orthopedioc femoral stem implant to shield the covered surface from exposure to abrasive particles during an automated polishing process is described. The protective sleeve comprises a body having an annular sidewall that extends from a proximal end to a distal end and is composed of a polymeric material. A cavity resides within the body extending through the distal end to a proximal end sidewall positioned perpendicular to the annular sidewall. The protective sleeve further comprises at least one annular recess intermediate at least two annular ridges that reside along an interior surface at the distal end of the sleeve. These series of annular ridges and recesses form a removably tight seal around the exterior surface that minimizes the migration of abrasive polishing particles to the exterior surface of the orthopedic tool or implant. The system further comprises an impactor and extractor tools which facilitate the positioning and removal of the protective sleeve from the surface thereof.
