Patent ID: 8403931

Claim:
A reamer for medical applications, comprising: a. a shaft portion having an elongated body with a proximal end, a central conical element and a distal end, said proximal end having a coupling portion appointed for attachment of said reamer to a drilling device, said central conical element having one or more lateral slots said distal end having a threaded portion; b. a disposable tapered hollow reamer sleeve, comprising: 1. a tapered hollow reamer sleeve having an outer surface and a hollow construction, said disposable hollow cutter sleeve portion further comprising a plurality of cutting teeth and a plurality of apertures on said outer surface; and 2. said tapered hollow reamer sleeve having a larger diameter end with at least one integrally attached torque transmitting tab; 3. said tapered hollow reamer sleeve having a smaller diameter end with a collet taper; c. a modular pilot with a central threading and a external surface with a collet taper; d. said disposable tapered hollow reamer sleeve being adapted to slide over said distal end of said shaft portion and said slots of said central conical element with engaging torque transmitting tabs of said tapered hollow reamer sleeve; and e. said modular pilot being inserted at a distal end of said shaft engaging threads and said collet taper on the external surface engaging with said collet taper of said hollow reamer sleeve; whereby torque from the shaft is transferred to said tapered hollow reamer with substantial coincidence of centerlines, preventing reamer wobbliness, and bone and bone cement debris is collected in the space between the tapered hollow reamer and shaft.
