Patent ID: 8523866

Claim:
A reamer for medical applications to be used for reaming a bone canal, comprising: a. a shaft portion having an elongated body, comprising: i. a proximal end having a coupling portion appointed for attachment of said reamer to a drilling device; ii. a central conical element having one or more lateral slots; and iii. a distal end having a male threaded portion; b. a disposable tapered hollow reamer sleeve having a substantially conical shape, comprising: i. an outer surface and a hollow interior said outer surface having a plurality of cutting teeth and a plurality of apertures; ii. a larger diameter end with at least one integrally attached torque transmitting tab; and iii. a smaller diameter end with a collet taper; c. a modular pilot with a central aperture having female threading and an external surface with a collet taper, an end of said modular pilot that is distal to said collet taper of the modular pilot has a bullet shape; d. said disposable tapered hollow reamer sleeve being adapted to slide over said distal end of said shaft portion, whereby said one or more slots of said central conical element engage with said at least one torque transmitting tab of said tapered hollow reamer sleeve; and e. said modular pilot being appointed for insertion said distal end of said shaft portion, whereby: i. said male threaded portion of said distal end of said shaft portion engaging engages with said female threading on said central aperture of said modular pilot and; ii. said collet taper on the external surface of said modular pilot engages with said collet taper of said hollow reamer sleeve; whereby said disposable tapered hollow reamer sleeve is appointed to ream the bone canal; and whereby torque from the shaft portion is transferred to said tapered hollow reamer sleeve with substantial coincidence of centerlines, preventing reamer wobbliness, and bone and bone cement debris is collected in a space between the tapered hollow reamer sleeve and shaft portion.
