DISTAL REAMER FOR USE DURING AN ORTHOPAEDIC SURGICAL PROCEDURE TO IMPLANT A REVISION HIP PROSTHESIS
First Claim
Patent Images
1. A distal reamer operable to ream an intramedullary canal of a patient'"'"'s femur during a surgical procedure to implant a distal stem component of a modular orthopaedic hip prosthesis, comprising:
- an elongated shank having (i) a cutting head formed in a distal end of the elongated shank, the cutting head having a plurality of helical cutting flutes arranged in a geometry that corresponds with the geometry of the distal stem component, and (ii) a drive connector formed in a sidewall positioned at an opposite, proximal end of the elongated shank, the drive connector having (a) a female drive socket, and (b) a number of locking slots formed in the sidewall so as to open into the female drive socket.

10. A surgical instrument assembly operable to ream an intramedullary canal of a patient'"'"'s femur during a surgical procedure to implant a distal stem component of a modular orthopaedic hip prosthesis, comprising:
-
a distal reamer having (i) a cutting head that includes a plurality of helical cutting flutes arranged in a geometry that corresponds with the geometry of the distal stem component, and (ii) a female drive socket, and an extension tool having (i) a connector configured to couple the extension tool to a rotary drive source, and (ii) a drive spline positioned in, and engaged with, the female drive socket of the distal reamer such that rotation of the extension tool causes rotation of the distal reamer. - View Dependent Claims (11, 12, 13, 14)
