Abstract

An orthopaedic reamer includes a shell and a cutting tooth arrangement formed in the shell. The cutting tooth arrangement includes a cutting tooth having a predefined profile with a cutting edge having a cutting depth, and a depth-of-cut feature positioned forward of the cutting tooth, relative to a direction of movement of the shell at the location of the cutting tooth. The depth-of-cut feature has a control depth which controls a cutting depth of the cutting tooth during surgery.

Claims (10)

1. An orthopaedic reamer, comprising: a shell; and at least one cutting tooth arrangement formed in the shell, the at least one cutting tooth arrangement including: a cutting tooth having a predefined profile with a cutting edge having a cutting depth; and a depth-of-cut feature positioned forward of the cutting tooth, relative to a direction of movement of the shell at the location of the cutting tooth, the depth-of-cut feature having a control depth which controls a cutting depth of the cutting tooth during surgery, wherein the cutting tooth and the depth-of-cut feature both extend outwardly from a surface of the shell.

2. The orthopaedic reamer of claim 1 , wherein the depth-of-cut feature is configured as a skid.

3. The orthopaedic reamer of claim 1 , wherein the at least one cutting tooth arrangement comprises a plurality of the cutting tooth arrangements formed in the shell, each of the cutting tooth arrangements being substantially identically configured.

4. The orthopaedic reamer of claim 1 , wherein the shell defines a hole therethrough, the cutting tooth being located on a first side of the hole and the depth-of-cut feature being on a second side of the hole that is opposite the first side.

5. The orthopaedic reamer of claim 4 , wherein the cutting edge faces forwardly and the depth-of-cut feature includes an edge facing the cutting edge.

6. The orthopaedic reamer of claim 4 , wherein the hole is round.

7. The orthopaedic reamer of claim 1 , wherein the cutting tooth defines a tooth length and the depth-of-cut feature defines a length that is less than the tooth length.

8. The orthopaedic reamer of claim 1 , further comprising a driver connector disposed in the shell.

9. The orthopaedic reamer of claim 1 , wherein the shell is a hemispherical shell.

10. The orthopaedic reamer of claim 1 , wherein the shell comprises a metal.
