  • Acetabular/patellar/glenoid/calcar reamer cutting tooth arrangment with depth-of-cut control feature
    Patent number: 11033282
    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.

  • METHOD OF MANUFACTURING AN ORTHOPAEDIC REAMER
    Publication number: 20070118137
    Abstract: A method of manufacturing an orthopaedic reamer includes the steps of: forming a shell having a cutting face; cutting a plurality of openings in the shell, each opening defining a cutting edge of a tooth and a pair of relief cuts extending transverse from opposite ends of the cutting edge, each relief cut terminating at a base end; and bending each cutting tooth in a single bending operation about an axis extending between the base ends, with each cutting edge having a shape after the bending step which is predefined by the cutting step.
