Abstract
Method for producing a reamer such as a milling cutter intended to mill the acetabular cavity of a patient, the reamer including a rigid base with an interface for coupling to a tool holder, and including a cutter body which has a thin wall and is perforated and toothed. The rigid base is produced separately from the cutter body, by cutting out and drawing a first flat metal blank in a press.
Claims9
A method for producing a reamer for milling an acetabular cavity of a patient, comprising the steps of:
- a) forming a base by cutting out and press-stamping a first flat piece of metal, the base being generally disk-shaped and having a generally uniform thickness, the base being perforated so as to define a plurality of branches extending from a center of the base, wherein the press-stamping step includes the step of deforming the first flat piece of metal so that the branches have a U-shaped or V-shaped cross-section,
- b) forming a cutter body by providing a blank made by cutting out and press-stamping a second flat piece of metal which is separate from the first flat piece of metal,
- c) shaping the cutter body into a hemisphere, and
- d) attaching the base to the hemispherical cutter body.
