CONTOURED REAMER TEETH

摘要

An acetabular reamer (10') for cutting a required cut shape. The reamer has a cutting shell (12´) having a series of doubly curved cutting teeth (16´) thereon of a quantity to substantially reduce a cutting pressure on each tooth as well as to reduce a size of a typical chip generated upon cutting. Substantially all the teeth each have a matched arc cutting edge (20´) of substantial length that has a cutting profile which substantially matches a profile of a shape to be cut. Such a configuration reduces the number of teeth required to cut the shape.
