    摘要： A helical reamer for reaming a bone cavity has a longitudinally extending support shaft having a first driven end and a second end having a tip for insertion into the bone cavity. The research for a multiplicity of stamped flat reamer plates each having a plurality of cutting flutes formed on an external surface thereof and a central internal opening to receive the support shaft. The internal opening includes a coupling element in the form of a key and keyway rotationally coupling each reamer plate to the support shaft. The key and keyway allowing each reamer plate to be slightly rotated with respect to the flutes of an adjacent reamer plate. The coupling elements for rotationally coupling the plates to the drive shaft can be mating flattened areas on the internal surface of the stamping and the external surface of the drive shaft. A broach of stamped plates is also shown.

    摘要： A surgical cutting tool for cutting a seating surface of curved contour configuration in natural bone for receiving a component of a prosthetic implant at an implant site. The tool has cutting blades in a cutting blade construct placed within an arbor such that the cutting blades are supported by the arbor circumferentially spaced from one another, with cutting edges of the cutting blades exposed for cutting the seating surface. Stabilizers along the arbor stabilize the tool during a cutting operation, while channels in the arbor along the cutting blades carry away cut bone. The cutting blades are essentially flat, are economically manufactured from flat stock, are provided with a predetermined thickness and a cutting blade radius, and include cutting edges placed within the cutting blade construct circumferentially forward of the cutting blade radius to establish a gap between the cutting blade radius and a corresponding radius of the seating surface for providing an effective cutting profile along each cutting edge.
