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.

Abstract: A tool driver including a shaft having a longitudinal axis and opposite ends. A first partial boss is located at one of the shaft ends, a tool collet at the other of these shaft ends, and a second partial boss having a bore extending therethrough. The second partial boss being positioned on the shaft with the shaft in the bore. There is a stop on the shaft. The second partial boss is slidable on the shaft between the first partial boss and the stop. A spring is positioned between the second partial boss and the stop. The spring urges the second partial boss into engagement with the first partial boss. The first and second partial bosses are complementary to each other and are in engagement with each other defining a bayonet type latch mechanism. The latch mechanism has an axially extending inwardly tapered bore extending from one end coaxially of the shaft into the first and second bosses.

Abstract: A lipping tool for lipping an acetabular reamer, the lipping tool comprising a bending form having a bending form curved surface and a bending form axis of rotation; and a pressure tool having a pressure tool curved surface adjacent to and complimentary with the bending form curved surface. The pressure tool has a pressure tool axis. The pressure tool being rotatable about the pressure tool axis, the pressure tool being also rotatable about the bending form axis.

Abstract: An orthopaedic reamer, including a generally hemispherical shell having a plurality of tongues. Each tongue partially defines a corresponding C-shaped opening with a substantially constant width. Each tongue includes a cutting segment. The cutting segment includes at least one notch and a plurality of cutting teeth. Adjacent cutting teeth are separated by a corresponding notch.

Abstract: An orthopaedic reamer assembly includes a reamer with a generally hemispherical shell having a concave side and at least one attachment feature associated with the concave side. A driver is attachable to the reamer. The driver includes a shaft with a reamer end. The reamer end removably attaches to at least one attachment feature.

Abstract: An orthopaedic reamer assembly for minimally invasive surgery including a reamer and a driver. The driver includes a shaft with a distal end and a longitudinal axis; and a driver head connected to the distal end. The driver head is pivotable about an axis generally perpendicular to the longitudinal axis. The reamer is connected to the driver head.

Abstract: A new and improved reamer having a plurality of openings therein. Each of the openings have a periphery and a cutting edge selected from the periphery. Each of the cutting edges are bound by opposite portions of the periphery. The opposite portions are extended past the cutting edge in a direction opposite of the direction transverse of the cutting edge whereby the cutting edge may be shaped as desired independently of the shape of the periphery.

Abstract: An orthopaedic reamer for cutting bone includes a shaft and a head coupled with the shaft. The head includes a distal face with a plurality of cutting teeth. Each cutting tooth includes a hole extending through the head. At least a portion of each hole has a substantially round perimeter. A raised lip is positioned adjacent to and extends around at least part of the substantially round portion.

Abstract: A new and improved reamer having a plurality of openings therein. Each of the openings have a periphery and a cutting edge selected from the periphery. Each of the cutting edges are bound by opposite portions of the periphery. The opposite portions are extended past the cutting edge in a direction opposite of the direction transverse of the cutting edge whereby the cutting edge may be shaped as desired independently of the shape of the periphery.

Abstract: A new and improved tool driver having a shaft with a longitudinal axis and opposite ends, a boss is secured at one of the shaft ends by which the tool driver is connected to a rotary tool. A tool collet is secured to the other of the shaft ends by which the tool driver may be driven by a surgical hand piece having a chuck in which the collet may be positioned. The boss is equipped with a securing device of the bayonet type having a latch mechanism which holds the rotary tool on the boss coaxially of the driver during use. In a specific embodiment, the tool driver boss comprises a first partial boss secured to the shaft. A second partial boss having a bore extending therethrough is positioned on the shaft. A stop is positioned on the shaft and a spring is positioned on the shaft between the stop and the second partial boss. The spring urges the two partial bosses together.
