Abstract
A replicator is provided for precisely resecting bone into a desired shape of a pattern. A pattern holder and a bone holder are spaced apart from each other, and rotatably mounted to a cylindrical shaft for indexing through corresponding predetermined angular increments about two parallel axes, which are perpendicular to an axis of the cylindrical shaft. A linkage means connects a probe and cutting tool to a frame for allowing free movement of the probe and cutting tool with respect to the frame, in three dimensions, while maintaining end tips of the probe and cutting tool parallel to the axis of the shaft. The probe and cutting tool are moved to trace the tip of the probe over an exterior surface of the pattern while operating the cutting tool to cut contours of the pattern into the bone. The pattern and bone holders may be rotated with the cylindrical shaft about the axis of the cylindrical shaft. The pattern and bone holders are rotated through the corresponding angular increments about the two parallel axes and are rotated together about the axis of the cylindrical shaft, for presenting the pattern and bone to the probe and cutting tool for different angles of approach.
