Abstract
A device for resecting a bone utilizes a pattern to control the cutting tip for the resection. The device has a frame with a pattern holder and a bone holder. A tool holder mounts to the frame by means of a four bar linkage assembly. The tool holder has a cutting tool and a probe mounted to it. The four bar linkage allows three-dimensional movement of the tool holder, but constrains the tool holder to always be in parallel with a line extending through the pattern holder and bone holder.
