A device for mounting an orthopedic bone cutting apparatus to facilitate accurate cuts in vivo

摘要

A slide bed device for mounting an orthopedic bone cutting device so as to provide a surgeon with three accurately controlled degrees of freedom of movement of the cutter thereby facilitating extremely accurate placement of the saw preparatory to making in vivo bone cuts. The cutting device (25) is slidably mounted (20) on a vertical stand (18) for movement in a vertical plane, and the vertical stand (18) is in turn mounted perpendicularly on two relatively movable horizontal slides (15,17) at right angles to each other. The horizontal slides (15,17) are mounted on a three point frame (6,11,12) arranged for rigid adjustable mounting on the bone to be cut in a plane parallel the longitudinal axis of the bone.
