Abstract
A high speed surgical instrument is designed with a clutch that automatically locks a cutter which is easily assembled and disassembled without moving parts. The clutch includes a pin and U-shaped pin that compliments a configured groove section at the proximal end of a cutter that fits into a clutch mechanism in the drill or attachment. The cutter includes axially spaced and opposed grooves judiciously located and a flat end portion that allows easy ingress and egress for locking into the clutch mechanism. A square or multi-sided bore configuration of a journal type bearing made from a high temperature resistance polymer material allows the drill to operate at high speeds with a reduction in the diameter of the distal end of the cutter support.
