Trephining power tool attachment

Definition

A device intended to connect to a surgical power tool system motor [it is locked and held in a collet or quick coupling and not simply gripped in a drill chuck (Jacobs chuck)] to convert the non-dedicated mechanical energy provided by the motor to a dedicated mechanical motion to function as a craniotome when an appropriate cutter is inserted. It is inserted through a pre-drilled bur hole or perforator hole and is used to cut a flap in the bone of the skull vault (calvarium). It includes a small shielding tip at the distal end to prevent the end of the cutter penetrating the dura mater membrane. This is a reusable device.
