摘要： A drill sleeve, including: an outer sleeve with an internal collet at a distal end of the outer sleeve, a slot, and an inner opening; a handle connected to the outer sleeve; an inner sleeve with an inner opening configured to receive and guide a drill bit, wherein the inner sleeve is configured to slide inside the inner opening of the outer sleeve; a trigger; a connection member connected to trigger and the inner tube, wherein the connection member passes through the slot in the outer sleeve and a biasing member configured to apply a biasing force between the handle and the trigger wherein the biasing force drives the inner sleeve into the outer sleeve, wherein when a distal end of the inner sleeve engages the internal collet, the internal collet is configured to engage a screw hole in a bone plate, align the drill sleeve with a nominal axis of the screw hole, and secure the drill sleeve to the screw hole.
