Surgical device and method for connection of fractured bones

摘要

A screwdriver for re-joining first and second pieces of a fractured bone in cooperation with a connector plate. A screw has an screw-shaped inner end for biting into the bone upon passing through a bore of the connector plate, and out of a hole in the first bone piece. The screwdriver includes a first shaft unit to engage and rotate the screw to move the screw axially, and a second shaft unit to rotate an axially movable sleeve. Axial movement of the first shaft unit moves the screw so that the outer end of the screw passes through the sleeve and into the second shaft unit such that the inner end of the screw protrudes inwardly from an inner end of the sleeve, whereby a threaded outer end of the sleeve is engaged with the bore of the connector plate before the screw is driven into the bone.
