Surgical screw cartridge, screw holder/magazine and pistol-type screwdriver for bone fixation

摘要

An improved screw and apparatus for placing screws in a wire mesh and/or bone plate during an operation. In the preferred embodiment, the screw is self-tapping and the apparatus includes color-coded screw cartridges that mount directly onto the tip of a screwdriver and are held in place until installed in the proper location as dictated by the surgeon. The cartridge fits into a magazine that can feed the screw cartridges automatically into a screw gun that drives the screw into the proper location in the bone and the wire mesh or plate, or alternatively can be used with a manual screwdriver.
