Abstract
Manual bone anchor placement devices include a lever, a force translator and a rotary force mechanism. The devices are substantially gun- or pistol-shaped and are actuated when a user squeezes the lever to the gripping portion of a handle. Manual, linear force on the lever is mechanically translated through the force translator to the rotary force mechanism, which transmits a rotary force to a securing element, or coupler, which mates with a bone anchor screw. The rotation of the securing element or coupler applies a torque on the bone anchor screw thereby placing the screw into the bone. A collapsible, protective cover for a bone anchor screw is also disclosed.
