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 bone. Kits comprising any of: a molded flexible sleeve for enclosing a suture, a retaining clip for preventing the suture from slipping out of the sleeve, a buttress-shaped bone anchor screw comprising a micropolished eyelet for receiving a suture, and a suture which may, or may not be pre-attached to the bone anchor screw, are disclosed. A collapsible, protective cover for a bone anchor screw is also disclosed.
