Abstract
A surgical hand drill for inserting orthopedic screws and for drilling holes in the fixing of fractures and bone grafts employing a pair of bushings at opposite ends of a double-helix spiral drive shaft to maintain concentricity of rotation when transferring a squeeze hand motion to a pistol grip handle to a rotating drive motion for the screw and for the twist drill, with a compression-type return spring to return the drive shaft to its quiescent position, while providing a tactile feel to the surgeon as to the success in setting the screw into the bone, or drilling a hole, and which includes a quick disconnect adapter for accepting orthopedic screw driver tips of square, hexagonal and/or cross-fit end shank or other configurations, or twist drills.
