摘要： A surgical hand drill for inserting orthopedic screws and for drilling holes in the fixing of fractures and bone grafts employs a pair of bearings (22, 28) at opposite ends of a double-helix spiral drive shaft (26) to maintain concentricity of rotation when transferring a squeeze hand motion from a pistol grip handle (50, 60) to a rotating drive motion for the screw and or the twist drill. A compression-type return spring (36) returns 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. A quick disconnect adaptor (180 is provided for accepting orthopedic screw driver tips of square, hexagonal and/or cross-fit end shank or other configurations, or twist drills.
