    摘要： A screw driver (100) which comprises a motor (110) and a rotation transmission mechanism (120) is provided. The rotation transmission mechanism (120) comprises a driving gear (125), a spindle (150), a roller (141) and a retainer (130). The retainer (130) moves the roller (140) in a circumference direction of the spindle (150) and thereby a position of the roller (140) between a transmittable position and a non-transmittable position is switched.

    摘要： A hand-squeeze driver tool which serves to convert squeezing motion into rotary motion on a variable torque basis, with the torque being inversely related to the driving speed. The torque versus driving speed relationship is determined by the position of a squeeze lever (41) as it is displaced from its most extended position. Two distinct zones are provided as the squeeze lever is so displaced, namely a high torque low speed zone, and a low torque high speed zone. The provision of the high torque low speed initial zone, followed by the low torque high speed zone permits the operator intuitively to take advantage of the variable torque feature of the invention, which is provided by a traveling fulcrum which dwells at position F1 and F2 defined by sharp angles in levers (41,53).

    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.
