Abstract: A motorized drill is mounted in the handle (18) of a Kerrison Rongeur System utilized by a surgeon to perform surgical procedures on a patient, includes mechanism for moving the bit (25) supported in a rotating drill (12) toward the fixed upstanding foot (24) mounted at the remote end of the pistol-shaped handle (42) for removing bone which is located between the upstanding foot (24) and the drill bit (25). In another embodiment, the drill (133) is removably fixed in the handle (126) and the foot (120) moves relative to the drill bit (129). In either embodiment a trigger (22 or 124) operated by the surgeon actuates the foot (24 or 120)/drill (12 or 133) and the trigger (22 or 124) is biased to maximize the space between the foot (24 or 120) and the drill bit (25 or 129). The foot shape and dimension can be modified for perfecting given surgical procedures. In one embodiment the drill motor releasing mechanism includes a pinion gear and rack (72 and 84) performing the additional function of releasing the motor (12) locked in position in the handle (18).
