Abstract

A motorized drill is mounted in the handle of a Kerrison Rongeur System utilized by a surgeon to perform surgical procedures on a patient, includes mechanism for moving the rotating drill toward the fixed upstanding foot mounted at the remote end of the pistol-shaped handle for removing bone which is located between the upstanding foot and the drill bit. In another embodiment, the drill is removably fixed in the handle and the foot moves relative to the drill bit. In either embodiment a trigger operated by the surgeon actuates the foot/drill and the trigger is biased to maximize the space between the foot and the drill bit. 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 performing the additional function of releasing the motor locked in position in the handle.
