ABSTRACT:
Power assisted gripping structure and method comprising a surgeon's rongeur including two elongated relatively axially moveable members having at one end thereof structure for gripping, cutting or crushing material, handle means for manually moving the elongated members axially relative to each other, electrically actuated power assist cylinder structure connected between the elongated members for assisting in producing relative movement between the elongated members on actuation thereof and switch structure for actuating the power cylinders in multiple stages. In different modifications, the structure for gripping, cutting or crushing material may be a Kerrison or Leksell rongeur tip. Alternatively, the structure for gripping, cutting or crushing may be adjustable wrench, spreader, prier suction cup or lifter structure and the power assisted gripping structure may be used in industry such as in robotics as well as in medical applications. The method of the invention comprises the steps of power assisting actuation of a surgeon's rongeur or the like with electrically actuated power cylinders and actuating the cylinders in pulsed steps and in multiple stages.
