Abstract: A universal arm has a proximal end, a distal end, and a middle portion therebetween. The middle portion has a plurality of interconnected ball and socket pieces. A plurality of clamps is selectively fixedly connected to the distal end of the universal arm by a connection that permits the selective rotation of each one of the plurality of clamps by 360° with respect to the distal end of the universal arm.

Abstract: A retractor ring assembly includes a ring holder that has a first selectively engaged connection and a second selectively engaged connection. A first and second ring portion each has a proximal end and a distal end. The proximal end of the first and second ring portions are selectively connected to the respective first and second selectively engaged connections of the ring holder. The distal end of the first ring portion has a third selectively engaged connection. The distal end of the second ring portion has a fourth selectively engaged connection. The third selectively engaged connection and the fourth selectively engaged connection are connectable to form a reinforced closed ring configuration, and are disconnectable to form an open ring configuration.

Abstract: A method and device for reattaching adjacent bone plates includes an inner seat, a pin, and an outer seat. The pin is fixedly connected to the inner seat. The outer seat is selectively connected to the pin so that adjacent bone plates are securely held in place between the inner seat and the outer seat. The outer seat includes a first outer seat and a second outer seat that are slidably connected together. The first outer seat has a slot. The second outer seat also has a slot. The first outer seat and the second outer seat are movable between a pin engaging position and a pin locking position.
