Abstract: The milling instrumentation of this invention provides a milling guide connected to the femur for accommodating a milling device. The milling instrumentation includes an alignment guide which is used by the surgeon to set a femoral bracket or base on the medial and lateral sides of the exposed femur adjacent its distal end. Once the brackets are set, the alignment guide is removed and a milling guide is connected to the bases. The milling guide establishes a series of reference planes each including a slot. A powered milling device having a burr connected thereto is guided by the slots along the reference planes to accurately mill away a portion of the bone. The milling device includes a bobbin-shaped tip which positively engages the slots to ensure that the milling device is held substantially perpendicular to the reference planes of the milling guide.

A novel device includes a housing containing a drive and carrying a soft, flexible, resilient, tongue-shaped head on one end thereof, the head containing an arcuate shaft with a straight inner end connected to the drive, whereby the path of travel of the shaft during rotation defines an ellipsoid with a cone on the outer free end thereof.

Abstract: A Sensory Stimulation Apparatus is disclosed with 9 stimulator beam which fits across the forehead and contains a stimulator belt with stimulator elements such as fingers. A rotating lever on one side of the forehead pulls the stimulator belt across the forehead; a return spring on the other side of the forehead pulls the stimulator belt back across the forehead. The strip onto which the stimulator fingers are formed can be attached by a hook and loop fastener which permits the user to replace the finger strip and thereby change the configuration of the stimulator fingers. The amount of contact pressure may be changed by an adjustable strap which supports the apparatus from the head. A voltage control permits user to alter the speed of the stimulation action. The apparatus may be easily reconfigured to stimulate other body parts by altering the shape of the stimulator beam and modifying the support strap to support the apparatus.
