Abstract: A surgical bone coring cutter is tubular in shape with the cutting end fabricated of a thicker section wall designed with both an inner and an outer cone. The double cone section causes the kerf to be wider than the wall thickness of the cutter shank, and the resulting clearance reduces friction and heat. Cutting element faces are at an essentially normal angle to the surface being cut and are supported by very long and relatively wide ramps of minimal relief angle. The ramps follow the cutting surfaces, carry off heat, and they prevent the cutter from digging in. The Cutter profile reduces tissue trauma and provides highly controlled advance of the cutter. The cutter is fabricated of several different materials; a hard material for sharpness and longevity of the cutting head and a resilient material for a shock resistant driving shank.

Abstract: A process with special instruments to Arthroscopically reduce certain joint fractures in humans and animals. The instruments are shaped and sized so as to afford remote manipulation of bone fragments, while viewing the procedure with an arthroscope and a fluoroscope in a C Arm. The process utilizes a lateral approach. This process with the instruments allows a skilled surgeon to affect an anatomically correct joint surface and then bone graft any bone deficit, all through small incisions local to the joint.

Abstract: A hand formable rod, band or sheet, consisting of a plurality of elements which are linked together in such a way that the whole can be either very flexible, or semi-rigid, or rigid. In the band, the elements have six degrees of freedom, providing unusual flexibility. This fabrication may be hand formed to a desired shape and then rigidified to a substantial stiffness. In the rigid state, this fabrication is strong enough to retract living tissue, and to perform as a mold, template, or fixator. The rigidity may be varied in very small increments by using a screw or screws acting upon tensioning cables. Tension causes increased friction between sliding surfaces. This friction creates stiffness and strength. Bending the fabrication does not cause material fatigue.
