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.
