  • Surgical instrument for cutting-out a cranial disc from the cranial bone

    Abstract: A surgical instrument is provided for cutting a cranial disc from a skull cap. A cylindrical trepanning cutter is provided with teeth on its frontal edge. The teeth cut in both peripheral directions. A driving means drives the trepanning cutter with a periodically altering direction of rotation through an angle of rotation of substantially less than 360.degree.. The angle is at least large enough for the teeth to be displaced by one tooth spacing along the frontal edge of the cylindrical trepanning cutter.
