Rotary cutting tool destroys spinal nervous tissue in situ within animal cadaver

摘要

In a process to remove spinal nerve tissue from an animal cadaver, the spinal cord and surrounding tissue are first shredded and destroyed in-situ prior to their immediate or subsequent removal. Separation, shredding and removal of spinal tissue is effected with a cutting tool. Also claimed is a commensurate routing tool with a conical cutting head. The tool may alternatively use high-pressure water spray jets and rear face high pressure infinitely-variable speed drive jets. The penetration speed of the cutting head (21) is determined by the speed of roller (27) rotation.
