ABSTRACT:
An arthroscopic method for debulking tissue and a kit of arthroscopic tools for performing the steps of the method. A protruding piece of tissue that is bearing against a nerve is undermined by the formation of a cavity beneath it, and the cavity is collapsed by heat generated by a laser. When the cavity collapses, the protruding tissue falls into it and separates from the nerve. The kit includes plural dilator tubes that are used to progressively dilate the arthroscopic incision and plural cutter tubes that are used in sequence to cut larger and larger pieces of tissue. Plural forceps are employed to remove the cut tissue to form the cavity, and impactor members in the kit are used to compact the bone that surrounds the cavity just before the laser is introduced into the cavity to collapse it.
