ABSTRACT:
The tool of the present invention comprises a stem. Cutting teeth extend outward from the stem. The stem has a central, longitudinal passage, connects to a suction or evacuation line. An outlet of the passage is at or near the cutting site. As material is cut, the suction carries the material to the central passage where it is evacuated. In one embodiment, each tooth has a cutting edge and a back side. One or more tubes connect the central passage to the back side of the cutting teeth. Suction from the central passage acts on the tubes to create suction at the cutting site. In another embodiment, the central passage is open at the distal end of the tool. Suction at the distal end cut material toward the distal end of the tool and into the central passage where it is evacuated from the tool.
