发明名称 Rotary cutter for external fixation pins
摘要 This invention provides for a pin cutter which forms an annular groove about the periphery of the pin. The cutter includes a cutting wheel that is rotated relative to the pin and is gradually tightened to force the cutting wheel into the pin and thereby widen the groove. The cutting action is similar to a pipe cutter used by plumbers to cut a length of copper tubing. The operator can continue tightening the cutting wheel against the pin until the pin is severed. A portion of the pin extends through the housing of the cutter. Since the pin is gradually cut, less force is required to sever the pin. Further, less force is released by the pin as it is severed. The severed and free portion of the pin is retained within the housing in a controlled manner.
