Ring cutter method of ring removal

Use ring cutters with care in patients with lacerations because metal filings may cause foreign body reaction and/or chronic synovitis. Check the saw blade to ensure it is sharp and clean. Note that standard ring cutters are usually not effective for removing hardened steel rings (eg, steel nuts, washers). Place the guard of the ring cutter under the ring on the plamar aspect of the hand or plantar aspect of the foot. Apply the saw blade to the ring using the lever (large arrow) and turn the wheel of the blade using the handle (lines). Heat from friction may develop and necessitate periodic cooling with cold water or ice. Once the ring is cut, remove it from the finger by pulling it apart with hemostats. Two cuts may be necessary to permit removal.
