A hand-held manual surgical instrument designed for the mechanical crushing of renal stones (calculi) in the urinary tract and/or bladder. It is typically designed with a sturdy pair of jaws at the distal end that are placed over and crush the stone when the operator applies pressure to the handles at the proximal end; the jaws close, grasp and crush the stone. Some types may employ a screw spindle which the operator can rotate to augment the crushing force. The instrument may be used endoscopically and may include a port for irrigation to provide a clear visual field. This device reflects old technology. This is a reusable device.
