[0002] Urinary stones are common diseases of the urinary system. Stones can be found in any part of the kidney, bladder, ureter and urethra, with kidney, ureter and bladder stones being more common. Currently, bladder stones or kidney stones are usually crushed by holmium laser lithotripsy or ballistic lithotripsy. During the lithotripsy process, the efficiency of natural stone removal is low, and the stone removal basket in the body requires repeated operations, which causes great damage to the body and takes a long time to operate. In order to solve the problems caused by stone removal in the body, negative pressure suction is currently used to remove stones.
