Swiss EMS lithotripsy system can be used for large size and high hardness stones, the ultrasonic lithotripsy system can significantly improve the lithotripsy, stone clearing efficiency, shorten the time of lithotripsy, reduce the rate of residual stone; for the renal accumulation of pus, infection, age, poor physical condition of the patient, the entire lithotripsy process does not need to take the stone extraction forceps or stone basket, and does not need to be repeatedly in and out of the uretero-nephroscope to flush, thus reducing the chance of surgical complications. This reduces the chance of surgical complications. Ultrasonic negative pressure adsorption removes blood clots and flocculent material affecting the field of view, making the field of view clearer; for small stones hidden in the calyx, they can be sucked out of the calyx through the ultrasonic adsorption function for treatment, improving the stone removal rate.
