Principle of Swiss EMS gravel cleaning system

Swiss EMS lithotripsy adopts minimally invasive technology, and only needs to make an incision of about 1cm at the waist. It completely uses the natural cavity of human urinary tract to insert the device into the stone for treatment without surgery. For complex kidney calculi, it is only necessary to set up a chopstick-thick passage at the waist, and put the lithotripsy equipment in it, so the operation time is shorter.
