The third generation EMS lithotripsy system is an all in one lithotripsy device that combines pneumatic ballistic, ultrasonic lithotripsy and negative pressure suction, which can remove the stone debris in time through the negative pressure suction system, significantly improving the efficiency of lithotripsy and shortening the operation time. At present, it has been applied to percutaneous nephrolithoscopy and ureteroscopic lithotripsy, which can shorten the operation time by more than half, and most of the patients can be completely cleared in one operation, which has brought gospel to the patients with urinary tract stones. Urolithiasis is a common and frequent disease in urology, which directly threatens people’s physical and mental health. With the continuous updating of lithotripsy means and the continuous development of endoluminal technology, almost all patients with urinary stones can be treated by endoluminal minimally invasive methods, but complex kidney stones, especially large stones, no matter what endoluminal methods are used (traditional pneumatic ballistics, laser lithotripsy, etc.), after stone crushing However, no matter what intracavitary methods are used (traditional pneumatic ballistics, laser lithotripsy, etc.), repeated flushing or clamping is required to remove the stones, which is not only inefficient, but also consumes a lot of valuable surgical time, and a considerable number of patients need staged and multiple operations to remove the stones, which brings heavy economic and mental burden to patients. The third generation EMS lithotripsy system can remove the stone debris by flushing while lithotripsy is being performed, ensuring a clear surgical field of view, greatly shortening the operation time, reducing bleeding and complications, saving patients’ surgical costs and alleviating their pain.
