The patented technology of Shanghai Jingcheng Medical Equipment Co., Ltd. is in China.

With the digital tracking rapid positioning technology with independent intellectual property rights and the original parallel positioning mechanism, as long as the stones are found by B-ultrasound, the distance between the stones and the surface of the B-ultrasound probe can be measured by using the ranging function of B-ultrasound machine, so that the shock wave source can automatically move to the stone position. It is fast and convenient, and can be adjusted accurately at any time, so as to greatly improve the hit rate of stone positioning, further improve the efficiency of lithotripsy, and also protect patients from additional injuries. This patented technology was successfully transplanted to the German Dornier import machine, creating a precedent for China people to transform imported medical equipment.
