1, German Wolf lithotripter adopts double-layer piezoelectric technology, high energy, good focus, suitable for different hardness of stones, for the treatment of post-operative residual powder, can also be twice as effective. And Huikang extracorporeal shock wave lithotripter adopts single-layer piezoelectric technology, with small energy and poor effect.
2, the German Wolf brand lithotriptic machine has advanced C-arm, can be high-definition imaging, the urinary system and liver and gallbladder system of small stones, very hard stones can be seen clearly; the device adopts a fully automated dual-positioning system, X-ray and ultrasound joint dual-positioning, positioning more accurate. The device adopts a fully automated dual positioning system with X-ray and B-ultrasound for more accurate positioning, thus realizing "precise stone crushing" and simultaneous detection of negative and positive stones. And Huikang extracorporeal shock wave lithotripter does not have advanced C-arm, the technical content is not good.
