The electrohydraulic effect crushing is a high-voltage and instantaneous pulse discharge in the liquid, and very high pressure is generated in the discharge area to crush the object. The ultrasonic crushing uses the impact force of ultrasonic high-frequency oscillation to crush materials. The thermal crushing is to heat the material and change ...

Many lithotripsy energy sources were first used for lithalopaxy, the crushing of bladder stones. Electrohydraulic lithotripsy (EHL), pneumatic lithotripsy (PL), and ultrasonic lithotripsy (USL) for the treatment of ureteral stones also predated the development of the ureteroscope and the practice of ureteroscopy. These lithotripsy …

In fuse explosion method, it is difficult to repeated explosions rapidly, as the fuse must be replaced before each explosion. Nevertheless, the fuse method boasts better energy utilization and crushing than the electrohydraulic method. Hence, these

In the first method (electrohydraulic fragmentation), the solid materials are immersed in a liquid medium (e.g., oil or water), which allows the plasma channel to expand rapidly, eventually producing powerful shock waves in the liquid medium. The shock wave front acts on the surface of the solid, crushing it by compressional forces [Fig. 1 (a)].
