In vivo ultrasonic lithotripsy (referred to as ultrasonic lithotripsy) is widely used in stone therapy because of its safety and effectiveness.
Ultrasonic lithotripsy uses electrical energy to transform into sound waves. The sound waves generate mechanical vibration energy in the ultrasonic transducer, which is transmitted to the ultrasonic probe through the ultrasonic electrode to cause longitudinal vibration of the top end. When contact with the hard stone, the gravel effect is generated. But it does not cause damage to the soft tissue.
