high voltage pulsed discharge lithotripsy three-dimensional electromagnetic field simulation software particles motion trajectories tensile stress electrohydraulic lithotripsy pressure force extracorporeal shock wave lithotripsy
In order to study the feasibility of high voltage pulse discharge for stone disintegration,the motion trajectories of particles in the process of high voltage pulse discharge are analyzed using three-dimensional electromagnetic field simulation software based on the theory of high voltage pulse discharge for rock fragmentation.The simulation results show that the high voltage pulse discharge lithotripsy overcomes tensile stress,and it is more effective than electrohydraulic lithotripsy that overcomes pressure force; the high-voltage pulse discharge lithotripsy contacts with stones directly,compared with extracorporeal shock wave lithotripsy,it has smaller damage to internal organs of human body and is safer.High voltage pulse discharge lithotripsy equipment mainly uses pulse transformers and corresponding steep circuits to obtain high voltage and steep pulse,so the circuit is simple,the manufacturing cost is low and the economy is good.
