JDPN-VA4 extracorporeal shock wave lithotripter with patented ultrasound localization, copper reflector and stepless energy control for kidney, ureter and bladder stones.
The JDPN-VA4 Extracorporeal Shock Wave Lithotripter is a safe and efficient solution for the non-invasive treatment of kidney, ureter and bladder stones, with single-session success rates of up to 98%. Featuring multiple national patents in wave source positioning — including under-table and side positioning — its flexible multi-angle shock wave incidence leaves no dead zone for stone localization. A patented ultrasound probe manipulator, tiltable reflector cylinder and stepless energy regulation deliver precise, comfortable treatment, while a Mitsubishi PLC control system and integrated table-console design keep operation simple and space-efficient.
