Ultrasound lithotripsy for mini-perc and ureter.
When to use stand-alone ultrasound lithotripsy
Stand alone ultrasound lithotripsy for fast evacuation of softer – medium hard kidney stones through either standard or mini- percutaneous access or through semi-rigid ureteroscopes for ureteric stones.
High-performance ultrasonic lithotripsy for fast stone clearance shortens operating time.
A wide choice of ultrasonic lithotripsy probes is available for PCNL-, mini-PCNL-, ureteroscopic and cystoscopic application.
Ultrasound Working Principle
Piezoceramic elements: expand when connected to electricity.
Emits electricity when put under mechanical pressure.
This is called the piezoelectric effect.
This movement is transmitted onto the ultrasound probe and generates a very small longitudinal probe tip movement which creates an impact on a contact object (stone), leading to disintegration.
The ultrasound generator (control box) emits an electrical impulse to the piezo elements at a rate of approx. 25000 / Sec.
