Ultraschall-Lithotripsie für Mini-Perc und 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.
Die hochleistungsfähige Ultraschall-Lithotripsie für eine schnelle Entfernung der Steine verkürzt die Operationszeit.
Für die PCNL-, Mini-PCNL-, Ureteroskopie und Urethrozystoskopie stehen zahlreiche Ultraschall-Lithotripsie-Sonden zur Auswahl.
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.
