Lithotripsie ultrasonique pour la mini-perc et l'uretère.
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.
Une lithotripsie ultrasonique à haut rendement assure une évacuation rapide des calculs qui raccourcit la durée de fonctionnement.
Un large choix de sondes de lithotripsie ultrasonique est disponible pour les applications PCNL, mini-PCNL, urétéroscopique et cystoscopique.
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.
