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.
