Criterium Handle & Closing System

The KOBOT™ handle is custom engineered to offer urologists a comfortable grip and a highly responsive control system. An assisted closing mechanism is available on specific SKUs (ROSZ1940ST) to secure stone fragments.

Smooth opening and closing strokes reduce fatigue during complex lithotripsy procedures.

Flexi-Tip Deflection Technology

Standard baskets can limit the articulation of modern flexible endoscopes. The KOBOT™ features an improved Flexi-Tip junction.

This Flexi Tip Improvement provides a better scope deflection.
