Ultra-Efficient Kidney Stone Fragment Removal via Spinner-Induced Synergistic Circulation and Spiral Flow
Main content start
A novel spinner device that enables ultra-efficient fragment removal through spinning-induced localized suction is introduced. It generates spiral and circulating flows to capture fragments from over 20 mm away, eliminating the need to chase them. This technology markedly improves procedural efficiency by reducing operative time, increasing stone-free rates, and minimizing the number of ureteroscope passes.
