Dilator The dilator's diameter increased smoothly from 6Fr so as to provide gentle and gradual dilation. First-class Hydrophilic coating Lubricity is more durable without fragments, safer. Full coverage makes advancement easily The internal lumen is PTFE-lined and can facilitate the device's delivery and removal. Thin-wall design provides the largest possible internal lumen while minimizing the outer diameter. Prevent kinking design. The inter layer consists of a spiral steel wire construction to provide optional flexibility and maximum resistance to kinking and compression.

• Hydrophilic medical coating. • Flexible tip: The soft distal end can bend 30°-180°along with the flexible ureteroscope, allowing easy access to lower pole calyces. • Sheath moves in sync with the ureteroscope. • Works optimally in combination with flexible ureteroscopes. • Negative pressure suction function enables simultaneous laser lithotripsy and suction of powdered stone fragments. • Maintains appropriate negative pressure in the renal pelvis during surgery, avoiding increased pelvic pressure caused by prolonged fluid irrigation and reducing the risk of postoperative complications.
