The flexible distal tip enables access to the renal pelvis and calyces. Simultaneous irrigation and suction facilitate stone clearance, improve stone-free rate, and reduce the risk of residual stone fragments.
Negative pressure reduces intrarenal pressure, lowers the risk of urosepsis, improves irrigation flow, and minimizes holmium laser-related thermal injury.
The inner surface of the sheath and dilator feature a special hydrophilic coating with a low friction coefficient (μ≤0.2), reducing trauma during placement.
Immediate removal of turbid fluid provides a clear surgical field and enhances procedural safety. Zebra guidewire and drainage bottle are available as optional accessories.

For the negative pressure ureteral access sheath, the straight port of the sheath connector serves as the instrument access channel, while the angled port allows fluid outflow or connection to a negative pressure suction system. The angled port of the Y-shaped connector can be used for drainage or connected to a suction device.

Flexible distal sheath tip allows smooth navigation into the renal pelvis and calyces.

Reinforced wire structure provides excellent compression resistance and kink resistance. The smooth outer surfaces of the access sheath and dilator facilitate easier insertion.

The unique locking mechanism on the dilator hub securely locks the dilator to the access sheath, enabling synchronized advancement of the sheath and dilator.

The PTFE inner layer facilitates smooth advancement and retrieval of instruments. The thin-wall design maximizes the inner lumen while maintaining a minimal outer diameter.

The dilator features a smooth, elongated tapered tip for gradual dilation and reduced tissue trauma. The shaft provides excellent radiopacity for clear visualization.
