Unet™ Stone Basket (Four-wire)

Unet™ Stone Basket (Four-wire): Advanced Multi-Wire Retrieval for Complex Calculi

Hainwise Urology presents the Unet™ Stone Basket (Four-wire), an evolution in stone management technology. Designed with an enhanced four-wire nitinol basket, this device offers superior stability and engagement for securing larger, irregular, or multiple calculi during demanding endoscopic procedures. It combines robust retrieval capability with exceptional trackability and one-handed control, addressing the nuanced needs of modern endourology.

Core Features & Technical Advantages

1. Secure Four-Wire Capture & Superior Flexibility

The four-wire nitinol basket provides a denser, more stable retrieval matrix for reliable engagement of complex calculi. Its super-flexible design allows the basket to fully restore its original shape even after multiple grasping cycles, ensuring consistent performance and procedural safety.

2. Enhanced Trackability in Tortuous Anatomy：

Featuring a slim, soft, and lubricated spring coil sheath, the device passes smoothly through the accessory channel of a ureteroscope, even at extreme angles. This design ensures minimal friction and reliable access to lower pole calyces or narrowed ureteral segments.

3. Intuitive One-Handed Operability：

The ergonomically designed handle integrates rotation and advancement functions, allowing the surgeon to smoothly rotate and push the device with one hand. This streamlined control improves surgical efficiency and reduces hand fatigue during prolonged procedures.

4. Fluoroscopic Visibility & Low-Trauma Design：

Radiopaque markers at the basket base and sheath tip provide clear visualization under imaging. Combined with a polished, atraumatic basket profile, the device supports precise positioning while minimizing mucosal injury during stone capture and retrieval.

Clinical Applications

1.Large or Impacted Ureteral Stones ： Provides secure grip and stability for extraction or laser lithotripsy.

2.Multiple or Irregularly Shaped Fragments ：The four-wire design enhances capture efficiency in post-laser fragment retrieval.

3.Lower Pole and Difficult Calyceal Access ：Excellent flexibility and trackability support navigation and stone engagement in challenging anatomy.

4.Basket-Assisted Laser Lithotripsy ：Stabilizes stones effectively during laser application with reliable shape retention.
