Unet Gastro™ Stone Basket: Pioneering Sheathless Retrieval Technology

Hainwise Urology proudly presents the Unet Gastro™ Stone Basket — a groundbreaking advancement in stone retrieval technology designed specifically for gastrointestinal and biliary applications. This innovative sheathless system revolutionizes procedural efficiency and safety by eliminating the traditional outer sheath, enabling unparalleled flexibility, space optimization, and atraumatic erformance in endoscopic stone management.

Core Features & Technical Advantages

1.Patented Sheathless Design：

Utilizes the TTS baby scope accessory channel itself as the functional sheath for basket extension and retraction. This revolutionary design saves critical accessory channel space, accommodates simultaneous irrigation or instrument passage, and allows for smoother, more flexible endoscopic maneuverability during complex procedures.

2.Braided Nitinol Wire Basket Head：

Engineered with a super-flexible, braided nitinol construction that maintains exceptional opening strength and shape memory. The basket resists deformation even after multiple stone extraction cycles, ensuring consistent, reliable performance and reducing the need for basket replacement during prolonged procedures.

3.Advanced Tipless Design：

Features a seamless, welding-free basket head with no traditional end cap or joints. This eliminates the risk of leaving foreign body fragments behind and allows the basket to achieve full, unrestricted expansion. The rounded ball-shaped tip facilitates atraumatic passage through narrow accessory channels and enhances the ability to entrap proximally located stones with minimal tissue trauma.

Clinical Applications

• Biliary Stone Extraction
  

Ideal for retrieving common bile duct stones during ERCP procedures, with enhanced flexibility for navigating biliary anatomy.

• Pancreatic Duct Stone Management

Sheathless design and tipless construction allow safe and effective access to pancreatic ducts for stone clearance.

• Complex Gastrointestinal Lithiasis

Suitable for endoscopic removal of gastric, duodenal, or colonic stones where traditional basket systems face space or flexibility limitations.

• Pediatric & Narrow-Caliber Endoscopy

Ultra-slim profile and atraumatic design support safe use in pediatric patients or procedures requiring smaller-diameter scopes.

• Multi-Instrument Procedures

Preserves accessory channel space for simultaneous irrigation, laser fiber passage, or contrast injection during stone therapy.
