Unet™ Stone Basket (Three-wire)

Unet™ Stone Basket (Three-wire): Precision Stone Retrieval for Modern Urology

As an innovative leader in specialized urological devices, Hainwise Urology presents the Unet™ Stone Basket (Three-wire)—an advanced stone retrieval system engineered for efficient, controlled, and safe removal of urinary calculi during endoscopic procedures. Our three-wire basket design offers superior maneuverability, enhanced visualization, and reliable stone entrapment in complex anatomical environments.

Core Design & Technical Advantages

The Unet™ Stone Basket (Three-wire) integrates precision engineering with clinically validated performance features:Unet™ Stone Basket

• Triple-Wire Basket Architecture:Three high-flexibility nitinol wires form a symmetrical, stable retrieval basket, providing optimal stone engagement while minimizing mucosal trauma and tissue snagging.

• Enhanced Stone Retention & Control:The unique three-wire configuration creates a balanced circumferential force distribution, ensuring secure stone capture and reducing the risk of fragment dislodgment during retrieval.

• 360° Rotational Steering Mechanism:1:1 torque response enables precise rotational alignment with the stone, facilitating targeted engagement in difficult-to-access calyces or tortuous ureteral segments.

• Low-Profile Sheath Design:Ultra-smooth, hydrophilic-coated delivery sheath (4.5Fr) allows effortless passage through flexible and rigid ureteroscopes, minimizing scope deflection and maintaining irrigation flow.

• High-Visibility Radiopaque Markers:Proximal and distal marker bands ensure clear fluoroscopic visualization of basket deployment, positioning, and stone entrapment throughout the procedure.

• Autoclavable & Single-Use Options:Available in both reusable (autoclavable) and sterile single-use configurations to match clinical preferences and hospital protocols.

Clinical Application Scenarios

The Unet™ Stone Basket (Three-wire) is an essential tool for urologists performing minimally invasive stone management:Unet&trade；

• Ureteroscopic Stone Extraction:Primary retrieval device for ureteral and renal stones during semi-rigid and flexible ureteroscopy (URS), especially effective for stones 5–15 mm in diameter.

• Basket-Assisted Stone Fragmentation:Facilitates stabilization of stones during laser lithotripsy by preventing fragment migration and enabling piece-by-piece extraction.

• Lower Pole Calculus Retrieval:Superior deflectability and rotational control allow effective access and stone engagement in challenging lower pole calyces.

• Stone Relocation Procedures:Enables controlled proximal migration of distal ureteral stones to the renal pelvis for more effective laser lithotripsy.

• Pediatric Ureteroscopy:Low-profile design and atraumatic wires make it suitable for pediatric stone cases requiring precise, gentle retrieval.

• Residual Fragment Clearance:Ideal for retrieving smaller residual fragments post-lithotripsy to achieve stone-free status.

Structure & Composition

• Basket head:Tipless design, braided nitinol wire, with super flexibility, the basket can maintain a good  shape during multiple retrieval of stones.

• Composite braided outer sheath:Enables smooth pushing, retraction and synchronous rotation of the basket under the extreme bending of  the scope.

• Tight closure:The basket closes tightly and is smoothly introduced for better treatment.

• Various models:Sheath out diameter options include.Fr, .Fr, .Fr.
