Stone Retrieval Basket Type B Spiral, 1.00mm (3Fr) × 1200mm, Opening Width 10mm

I. Main Structure（主要结构）

Type A, Type E and Type F consist of basket cap, basket mesh, metal wires, outer sheath and operating handle. Type B, Type C and Type D are composed of basket mesh, metal wires, outer sheath and operating handle. The product is ethylene oxide sterilized, supplied sterile and intended for single use only.

II. Core Functions（核心功能）

- Endoscopic stone capturing and retrieval: Reach the target stone area through the working channel of ureteroscope, flexible ureteroscope or nephroscope. The basket opens automatically after being pushed out, captures and firmly clamps stones, and removes stones out of the body.

- Stone positioning during lithotripsy: Fix and adjust stone position during holmium laser lithotripsy to prevent stone retrograde migration into the renal pelvis. It enables segmented capture of broken stone fragments and improves overall stone clearance efficiency.

- Foreign body removal: Intended for grasping and removing residual indwelling catheters, exfoliated tissues and other intracavitary foreign bodies in the upper urinary tract.

- Auxiliary intraoperative exploration: Assist in detecting residual tiny stones in the ureter and renal pelvis during surgery.

III. Product Features（产品特点）

- Nitinol memory alloy wires: Deliver stable elastic resilience without deformation or fracture after repeated opening and closing. Ensure firm clamping and effective anti-slipping performance during stone retrieval.

- Multiple basket configurations: Available in diamond, spiral, lantern and semicircular shapes to adapt to different stone sizes and anatomical conditions. Headless design improves intraoperative safety and reduces mucosal injury risk.

- Complete slim outer diameter specifications: Covering 1.7Fr to 4.5Fr, compatible with working channels of various mainstream ureteroscopes and endoscopes.

- Flexible handle operation: Supports smooth push-pull movement and 360° free rotation for precise angle adjustment and accurate stone capturing.

- Flexible delivery sheath: Conforms to the tortuous physiological trajectory of the ureter, reducing friction and mechanical damage to urinary tract mucosa.

- Diversified opening sizes and lengths: Multiple opening widths of 8mm, 10mm, 11mm and 15mm together with various total length specifications meet surgical demands for ureteral, renal pelvic and calyceal procedures.
