The Camjoy JY4330A Ultra-Thin Fiber Semi-rigid Ureteroscope is engineered for the most delicate urological procedures. Designed as a direct alternative to the Wolf 8701.534, this instrument features an exceptionally slim 4.5 Fr distal tip and 5.5 Fr shaft, providing unprecedented access to narrow ureters and pediatric anatomies.
Utilizing advanced Integrated Fiber Technology, the JY4330A combines a high-density image bundle with a 3 Fr working channel, allowing for effective laser lithotripsy in spaces where standard ureteroscopes cannot reach.
4.5/6.5 Fr Profile
Needle-thin distal tip (4.5 Fr) allows for self-dilation and easy entry into tight ureteral orifices.
High-Density Fiber
State-of-the-art fiber optic bundle delivers bright, sharp images with 5° forward viewing angle.
3 Fr Working Channel
Optimized channel accepts laser fibers (230/270µm) and small Nitinol baskets for stone retrieval.
Semi-Rigid Durability
Integrated fiber construction resists breakage from bending, significantly increasing instrument lifespan.
Precision for Pediatric & Complex Urology
The “No-Dilation” Advantage
Routine balloon dilation can be traumatic and time-consuming. The JY4330A’s tapered 4.5 Fr tip facilitates atraumatic “primary ureteroscopy” even in non-dilated ureters. This is critical for pediatric lithotripsy and treating adults with ureteral strictures.
Wolf 8701.534 Compatibility
Manufactured to meet the exacting standards of the Wolf 8701.534 “Needle” series, the JY4330A offers:
- Compact Ergonomics: Lateral eyepiece design keeps the camera head clear of the instrument port.
- Optimal Flow: Despite the small diameter, the oval irrigation channel ensures sufficient flow for clear visualization.
- Universal Connection: Includes adapters for Wolf, Storz, and Olympus light cables.
