The Camjoy JY4337A Ultrathin Semi-Rigid Ureteroscope is engineered for the most challenging endourological cases. Designed as a direct equivalent to the Wolf 8702.534, this instrument features a super-slim 6.0/7.5 Fr profile, making it the gold standard for pediatric urology and the treatment of adults with narrow or stenotic ureters.
Despite its compact diameter, the JY4337A incorporates advanced Integrated Fiber Technology to deliver high-resolution visualization while maintaining a functional working channel for laser lithotripsy.
6.0/7.5 Fr Profile
Tapered 6.0 Fr distal tip allows for atraumatic insertion without routine balloon dilation.
Integrated Fiber
Shock-resistant image fiber bundle ensures durability and consistent image quality during lithotripsy.
4 Fr Working Channel
Dedicated channel optimized for 230µm/270µm laser fibers and 1.9Fr stone baskets.
Pediatric Ready
The ideal instrument for pediatric lithotripsy and diagnostic ureteroscopy in narrow anatomy.
The Solution for Difficult Anatomy
Atraumatic Access
Routine ureteral dilation carries risks of perforation and stricture. The JY4337A minimizes these risks. Its 6.0 Fr tip acts as its own dilator, gliding easily through the ureteral orifice. This “No-Dilation” capability significantly reduces operative time and post-operative edema.
Wolf 8702.534 Compatibility
Manufactured to meet the rigorous standards of the Wolf 8702.534 Ultrathin series, the JY4337A offers:
- Offset Eyepiece: Keeps the camera head away from the instrument port, allowing straight access for laser fibers.
- Rigidity vs. Flexibility: The semi-rigid shaft provides enough torque for navigation while flexing slightly to accommodate ureteral curves.
- Universal Connectivity: Includes adapters for Wolf, Storz, and Olympus light cables.
