The Camjoy JY4346AS Standard Semi-Rigid Ureteroscope is the workhorse of endourology. Designed as a direct compatible model to the Wolf 8705.402, this instrument combines an 8.0 Fr distal tip with a reinforced 9.8 Fr shaft, making it the ideal “all-rounder” for treating ureteral stones in adult patients.
Featuring Integrated Fiber Technology, the JY4346AS offers exceptional image clarity with a 10° Wide Angle View, ensuring comprehensive visualization of the ureteral lumen and stone fragments.
Perfect Balance
8.0 Fr tip for easy insertion and 9.8 Fr shaft for durability. The standard choice for 80% of URS cases.
5 Fr Versatile Channel
Accommodates standard instruments (baskets, forceps) or dual 3Fr instruments, matching the Wolf 8705 spec.
10° Wide Angle
Expanded field of view compared to standard 5° scopes, aiding in faster stone location and navigation.
Durable Construction
Stainless steel tapered shaft resists bending torque during manipulation in tortuous ureters.
Reliability for Routine Lithotripsy
Optimized Design
The JY4346AS addresses the need for a single instrument that can handle routine and moderately complex cases. Its tapered design allows for gradual dilation of the ureteral orifice, while the 9.8 Fr proximal shaft provides the stiffness required to push through edema or minor strictures without buckling.
Wolf 8705.402 Compatibility
This model faithfully reproduces the performance characteristics of the Wolf 8705 series:
- Offset Eyepiece: Ergonomic 45° offset handle keeps the camera head clear, allowing straight instrument insertion.
- Large Capacity: The oval working channel supports 1x 5 Fr instrument or 2x 3 Fr instruments simultaneously.
- Universal Connectivity: Includes adapters for Wolf, Storz, and Olympus light cables.
