Redefining Ureteroscopy: The Digital Advantage
For decades, urologists have relied on fiber-optic ureteroscopes. While effective, these instruments suffer from a fundamental flaw: the fragility of optical fibers. Over time, fibers break, leading to the notorious “honeycomb effect” (black dots) that obscures vision during critical lithotripsy procedures.
The Camjoy YJ-Series solves these challenges fundamentally by utilizing advanced Chip-on-Tip CMOS technology. We place the image sensor directly at the distal end of the scope. This means the image is digitized instantly inside the patient, bypassing the need for optical fibers entirely.
The result is a scope that offers permanent high-definition clarity, zero image degradation over time, and a robust design that withstands the rigors of daily sterilization and laser surgery.
Why Go Digital?
- ✔ Zero Fiber Breakage: No more black dots or costly fiber repairs.
- ✔ Permanent Clarity: Image quality remains consistent for years.
- ✔ Wide FOV: Panoramic 120°-130° view for faster navigation.
- ✔ Lightweight: Integrated cable replaces heavy camera heads.
Engineering Excellence & Technology
1. High-Definition CMOS Sensor
The integrated CMOS sensor offers high-pixel density directly at the tip. This provides superior contrast and color fidelity, essential for distinguishing between ureteral tumors, mucosal lesions, and stone fragments. Unlike fiber scopes where the image passes through thousands of glass strands, the YJ digital signal is lossless, delivering a true-to-life picture to the monitor.
2. Ergonomic “All-in-One” Handle
Traditional scopes require attaching a bulky, heavy camera head to the eyepiece, which creates an unbalanced weight distribution and strains the surgeon’s wrist. The Camjoy YJ-Series features an Integrated Digital Handle. The lightweight data cable connects directly to the processor, significantly reducing hand fatigue and improving maneuverability during delicate TUL procedures.
3. Sapphire Lens & Stainless Construction
Durability is key. The distal tip is sealed with a Sapphire Window, a material second only to diamond in hardness. This ensures exceptional resistance to laser scratches and thermal damage. The shaft is constructed from high-grade medical stainless steel, providing the necessary torque to navigate tight ureters without buckling.
