The Camjoy Integrated Ureteroscope Portfolio
Precision Engineering for Every Anatomy. From 4.5Fr Micro-Access to Heavy-Duty Lithotripsy.
Engineering Philosophy: The “Integrated Fiber” Revolution
In the evolving landscape of endourology, the demand for instruments that are both smaller in diameter and more durable is paradoxical. Traditional rod-lens systems offer clarity but are prone to lens fracture when flexed. The Camjoy Integrated Ureteroscope Series solves this engineering challenge by utilizing Fused Fiber Optic Technology.
Unlike traditional scopes where lenses are spaced with air gaps, our system densely packs thousands of high-resolution optical fibers directly into the stainless steel shaft. This construction method yields three critical advantages for the modern urologist:
- Semi-Rigid Flexibility: The shaft can withstand roughly 30° of flexion without image loss or structural damage, allowing it to navigate the natural curvature of the iliac vessels and ureteral orifices without buckling.
- Hyper-Slim Profiles: By eliminating bulky lens spacers, we reduce the outer diameter (OD) significantly. Our 4.5 Fr needle scopes can access anatomies previously reachable only by flexible scopes, but with the durability of a rigid instrument.
- Autoclave Resilience: The solid-state construction expands and contracts uniformly under heat, making the entire portfolio fully autoclavable at 134°C (273°F), ensuring compliance with the highest sterilization standards.
💡 Technical Insight: The “Tapered Shaft” Advantage
Every Camjoy ureteroscope features a “Step-Down” tapered design. For example, the JY4346A features an 8.0 Fr distal tip that gradually expands to a 9.8 Fr proximal shaft. This design allows the tip to act as a mechanical dilator, gently opening the ureteral orifice, while the thicker proximal shaft provides the torque and column strength needed to push through strictures or edema.
1. JY43 Series: The Universal Standard (430mm)
The JY43 Series is the backbone of any urology department. With a standard working length of 430mm, these instruments are designed to treat the vast majority of ureteral stones in adult male and female patients. Directly compatible with the Wolf 8700 Series, they offer a seamless transition for surgeons accustomed to German optics.
Key Models Breakdown:
| Model | Tip / Shaft | Channel | Wolf Equivalent | Clinical Focus |
|---|---|---|---|---|
| JY4330A | 4.5 Fr / 6.5 Fr | 3.0 Fr | 8701.534 | Difficult Access: Stenotic ureters where balloon dilation fails. |
| JY4337A | 6.0 Fr / 7.5 Fr | 4.0 Fr | 8702.534 | Routine Slim: Minimizes post-op edema and pain. |
| JY4338AD | 6.5 Fr / 8.5 Fr | Dual: 4.2+2.4 | 8708.534 | Dual Channel: Simultaneous laser & basket use. |
| JY4346A/AS | 8.0 Fr / 9.8 Fr | 5.0 Fr | 8705.402 | Workhorse: Best balance of durability and flow. |
| JY4350A | 9.5 Fr / 12 Fr | 6.0 Fr | 8703.534 | Heavy Duty: Massive irrigation for large stones. |
2. JY31 Series: Precision for Short Tracts (315mm)
Ergonomics play a vital role in surgical precision. When treating pediatric patients or adult females, a standard 430mm scope leaves nearly 15cm of “dead space” hanging outside the urethra. This “lever arm” amplifies hand tremors and reduces tactile feedback.
The JY31 Series (315mm) eliminates this issue. By shortening the shaft, we increase the structural stiffness (rigidity), making these the ideal tools for transmitting force when dilating a tight distal ureter in female patients.
| Model | Tip / Shaft | Channel | Application |
|---|---|---|---|
| JY3130A | 4.5 Fr / 6.5 Fr | 3.0 Fr | Pediatric Needle Scope: Ideal for school-age children. |
| JY3137A | 6.0 Fr / 7.5 Fr | 4.0 Fr | Adolescent / Female: Routine distal stones. |
| JY3146A | 8.0 Fr / 9.8 Fr | 5.0 Fr | Standard Female: High flow for rapid dusting. |
| JY3147A | 8.5 Fr / 11.5 Fr | 6.0 Fr | Robust Female: Max durability for tough cases. |
3. JY46 Series: Extended Reach (460mm)
Anatomical variations can be challenging. In tall male patients, or when accessing stones in the renal pelvis via a semi-rigid approach, standard scopes often fall short. The JY46 Series adds a critical 30mm of length compared to the standard model.
This series is particularly valuable for urologists who prefer semi-rigid ureteroscopy for upper ureteral stones (proximal ureter) to avoid the higher cost and fragility of flexible ureteroscopes.
| Model | Tip / Shaft | Channel | Special Feature |
|---|---|---|---|
| JY4630A | 4.8 Fr / 6.0 Fr | 3.0 Fr | Deep Access: Reaches high strictures in tall patients. |
| JY4634A | 6.0 Fr / 7.5 Fr | 4.0 Fr | Slim Reach: Minimal trauma for upper tract work. |
| JY4640A | 8.0 Fr / 9.8 Fr | 6.5 Fr | Max Channel: Unique large channel in a long shaft. |
4. JY12 & JY15 Series: Micro-PCNL & Neonatal
This specialty line represents the frontier of miniaturization. With working lengths of only 120mm and 150mm, these scopes are not just “short ureteroscopes”—they are precision instruments for specific high-stakes procedures.
Primary Clinical Roles:
- Neonatal Ureteroscopy: For infants where the ureter length is less than 10cm. The JY1230A (4.5Fr) allows for intervention without the risks associated with larger instruments.
- Micro-PCNL (Needle-Perc): These scopes are increasingly used for percutaneous nephrolithotomy (PCNL) through “Micro” sheaths (4.8Fr to 8Fr). The short shaft allows the surgeon to work comfortably near the patient’s flank, delivering laser energy directly to renal stones via a needle-sized puncture.
| Model | Length | Tip / Shaft | Application |
|---|---|---|---|
| JY1230A | 120 mm | 4.5 Fr / 6.5 Fr | Micro-PCNL / Neonate |
| JY1546A | 150 mm | 8.0 Fr / 9.8 Fr | Mini-PCNL (12Fr Sheath) |
Spotlight Technology: The Dual Channel Advantage
Among our portfolio, the JY4338AD (and its siblings) stands out for its Dual Channel Architecture. In standard single-channel lithotripsy, urologists face the “Retropulsion Dilemma”: as the laser fires, the stone is pushed backward up the ureter, potentially migrating into the kidney where it becomes harder to reach.
The Dual Channel system eliminates this.
Channel 1 (4.2 Fr): Deploys a Nitinol Stone Basket to grab and stabilize the stone.
Channel 2 (2.4 Fr): Deploys the Laser Fiber to fragment the stone while it is held fast.
This “Trap and Zap” technique significantly reduces operative time and prevents the need for flexible ureteroscopy conversion.
Frequently Asked Questions (FAQ)
Q: Are these instruments compatible with my existing light source?
A: Yes. All Camjoy scopes come with a universal adapter set, ensuring connection with Wolf, Storz, Olympus, and ACMI standard light cables.
Q: What is the warranty on the fiber optics?
A: We offer a standard 1-year warranty against manufacturing defects. The integrated fiber design is tested to withstand hundreds of autoclave cycles, provided that proper cooling protocols are followed (no rapid cooling/quenching).
Q: Can the 4.5Fr scopes be used with a basket?
A: The 4.5Fr scopes (JY4330A, JY1230A) have a 3.0Fr channel. This is optimized for laser fibers (200/270 micron). While ultra-fine 1.9Fr baskets exist, we generally recommend these scopes for “Dusting” techniques using laser only, relying on irrigation to clear the fine dust.
