The Camjoy JY4338AD Dual Channel Ureteroscope redefines surgical efficiency. Engineered as a direct equivalent to the Wolf 8708.534, this advanced instrument features a slim 6.5/8.5 Fr profile while housing two independent working channels.
This unique configuration allows urologists to insert a laser fiber and a stone basket simultaneously, eliminating the time-consuming need to constantly swap instruments. It is the ultimate tool for complex lithotripsy and stone extraction.
Dual Working Channels
Channel 1 (4.2 Fr) for baskets/forceps + Channel 2 (2.4 Fr) for laser fibers. Work in parallel, not series.
Slim 6.5 Fr Tip
Tapered atraumatic tip design ensures easy insertion, matching the profile of standard single-channel scopes.
Simultaneous Action
Fragment a stone with the laser while holding it stable with a basket, preventing stone migration.
Continuous Irrigation
Use the second channel for high-flow irrigation when only one instrument is deployed.
Multitasking Power for Complex Stones
The Dual Channel Advantage
In standard ureteroscopy, stone migration (retropulsion) is a constant challenge. The JY4338AD solves this by allowing you to secure the stone with a Nitinol basket via the main channel (4.2 Fr) and pulverize it with a laser fiber via the secondary channel (2.4 Fr). This “Grab and Dust” technique significantly reduces operative time.
Wolf 8708.534 Compatibility
This instrument is manufactured to the precise specifications of the Wolf 8708 series:
- Optimized Ratio: Maintains a slim 8.5 Fr shaft diameter despite housing two channels and fiber optics.
- Lateral Eyepiece: Ergonomic offset handle separates the optical path from the two instrument ports for unhindered access.
- Durability: Reinforced stainless steel bridge separates the channels to prevent instrument cross-over or damage.
