Stone Fragmentation & Removal
Distal Chip-on-Tip HD Sensor: Direct digital imaging for exceptional clarity, brightness, and color accuracy (1080p).
Active 4-Way Deflection: High-degree, bi-directional tip deflection (often >270° up/down) for accessing lower pole calyces.
Integrated Design: Eliminates separate camera head, reducing setup time and potential points of failure.
Large Instrument Channel: Accommodates standard laser fibers (200µm/365µm), baskets, graspers, and biopsy tools.
Ergonomic Control Body: Intuitive lever for deflection and ports for irrigation/accessories.
High-Resolution Imaging: Reveals fine details of urothelium, stones, and tumors.
Durable Construction: Engineered for repeated sterilization cycles and clinical longevity.
Compatibility: Works with standard HD endoscopic light sources and video processors/monitors via digital (e.g., DVI/HDMI) connection.
Reduced Fogging: Often features integrated irrigation channels near the lens.
Essential for complex diagnostic and therapeutic upper urinary tract procedures: Diagnostic Flexible Ureteroscopy (URS), Ureteroscopic Lithotripsy (URS-L) for kidney/ureter stones (laser fragmentation), Treatment of Upper Tract Urothelial Carcinoma (Biopsy, Ablation), Ureteropelvic Junction (UPJ) Obstruction Assessment, Foreign Body Retrieval, Management of Strictures, and Calyceal Diverticulum Treatment. Its flexibility and image quality are critical for lower pole access and detailed mucosal inspection.
Q: What is "chip-on-tip" technology?
A: The image sensor is located at the very tip of the ureteroscope, capturing light directly for superior image quality compared to fiberoptic or lens-based systems.
Q: What deflection angle does it offer?
A: Typically >270 degrees in both directions, crucial for accessing the lower pole calyces in the kidney.
Q: What size laser fiber fits?
A: Standard 200µm and 365µm holmium laser fibers fit through the large instrument channel.
Q: How is it sterilized?
A: Designed for standard low-temperature sterilization methods like EtO gas or hydrogen peroxide plasma (check manufacturer specs).
Q: Does it require a special light source?
A: It requires a standard xenon or LED endoscopic light source connected via a light guide cable.
