ADDLER 4K 4 mm 30° Sinoscope with Sheath
Advanced Visualization for Functional Endoscopic Sinus Surgery
The ADDLER 4K 4 mm 30° Sinoscope with Sheath is a precision rigid endoscopic visualization system designed for ENT and Functional Endoscopic Sinus Surgery (FESS) procedures. Combining a 4 mm diameter, 30° viewing direction, high-resolution optical system, and compatible sheath, it provides clear visualization of the nasal cavity and paranasal sinus anatomy.
Designed for integration with modern 4K camera systems, the ADDLER Sinoscope supports high-resolution visualization with enhanced image detail, sharpness, contrast, and color reproduction. The 30° angled view provides the flexibility to visualize anatomical structures from different perspectives during minimally invasive ENT procedures.
