Rigid Sinoscope 30° × 4 mm × 175 mm

The Rigid Sinoscope 30° × 4 mm × 175 mm is a reusable rigid optical ENT endoscope designed for clear visualization of the nasal cavity, paranasal sinuses and surrounding sinonasal structures during diagnostic nasal endoscopy and compatible surgical procedures. The 30° direction of view provides an angled perspective beyond the straight-ahead view of a 0° scope. The 4 mm diameter and 175 mm working length are a widely used adult configuration for ENT sinus endoscopy. Current manufacturer documentation identifies the 4 mm × 175 mm × 30° configuration as a common choice for functional endoscopic sinus surgery (FESS). The exact 30° × 4 mm × 175 mm configuration is also documented in the U.S. AccessGUDID medical-device database as a rigid optical sinoscope.
