The Cottle Speculum (10mm to 8mm Taper, 35mm Blades) is a surgical instrument used in ENT (ear, nose, and throat) procedures, specifically for nasal examinations and surgeries. The 10mm to 8mm taper refers to the speculum’s blades, which gradually narrow from 10mm at the base to 8mm at the tip, allowing for precise retraction of the nasal tissues while maintaining control and minimizing trauma.
