The Cottle Speculum (10mm to 8mm Taper, 55mm Blades) is a specialized surgical instrument used in ENT (ear, nose, and throat) procedures for nasal examination and surgery. The 10mm to 8mm taper refers to the design of 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 providing a comfortable fit for the patient.
