A semi-rigid or rigid, plastic or metal tube that is cone-shaped (i.e., it tapers down from a standard instrument fitting size to a small opening) and is either hand-held and manually inserted, or fitted onto a compatible otoscope, and then inserted into the ear canal to create a channel for examination, suction, irrigation, or the insertion of another surgical device during an ear/nose/throat (ENT) procedure. It may be referred to as an ear cannula. This is a single-use device.
