Rigid otoscope is a medical device which is used to look into the ears. It is one kind of rigid endoscope. Health care providers use it to screen for illness during regular check-ups and also to investigate ear symptoms. It potentially gives a view of the ear canal and tympanic membrane or eardrum.
A typical dimesion of otoscope is 110mm length and 4mm diameter. We also have 2.7mm diameter version. The view angle could be 0°, 30° or 70°. There is one light incoming port at the side of otoscope, connecting to cold light source with fiber optical beam. The observation hole is at the base. When use, install the otoscope onto the endoscope camera head and connect the cold light source, then doctor is able to see the real time image on medical monitor.
A complete ENT surgery endoscope set contains otoscope, sinuscope and laryngoscope. The rest two endoscopes are in different length and diameter.
