Abstract

The invention relates to the field of ear-nose-throat endoscopes, in particular to a multichannel invasive ear-nose-throat endoscope. According to the multichannel invasive ear-nose-throat endoscope, the ear, nose and throat positions can be photographed, when the annular air bag outside the outer tube is expanded by pressurized air, the annular air bag can provide anti-shaking support for the miniature lens module in the outer tube in the respiratory tract, photographing effect of the miniature lens module is improved, the miniature lens module can extend into the inner depth of the external auditory canal of a patient to perform photographing operation after being outwards connected with the switching module, the applicable scene and the use effect of the ear-nose-throat endoscope are improved, and in addition, medical staff and patients can control the size of the annular air bag according to practical conditions, so that the use safety of the ear-nose-throat endoscope is improved. The technical problem that the size of the ear-nose-throat endoscope suitable for the external auditory meatus is far smaller than the inner diameter of the throat respiratory tract, so that the ear-nose-throat endoscope can shake in a redundant shooting mode is solved.
