Description

technical field [0001] The invention relates to the technical field of ear, nose and throat medical equipment, in particular to a medical device for tympanic membrane puncture and intratympanic injection. Background technique [0002] Secretory otitis media is an inflammatory disease of the middle ear characterized by tympanic effusion and hearing loss. The main cause of the disease is the obstruction of the Eustachian tube, and the secretions in the tympanic cavity cannot be drained to the pharynx, forming a tympanic effusion. Tympanic effusion is mostly a mixture of transudate, exudate, and exudate. Clearing the tympanic effusion is the key to the treatment of secretory otitis media. Myringocentesis is the most commonly used treatment for otitis media, and it is simple and easy to do. Among them, in the treatment of secretory otitis media, it is necessary to insert the needle for the second time to inject medicine after the conventional puncture, sometimes forming two h...
