Abstract

The present invention relates to an intra-auditory stent for treating insufficiency of the auditory tube, and the intra-auditory stent for treating insufficiency of the auditory tube according to the present invention is characterized by comprising: a pressure control unit which closes the auditory tube and is opened and closed in accordance with the difference in pressure between the front and back so as to control the pressure in the auditory tube; and an auditory tube expansion part which is formed by being connected to the pressure control part, forms a through hollow through which a fluid moves in the front-rear direction of the auditory tube, is implanted in the auditory tube, and expands the auditory tube by deforming in the radial direction of the auditory tube.

Description

technical field [0001] The present invention relates to a stent implanted in Eustachian tube for treating insufficiency of Eustachian tube, in more detail, relates to a stent implanted in Eustachian tube for treating insufficiency of Eustachian tube which can treat stenosis or patency of Eustachian tube. Background technique [0002] Eustachian tube (Eustachian tube), also known as Eustachian tube, is a 3cm to 4cm long tube that starts below the inner space of the middle ear and extends to the nasopharynx at the back of the nasal cavity. The upper side of the tube is surrounded by narrow bone, and the lumen becomes wider and becomes cartilage down the side. There are tiny cilia inside, which help middle ear secretions to drain into the nasopharynx. Because children's eustachian tubes are horizontal and short, bacteria or viruses can easily enter the middle ear and cause infection. The length of the eustachian tube becomes longer and inclined as it grows, and mucus and fore...
