Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a fitting tympanic membrane ventilation tube structure. Background Art

[0002] In the prior art, secretory otitis media is a common and frequently occurring disease among ear diseases. For patients with recurrent secretory otitis media, due to their poor Eustachian tube function, the tympanic cavity drainage is not smooth, resulting in negative pressure and (or) effusion in the tympanic cavity, which leads to hearing loss and even more serious sequelae such as adhesive otitis media. Tympanostomy tubes are often needed in the treatment of secretory otitis media. Surgical implantation of tympanic ventilation tubes is an important means to drain the effusion in the tympanic cavity, balance the pressure inside and outside the tympanic cavity, and improve tympanic ventilation. The T-shaped tympanic ventilation tubes used in hospitals in the past are safe due to their long tubes, but they are prone to tube blockage and are not easy to absorb the tympanic effusion after tube placement. If they are cut and used, they are easy to fall into the tympanic cavity and pose a safety hazard. The tympanic ventilation tubes currently available on the market can reduce the risk of tube falling off to a certain extent during use, but their insertion ends are usually symmetrical vertical structures, and the fit between them and the tympanic membrane is poor, resulting in low installation accuracy of the tympanic ventilation tubes, which is not conducive to postoperative wound healing.

[0003] The Chinese utility model patent with application number: 201720354672.1 discloses a tympanic membrane ventilation and drainage tube, which is characterized in that it includes: an outer plate and a spiral tube body, the outer plate and the spiral tube body are fixedly connected, the outer plate has a through hole, the spiral tube body has a hollow channel, the through hole of the outer plate is connected to the hollow channel of the spiral tube body, the outer surface of the spiral tube body has a spiral protrusion arranged around the central axis of the tube body, the left side of the outer plate is connected to the spiral tube body, the right side is provided with a sheet-like protrusion, the through hole of the outer plate passes through the left and right sides of the outer plate, and the free end of the spiral tube body is an oblique opening. However, although this type of tympanic membrane ventilation and drainage tube can reduce the incision on the tympanic membrane, it can only limit the tympanic membrane ventilation tube in one direction. If a large vibration occurs, the ventilation tube will fall off, and the fit between the tympanic membrane and the tympanic membrane is poor, resulting in low installation accuracy of the tympanic membrane ventilation tube, which is not conducive to postoperative wound healing.
