Description

Technical Field

[0001] The utility model relates to the technical field of tympanic membrane ventilation tubes, in particular to an anti-blocking tympanic membrane ventilation tube. Background Art

[0002] In the prior art, in secretory otitis media, especially refractory secretory otitis media after radiotherapy for head and neck tumors, symptoms recur repeatedly. Secretory otitis media caused by radiotherapy is caused by various reasons, such as Eustachian tube dysfunction, stenosis, adhesions. Tympanic membrane catheterization is suitable for exudative otitis media, middle ear effusion, bullous otitis media, etc., incomplete expansion of the tympanic membrane, and the pharyngeal opening of the Eustachian tube is blocked by secretions for a long time and bacterial infection causes swelling and adhesion of the pharyngeal opening of the Eustachian tube. There is currently no effective intervention method to restore the function of the Eustachian tube and enhance muscle activity function due to these irreversible injuries, so that the long-term symptoms of refractory secretory otitis media after radiotherapy cannot be alleviated. Therefore, it is still necessary to rely on the long-term placement of a middle ear ventilation tube in the tympanic membrane to adjust the middle ear ventilation disorder and discharge the secretions in the tympanic cavity. During the operation, a cutter is required to make an incision at an appropriate position of the tympanic membrane. The size of the incision is equivalent to the outer diameter of the ventilation and drainage tube. Tympanic membrane ventilation tubes are used in clinical practice such as myringotomy and catheterization. There are many types of tympanic membrane ventilation tubes used in myringotomy and catheterization. However, no matter which type of tympanic membrane ventilation tube is currently used, the fixation effect after installation is not very ideal, and the use effect is poor. In addition, in clinical practice, the outlet tube of the tympanic membrane ventilation tube is particularly thin, with an inner diameter of approximately 1.6-1.8 mm, and is easily blocked, which causes inconvenience to the clinic.

[0003] The Chinese utility model patent with application number: 202021310160.3 discloses an anti-clogging tympanic membrane ventilation tube, including an outlet tube and a tentacle, the outlet tube and the tentacle are fixed in a T-shape, the tentacle is fixed at the inner end of the outlet tube, and the inner end is the end extending into the patient's body; the tentacle is arranged in a strip shape, and its inner side surface is a groove surface, the groove surface includes a recessed area in the middle and convex areas on both sides, the recessed area and the convex area are arranged along the axial direction of the tentacle, and the recessed area extends to the end of the tentacle; the interior of the outlet tube is a hollow part, the hollow part is a diversion channel, the inner end of the hollow part passes through the tentacle until it is connected with the recessed area, so that the drainage channel is connected with the hollow part, and the inner end of the hollow part is exposed at the outer end of the outlet tube; a through hole is provided in the radial direction of the outlet tube. However, although this anti-clogging tympanic membrane ventilation tube can prevent the tympanic membrane ventilation tube from being blocked, it lacks an installation and positioning structure, resulting in poor stability after installation, easy displacement or falling off, and poor use effect.
