Description

Technical Field

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

[0002] In the existing technology, 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, adhesion, incomplete expansion of the tympanic membrane, and long-term blockage of the Eustachian tube pharyngeal opening by secretions and bacterial infection causing swelling and adhesion of the Eustachian tube pharyngeal opening. There is currently no effective intervention method to restore the Eustachian tube function and enhance muscle activity function for 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 long-term placement of a middle ear ventilation tube in the tympanic membrane to regulate the middle ear ventilation disorder and discharge the secretions in the tympanic membrane cavity. Secretions, middle ear ventilation tube is also called tympanic membrane ventilation tube. The tympanic membrane ventilation tube commonly used on the market is dumbbell-shaped or T-shaped. This type of tympanic membrane ventilation tube has the following shortcomings: 1. The dumbbell-shaped structure makes one end of the ventilation tube have great resistance when implanted into the tympanic membrane incision, which makes implantation difficult. Forced and violent operation can easily cause damage to the tympanic membrane and inner ear, and even cause permanent hearing loss; 2. The T-shaped structure makes the surface of the ventilation tube smooth, which is difficult to clamp with instruments, and is difficult to operate in the narrow ear canal, especially when operated with one hand. It requires high technical skills of the surgeon, resulting in prolonged operation time; 3. The fixation effect is poor, and it is easy to fall off prematurely after implantation, resulting in poor surgical effect.

[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, and the tentacle is fixed to 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 both 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, and 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, this type of anti-clogging tympanic membrane ventilation tube has poor fixation effect and is prone to fall off prematurely after insertion, resulting in poor surgical results. In addition, it adopts an integrated structure, which is not convenient for the ventilation tube to be inserted. If any part of it is damaged, it will cause the entire tube to be scrapped, resulting in poor economic benefits. Utility Model Content
