Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of middle ear ventilation tube, in particular to a new ear ventilation tube of preventing falling off. BACKGROUND

[0002] Otorrhea is a kind of non-purulent inflammation of middle ear with the main features of tympanic cavity effusion and hearing loss. The incidence rate of children is higher, and it is one of the common causes of hearing loss in children. For the first diagnosis of adult otorrhea, especially in the acute phase of secretory otitis media, tympanic membrane puncture can be performed, which can be used as one of the diagnosis methods of otorrhea and can achieve the necessary treatment effect. When the tympanic membrane puncture cannot suck out the effusion, the tympanic membrane incision is performed. Because the tympanic membrane puncture and the tympanic membrane incision are traumatic and the children cannot cooperate, we rarely use it for children, and we usually choose another surgical method for children, that is, tube placement. Tube placement is to place a ventilation tube in the tympanic cavity through the tympanic membrane, so that the middle ear and the external auditory canal are directly connected, thereby improving the ventilation and drainage of the middle ear. At present, the ear microsurgery is used to make a small hole in the tympanic cavity with a surgical needle, and then the ventilation T-shaped tube is implanted into the tympanic membrane hole with a surgical forceps. The operation is performed in steps, and it is relatively complicated. Many countries clearly point out in the diagnosis and treatment guidelines for children's chronic otitis media that the ventilation tube should be placed for more than 12 months. For children with chronic otitis media after tympanic membrane tube placement, or children with chronic otitis media who may have recurrence, the tympanic membrane tube placement time should be more than 15 months or the ventilation tube should be naturally shed. However, long-term tympanic membrane tube placement can cause tympanic membrane tube blockage, otorrhea, tympanic membrane perforation, granulation hyperplasia, cholesteatoma and other complications. The shedding rate of the ventilation tube is 2.7%, and the ordinary one is 21%. Therefore, a new type of ventilation tube with reliable fixation and good tissue compatibility is needed.

[0003] Therefore, it is necessary to provide a new ear ventilation tube to solve the above problems. UTILITY MODEL CONTENT
