artificial tympanum

Abstract

An artificial tympanum is provided, which includes a support body and an elastic body, the elastic body can vibrate under the action of sound waves, the elastic body is used to support the artificial ossicle, and the support body is used to be placed in the tympanic cavity and support The elastic body is fixed at a corresponding position, the supporting body is fixedly connected with the elastic body, and the elastic body supports the artificial ossicle in the specific direction. The artificial tympanic cavity provided by the present disclosure can be used for the loss of eustachian tube function and the tympanic cavity is occupied by scar tissue. The artificial tympanic cavity can be implanted into the tympanic cavity that cannot reconstruct the air-containing cavity, occupying the entire tympanic cavity, and the support body can prevent the tympanic cavity from sticking and occupying the tympanic cavity , to prevent the scar from filling the entire tympanic cavity. The artificial tympanic cavity is composed of the support body and the elastic body to replace the original tympanic cavity, and the combination of the elastic body and the artificial ossicle replaces the tympanic membrane and the human body's own ossicle chain to complete the transmission of sound to the inner ear.

Description

technical field [0001] The invention relates to the field of medical instruments, and in particular to an artificial tympanum. Background technique [0002] Patients with chronic otitis media or other middle ear lesions destroy the necessary conditions for sound transmission such as the tympanic membrane, ossicular chain, tympanic mucosa, and Eustachian tube, resulting in conductive hearing loss. Reconstruction of the ossicular chain is a good way to help these patients restore their hearing. However, due to lesions, the tympanic membrane, ossicular chain, tympanic mucosa, eustachian tube and other necessary conditions for sound conduction are often destroyed, the tympanic membrane is invaginated and even the tympanic cavity is adhered, and a functional air-containing cavity in the tympanic cavity cannot be formed, so the Ossicular chain reconstruction technology helps patients improve their hearing. Although these patients choose ear canal or bone conduction hearing aids ...

AI Technical Summary

Problems solved by technology

However, due to lesions, the tympanic membrane, ossicular chain, tympanic mucosa, eustachian tube and other necessary conditions for sound conduction are often destroyed, the tympanic membrane is invaginated and even the tympanic cavity is adhered, and a functional air-containing cavity in the tympanic cavity cannot be formed, so the Ossicular chain reconstruction technology helps patients improve hearing

Although these patients choose ear canal or bone conduction hearing aids to improve their hearing, neither can restore the sound wave conduction that is closest to physiological conditions

Moreover, the price of bone conduction hearing aids is relatively high, and its external parts affect the appearance of patients, and MRI examinations cannot be accepted after implantation

[0003] For patients with eustachian tube dysfunction, tympanic adhesions, etc. that cannot form an air-containing tympanic cavity, a considerable number of patients have normal cochlear function, but due to surgical resection of the ossicles and tympanic membrane, the air conduction hearing is destroyed, that is, through the ossicular chain, The function of the tympanic membrane conduction is disrupted
