Abstract

The invention discloses an artificial auditory ossicle for treating a mixed hearing damage. The artificial auditory ossicle comprises a top tray, a connection bar, a piezoelectric device and a stapes clamp, wherein the top tray is fixed on an eardrum in an operation implantation manner; one end of the connection bar is connected with the top tray; the other end of the connection bar is connected with the base end of the piezoelectric device; the piezoelectric device mainly comprises piezoelectric stacks; the action end of the piezoelectric device is connected with the base end of the stapes clamp; and the action end of the stapes clamp directly acts on stapes. The artificial auditory ossicle not only can be used for replacing a damaged auditory ossicle like a traditional artificial auditory ossicle so as to treat a conductive hearing loss, but also has an active shock excitation ability so as to compensate an accompanied sensorineural hearing loss. In addition, the active auditory ossicle can work under the environment of high-intensity magnetic field and has the advantages of low energy consumption and good high-frequency gain. The artificial auditory ossicle also has the advantages of simple structure, high ireliability, low manufacturing cost and low price, thereby being convenient for widely popularization.

Description

technical field

[0001] The invention relates to an artificial ossicle, in particular to a piezoelectric active artificial ossicle suitable for treating hearing impairment and mixed hearing impairment. Background technique

[0002] The artificial ossicle is a device that replaces one or more of the three ossicles in the human middle ear, and is used to treat conductive hearing loss caused by necrosis or defect of the ossicles. However, it has been clinically shown that some of these patients with conductive hearing loss are also accompanied by sensorineural hearing loss, that is, the cochlea in the inner ear of the patient still has functional impairment. This combination of conductive hearing loss and sensorineural hearing loss is clinically called mixed hearing loss. For this type of hearing loss, the traditional treatment method is to implant the artificial ossicle, and then let the patient wear a hearing aid, that is, first treat the conductive hearing loss through the a...
