A Fluid-Coupled Actuator Exciting a Round Window Membrane

Abstract

The invention discloses a fluid coupling actuator stimulating a round window membrane. The actuator comprises an expansion device and a vibration conduction device, wherein the internal space of the vibration conduction device is sealed and the sealed internal space is full of liquid or gas; the vibration conduction device comprises a top part and a tail part connected via a conduction pipe; the expansion device comprises a tail adjusting device, an expansion piece and a shell; the top part of the vibration conduction device is partially inserted into the shell of the expansion device, a top flexible membrane is pressed against the expansion, and a tail flexible membrane is pressed against the round window membrane of a patient. According to the fluid coupling actuator, the expansion device is used for generation original vibration transmitted to the round window membrane of the patient via the vibration conduction device, and thus audition of the patient is compensated.

Description

technical field [0001] The invention relates to a fluid coupling actuator for exciting the round window membrane, in particular to an implantable actuator for treating hearing loss which compensates for hearing loss by exciting the round window membrane, and belongs to the technical field of hearing aids. Background technique [0002] Hearing impairment is one of the most common diseases in society. According to the different mechanism of injury, hearing impairment can be divided into conductive hearing impairment and sensorineural hearing impairment. With the continuous development of science, conductive hearing loss can generally be treated by surgery, but there is no good treatment method for sensorineural hearing loss under the existing science and technology, and hearing aids are mostly used to improve hearing. However, traditional hearing aids can only solve mild to moderate sensorineural hearing impairment; it is inconvenient to wear; the output sound signal and the s...
