In-vivo implanted ossiphone vibrating device

Abstract

The invention relates to an in-vivo implanted ossiphone vibrating device. The vibrator comprises a first vibrator, a second vibrator, leaf springs, leaf spring pressing plates, magnetic conductive plates, a coil framework, a coil, a magnet, a holder and a shell; the first vibrator is of a stepped structure and comprises a bottom cylinder, a first lug boss, a second lug boss and a top cylinder; the second vibrator and the magnet are assembled on the peripheral surface of the second lug boss; the first vibrator is arranged in the holder; a wire outlet is formed in a sidewall of the holder; the holder is of a structure open at both ends and counter bored holes are formed in the two ends; the leaf springs and the leaf spring pressing plates are glued on the counter bored holes, respectively; the coil framework is further assembled on the peripheral surface of the magnet; the coil is wound around the coil framework; the magnetic conductive plates are assembled on the two end faces of the coil framework; the shell comprises an upper cover, a lower cover and a fixed plate. The in-vivo implanted ossiphone vibrating device has the advantages of available high-frequency vibration, high vibration efficiency and large vibration amplitude.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a bone conduction hearing aid vibration device implanted in the body. Background technique [0002] There are two forms of sound transmission, air conduction and bone conduction, but the final place where the sound is heard is the auditory system of the inner ear. The following are two different transmission paths for sound. Human speech and the sound from TV and radio are transmitted to the external auditory canal by vibrating the surrounding air, and then transmitted to the middle ear through the tympanic membrane. The vibration will become stronger in the middle ear, and finally touch the cochlea floating in the lymphatic fluid. Auditory hair cells and auditory nerve, so that you can hear the sound. Bone conduction does not pass through the outer ear and middle ear, but converts the audio signal into a vibration signal, which is directly transmitted to the inner ear ...

AI Technical Summary

Problems solved by technology

[0009] The core part of the bone conduction hearing aid implanted in the body is the vibration device. The vibration device of the existing bone conduction hearing aid implanted in the body is a vibrating plate or a vibrating plate. The vibrating plate or vibrating plate vibrates in a changing magnetic field to make the skull vibrate, but there is The following disadvantages: 1. The amplitude of the vibrating plate or vibrating plate is small, the impact on the skull is small, the vibration is not obvious, and the vibration efficiency is low; 2. The vibrating plate or vibrating plate has low vibration frequency and is not suitable for high-frequency vibration; 3. The vibrating plate or vibrating plate is not suitable for high-frequency vibration; The vibration plate has a large vibration contact area, the impact force is not concentrated, and the sensitivity is low
