Description
Technical field
The present invention relates to a kind of adjustable round window excitation type actuator of pose, belong to auditory prosthesis technical field.
Background technique
Hearing impairment is one of most common disease in society, and according to the difference of micromechanism of damage, hearing impairment can divide again
For conductibility hearing impairment and phonosensitive nerve hearing impairment.As the continuous development conductibility hearing impairment of science generally can be with
It is treated by operation, but there are no preferable treatment sides under existing science and technology for phonosensitive nerve hearing impairment
Method mostly uses greatly hearing aid to improve hearing.But traditional hearing aid can only solve light to moderate sensory nerve hearing impairment；
It is inconvenient to wear；Output voice signal and the voice signal of ear canal feedback are easy to happen aliasing, the sound for experiencing patient finally
The shortcomings such as clarity of signal reduction.
The implanted hearing aid dress of mechanical excitation in view of the above-mentioned problems, home and abroad research institution and researcher begin one's study
It sets, these implanted auditory prosthesis compensate hearing impairment by its internal actuator mechanical excitation phonophore.Compared to biography
System hearing aid implanted auditory prosthesis, since using mechanical exciting, sound gain amplifier value is much larger than the acoustically-driven of hearing aid,
It can compensate for the hearing impairment of higher degree；In addition, implanted auditory prosthesis actuator is to implant, without being put into ear canal, keep away
The stifled ear problem for having exempted from traditional hearing aid, improves wearing comfort.But many patients are with phonosensitive nerve hearing impairment
While, it is also damaged with phonophore, so that traditional implanted auditory prosthesis actuator can not work.For this purpose, proposing in the world
The hearing compensation scheme of excitation cochlea round window.This scheme avoids auditory ossicular chain, therefore can effectively treat mixed deafness.But
Middle Ear Implant used in the existing clinical research for the compensation of round window exciting is all the SOUNDBRIDGE of MED-EL company, a
The non-expert conventional electromagnetic Middle Ear Implant for the design of round window exciting.Occur actuator make moved end cannot well with round window
Film fitting, and then actuator vibration transmitting is insufficient, weakens the transmission efficiency of hammer vibration energy, reduces the hearing of Middle Ear Implant
Compensation effect.It is not easy to adjust in addition, actuator makees moved end orientation, so that it can not be in the pose of best exciting round window, part
Exciting force flogs a dead horse, and cannot be optimal hearing compensation effect.Oscillator make initial pressure that moved end is contacted with round window membrane also without
Method adjusts as needed, and result of study shows that initial pressure appropriate will enhance the hearing compensation effect of high band, this is especially
Be conducive to phonosensitive nerve hearing compensation.Support construction is not arranged pointedly in actuator, is clinically fixed on circle using fascia
On window, support stiffness is too small, and result of study shows this hearing compensation effect that will weaken actuator.The presence of the above problem, greatly
Clinical effectiveness is affected greatly, biggish individual difference occurs after leading to clinic operation and practical compensation effect is lower than Theoretical Design value.
