Description
Technical field
The present invention relates to a kind of artificial cochlea more particularly to a kind of artificial cochlear implants.
Background technique
Artificial cochlea is a kind of nerve electric stimulation device, is made of external machine and implant, clinically answers extensively
Treatment for severe and pole severe deafness.External machine picks up the voice signal of environment, is reconverted into the electric pulse by coding
Then signal stimulates the auditory nerve of cochlear axis to generate nerve impulse by implant, nerve impulse is along Auditory neuropathway in
Pivot transmitting generates the sense of hearing in auditory cortex.
The electrode of implant can be divided into intra-cochlear electrode and cochlea external electrode according to the difference of installation position.In cochlea
Although electrode is largely effective to the patient of severe and pole severe deafness, may cause mechanical damage, inflammation, foreign body reaction and
Secondary fibrosis and new bone formation.Therefore for some patientss, especially as in recent years be applied to have low frequency residual hearing
The development and application of the acoustoelectric combined stimulating technology of patient, cochlea external electrode are more suitable for, and cochlea external electrode can also effectively press down
Tinnitus processed is expected to be used for the treatment of tinnitus.
Summary of the invention
In view of the above drawbacks of the prior art, technical problem to be solved by the invention is to provide a kind of artificial cochlea plants
Enter body, electrode can be effectively placed in outside cochlea.
To achieve the above object, the present invention provides a kind of artificial cochlear implants comprising receiver, electrode, and its
A plurality of various sizes of locating pieces, wherein the electrode includes wire electrode, layer of silica gel and its contact, and the layer of silica gel is by the electrode
Silk wraps, which is fixed on the wire electrode, which is equipped with window on the contact position, which is equipped with not
With the groove of size, the size of the groove matches with the electrode contour dimension.
The electrode is in arc line shaped, which is located on the inside of the arc of the electrode.
The electro photoluminescence face of the contact is arc-shaped.Further, which is made of platinumiridio or platinum, equidistant to arrange.
Artificial cochlear implant of the present invention is by redesigning structure, so that electrode is effectively placed in outside cochlea, is applicable in
In different degrees of deafness patient, mechanical damage, inflammation, foreign body reaction and secondary fibre caused by electrode implantation cochlea can avoid
Dimensionization and new bone formation, it may also be used for the treatment of tinnitus.
It is described further below with reference to technical effect of the attached drawing to design of the invention, specific structure and generation, with
It is fully understood from the purpose of the present invention, feature and effect.

Specific embodiment
The invention will be further elaborated with reference to the accompanying drawing.
As shown in Figure 1, the present invention provides a kind of artificial cochlear implants comprising receiver 1, electrode 2, and its plural number
A locating piece 3, wherein encoded signal that the receiver 1 is sent for the outer machine of receiving body and by it handle after generate the electrode 2
Stimulated current, which is placed in outside cochlea, and for stimulating auditory nerve to generate the sense of hearing, the locating piece 3 is for fixing the electricity
Pole 2 is in outside cochlea, to guarantee the running of the electrode 2.
As shown in Fig. 2, the electrode 2 is in arc line shaped, to reduce bending stress comprising wire electrode (is not drawn) in figure, silicon
Glue-line 21 and its contact 22, wherein the layer of silica gel 21 wraps the wire electrode, and to protect the wire electrode, the contact 22 is fixed
In on the wire electrode, which is equipped with window on 22 position of contact, and the window is located on the inside of the arc of the electrode 2,
With the electro photoluminescence face of the exposure contact 22.
The contact 22 is made of the material of corrosion-resistant high biological safety, for example platinumiridio, platinum, quantity are preferably
6, equidistant to arrange, the electro photoluminescence face of the contact 22 is arc-shaped, to be bonded perimyelis.
As shown in figure 3, the locating piece 3 is equipped with groove 31, the size of the groove 31 matches with 2 contour dimension of electrode,
The electrode 2 is partially submerged into the groove 31.It has to be noted that the locating piece 3 is equipped with different sizes to adapt to ear
Different location outside snail is fixed, and similarly, which is also equipped with different sizes and is fixed with the different location for adapting to the electrode 2,
Doctor is enabled to select the suitable locating piece 3 according to real space.
As shown in figure 4, abrading sclerotin, shape to the outside of forward position cochlea foundation ring downwards from round window when 2 surgical installation of electrode
At appropriately sized groove, exposure perimyelis, the electrode 2 is placed in groove, in the electro photoluminescence of the contact 22 faces, along the electrode
2 gabarits dispose the locating piece 3 of multiple and different sizes, while the locating piece 3 and posterior tympanum or lower tympanum bone by the groove 31
Wall contact, to fix the electrode 2.
The preferred embodiment of the present invention has been described in detail above.It should be appreciated that those skilled in the art without
It needs creative work according to the present invention can conceive and makes many modifications and variations.Therefore, all technologies in the art
Personnel are available by logical analysis, reasoning, or a limited experiment on the basis of existing technology under this invention's idea
Technical solution, all should be within the scope of protection determined by the claims.
