A receiving coil 3, a magnet block 2, and thick film circuit blocks 4a, 4b, and 4c are encapsulated in casings 1 and 9, and an active electrode 5 composed of twenty-four wire electrodes 7 and a ground electrode 6 extend out of the casing. After the electronic cochlea is implanted into a human body, a patient can hear various sounds within the frequency range of 20-20000Hz. The utility model releases the patients from the silent world and helps the patients return the world with sounds, so the utility model has great social benefits.
Description
This utility model relates to a kind of cochlear implant, belongs to the electronic installation that can make the dysacousis patient obtain audition.
Common deaf-aid set is to make the anaudia person below 130 decibels hear acoustical signal after sound is amplified, even but the use of the deafness patient more than 130 decibels sonifer also is of no avail.Cochlear implant then is subcutaneous with all being implanted behind the ear by the operation of made cochlear implant, and by the electrode excitation auditory nerve, is passed to nervus centralis face perceives sound signal under the cerebral cortex by auditory nerve again.Though leading three electrode cochlear implants, the vicarious three that the applicant and Xi'an Communications University, The People's Hospital succeeded in developing jointly in 1987 can make the dysacousis patient perceive a part of sound, but frequency range is narrower by (200～6000HZ), user debates to the acoustical signal that receives that rate is not low, and is also perfect not to the utmost.In addition, the cochlear implant volume in the artificial electronic ear of being made by Australia " mini system " (Mini System) is big, operation implants that back skin bulge is obvious, and peripheral nerve easily suffers oppression, and human body is easy to generate sense of discomfort, and is simultaneously also not attractive in appearance.Main is that its electrode is less, correspondingly stimulates the quantity of auditory nerve also few, and user can only be heard several different sound by it.Also have the electrode of this cochlea to adopt the continued access processing technique, difficulty is bigger, has also increased production cost simultaneously.It is reported this system at my domestic sales up to about 100,000 RMB, expense is very expensive, general patient and family can not accept at all, are not suitable for very much China's national situation.
The purpose of this utility model is exactly the deficiency of being mentioned in the above-mentioned background technology, and provide that a kind of volume is little, electrodeplate is many, frequency range broad and lower, the effective cochlear implant of expense.
Technical solution of the present utility model is such: this cochlear implant has a housing, receiving coil, thick film circuit block and magnetic piece all are positioned at housing, each strip electrode silk termination of active electrode is a ring shaped conductor and mutual insulating, and each strip electrode silk is connected to the band filter outfan of thick film circuit block.Said active electrode is made of 3～30 wire electrodes.Connect by lead between each thick film circuit block.Receiving coil, magnetic piece, thick film circuit block by nontoxic insulant embedding in housing.

Now in conjunction with the accompanying drawings this utility model is done a description.
As shown in Figure 1 and Figure 2, at belled housing 1 and housing 9 internal fixation receiving coil 3, magnetic piece 2 and thick film circuit block 4a, 4b, 4c are arranged, wherein, thick film circuit block 4a, 4b, 4C and magnetic piece 2 are positioned at the toroidal cavity that receiving coil 3 forms, and realize that by lead 8 circuit connects between thick film circuit block 4a, 4b, the 4c.Said magnetic piece 2, receiving coil 3 and thick film circuit block 4a, 4b, 4c are packaged in the belled housing 1,9 by nontoxic insulant such as Kynoar, have only the ground electrode 6 and the active electrode 5 that are connected with thick film circuit block to stretch out outside the housing 1,9.As shown in Figure 3, active electrode 5 is that 0.06 millimeter platinum electrode silk 7 is formed by 24 diameters, and the termination of every wire electrode 7 is a ring shaped conductor 10, and isolates by insulator 9 between the ring shaped conductor 10 of every wire electrode 7 and termination.It is two groups that 24 wire electrodes 7 are divided into, and is connected with the band filter outfan 11 of thick film circuit block 4a, 4b respectively.
Fig. 4 is the electrical schematic diagram of thick film circuit block 4a, 4b, 4c.In thick film circuit block 4c, comprise reception, amplification, filter shape, demodulation and amplified the shaping several sections.By the high-frequency modulation signal of external speech processes discharger emission through receiving coil 3 (L
1) receive to be coupled and come capacitor C

3Constitute a band filter, 24 band filters of same circuit and outfan 11 thereof are connected with 24 wire electrodes 7 in the active electrode 5 respectively.According to the needs of every wire electrode 7 output frequencies, can be according to the selected capacitor C of frequency
3Capacity parameter.
By the high-frequency modulation signal of external speech processes discharger emission through receiving coil 3 couplings, amplification, filter shape, demodulation and amplify shaping, convert whole tone signal frequently to, and in 15～20000HZ frequency range, be distributed into whole tone band communication number, conduct to the auditory nerve cilium that active electrode 5 and ring shaped conductor 10 stimulate different parts in the cochlea respectively by 24 wire electrodes 7 again.The motion by self under the excitation of the signal of telecommunication of auditory nerve cilium converts the electrical signal to the auditory nerve that kinetic energy is passed to cochlea, be sent to the brain nervus centralis by auditory nerve then, thereby make the deaf mute perceive the multiple sound of extraneous 20～20000HZ frequency range.
Adopt the thick film circuit of unitization in this cochlear implant, use miniature bonding die components and parts, printed resistor, high-frequency ceramic substrate, so volume is dwindled greatly, external diameter has only the 18-20 millimeter, and thickness is the 7-8 millimeter; Active electrode 5 adopts laser weld, and more many than having continued work simplification, its external diameter also has only the 0.6-0.8 millimeter.Said magnetic piece 2 is a rare earth permanent-magnetic material, because of it has higher magnetic field intensity, can with the magnetic piece adhesive better in the outer conveyer of ear, can be effectively the fixing position of conveyer.Also available paramagnetic material of magnetic piece 2 such as replacements such as iron plate, steel disc.
The utility model has overcome that volume is big in the background technology, frequency range is little, expense is high and active electrode adds Worker's difficulty is big to be waited not enoughly, possessed mainly that number of electrodes is many, frequency range greatly, small volume, cost be lower etc. excellent Point can replace the cochlea work of becoming deaf behind the Operation human body, make the severe Deaf and Hard of Hearing Talents hear 20～Muli-sounds in the 20000HZ frequency range frees them from the noiseless world, return to the sound world, Increase the confidence of its life, work, study aspects, reduce inferiority complex. In addition, since its volume little, take With low, implant subcutaneous rear external no obvious bulge, better appearance, general patient and family thereof all can receive, tool Great social benefit is arranged.
