Abstract
The invention discloses a polar array of artificial cochlear implant pre-bent electrode, which comprises a colloid silica and a polar array pre-bent like a cochlea, wherein the polar array consists of an electrode ring and an electrode wire, and is packed with the colloid silica as a whole. The polar array of artificial cochlear implant pre-bent electrode is characterized in that a plurality of supporting sections are arranged on the colloid silica facing away from the polar array, and are connected with the colloid silica into a whole, slender through holes parallel to the polar array are arranged on the supporting sections, the through holes penetrate the supporting steel cores to straighten the pre-bent cochlea polar array. The polar array is simple in structure, compared with the prior art, brings great convenience to the implanting operation of the polar array of artificial cochlear implant pre-bent electrode, allows the electrode closer to the spiral ganglion cell of the cochlea so as to improve the language discernibility, is low in power consumption and ensures that the implanted electrode works normally in the human body for a long time.
Description
Technical field
The present invention relates to artificial organ and medical electric device thereof, specifically a kind of artificial cochlea pre-bent electrode array union.
Background technology
People's ear can be divided into external ear, middle ear and internal ear three parts.The main effect of external ear and middle ear be with external sound by tympanum and with it in succession 3 auditory ossicles conduct to internal ear.Internal ear is the Semen Glycines size approximately, and the likeness in form Crusta Limax claims cochlea again.Several ten thousand auditory perception cells---hair cell is arranged in the cochlea, and hair cell will convert electrochemical energy to from the acoustic energy (mechanical energy) that middle ear transmit and cause acous excitement, and the acoustic nerve excitement conducts to acoustic information cerebral cortex and produces audition with the form of electricity.Because the deafness that the inner ear hair cells pathological changes causes is a sensorineural deafness, does not still have effective Therapeutic Method at present.For in, the severe sensorineural deafness, adopt the sonifer voice emplifying to improve one's hearing usually.But then do not help much for the anacusia patient that does not have residual hearing.Studies show that the pathological changes of most anacusia patients mainly is positioned at the hair cell of internal ear, and mostly acoustic nerve is intact.The artificial cochlea utilizes the acoustic-electric transducer mount to replace the hair cell of loss of function in deaf person's cochlea, directly stimulates auditory nerve to make the deaf person produce audition.The artificial cochlea comprises that device outside (mainly comprising the speech processor) and body are implanted into device two parts, and the signal transmission that device outside and body are implanted between the device is finished by electromagnetic induction, is separated by for skin between the two, does not have lead to connect.In whole artificial cochlea system, body is implanted into the part that device is a most critical, and device outside has only the recovery that could realize audition by it, and electrod-array is that body is implanted into the of paramount importance ingredient of device.
At present used in the world artificial cochlea implanting device electrode array union mainly contains 2 kinds of versions, and a kind of is the straight electrode pole matrix, and another kind is the pre-bend electrode array connection because the structure difference of implant, so function aspects also each is variant.For normal cochlea structure, the spiral-shaped of straight electrode pole matrix and cochlea can not coincide preferably, because the elasticity of electrode self, whole pole matrix deflection cochlea periphery, cause the stimulating current diffusion, power consumption is big, influence effect of stimulation, and push cochlea inner tissue easily, cochlea is caused damage, and pre-bend electrode array connection initial condition is a helical form, it is more near the spiral ganglion cell of cochlea, stimulates more concentratedly, can improve the resolution capability of language, and power consumption is little, and shortcoming is that it directly inserts in the cochlea can not conveniently perform the operation the time.At present external like product has been considered the convenience of implant surgery, have and carry out when utilizing assistive device to help operation that electrode inserts, pre-buried support inner core in electrode array union is also arranged, extract the method that supports inner core out while inserting during operation, electrode array union is conveniently implanted.
Prior art is to adopt pre-buried support inner core in the electrode array union, it is in the silica gel dorsad of electrode array union packaging body, be provided with a same long cylindrical hole, reach the straight purpose of pre-bend electrode array connection by the support steel core that inserts in the cylindrical hole with electrode array union.Because the cylindrical hole that the support steel core will insert is long, very thin again, and most of operating process all to be in visual effect be not good state, do not see the concrete situation of insertion, make and support relatively difficulty of insertion process the easy bending of steel core and cause inserting failure, also puncture the packaging body silica gel of electrode array union easily, destroy the insulating coating between each electrode and influence result of use, use very inconvenient.
Summary of the invention
A kind of artificial cochlea pre-bent electrode array union of providing at the deficiencies in the prior art is provided, it adopts the structure of the pre-buried support inner core of segmentation, made things convenient for the operation of artificial cochlea pre-bent electrode array union to implant, make electrode more near the spiral ganglion cell of cochlea, stimulate more concentrated, the resolution capability of language improves greatly, good reliability, long service life.
The concrete technical scheme that realizes the object of the invention is: a kind of artificial cochlea pre-bent electrode array union, comprise colloidal silica and be pre-bent to the pole matrix of cochlea shape, pole matrix is made up of electrode retaining collar, wire electrode, it and colloidal silica are packaged into one, characteristics are that the colloidal silica of pole matrix dorsad is provided with several supporting sections, supporting section and colloidal silica are one, and supporting section is provided with the slightness hole parallel with pole matrix, penetrate the support steel core in the through hole and make the pole matrix that is pre-bent to the cochlea shape straight.
One end of described colloidal silica is provided with the termination of jack, and the other end is provided with subring.
Described support steel core is a finer wire, and the one end is provided with draw ring.
The present invention is simple in structure, the operation that compared with prior art greatly facilitates artificial cochlea pre-bent electrode array union is implanted, the reliability and the safety of implant all are greatly improved, make electrode more near the spiral ganglion cell of cochlea, improve the resolution capability of language, power consumption is little, guarantees implant electrode long-term operate as normal in human body.

The specific embodiment
The present invention compares with present support steel core integral built-in structure, can reduce at straight pole matrix 2 Process in, support the steel core 4 unexpected pole matrixes 2 that insert, avoid supporting the accident of 4 pairs of pole matrixes 2 of steel core Damage, support steel core 4 during insertion, most of operating process all is in can be the directly visual stage, Not only so that the action ratio that inserts is easier to, has reduced and supported the probability of steel core 4 bendings, and avoided The insulating coating of 4 pairs of pole matrixes 2 of support steel core damages.
