Abstract
An artificial cochlea to be implanted in human body is composed of the electrode arrays consisting of 22 Pt rings and 22 Pt-Ir wires connected respectively to the said Pt rings, a decoder, an implanted coil connected to input and output of said decoder, a magnet concentric with said coil, and magnetic casing.
Description
Technical field
The present invention relates to a kind of artificial cochlea device, relate in particular to the interplantation part of this artificial cochlea device.
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, the existing sonifer voice emplifying that adopts usually improves one's hearing.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.
Artificial cochlea device is implanted into device two parts by speech processor (device outside) and body and forms.Its operation principle is to utilize 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 signal transmission that speech processor 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 device, body is implanted into the part that device is a most critical, and the speech processor has only the recovery that could realize audition by it.Body is implanted into device and is electrod-array.At present used in the world cochlear implant has 16 road electrodes, and 22 road electrodes are arranged, and 24 road electrodes are also arranged, and project organization is inequality, thus function aspects also each is variant.Generally speaking they all provide and lead stimulation more, are that first is permanent implanted, do not need battery-powered and only obtain the electronic installation of energy from the device that wear the outside.
How designing a more perfect body, to be implanted into device be pendulum technical issues that need to address in face of the science and technology personnel.
Summary of the invention
The technical issues that need to address of the present invention have provided a kind of Menas for inner planting artificial cochlea, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:
The present invention includes: the electrode battle array is by 22 platinum rings that are arranged in order, form with 22 platinoiridita silks that 22 platinum rings link to each other respectively; Mutually insulated between described every counter electrode battle array; A decoder; The digital interface of described decoder is joined with 22 platinoiridita silks respectively; An interplantation coil that links to each other respectively with the input of decoder, output two ends; One and the concentric Magnet of interplantation coil are encapsulated in the Magnet shell of titanium material; Described decoder is encapsulated in the decoder shell of titanium material; The Magnet shell of described 22 platinoiridita silks, interplantation coil, titanium material and the decoder shell of titanium material are encapsulated in the medical silica-gel encapsulating shell.
Compared with prior art, the invention has the beneficial effects as follows: install the speech processor outward in conjunction with cochlear implant and use together, can help deafness patient to experience external sound, come back to the sound world.

The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment to the present invention describe in further detail (
By Fig. 1, Fig. 2, Fig. 3, Fig. 4 as seen: the present invention includes: the electrode battle array is by 22 platinum rings 1 that are arranged in order, form with 22 platinoiridita silks 2 that 22 platinum rings 1 link to each other respectively; Mutually insulated between described every counter electrode battle array; A decoder 3; The digital interface of described decoder 3 is joined with 22 platinoiridita silks 2 respectively; An interplantation coil 4 that links to each other respectively with the input of decoder, output two ends; One and interplantation coil 4 concentric Magnet 5 are encapsulated in the Magnet shell 7 of titanium material; Described decoder 3 is encapsulated in the decoder shell 6 of titanium material; The Magnet shell 7 of described 22 platinoiridita silks 2, interplantation coil 4, titanium material and the decoder shell 6 of titanium material are encapsulated in the medical silica-gel encapsulating shell 8;
Described 22 platinoiridita silks 2 can be straight lines or become coiled type to link to each other with decoder 3;
Described coiled type can be in 17～19 circle scopes.
Interplantation coil, decoder, Magnet are formed among the present invention, and its core is a decoder, and its core is a large scale integrated chip, is encapsulated in the can of titanium material.Magnet is the SmCo material, also is encapsulated in the can of titanium material, mainly plays the received signal positioning action.Because titanium material shell is tough and tensile, shock-resistant, be not easy to damage, skin so can effectively prevent the erosion of liquid to circuit, also can prevent that the material of the inside from leaking again with the medical silica-gel encapsulation.The platinum wire coiling of interplantation coil, outside with the medical silica-gel encapsulation, platinum itself has good physical stability.
The electrode part is formed mutually insulated by 22 platinum rings and 22 platinoiridita silks among the present invention.The platinum loop section implants by operation, and the other end is connected with decoder.C, built-in Magnet are the SmCo material, also are encapsulated in the can of titanium material
Except that the platinum ring was exposed, all with the medical silica-gel encapsulation, medical silica-gel had good biocompatibility, good stable physical performance among the present invention.
Present stage, in, the severe sensorineural deafness, the existing sonifer voice emplifying that adopts usually improves one's hearing.Sonifer can help the patient to promote a tin valve on certain degree, is the sensorineural deafness patient for the deafness that causes owing to the inner ear hair cells pathological changes still, and sonifer does not then have great help.Shaped design of the present invention meets people's in ear ear structure, is used in combination the present invention and cochlear implant and installs the speech processor outward, can replace the hair cell of loss of function in deaf person's cochlea, directly stimulates auditory nerve, effectively helps deafness patient to produce audition.
