Description
Technical Field
The invention relates to a cochlear implant, in particular to a cochlear implant.
Background
The artificial cochlea consists of an implanted body in the body and a sound processor outside the body. The external sound processor collects sound signals through a microphone, converts the sound signals into electric signals, transmits the electric signals to a receiving coil of the implanted body in vivo through a transmitting coil, transmits the received signals to a decoder part of the implanted body through the receiving coil, decodes the electric signals and converts the electric signals into corresponding electric pulse signals, and stimulates ganglion cells in a cochlea through an implanted electrode, so that auditory nerves are excited, sound information is transmitted to the brain, and the auditory sense is generated.
Signal transmission between the external sound processor and the implanted part is accomplished by electromagnetic induction, with the two separated by the skin and without a wire connection. The implant is the most critical part of the overall cochlear implant, and needs to work safely and reliably in the human body for a long time, and the external sound processor can only realize the function thereof through the implant. The receiving coil of the implanted body is an important component, the transmission of electric signals and energy is realized through the receiving coil, and the reliability of the receiving coil and the accurate positioning of the implanted body and the transmitting coil of the sound processor directly influence the safety and the effectiveness of the artificial cochlea.
In the current cochlear implant, the receiving coil of the implant is generally encapsulated and coated by silica gel, and compared with other materials, the silica gel has good softness and good biological safety, and the body feeling comfort of a patient is also good.
In the present artificial cochlea, because the magnetic pole adsorption affinity that needs to utilize the magnet between internal and external device fixes a position, so that internal and external device carries out information interaction and energy transmission, conventional implantation magnet mechanism, the method is firstly encapsulated a cake magnetic core in a thin-walled metal casing, the axial magnetizes, the advantage is that the location is accurate between the magnet, but because product size restriction, metal casing is general thinner, and the cake magnetic core usually has intensity low, rare earth magnets such as samarium cobalt or neodymium iron boron that the fragility is strong constitute, this kind of implantation magnet mechanism is when receiving external force impact, the implantation magnet is very easy because of receiving the impact force, take place the shell damage, the cracked condition of magnetic core. If the shell is damaged, the rare earth magnets without biosafety, such as samarium cobalt or neodymium iron boron, can be contacted with human tissues, thus threatening the health of human bodies. If the magnetic core is broken, the magnetic core and the in-vitro device can not carry out magnetic pole adsorption force positioning, so that the artificial cochlea can not work normally. The second method is to arrange a certain number of cylindrical magnetic cores into a thin-wall metal shell in an array mode, and the magnetic cores are magnetized in the radial direction, so that the defect of poor center positioning function is caused in the arrangement mode.
Besides the requirements of biological safety and mechanical strength, the implanted magnet also needs good fixing measures in a human body, if the implanted magnet displaces in the human body, firstly, the implanted magnet causes physiological damage to the human body, and secondly, the in-vivo and in-vitro devices cannot be effectively positioned, so that the cochlear implant cannot normally operate.
When the cochlear implant is used, an external transmitting coil needs to be frequently detached, the current cochlear implant magnet is only encapsulated in silica gel, and the implanted magnet is not effectively fixed, and in the process of removing the transmitting coil, because of different directions and angles,traditional cake shapeThe implanted magnet can be subjected to a certain torsional force, and in severe cases, the implanted magnet can generate micro displacement and drag muscle tissues of a human body, so that a patient feels uncomfortable.
