The cochlea converts its sound waves into bioelectricity, which is transmitted to the cerebral cortex through the auditory nerve of the patient, where people can hear the sound. Cochlear implant needs to make a small incision 2-3 cm behind the ear and insert the electrode into the cochlea. Cochlea is an electrical signal, which is converted by an in vitro speech coding processor and directly implanted into an electrode system to stimulate nerves to restore or rebuild the hearing function of deaf people. Compared with the simple expanded sound of hearing aid, cochlear implant can bypass the inner ear injury and directly stimulate auditory nerve fibers, so that patients can recover their hearing.
For those who don't know the difference between hearing aid and cochlear implant, we say that hearing aid is like a speaker, while cochlear implant is like a small mechanical ear. Cochlear implant was the first one? Real artificial organs? It may involve chip, independent power supply, electrode design, processing technology, immune materials, battery control, language processing, acoustic envelope program and other technical difficulties. There are many other technical problems, such as waterproof performance and wearing methods.
If the patient is completely deaf in both ears, they will feel it immediately when a processor is lost in the cochlea, because if it is lost, they will lose their hearing immediately. Generally speaking, the loss of in vitro osteogenesis machine will not lead to craniotomy. As long as you reconfigure the external host and set the data, you can use it. But there are also some extreme cases that need replantation, and implants need replantation. So don't do strenuous exercise or have any obvious exercise during wearing, and wear it according to the doctor's advice.
