Description
Technical Field
[0001] The present invention relates to the technical field of cochlear implants, and particularly to a titanium alloy cochlear implant. Background Art
[0002] A cochlear implant is an electronic device used to treat severe to profound sensorineural hearing loss. For patients who cannot regain hearing through traditional hearing aids, cochlear implants offer the possibility of regaining sound perception. A cochlear implant system generally includes an external microphone, a processor, a battery, a transmitter, and a built-in receiver and electrode array. Its basic principle is to convert external sound signals into electrical signals, and then directly stimulate the auditory nerve in the cochlea through the electrode array, bypassing the damaged hair cells, so as to activate the auditory nerve and generate auditory perception.
[0003] Although cochlear implants can restore basic hearing perception, their sound quality is far from comparable to natural hearing. Cochlear implants directly stimulate the auditory nerve in the cochlea while bypassing the damaged hair cells in the cochlea. Therefore, the clarity and sound quality of the sound tend to be "mechanized" or "electronic". Many patients report that the sounds produced by cochlear implants lack natural sound quality, especially in complex speech recognition and music appreciation, and the sound quality is significantly unsatisfactory.
[0004] In a noisy environment, the performance of cochlear implants is relatively limited. Although modern cochlear implants already have certain noise filtering technologies, in an environment with multiple sound sources coexisting, the system is still difficult to effectively distinguish speech from background noise. For example, in environments such as restaurants and streets, patients often have difficulty clearly hearing conversations, especially when the noise level is high, this difficulty is particularly prominent.
[0005] The adaptation to cochlear implants usually requires a relatively long time process. After the initial implantation of a cochlear implant, patients need to undergo a period of rehabilitation training to get used to the sound signals transmitted by the new device. During this process, some patients may experience auditory fatigue, sound distortion, or pitch disorder. For some patients, especially older adults, the adaptation process to cochlear implants may be more difficult.
[0006] Although the design of cochlear implants is becoming increasingly refined, most devices still require external worn processors, microphones, and batteries. These external components may cause discomfort or trouble to users, especially problems such as weight and unaesthetic appearance that may occur during wearing. In addition, the waterproofness and durability of external devices are still challenges during use, and frequent device replacement and maintenance also affect the user experience of patients.
[0007] Although the success rate of cochlear implant surgery is relatively high, as an invasive surgery, there are still certain risks of complications. Problems such as infection, bleeding, or cochlear damage that may occur during the surgery, as well as the occurrence of device failures after the surgery, will affect the patient's recovery process. Some patients may experience discomfort symptoms such as headache, dizziness, and tinnitus after the surgery, and in extremely rare cases, the cochlear implant device may not effectively restore hearing. Although cochlear implant technology can help patients of different ages restore hearing to a certain extent, in some cases, older patients may not achieve the ideal effect. Especially in adult patients, cochlear implants usually cannot restore complete language comprehension ability because their auditory systems have changed significantly and the time of hearing loss is relatively long, resulting in weakened language processing ability of the brain. No solutions have been proposed for related technical problems. Summary of the Invention
