Description
Technical Field
The utility model relates to a biomedicine bionics field especially relates to a split type artificial auditory implanting device and connection structure thereof.
Background
Auditory implantation is an effective hearing reconstruction method for severe or extremely severe sensorineural deafness in ears. Artificial auditory implants mainly include Cochlear Implant (CI) and Auditory Brainstem Implant (ABI). The artificial cochlea implant is suitable for deaf patients with normal cochlear nerve development and no obvious serious malformation of cochlear structures, and the auditory brainstem implant is suitable for patients unsuitable for artificial cochlea implant, such as non-developed cochlea, ossification cochlea, auditory nerve defect, neurofibromatosis type 2 and the like. Conventional hearing implant devices split an external part (speech processor, etc.) and an internal part, wherein the internal part includes a receiving processor implant and implanted electrodes.
Taking the cochlear implant as an example, the working principle is that sound is collected by a microphone part of an external machine, then the speech processor encodes the sound information into electrical information (the external part is above), the electrical information is transcutaneously transmitted into a receiving processor (the internal part is below) in vivo by a coil, and then the processed signals are transmitted to an implanted electrode (implanted in the cochlea), and the electrode stimulates the inner ear sound sensing tissue to generate auditory sense. The stimulation process of the artificial auditory brainstem electrode implantation is basically similar to that of the artificial cochlea, but the electrode implantation part is the cochlear nucleus of the brainstem.
Both cochlear implants and artificial auditory brainstem implants suffer from implant damage during actual use, particularly the portion of the receiving processor that is implanted in the body.
At present, more than 60 percent of domestic cochlear implants are children, and the implant of a receiving processor in the body is embedded in a subcutaneous shallow position behind the ear, so that the cochlear implant is easily affected by trauma, the damage of the implant is caused, and the use of the cochlear implant is affected. In this case, the whole body part including the receiving processor implant and the implanted electrode usually needs to be removed through surgery, but the electrode part implanted into the cochlea is still intact at this time, and the electrode is also surrounded by the surrounding connective tissue, so that fine sound-sensing tissue around the electrode is easy to be damaged when the electrode is removed, the electrode is prevented from being implanted again, and the hearing effect after the electrode is implanted again is influenced.
In addition, because the operation of implanting the artificial auditory brainstem is intracranial operation, the risk is much higher than that of implanting the artificial cochlea (middle ear and inner ear operation), craniotomy is needed, the brainstem is exposed, and the electrode plate is implanted. If the electrodes are affected by damage to the implant portion, craniotomy procedures need to be performed again at greater risk. In addition, although the probability of damage to the implant due to trauma is low in adult neurofibromatosis type 2 patients, the position of the electrode pad at the brain stem part may be displaced and the effect may be lost due to the influence of tumor compression, so that the subcutaneous implant at the back of the ear may be normal, but the electrode position needs to be adjusted and even replaced.
