Split type artificial auditory implant device and connecting structure of implant device

Abstract

The invention discloses a split type artificial auditory implant device and a connecting structure of the implant device. The split type connecting structure is used for connecting an electrode part and an implant of an in-vivo implant part in the artificial auditory implant device, wherein the split type connecting structure comprises an electrode connecting wire connecting port and an implant connecting port which are connected in a buckling mode; the electrode connecting wire connecting port is arranged at in tail end of an electrode connecting wire; and the implant connecting port is arranged in the implant. According to the artificial auditory implant device, the implant and the electrode part of the in-vivo implant part in the artificial auditory implant device are detachably connected in a split mode, and each of the damaged part of the electrode part and the damaged part of the implant can be replaced in a targeted mode, so that the in-vivo implant part is prevented from beingintegrally replaced; the artificial auditory implant device is suitable for artificial cochlear implantation, is also suitable for artificial auditory brainstem implantation, prevents the auditory ultramicro fine structure from being damaged when electrodes implanted into the cochlea, brainstem and other positions of the brain are taken out, reduces postoperative adverse reactions, and improves the auditory reconstruction effect of a patient.

Description

technical field [0001] The invention relates to the field of biomedical bionics, in particular to a split-type artificial hearing implantation device and a connecting structure of the implantation device. Background technique [0002] Auditory implantation is an effective hearing reconstruction method for severe or profound sensorineural deafness in both ears. Artificial hearing implants mainly include cochlear implants (CI) and auditory brainstem implants (ABI). Cochlear implantation is suitable for deaf patients with normal development of cochlear nerve and no obvious serious deformity of cochlear structure. Auditory brainstem implantation is suitable for cochlear underdevelopment, cochlear ossification, absence of auditory nerve, neurofibromatosis type 2, etc. Patients with cochlear implants. Traditional auditory implants are divided into an external part (speech processor, etc.) and an internal part, wherein the internal part includes a receiving processor implant and ...

AI Technical Summary

Problems solved by technology

[0005] At present, more than 60% of domestic cochlear implant recipients are children. Part of the receiving processor implant in the body is buried in the superficial position under the skin behind the ear, which is easily affected by trauma, resulting in damage to the implant and affecting the use of the cochlear implant.

In such cases, surgery is usually required to remove the entire body, including the receiver processor implant and the implanted electrodes, but often the part of the electrode implanted in the cochlea is still intact and the electrodes are also removed by the surrounding connective tissue. Surrounding, when taking out the electrode, it is easy to involve and damage the surrounding fine sensory tissue, and it will also hinder the re-implantation of the electrode and affect the hearing effect after re-implantation

[0006] In addition, because the brainstem implantation of artificial hearing is an intracranial operation, the risk is much greater than that of cochlear implantation (middle ear and inner ear surgery).

If the electrode is affected due to partial damage of the implant, it is necessary to take a higher risk of craniotomy again

In addition, for adult neurofibromatosis type 2 patients, although the probability of damage to the implant due to trauma is low, due to the impact of tumor compression, the position of the electrode pad in the brainstem may shift and the effect will fail. Therefore, sometimes the ear The subcutaneous implant is normal, but the electrode position needs to be adjusted or even replaced
