Problems solved by technology

However, some patients with skull base tumors still cannot obtain hearing after receiving ABI implantation, which may be related to long-term compression of the brainstem by the tumor or direct damage to the brainstem during surgery, resulting in functional damage to the cochlear nucleus

Abstract

The invention discloses an artificial auditory midbrain stimulator. The artificial auditory midbrain stimulator provided by the invention has the following obvious advantages and advantages: the volume of an external part is small, the weight is light, and the artificial auditory cerebellar stimulator is easy to wear by a patient; most electronic devices are in vitro, so that system hardware and software are easy to upgrade; energy is provided in vitro and transmitted into the implantation part through the coupling coil, the implantation part does not need a battery, the service life of the implantation part is prolonged, and the electrode array of the implantation part can better stimulate more brainstem volute nerve nucleus cells and hypothalamus central nuclei so as to obtain richer sound hearing perception.

Description

technical field [0001] The invention relates to the technical field of artificial auditory reconstruction, in particular to an artificial auditory midbrain stimulator. Background technique [0002] For severe or extremely severe deafness, cochlear implants are currently the only effective device to help deaf patients recover their hearing. However, many diseases such as neurofibromatosis type 2, traumatic auditory nerve avulsion, auditory nerve / cochlear hypoplasia or For diseases such as immaturity and cochlear ossification, it is difficult to ensure the integrity of the auditory nerve, so it is impossible to restore hearing through cochlear implants. Therefore, Auditory Brainstem Implant (ABI) technology is usually used to directly stimulate the brainstem cochlear nucleus by bypassing the damaged auditory nerve, so that patients can obtain hearing. However, some patients with skull base tumors still cannot obtain hearing after receiving ABI implantation, which may be relat...
