Abstract

The invention provides an artificial cochlea microbend electrode, which comprises an electrode buffering section, an electrode transition section and an electrode cascading section sequentially connected via electrode wires, wherein the electrode buffering section and the electrode transition section are linear, the electrode cascading section are arc-shaped, the electrode cascading section is divided into two parts, one part is an elliptical electrode part close to the electrode transition section and formed by at least one elliptical ring electrode, and the other part is a semicircular electrode part formed by multiple semicircular electrodes in serial connection through pressing ring electrodes, the inner side of the electrode cascading section located in the semicircular electrode part is an exposed semicircular electrode, and the outer side of the electrode cascading section located in the semicircular electrode part is colloidal silica coating the semicircular electrode. The artificial cochlea microbend electrode is easy to insert and is used through combination between the semicircular electrode and the elliptical ring electrode, and effective electric stimulation is improved.

Description

technical field [0001] The invention relates to the technical field of artificial organ implantation devices, in particular to an artificial cochlear microbend electrode. Background technique [0002] A cochlear implant uses an acoustic-electric transducer to replace the dysfunctional hair cells in the cochlea of ​​the deaf, and directly stimulates the auditory nerve to enable the deaf to produce hearing. A cochlear implant consists of an external device (mainly including a speech processor) and an implanted device in the body. The signal transmission between the external device and the implanted device in the body is completed by electromagnetic induction. The two are separated by the skin and there is no wire connection. In the entire cochlear implant system, the implanted device in the body is the most critical part. Only through it can the external device realize the restoration of hearing. The electrode array is the most important part of the implanted device in the bod...
