Abstract

The invention discloses a graphene artificial cochlea electrode and a preparing method thereof. The electrode comprises a tip part, a bent part, contact electrodes, an electrode carrier and electrodewires, wherein the tip part is arranged at the foremost portion of the artificial cochlea electrode, the electrode carrier wraps the electrode wires and half wraps the contact electrodes connected with the electrode wires one to one, the bent part is an annular groove formed in the electrode carrier, each contact electrode comprises an inner side contact and an outer side contact, the inner side contact faces a worm shaft and the outer side contact backs to the worm shaft when the contact electrode is used and bent, and the electrode wires are wavy. The surface bioactivity of the contact electrodes is enhanced, the adhesion, proliferation and differentiation of cells are facilitated, meanwhile the formation and integration of peripheral nerves with the graphene artificial cochlea electrodeas the implant material are promoted, and the aim of improving the surface bioactivity and biocompatibility of the artificial cochlea contact electrodes is realized.

Description

technical field [0001] The invention relates to the field of electronic medicine, in particular to a graphene cochlear implant electrode and a manufacturing method thereof. Background technique [0002] In recent years, there has been a rapid development in the field of biomedical surface engineering research to develop new bioactive nanocoating materials as smart interfaces for cell research and regenerative medicine. The development of nanocoatings on biomaterial surfaces is a demanding field in tissue regeneration, from the level of signal transduction to macroscopic tissue reproduction. At present, the research focus in this field is mainly focused on enhancing surface biological activity, promoting cell adhesion, migration, proliferation and differentiation on the surface of biomaterials, and further enhancing tissue regeneration ability, and most importantly, it can be applied to actual clinical work go. Many scholars have demonstrated that cell shape, morphology, ad...
