Graphene oxide artificial cochlea electrode and manufacturing method thereof

Abstract

The invention discloses a graphene oxide artificial cochlea electrode and a manufacturing method thereof. The graphene oxide artificial cochlea electrode comprises an electrode tip point, an electrodecarrier, an electrode contact point, a first positioning ring, a second positioning ring, a boosting part, an electrode wire, a loop electrode, a loop wire electrode and a wire array, wherein the electrode tip point is arranged at the front part of the artificial cochlea electrode; the electrode carrier is silica gel grafted with graphene oxide; the electrode carrier is used for packing the wireelectrode and semi-packing the electrode contact point in one-to-one connection with the wire electrode; the electrode carrier is entirely in the shape being micro-bending; and the wire electrode andthe electrode contact point are in one-to-one connection, and after passing the first positioning ring, the second positioning ring and the boosting part, the wire electrode is in the spiral shape. The methyl ethylene silica gel is adopted, after activating treatment, a silica gel coupling agent namely rrimethoxy silane is used for grafting the graphene oxide to the silica gel, and a hydrophilic antibacterial polymer is obtained, so that the hydrophilicity of the silica gel is improved, the silica gel has antibacterial properties, and besides, the cytotoxicity is reduced.

Description

technical field [0001] The invention relates to the field of electronic medicine, in particular to a graphene oxide cochlear implant electrode and a manufacturing method thereof. Background technique [0002] Medical silicone belongs to the group of organopolysiloxanes, which are formed by polymerization of monomers composed of silicon, oxygen and organic radicals. Medical silica gel has good physical and chemical stability and physiological inertia. After implanted in the human body, it will be absorbed, metabolized and degraded by the body. It has good aging resistance under complex environmental conditions in the body. These excellent characteristics of medical silica gel itself make it It is widely used in the field of biomedicine. Medical silicone began to be used in the medical field in the middle of the 20th century, and is now widely used in implant materials, such as artificial heart valves, urinary catheters, retinas and other organ or tissue substitutes.

Problems solved by technology

However, the antibacterial agents formed by commonly used antibacterial agents such as metal silver ions effectively prevent bacterial adhesion and proliferation, but also have potential dangers such as cytotoxicity, so their application is limited to a certain extent.
