Abstract

The invention discloses an auditory brainstem stimulating electrode comprising oxidized graphene and a manufacturing method of the auditory brainstem stimulating electrode. The auditory brainstem stimulating electrode comprises a piece type loop electrode arranged on a stimulator, an annular loop electrode, an electrode wire and a stimulating electrode, wherein one end of the electrode wire is connected with the stimulator, and the other end of the electrode wire is connected with the stimulating electrode; the stimulating electrode comprises an oxidized graphene carrier, 19-24 electrode contact points, a first electrode fixing hole and a second electrode fixing hole, wherein the electrode contact points are arranged on the oxidized graphene carrier to be connected with the electrode wire; and the first electrode fixing hole and the second electrode fixing hole are respectively formed in two ends of the oxidized graphene carrier. According to the auditory brainstem stimulating electrode disclosed by the invention, the oxidized graphene carrier can better bear the function of an electrode carrier, and neuron cell differentiation is induced; the oxidized graphene carrier also has excellent bacterium resistance, so that the effect of better recovering auditory capacity is achieved.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to an auditory brainstem stimulating electrode containing graphene oxide. Background technique [0002] It is well known that patients with profound deafness can improve their hearing with a cochlear implant (CI). However, for those patients with damaged cochlear nerve or even complete loss of nerve function, the hearing cannot be improved by cochlear implants due to the lack of complete cochlear nerve function. Auditor brainstem electrode implantation (auditor brainstemplant, ABI) Designed for patients with cochlear nerve function. [0003] Auditory brainstem implantation means that after the electrodes are implanted in the cochlear nucleus of the brainstem, the acoustic signal is converted into an electrical signal through an external receiver to stimulate the cochlear nerve to form an auditory pathway. ABI is suitable for patients with neurofibromatosis type 2 (NF2), dyspnea tymp...
