Abstract

The invention relates to an auxiliary implantation device of a high-flux flexible electrode and an assembling method, and the auxiliary implantation device is used for assisting the flexible electrode to be inserted into the brain of an organism, and comprises a plurality of tungsten filaments which are used for fixing exposed electrodes of the flexible electrode in a one-to-one correspondence manner; the two-photon mold is a mold which is formed through two-photon printing and is provided with a plurality of opening grooves which are arranged in parallel at equal intervals, the opening grooves are used for placing tungsten filaments, and the distance between the opening grooves is equal to the distance between the exposed electrodes of the flexible electrode; the width of the opening groove is matched with the width of the tungsten filament, and the length of the opening groove is smaller than that of the tungsten filament. By arranging the two-photon mold, the tungsten filaments can be distributed on the two-photon mold in parallel at equal intervals, the flexible electrodes can be conveniently fixed to the tungsten filaments at equal intervals, and the implanting effect of the flexible electrodes is effectively guaranteed; the problem that in the prior art, due to the fact that tungsten filaments are not parallel or the intervals are not equal, the implanting effect is affected is solved.

Description

technical field [0001] The invention relates to the technical field of brain function detection, in particular to an auxiliary implantation device and an assembly method of a high-throughput flexible electrode. Background technique [0002] Neuro-electrophysiological monitoring plays an irreplaceable role in brain science research and brain disease diagnosis. High-quality neuro-electrophysiological signal acquisition technology is the basis for the smooth development of basic research on brain science and clinical research on brain diseases in China. [0003] The method of collecting neurophysiological signals mainly depends on the brain-computer interface. According to the way of information collection, it is usually divided into two types: implantable and non-implantable. Among them, non-implantable electrodes generally refer to EEG, which can Non-invasively observe and record brain activity, usually in the form of an electrode cap, by collecting and recording signals from...
