Abstract

A net-shaped cerebral cortical electrode includes an insulating substrate, a plurality of electrodes embedded in the insulating substrate, electrode wires embedded in the insulating substrate, electrode sleeve pipes for collecting the electrode wires and filling material areas located in hollow regions of the insulating substrate, and the insulating substrate has a net structure. Through the improvement, the discharge efficiency of a tissue fluid between the electrode and brain tissue can be improved, the adherence of the electrode on the surface of the brain tissue can be improved, and the monitoring quality of brain electrical signals can be improved.

Description

technical field [0001] The invention relates to an electrode for sensing and recording intracranial bioelectrical signals, in particular to a mesh intracranial cortical electrode. Background technique [0002] Under normal circumstances, the human brain produces weak bioelectrical signals on the surface of its cortex with certain regularity. When there are pathological lesions in the brain, the discharge pattern of the EEG signal will change significantly, and some lesions will cause special changes in the discharge pattern of the brain electrical signal. Clinically, by observing the special changes in these discharge patterns, the human brain can be affected. disease diagnosis and treatment. Currently the most common case of brain disease diagnosed and treated by EEG is epilepsy. The so-called epilepsy refers to patients with paroxysmal limb convulsions or abnormal consciousness behavior due to abnormal discharge of the cerebral cortex. Plays a pivotal role in the treatm...
