Abstract

The invention provides an intracranial electrode plate. The intracranial electrode plate comprises a flexible substrate, electrode contacts, electrode pins, leads, bunching pipes and lead connectors, wherein the electrode contacts are arranged on the surface of one side of the flexible substrate; each electrode contact is provided with an electrode pin; the electrode pins are located in the flexible substrate; different electrode pins are connected with one end of different leads in the flexible substrate; an insulating film is arranged on the outer surface of each lead; one end of the bunching pipe is connected with one side of the flexible substrate; the other end of the bunching pipe is sleeved with a plurality of lead connectors; and the other ends of the different leads are connected with the different lead connectors on the bunching pipes. According to the electrode plate provided in the scheme, the flexible substrate material is adopted to relieve extrusion of the electrode plate to cortex, the electrode contacts are fixed in the mode that the electrode contacts are fixed through the electrode pins, the electrode contacts can be fixed, and therefore the time for collecting electroencephalogram signals is prolonged to a certain degree, and the detection precision and resolution are improved.

Description

technical field [0001] The invention relates to the technical field of brain neural engineering, in particular to an intracranial electrode sheet. Background technique [0002] The brain controls human activities by sending out normal EEG signals. EEG signals contain a wealth of brain activity information. Detection of EEG signals is an important means for brain research, physiological research, and clinical diagnosis of brain diseases. [0003] There are currently many methods for collecting specific EEG signals. One method is the collection of scalp EEG (Electroencephalogram, electroencephalogram), which is the most commonly used and most economical non-invasive EEG detection method. Another method is the intracranial electrode (Intracranial EEG, iEEG) detection method. Specifically, this method requires the patient to perform an invasive assessment before surgery, and then the surgeon will open the cranium, and through the skull drilling or stereotaxic instrument, the Th...
