Electrode assembly, electrode implantation positioning system, and electrode implantation positioning method

Abstract

The present invention belongs to the field of electrical stimulation technology, and discloses an electrode assembly, an electrode implantation positioning system, and an electrode implantation positioning method. The electrode assembly includes an electrode body, and the electrode body includes an implantation end and a connection end. The connection end is used to connect a pulse generator, and the implantation end is provided with at least one electrode sheet for implantation into a target point of a patient's brain, and a magnet is provided inside the implantation end; the electrode implantation positioning system includes the above electrode assembly, multiple groups of magnetic detection components, and a processor, and the multiple groups of magnetic detection components constitute a magnetic field coordinate system, and each group of magnetic detection components is used to detect the magnetic field strength of the magnet in the magnetic field coordinate system; the processor is used to determine the spatial position of the implantation end of the electrode body according to the detection results of the multiple groups of magnetic detection components. Through the present invention, the advancement position and process of the electrode body can be monitored in real time, blindness in the implantation process can be avoided, and the controllability of the electrode body implantation can be improved.
