Electrode lead and method of identifying electrode pad orientation

Abstract

The application relates to the technical field of medical products, and discloses an electrode lead wire and a method for identifying the direction of an electrode sheet. The electrode lead wire comprises a stimulation end, a connecting end and an intermediate section connecting the stimulation end and the connecting end, the stimulation end is provided with at least one first-direction electrode assembly, the first-direction electrode assembly comprises first, second and third electrode sheets which are arranged in an insulating interval along a circumferential direction, and the lengths of the first electrode sheets in the axial direction of the electrode lead wire are respectively smaller than the lengths of the second and third electrode sheets. After the electrode lead wire is implanted into a human body, the angles and positions of the first, second and third electrode sheets in the first-direction electrode assembly can be obtained through a CT image, the electrode sheets working in a specific direction are facilitated to be controlled, an additional direction mark is not needed to determine the rotation direction of a contact point, the product structure is optimized, the metal consumption of the electrode lead wire is reduced, and the cost is saved.
