Title:
IMPLANTED ELECTRODE AND IMPLANTED ELECTRICAL STIMULATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/077829
Kind Code:
A1
Abstract:
The present invention provides an implanted electrode and an implanted electrical stimulation system. The implanted electrode comprises: a base body, the base body being tubular or columnar, at least two mounting grooves being formed at the same axial position of the base body in the circumferential direction of the base body, and guide grooves being formed on the inner wall of the base body at both axial ends of each mounting groove, and an electrode stimulation member provided in each mounting groove; the electrode stimulation member comprises an electrode sheet and an anchor structure connected to the electrode sheet; the electrode sheet is located in the mounting groove; the outer surface of the electrode sheet is exposed outside the base body, and at least part of the anchor structure is located in the guide groove and matches the guide groove, such that the outer surface of the electrode sheet is parallel to the axis of the base body. According to the configuration, the implanted electrode implements, by means of the matching of the anchor structure and the guide groove, initial positioning before the electrode sheet and the base body are fixed, so as to ensure that the central line of the outer surface of the electrode sheet is parallel to the axis of the base body, facilitating orientation and positioning during processing, and avoiding the situation that the yield is influenced due to rotation dislocation of the electrode sheet in the subsequent fixing and processing process.
