Abstract

The invention provides an implanted electrode and an implanted electrical stimulation system. The implanted electrode comprises a base body and electrode stimulation pieces, wherein the base body is tubular or columnar, at least two mounting grooves are formed in the same axial position of the base body in the circumferential direction of the base body, and guide grooves are formed in the positions, at the two axial ends of the mounting grooves, of the inner wall of the base body; the at least two electrode stimulation pieces are respectively and correspondingly arranged in the mounting grooves; each electrode stimulation piece comprises an electrode plate and an anchor structure connected with the corresponding electrode plate; and each electrode plate is located in the corresponding mounting groove, the outer surface of each electrode plate is exposed outside the base body, and at least part of the anchor structures is located in the guide groove and cooperates with the guide grooves, so that the center line of the outer surface of each electrode plate is parallel to the axis of the base body. According to the configuration, the implanted electrode realizes initial positioning before the electrode plates and the base body are fixed through cooperation of the anchor structures and the guide grooves, so that the central lines of the outer surfaces of the electrode plates are parallel to the axis of the base body, orientation and positioning during processing are facilitated, and the situation that the yield is influenced due to rotation dislocation of the electrode plates in the subsequent fixing and processing process is avoided.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an implanted electrode and an implanted electrical stimulation system. Background technique [0002] Implantable active medical devices are now widely used in the treatment of various diseases, especially in the treatment of physical and psychological diseases. Compared with many traditional treatment methods, this treatment method has better and direct curative effects. One of the implantable active medical devices is a nerve electrical stimulator, which transmits pulse signals to nerve tissue through implanted electrodes to improve the normal skills of the human body, such as: implanted deep brain stimulation electrodes (Deep Brain Stimulation, DBS) can effectively improve limb control and coordination in patients with Parkinson's Disease (PD). [0003] Parkinson's disease is a common neurodegenerative disease, and drug therapy is the main treatment in its early and mi...
