Abstract

The utility model discloses an implantable nerve stimulation electrode and an implantation system and a stimulation system thereof. The stimulation electrode comprises a far-end electrode, an outer sleeve and an electrode body, the electrode body is formed by spirally winding n electrode wires, and each electrode wire comprises a metal wire and an insulating layer wrapping the metal wire, so that the electrode body is of an insulating spiral structure; the outer sleeve is sleeved outside the far end of the electrode body, the near end of the electrode body is exposed, a far end port of the outer sleeve is sealed by a first sealing element, and a near end port of the outer sleeve is sealed by a second sealing element; the far-end electrodes are arranged on the outer sleeve in a sleeving mode, the number of the far-end electrodes is n, the n far-end electrodes are electrically connected with the far ends of the n electrode wires respectively, and n is a positive integer larger than or equal to 1. And the far end part of the electrode body is sleeved with the outer sleeve, so that the fatigue resistance is improved, meanwhile, the stress of the electrode body is small, the reliability is improved, and the safety is further improved. The near-end part of the electrode body is an exposed spiral electrode body, so that the wound on the human body is small, the healing is fast, and the infection risk is reduced.
