Self-adaptive flexible electrode balloon device

The invention provides a self-adaptive flexible electrode balloon device. The self-adaptive flexible electrode balloon device comprises a balloon, an inner tube extending along the axis of the balloon; the electrode group is arranged on the outer wall of the inner tube in a sleeving manner and is positioned in the balloon; the electrode group comprises a first electrode and a second electrode, the first electrode and the second electrode are arranged along the axis of the inner tube, at least one end part of the first electrode is provided with the second electrode at an interval, and a discharge point position is formed between the oppositely arranged surfaces of the first electrode and the second electrode; the axial size of the first electrode is larger than that of the second electrode, and the first electrode can adapt to the bending form of the blood vessel to be bent so as to extend along the inner wall of the blood vessel. The first electrode comprises a metal tube body, at least one thread-shaped gap
