Abstract

The invention relates to the technical field of medical instruments, and discloses an electrode structure and a balloon. The electrode structure comprises a tube body, an inner electrode and an outer electrode, a tube body cavity is formed in the tube body, and a discharge channel which extends in the axis direction of the tube body and is communicated with the peripheral wall of the tube body is formed in the tube body; the inner electrode is arranged in the discharge channel; the outer electrodes are arranged on the outer peripheral walls of the two sides of the discharge channel, and the inner electrodes and the outer electrodes are conducted in a closed loop; the inner electrode, the outer electrode and the tube body are integrally formed. When the inner electrode and the outer electrode are conducted, breakdown can be carried out at the discharge channel, and then shock waves are generated and used for a focus part needing to be treated; the inner electrode, the outer electrode and the tube body are integrally formed, so that the bonding procedure in the prior art is reduced, machining is more convenient, meanwhile, the connection firmness of the inner electrode and the outer electrode is guaranteed, and then the stability of generated shock waves is guaranteed.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an electrode structure and a balloon. Background technique [0002] Cardiovascular disease has always been one of the leading causes of death in the world. Among them, atherosclerosis is a cardiovascular disease that narrows and hardens the arteries caused by plaque buildup. These plaques impede the normal flow of blood, reducing the supply of oxygen and nutrients to heart tissue. The composition of plaque usually includes fibrous tissue, fat, and calcium. Angioplasty balloons are one of the essential devices used to dilate lesions (such as calcified lesions) and restore normal blood flow in arteries. However, for calcified lesions, the internal pressure of the balloon usually needs to be very high. Gradually dilating, the pressure inside the balloon ruptures the calcified lesion, which at the same time may cause damage to the blood vessel. At present, the SHOCKWAVE M...
