Description
Technical Field
The application relates to the technical field of seismic wave sacculus, in particular to a seismic wave sacculus electrode assembly.
Background
Vascular calcification is a vascular stenosis and sclerosis disease caused by the accumulation of plaque in the blood vessels of the human body, the plaque consisting of fibrous tissue, fat and calcium. The accumulated calcified plaque impedes the normal flow of blood, resulting in a lack of supply of body oxygen and nutrients. The lower limb arteriosclerosis is caused by peripheral blood vessels, the lower limb is cooled, numb and intermittent claudication are caused by light lower limb, and the lower limb artery, especially the instep artery, can be weakened or vanished due to heavy lower limb artery, and even amputation treatment is needed. Vascular calcification occurs in coronary arteries and is manifested clinically by coronary atherosclerotic heart disease, myocardial ischemia, angina pectoris, and myocardial infarction.
In recent years, for the treatment of vascular calcification lesions, a minimally invasive interventional mode is mainly adopted for treatment, and mainly comprises a high-pressure balloon, a chocolate balloon, a cutting balloon, a spinous process balloon, a nicking balloon and plaque rotary cutting/rotational grinding technology, but the devices have the limitations and high complications, can only treat shallow calcification, and cannot treat severe calcification, eccentric calcification and the like.
Based on this, a new technology has recently emerged, namely, extending extracorporeal lithotripsy to the field of vascular intervention, by inserting a catheter containing a balloon at the distal end into the vessel, the balloon expanding against the wall at the calcified lesion, at which time the electrodes inside the balloon generate, under the communication of a high-voltage generator, a electrohydraulic wave source which, when excited, releases a high-voltage shock wave, which generates a shock wave due to cavitation. The shock wave propagates through the liquid medium and impacts and fractures the calcified area in the blood vessel through the balloon wall to crush calcified substances, restore elasticity of the blood vessel, remodel the diseased blood vessel, and simultaneously avoid damage to the inner wall/intima of the blood vessel.
Current common practice for the electrode portion of a seismic balloon is to lap weld the wire to the electrode sheet from the side, and similar operations also occur with the connection of two electrode rings. In the method, the overall outer diameter of the electrode finished product attached to the inner tube is larger, the outer diameter of the folded balloon is not reduced, the cylindrical lead wire is in line contact with the arc surface, and the tensile strength is lower.
