Abstract

The invention relates to an electrode device for generating seismic waves and a usage method. The electrode device is used for a cardiovascular stenosis lesion recanalization system. The electrode device comprises an electrode pair, a connecting wire and a catheter, the electrode device is arranged on the catheter, the arrangement mode of the electrode pair is coaxial radial arrangement, and the electrode pair comprises an electrode tip and a wire; the device can be matched with a balloon catheter to control a generator of a recanalization system to apply vibration waves to vibrate and expand a narrow blood vessel attached to the periphery of a balloon to a certain recanalization rate, the action direction and effect after the vibration waves are generated are controlled, the purpose of keeping the blood vessel normal for a long time is achieved, and finally cardiovascular stenosis is treated. The device is simple in structure, low in cost and easy to store.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to an electrode device for generating shock waves and a using method. Background technique [0002] Vascular stenosis refers to human arteriovenous vessels, such as coronary arteries, peripheral vessels, and intracranial vessels. Due to abnormal lipid metabolism, lipids in the blood are deposited on the smooth intima of blood vessels, and gradually accumulate into atherosclerotic lipids. Plaque-like plaques, as time goes by, these plaques increase or even calcify, causing narrowing of the blood vessel lumen, blocking blood flow, leading to ischemia of downstream blood vessels and the body, and corresponding clinical manifestations. If the stenosis occurs in the coronary artery, it will cause palpitations, chest pain, dyspnea, and angina pectoris. In severe cases, it will lead to myocardial insufficiency or myocardial necrosis; if it occurs in the periphery, it ...
