Problems solved by technology

However, the pulse parameter setting in the energy generation controller used in this invention is relatively simple, and it cannot detect and control the energy released by the pulse, and cannot realize the continuous adjustment of the pulse voltage, and releases multiple pulses independently and continuously for severe areas, with few functions. The effect of the system on lesion treatment is weakened, and the system has higher requirements on the withstand voltage of the components when realizing the pulse, and the cost is higher

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to a high-voltage shock wave generating system for cardiovascular stenosis. 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 peripher...
