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-pressure shock wave generating system for cardiovascular stenosis lesions. Background technique [0002] Vascular stenosis refers to the arterial and venous blood vessels of the human body, including coronary, peripheral, intracranial and other blood vessels. Due to abnormal lipid metabolism, the lipids in the blood are deposited on the originally smooth vascular intima, and gradually accumulate into atheromatous lipids. Plaque-like plaques. Over time, these plaques increase and even calcify, causing stenosis in the vascular lumen, blocking blood flow, and causing ischemia in downstream blood vessels and bodies, resulting in corresponding clinical manifestations. If the stenosis occurs in the coronary artery, it will cause palpitations, chest pain, dyspnea, and angina pectoris, and in severe cases, it will lead to myocardial insufficiency or myocardia...
