Abstract

The invention relates to a vascular recanalization system and method for vascular stenosis lesion. The vascular recanalization system comprises an energy generating device, an operating handle and balloons, the energy generating device is connected with the operating handle, the operating handle is connected with a catheter, the other end of the catheter is connected with the balloons, the balloons comprise the inner balloon and the outer balloon, the inner balloon is connected with the catheter, and the outer balloon is connected with the catheter. A catheter wire is arranged in the inner balloon, and an electrode device and a marking ring are arranged on the catheter wire. The device can reach a target narrow position through the guide wire in a conventional interventional operation mode, and pressure in the balloon is controlled through the conductive fluid medium, the energy generating device and the electrode device, so that blood vessels are expanded, and target recanalization is achieved; specific anti-regeneration medicine can be injected to a lesion position through the medicine injection cavity and directly acts on the vascular stenosis position, the medicine loss amount is small, the purpose of keeping blood vessels unobstructed for a long time is achieved, the purpose of treating vascular stenosis is finally achieved, and damage to a human body is small.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to a blood vessel recanalization system and method for vascular 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 periphery,...
