Description

Technical Field

[0001] The present invention relates to the technical field of thrombus removal, in particular to a novel thrombus removal device. Background Art

[0002] Thrombus is a small piece of blood formed on the surface of the peeling or repaired part of the inner surface of the cardiovascular system. Thrombosis is a multi-factor change process caused by the interaction and mutual influence of a group of genetic and environmental factors. Thrombus has different degrees of adverse effects on the body, such as blocking blood vessels, causing embolism, causing valve deformation and extensive bleeding, etc. Common acute myocardial infarction, cerebral artery thrombosis, cerebral embolism, etc. are all adverse. Timely treatment of thrombosis is required. Thrombosis treatment mainly dissolves and removes thrombus and restores vascular function, including drug and surgical treatment;

[0003] A thrombus removal device is a device used to remove a thrombus. It usually uses a thrombus aspiration catheter to enter the opening of the blood vessel from the femoral artery or the radial artery, and then a special thrombus removal device is inserted from the end of the catheter into the proximal and distal ends of the thrombus in sequence until the thrombus is completely removed. However, when the thrombus is extracted for treatment, the direction and position of the catheter cannot be controlled during the process of sending the catheter downward to remove the thrombus. Sometimes the balloon cannot accurately enter the embolic blood vessel, resulting in residual thrombus, which in turn causes the blood to re-aggregate into formed elements to form an embolus, causing the patient's condition to relapse. For this reason, we propose a new thrombus removal device. Summary of the invention
