Branch type sawtooth-shaped thrombus breaking balloon catheter

Abstract

The invention discloses a branch type sawtooth-shaped thrombus breaking balloon catheter. The balloon catheter comprises a catheter cavity connector and a balloon cavity connector, the upper right side of the catheter cavity connector is connected with the balloon cavity connector, the right end of the catheter cavity connector is mutually connected with the left end of a balloon tube, a guide tube is arranged in an inner cavity of the balloon tube, the upper portion of the right end of the balloon tube is mutually connected with a small balloon, the guide tube and the balloon tube form a double-cavity catheter, the outer diameter of the double-cavity catheter is 1.91 mm, the space and the function of the double-cavity catheter are mutually independent, the lower portion of the right end of the balloon tube is mutually connected with a large balloon, a near-end marking point is arranged at the middle end of the guide tube, and a far-end marking point is arranged at the right end of the guide tube. The branch type sawtooth-shaped thrombus breaking balloon catheter can be operated in the two directions perpendicular to each other to cut and break thrombus, the dosage of thrombolysis medicine is reduced, and meanwhile the thrombolysis effect can be improved; and in addition, the risk of pulmonary embolism caused by thrombosis can further be reduced.

Description

Technical field[0001]The present invention relates to the field of medical devices, and in particular, a scaled serrated crushed ball capsule catheter.Background technique[0002]Venous ThromboemBolism (VTE) includes deep venous thrombosis, DVT and pulmonary thromboembolism, PTE, which is the same illness in different pathogenesis and different tissue organs. Deep venous thrombosis in lower limbs refers to a clinical syndrome of a peri-vein system due to a variety of reasons, forming a thrombosis, causing clinical syndrome of corresponding angiogenesis. At present, it is considered that venous blood flow lags, vein wall damage, and blood high-rise state are three major causes of deep venous thrombosis. When the venous thrombosis of the lower extremity, the plug can enter the pulmonary artery in the blood flow, which can cause fatal pulmonary artery embolism, seriously endangering the lives of patients. In the United States, the VTE incidence is about 1.17 / 1000 people. The annual VTE...

Problems solved by technology

Drug-mechanical combined thrombectomy uses the principle of negative pressure suction to pulverize the thrombus and suck it out of the body, and at the same time, combined with local thrombolytic drug injection perfusion, it can accelerate thrombus dissolution and reduce the dosage of thrombolytic drugs; It is difficult for most patients to pay high surgical fees, which limits its further use
