The invention discloses an iliofemoral deep venous moniliform eccentric sacculus thrombolytic thrombolysis thrombectomy catheter and a using method of the iliofemoral deep venous thrombosis moniliform eccentric sacculus thrombolysis thrombectomy catheter. The tail end of the catheter is composed of two openings, wherein one is a sacculus catheter opening, and the other one is called a Y valve connector, is a common entrance of a guide wire for guiding and a thrombolysis catheter, and is used by being connected with a Y valve. A catheter end is a two-cavity catheter composed of two catheters in a fusing mode, wherein the two catheters are mutually independent in function, one cavity serves as a sacculus catheter passage, and the other cavity serves as a guide wire and thrombolysis catheter passage. A catheter working part is composed of moniliform eccentric sacculus and a corresponding crack thrombectomy catheter on the other side. Catheter cavities are made of a +PTEE hydrophilic coating. Each part of the sacculus and each part of thrombolysis (with the length of 10-20cm) can work respectively or simultaneously. Sacculus (with the diameter of 5-20mm) squeezes thrombectomy. Thrombectomy medicine thrombolysis can be simultaneously filled in the crack catheter on the other side. The crack catheter on the other side can rotate so as to improve thrombolysis thrombectomy effect.
