Abstract

The invention discloses a novel thrombus aspiration composite balloon system. The system comprises a guide tube and an aspiration tube, wherein the guide tube is sleeved with the aspiration tube, the guide tube comprises a thrombus intercepting structure used for blocking a distal blood vessel, and the thrombus intercepting structure is located at the distal end of the guide tube; and the aspiration tube comprises a blood vessel opening structure and a negative pressure suction structure, the blood vessel opening structure is arranged at the distal end of the aspiration tube, and the negative pressure suction structure is arranged at the proximal end of the aspiration tube. The thrombus intercepting structure can intercept thrombus softened and floating by negative pressure, and thrombus embolism caused by the fact that the thrombus flows along with blood is prevented.

Description

Technical field

[0001] The present invention belongs to the technical field of medical devices, and is specifically related to a new thrombus suction composite balloon system. Background technique

[0002] Those is mainly divided into two kinds, one is to draw blood in the use of catheters, and the catheter is reached inside the thrombus, and the thrombosis is relatively inexpensive. The prices are relatively inexpensive, the suction effect is mainly according to the catheter The diameter is determined that if the catheter is relatively thick, the suction effect is better. The other is mechanical suction, there is a dedicated hydrocarrier, and is also entered into the thrombus through the blood vessel, and the drug is injected into the thrombolytic drug in the thrombus, and the drug will be dissolved for a while, and then the machine will be opened. Soft thrombus that has been dissolved is suck in vitro.

[0003] Mechanical thrombosis suction is considered to be a new type, safe,...
