Abstract

The invention relates to the technical field of medical instruments, in particular to a thrombectomy balloon dilatation catheter. The thrombectomy balloon dilatation catheter comprises a balloon body,a plurality of thrombus scraping claws and an inner tube, a guide tip is connected to the front end of the balloon body, and an outer tube is connected to the rear end of the balloon body; the plurality of thrombus scraping claws are evenly distributed on the outer surface of the balloon body, the plurality of thrombus scraping claws are obliquely arranged towards the rear end of the balloon body, and a drug storage groove is formed in the side, facing the rear end of the balloon body, of each thrombus scraping claw; and the outer diameter of the inner tube is smaller than the inner diameterof the outer tube, and the outer tube and the balloon body are arranged outside the inner tube in a sleeving mode. Before the balloon body enters a human body, thrombolytic drugs are embedded in the drug storage grooves of the multiple thrombus scraping claws, and compared with drugs coated on barbs, the drug storage grooves of the thrombus scraping claws are used for carrying the drugs to enter the human body, so that the thrombolytic drug amount carried by the balloon body is greatly increased, the dissolving capacity of the drugs to thrombus with a high calcification degree is enhanced, andthe ability of the balloon body to remove thrombus with long forming time can be improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a catheter for embolectomy balloon dilation. Background technique [0002] The balloon catheter greatly simplifies the operation difficulty of surgical thrombectomy using vascular stents. The balloon adopts a double-layer structure, with barbs in the shape of blades on the outer layer, and drugs are coated on the surface of the barbs. When the balloon stent enters When the position is specified, inflate the inner layer of the balloon, stretch the balloon stent, and then open the barbs set on the outer surface, and penetrate into the inner layer of the blood vessel. By repeatedly pulling the balloon catheter, the thrombus in the blood vessel is removed. As much as possible, use the elbow catheter to absorb the thrombus. In the process of repeated pulling, the dropped thrombus will escape in both directions, causing the thrombus to fall into the blood, and the dropped thro...
