Embodiment Construction

[0024] In order to further understand the features, technical means, and specific goals and functions of the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0025] see figure 1 , the thrombus suction catheter of the present invention includes a suction tube 100 and a cannula 200. The outer surface of the suction tube 100 and the inner and outer surfaces of the cannula 200 are provided with a lubricating coating, which reduces friction and makes the movement between the components easier. Smooth, thus making it easier for the suction catheter to reach the target lesion.

[0026] see figure 1 and figure 2 , the suction tube 100 includes a tube base 11 , and the tube base 11 is connected to the catheter 12 . The tube seat 11 is used to connect the suction device and perform negative pressure suction on the thrombus. The suction device consists of a negative pressure bott...

Abstract

The invention discloses a thrombus aspiration catheter. The catheter comprises an aspiration tube, wherein the aspiration tube comprises a tube socket which is connected with a catheter; a bushing is movably sleeved on the outer wall of the aspiration tube, and comprises a Y-shaped connector, a dual-lumen catheter and a balloon; the Y-shaped connector is connected with the dual-lumen catheter, and the balloon is arranged on the outer wall of the distal end of the dual-lumen catheter; an interference metal wire can be inserted into the aspiration tube; and the distal end of the interference metal wire can extend outside the distal end of the aspiration tube. The bushing is movably arranged outside the aspiration tube, and the balloon is not limited when the aspiration tube moves, so that the thrombus aspiration catheter can quickly eliminate thrombi dispersed in a wide area of a blood vessel, and treats embolism of coronary peripheral microvessels; and when large or high-viscosity thrombus is encountered, the thrombus can be scattered by utilizing the interference metal wire and aspired, so that the thrombus aspiration catheter can treat the thrombus which is difficult to aspire.

Description

technical field [0001] The present invention relates to a medical instrument, in particular to a thrombus suction catheter for suctioning and removing waste in human blood vessels and a method of using the same. Background technique [0002] It is known that a suction catheter is used to suck the thrombus generated in the coronary artery of the heart, which can directly suck the thrombus growing in the coronary artery, preventing the thrombus from blocking the blood flow, causing acute myocardial infarction and reducing the function of the heart. The above-mentioned thrombus suction therapy is a treatment method in which a tube called a thrombus suction catheter is inserted from the leg or arm to reach the lesion in the coronary artery, and the thrombus itself is suctioned and removed. Compared with drug thrombolysis and coronary angioplasty, thrombus aspiration therapy can remove the thrombus itself that causes blood vessel narrowing or blockage, so it can avoid coronary oc...
