Catheter used for removing thrombus

Abstract

The invention provides a catheter used for removing a thrombus. The catheter comprises a catheter body and a Luer taper, wherein the catheter body comprises a hollow central tube and a hollow outer tube, one end of the central tube penetrates through the outer tube to be connected with a central tube control handle, the other end of the central tube is connected with a tip end, and one end of theouter tube is connected with an outer tube handle; the tip end is internally provided with a guide wire cavity, and the guide wire cavity penetrates through the tip end and is communicated with the central tube; the central tube is internally provided with a guide wire; the contact connector of the outer tube and the tail end of a Luer taper handle is a standard Luer contact connector, and the central tube control handle dock with the outer tube handle through the Luer taper at the front end, so that the position of the central tube in vivo can be controlled; the end, close to the tip end, ofthe central tube is provided with a developing mark. The catheter used for removing the thrombus has the advantages that the catheter is safe and effective, the structure is simple, the operation is convenient; the catheter can quickly, effectively and thoroughly remove the thrombus of a diseased region in short time, so that a blocked coronary vessel of a patient thoroughly recover the blood supply function.

Description

Technical field [0001] The invention relates to the technical field of medical machinery, in particular to a catheter used for removing thrombus. Background technique [0002] Thrombus aspiration catheter and thrombectomy related technologies are a physical treatment method that has emerged in recent years. It can quickly and effectively remove the thrombus in the infarcted coronary artery, improve the blood flow in the distal coronary artery, and restore the reperfusion of myocardial cells, which is fast and effective. It can restore blood flow in blood vessels related to infarction and rescue ischemic necrosis of myocardium, restore cardiac function, and reduce the occurrence of adverse cardiac events. It has a good short-term and long-term effect on the treatment of patients with acute myocardial infarction. Moreover, clinical applications show that the use of thrombus After the suction catheter is aspirated, the stent can be directly implanted without balloon pre-dilation in ...

AI Technical Summary

Problems solved by technology

[0008] The technical problem to be solved by the present invention is that the thrombus suction catheter cannot completely remove the thrombus, and the anti-twisting ability and support ability are not strong enough. In order to solve the above problems, the present invention provides a catheter for removing thrombus
