Abstract

The invention relates to the technical field of medical devices, in particular to a rapid exchange double-lumen micro catheter for reverse thrombolysis and a use method thereof. The rapid exchange double-lumen micro catheter comprises a drug injection lumen and a guide wire fixing lumen, wherein the guide wire fixing lumen is formed in the side wall of the drug injection lumen, the extension direction of the guide wire fixing lumen is the same as that of the drug injection lumen, and the guide wire fixing lumen is arranged on a guide wire in a sleeving way; one end of the drug injection lumen is communicated with an external syringe, and a drug outlet is formed in the other end of the drug injection lumen. According to the rapid exchange double-lumen micro catheter for reverse thrombolysis provided by the invention, as the guide wire fixing lumen is arranged on the guide wire in a sliding way, in the process of the reverse thrombolysis, the thrombolysis and operation processes can be completed only through enabling the guide wire to enter a primary culprit blood vessel, so that the situation that the guide wire repeatedly goes in and out of a lesion blood vessel is avoided, the coming-out of the guide wire from a coronary artery is also avoided, the steps of operation are effectively simplified, and the risk of complications is reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a rapid-exchange double-lumen microcatheter for reverse thrombolysis and its application method. Background technique [0002] Emergency PCI refers to the coronary artery revascularization performed within 12 hours after the patient has acute myocardial infarction. The patient first undergoes coronary angiography in the cardiac catheterization laboratory to find out the coronary "culprit" blood vessel and its lesion site. Percutaneous transluminal coronary angioplasty and implantation of stents at the lesion site can recanalize the occluded blood vessels, and early reperfusion and functional recovery of the infarction-related myocardium. It can be said that emergency PCI has built a green channel in the shortest time to save the dying life of acute myocardial infarction, and improves the success rate of rescue of critically ill patients. [0003] Acute myocardial infarct...
