Instrument for arterial occlusion lesion treating and application thereof

Abstract

The invention discloses an instrument for arterial occlusion lesion treating and the application thereof. The instrument comprises a vascular ultrasound catheter, a treating micro catheter and a treating guiding line. The vascular ultrasound catheter and the treating micro catheter are integrally connected in parallel. One part of the treating guiding line is placed in the treating micro catheter, and the other part of the treating guiding line penetrates out of the treating micro catheter from a side wall outlet. According to the instrument, the vascular ultrasound catheter and the treating micro catheter are integrally connected in parallel, a double-cavity micro catheter is used for adjusting the treating guiding line to enter a vessel true lumen, thrombus is sucked out through the treating guiding line, and post-operation hidden danger is removed through one-time curing. The problem that in an intervention recanalization treating operation of blocking of coronary arteries, peripheral arteries and other organ pipelines, a treating guiding line cannot enter a true lumen easily is solved.

Description

technical field [0001] The present invention relates to the technical field of arterial occlusion treatment devices. Background technique [0002] Coronary heart disease is the first killer of human health, and chronic total occlusion of coronary artery (CTO) is the most serious type. Coronary chronic total occlusion (CTO) lesions were defined as 3 months of disease course, partial lumen occlusion and complete disappearance of forward blood flow on coronary angiography, distal blood flow myocardial infarction thrombolysis test (thrombolysis in myocardial infarction) Infarction, TIMI) grade 0; or only a little anterior blood flow through, but no distal vascular filling (TIMI flow grade 1), the latter is also called "functional" CTO. CTO lesions account for about 12%-20% of all patients undergoing percutaneous coronary intervention (PCI) in clinical practice. Interventional treatment of CTO lesions is the most technically difficult and has a low success rate. The significanc...

Problems solved by technology

[0008] The technical problem to be solved by the present invention is to provide a device for treating arterial occlusive lesions. The vascular ultrasound catheter and the treatment microcatheter are connected in parallel, and the double-lumen microcatheter is used to adjust the treatment guide wire to enter the true lumen of the blood vessel, and the treatment guide wire sucks out the thrombus. , one-time cure, eliminating postoperative hidden dangers; the invention solves the problem that the guide wire is not easy to enter the true lumen in the interventional recanalization treatment of coronary artery, peripheral artery and other organ duct occlusion
