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 invention relates to the technical field of arterial occlusion treatment appliances. Background technique

[0002] Coronary heart disease is the first killer that endangers human health, and coronary chronic total occlusion (CTO) is the most serious type. Chronic total occlusion (CTO) of coronary arteries was defined as a disease course of 3 months, local lumen occlusion, complete disappearance of forward blood flow seen in coronary angiography, and thrombolysis in myocardial infarction (TIMI) of distal blood flow 0 or only minimal forward flow but no distal vascular filling (TIMI flow grade 1), the latter is also referred to as a "functional" CTO. CTO lesions account for about 12%-20% of all patients undergoing percutaneous coronary intervention (PCI) in clinical practice. The interventional treatment of CTO lesions is the most technically difficult and has a low success rate. The significance of successful PCI is that it can relieve the symptom...
