Catheter for myocardial protection liquid perfusion through percutaneous intervention

Abstract

The invention discloses a catheter for myocardial protection liquid perfusion through percutaneous intervention, and belongs to medical instruments. A fifth channel hole is positioned between a firstballoon and a first channel, so that the blood in the left ventricle can be led out of the body and enter an extracorporeal circulation machine so as to play a role in reducing the pressure of the left ventricle. After percutaneous interventional placement, the catheter can be used for perfusing myocardial protection liquid to stop the heart, to deflate the heart and ascending aorta, and to avoidadhesion with the back of the sternum; and when the sternum is split longitudinally, the tearing of the heart and ascending aorta is avoided. The catheter is used for is preventing the heart and the ascending aorta from being damaged when the sternum is longitudinally split, and when the heart and the aorta are adhered to the anterior mediastinum, or the enlarged heart and the ascending aorta aretightly attached to the sternum.

Description

technical field [0001] The invention belongs to medical equipment, and relates to a catheter for infusing percutaneous myocardial protection solution. Background technique [0002] When performing surgery on the heart, it is necessary to perfuse the heart with myocardial protective fluid to keep the heart in a static state of electrical and mechanical activity (that is, the heart stops beating), so as to ensure safe and efficient operation while protecting the heart; clinically, it is often encountered that the sternum is opened again For re-heart surgery, after the first heart surgery, there will be adhesions between the outer surface of the heart or the ascending aorta and the sternum. The risk of aortic tear, causing the blood in the heart and ascending aorta to rush out, causing serious surgical accidents; when encountering a significantly enlarged heart or a significantly dilated ascending aorta, the heart or ascending aorta will cling to the sternum Posteriorly, a lon...

[0002] When performing surgery on the heart, it is necessary to perfuse the heart with myocardial protective fluid to keep the heart in a static state of electrical and mechanical activity (that is, the heart stops beating), so as to ensure safe and efficient operation while protecting the heart; clinically, it is often encountered that the sternum is opened again For re-heart surgery, after the first heart surgery, there will be adhesions between the outer surface of the heart or the ascending aorta and the sternum. The risk of aortic tear, causing the blood in the heart and ascending aorta to rush out, causing serious surgical accidents; when encountering a significantly enlarged heart or a significantly dilated ascending aorta, the heart or ascending aorta will cling to the sternum Posteriorly, a longitudinal sternal split is performed at this time, with the same risk of tearing the heart or ascending aorta
