Aorta intracavity infusion tube

Abstract

The invention relates to an aorta intracavity infusion tube. The aorta intracavity infusion tube comprises an infusion tube body, a pressurizing part and a suction tube, wherein the pressurizing part is sleeved out of the infusion tube body; and the suction tube and the infusion tube body are arranged in parallel. The invention provides the aorta intracavity infusion tube without requirement of profound hypothermia and capable of reducing influence of the temperature-reducing temperature-recovering process on functions of important organs of the whole body.

Description

technical field [0001] The invention belongs to medical equipment, and relates to a perfusion tube, in particular to an aortic cavity perfusion tube. Background technique [0002] For most patients with aortic dissection and large vessel aneurysm involving the aortic arch, stent placement in the descending aorta (modified "elephant trunk operation") is required during the operation, and the whole body temperature needs to be lowered to 18-24 Celsius, and then in the case of selective low-flow brain perfusion, the descending aorta internal circulation is stopped, that is, the distal descending aorta is perfused with organs, including the spinal cord, liver, kidney, digestive tract, etc. There is no blood perfusion, and the descending aorta will be stented After direct vision implantation and anastomosis of the proximal end of the stent with the artificial vessel at the end of the ascending aorta, the blood perfusion in the descending aorta is restored. The time of circulatory...

Problems solved by technology

[0002] For most patients with aortic dissection and large vessel aneurysm involving the aortic arch, stent placement in the descending aorta (modified "elephant trunk operation") is required during the operation, and the whole body temperature needs to be lowered to 18-24 Celsius, and then in the case of selective low-flow brain perfusion, the descending aorta internal circulation is stopped, that is, the distal descending aorta is perfused with organs, including the spinal cord, liver, kidney, digestive tract, etc. There is no blood perfusion, and the descending aorta will be stented After direct vision implantation and anastomosis of the proximal end of the stent with the artificial vessel at the end of the ascending aorta, the blood perfusion in the descending aorta is restored. The time of circulatory arrest at the distal end of the descending aorta is generally within 60 minutes. The process of cooling and rewarming may easily cause ischemia of remote organs and cause corresponding complications, including acute liver and kidney insufficiency, gastrointestinal dysfunction, and spinal cord ischemia causing neurological symptoms. In severe cases, paraplegia, severe Liver and kidney failure, leading to poor postoperative recovery, serious complications, or death in patients

At present, there are no relevant reports on medical devices or measures for solving the above technical problems at home and abroad
