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

Embodiment Construction

[0019] see figure 1 , the present invention provides an aortic perfusion tube comprising a perfusion tube body 2 , a pressurizing component sleeved outside the perfusion tube body 1 , and a suction tube 5 arranged in parallel with the perfusion tube body 1 . The pressurization part is flat and sleeved on the outside of the perfusion tube body 1. The pressurization part is designed in a flat shape, which is convenient for better attachment to the blood vessels in the stent. The patient's diseased blood vessels fit better.

[0020] The pressurization component includes a flat pressurization balloon 3 and a pressurization tube 4 connected with the pressurization balloon 3; the flat pressurization balloon 3 is sleeved on the outside of the perfusion tube body 1; the pressurization tube 4 and the The perfusion tube bodies 1 are arranged in parallel. Simultaneously, the supercharging component also includes a supercharging chamber 7 connected to the end of the supercharging pipe 4...

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...
