Description

Technical Field

[0001] This utility model relates to a processing positioning device, and in particular to a balloon occlusion perfusion tube for the descending aorta, belonging to the technical field of positioning devices. Background Technology

[0002] In cardiac and major vascular surgery, when repairing diseased vessels in the aorta or carotid artery, it is necessary to expand, replace, and isolate the damaged vessel area. During isolation, aortic perfusion must simultaneously ensure normal blood perfusion to the brain and body. Currently, when replacing lesions, it is not possible to simultaneously perfuse the aortic arch branch area and the upper body. Only lower body circulatory arrest and selective cerebral perfusion methods can be used. However, this method carries the risk of damage to the nervous system and spinal cord. To avoid damage to the nervous system and spinal cord, deep hypothermia and a strict reduction in surgical time are required. Therefore, a balloon occlusion perfusion cannula for the descending aorta of the aortic arch is proposed. Utility Model Content

[0003] In view of this, the present invention provides an aortic arch descending aorta balloon occlusion perfusion catheter to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

[0004] The technical solution of this utility model is as follows: an aortic arch descending aorta balloon occlusion perfusion tube, comprising an aortic occlusion balloon, an aortic balloon catheter, an aortic arch branch occlusion balloon, an aortic arch branch balloon catheter, an aortic inner Luer connector, an aortic arch inner Luer connector, a connecting seat, a connecting sleeve, and a tee (with a tee connector);

[0005] One end of the aortic balloon catheter is connected to one side of the fixed connecting tube seat, one end of the connecting sleeve is fixedly connected to the other side of the connecting tube seat, the other end of the connecting sleeve is installed at one end of the three-way valve, the other end of the aortic balloon catheter is equipped with an aortic occlusion balloon, and one end of the aortic arch branch balloon catheter is fixedly connected to one side of the connecting tube seat.

[0006] More preferably, the lateral wall of the aortic balloon catheter is fitted with an aortic internal Luer connector, and the lateral wall of the aortic arch branch balloon catheter is fitted with an aortic arch internal Luer connector.

[0007] More preferably, both the aortic balloon catheter and the aortic arch branch balloon catheter are double-lumen catheters, wherein the side lumen is connected to the interior of the occlusion balloon.

[0008] A further preferred option is a blood supply system connected to a three-way valve.

[0009] In a further preferred embodiment, both the aortic balloon catheter and the aortic arch branch balloon catheter are connected to the connecting port to provide blood perfusion.

[0010] A further preferred embodiment involves using an injection device connected to the aortic inner Luer connector to infuse fluid into the aortic occlusion balloon, filling the aortic occlusion balloon with solution, and using an injection device connected to the aortic arch inner Luer connector to infuse saline into the aortic arch branch occlusion balloon, filling the aortic arch branch occlusion balloon with solution.

[0011] The present invention has the following advantages due to the adoption of the above technical solution:

[0012] The aortic arch and descending aorta balloon occlusion perfusion catheter described in this invention is reasonably designed, practical, and easy to use. It enables simultaneous vascular occlusion and blood perfusion of the aortic arch and descending aorta using this catheter, avoiding the risks of nervous system and spinal cord damage caused by deep hypothermic circulatory arrest, and effectively reducing patient medical costs and minimizing harm to the body during surgery.
