Embodiment 1

[0025] See figure 1 , a four-branch artificial blood vessel for perfusion of aortic arch replacement, comprising a main artificial blood vessel 1, an artificial blood vessel of a branch of the brachiocephalic artery 2, a common secondary branch artificial blood vessel of the left common carotid artery and the left subclavian artery 3, a left common carotid artery The artificial blood vessel 4 of the third-order branch of the artery, the artificial blood vessel 5 of the third-order branch of the left subclavian artery, and the artificial blood vessel 6 of the arterial perfusion branch. One end of the main body artificial blood vessel 1 is in communication with the artificial blood vessel 2 which is a branch of the brachiocephalic artery. There are also two notches on the side wall of the main artificial blood vessel 1 , and the two notches are respectively located on opposite side walls of the main artificial blood vessel 1 . One of the gaps is connected to one end of the comm...

Embodiment 2

[0028] See Figure 4 , different from Example 1, the four-branch artificial blood vessel in Example 2 does not include the common secondary branch artificial blood vessel of the left common carotid artery and the left subclavian artery, that is, the four-branch artificial blood vessel in this embodiment includes the main body artificial blood vessel Blood vessel 1, brachiocephalic artery branch artificial blood vessel 2, left common carotid artery secondary artificial blood vessel 3, left subclavian artery secondary artificial blood vessel 4, and arterial perfusion branch artificial blood vessel 5. In this embodiment, the secondary artificial blood vessel 3 of the left common carotid artery and the secondary artificial blood vessel 4 of the left subclavian artery are directly connected to the artificial blood vessel 1 of the main body, and both are located on the same side of the artificial blood vessel 1 of the main body. The blood vessel 5 is also directly connected to the m...

Abstract

The invention provides a four-branch artificial blood vessel for arcus aortae portion replacement perfusion. The artificial blood vessel comprises a body artificial blood vessel for introducing blood for perfusion and a brachiocephalic artery branch artificial blood vessel, a left common carotid artery branch artificial blood vessel and a left subclavian artery branch artificial blood vessel which are communicated with the body artificial blood vessel. An arterial perfusion branch artificial blood vessel communicated with extracorporeal circulation is further arranged on the body artificial blood vessel. Perfusion can be performed on the bilateral whole brain and the whole body during operation, the brain perfusion during operation during profound hypothermia circulation arrest is ensured to the maximum extent, postoperative neurological complications can be reduced, the operation technique can be simplified, and the operation time is shortened, so that the purposes of improving the operation success rate and reducing related operation complications are achieved.

Description

technical field [0001] The invention relates to the technical field of medical devices, and more specifically, to a four-branch artificial blood vessel for perfusion of aortic arch replacement. Background technique [0002] When aortic surgery involves aortic arch replacement surgery, a long process of deep hypothermic circulatory arrest is required. During this process, the temperature of the human body drops to 18-25°C. At this time, most of the brain undergoes unilateral cerebral perfusion, and the rest of the organs are closed. An ischemic state in which blood perfusion is stopped. There is a possibility of hypoperfusion of the brain during this operation, which will lead to a series of postoperative neurological complications such as coma and delirium. Currently, most cerebral perfusions are performed unilaterally through cannulation of the axillary artery. Cannulation of the axillary artery itself increases operative time and may lead to related complications such as...
