Quick connecting type four-branch artificial blood vessel for irrigation

Abstract

The invention relates to a quick connecting type four-branch artificial blood vessel for irrigation. The quick connecting type four-branch artificial blood vessel comprises a main body artificial blood vessel, a brachiocephalic artery branch artificial blood vessel, a left common carotid secondary branch artificial blood vessel and a left subclavian artery secondary branch artificial blood vessel,wherein the brachiocephalic artery branch artificial blood vessel, the left common carotid secondary branch artificial blood vessel and the left subclavian artery secondary branch artificial blood vessel are connected with the main body artificial blood vessel in a communicating manner. The quick connecting type four-branch artificial blood vessel is characterized in that left-hand threaded typeconnectors are respectively arranged at the far end of the left common carotid secondary branch artificial blood vessel and the far end of the left subclavian artery secondary branch artificial bloodvessel; and an intra-arterial infusion branch artificial blood vessel which communicates with the outer circulation of a connector is also arranged on the main body artificial blood vessel. The quickconnecting type four-branch artificial blood vessel disclosed by the invention is ingenious in structure and reasonable in design, so that the problem that in the prior art, in an aortic arch replacement operation, cerebral perfusion is insufficient, and nervous system complications are liable to generate can be solved; the quick connecting type four-branch artificial blood vessel can be quickly and reliably fixed, the situation that time is consumed for suturing is not needed, the operation is quick and convenient, the operation time can be greatly saved, the operation procedure difficulty isreduced, and the survival rate of a patient is increased.

Description

technical field [0001] The invention relates to an artificial blood vessel used in aortic arch replacement, in particular to a four-branch artificial blood vessel for quick-connect perfusion, which belongs to the technical field of medical device design. 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...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a quick-connect four-branch artificial blood vessel for perfusion. It is easy to cause nervous system complications, and can be fixed quickly and reliably without time-consuming sutures. The operation is fast and convenient, which can greatly save operation time, reduce the difficulty of operation, and improve the survival rate of patients
