Problems solved by technology

[0002] In traditional aortic replacement surgery, the main stem of the artificial vessel is fixed with the aortic vessel and the brachiocephalic vessel by sutures. It takes a long time and requires very high suturing techniques, and a long period of deep hypothermic circulatory arrest is required for suturing. Prolonged deep hypothermic circulatory arrest can cause irreversible damage to vital organs of the body
Traditional suturing techniques are also prone to bleeding complications that are difficult to control at the anastomosis, thereby reducing the success rate of the operation

Embodiment Construction

[0018] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0019] Such as Figure 1-2 A connection device for an artificial blood vessel for surgery and the aorta and brachiocephalic trunk vessel 21 shown includes a tubular main connection device 3, the inner side wall of the main connection device 3 is smooth, and the outer side of the tubular structure 31 is provided with grooves along the circumference of 33 32 and groove 34. The wall thickness of the tubular structure 31 is 0.5-1.5 mm, and the wall thickness refers to the wall thickness of the non-groove 32 . The material of the tubular structure 31 is a medical clean grad...

Abstract

The invention provides a device for connecting artificial blood vessels with aortas and innominate artery blood vessels in operations. The device comprises a connecting device body which is of a tubular structure, the inner side wall of the connecting device body is smooth, and a groove is formed in the outer side of the tubular structure along the circumference. According to the device, a traditional suturing technology can be replaced, the operation and deep hypothermic circulatory arrest time can be effectively shortened, and complications such as anastomosis bleeding are avoided, so that the blood consumption is greatly reduced, and the operation survival rate is increased.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, in particular to a connection device for an artificial blood vessel used in surgery, aorta and brachiocephalic trunk blood vessel. Background technique [0002] In traditional aortic replacement surgery, the main stem of the artificial vessel is fixed with the aortic vessel and the brachiocephalic vessel by sutures. It takes a long time and requires very high suturing techniques, and a long period of deep hypothermic circulatory arrest is required for suturing. Prolonged deep hypothermic circulatory arrest can cause irreversible damage to vital organs of the body. Traditional suturing techniques are also prone to bleeding complications that are difficult to control at the anastomosis, thereby reducing the success rate of the operation. Contents of the invention [0003] The object of the present invention is to design a connection device between the artificial blood vessel for surg...
