Problems solved by technology

[0003] In traditional surgical techniques, when doctors perform artificial blood vessel replacement operations, the connection of two artificial blood vessels is usually sutured, which generally requires dozens to hundreds of stitches. Simply suturing the anastomosis of two artificial blood vessels requires ten. More than 10 minutes, the operation takes a long time, and in cardiovascular surgery, especially heart and great vessel surgery, it will have adverse effects on the recovery of blood circulation, health and even life of the patient.

Embodiment 1

[0031] like figure 1 As shown, this embodiment discloses a surgical aortic arch stent artificial blood vessel structure, including a first artificial blood vessel 1, a connecting ring 2, a second artificial blood vessel 3, a threading hole 4, a first branch 5, a second branch 6, The first bifurcated portion 7, the second bifurcated portion 8, the first surgical wire 9a, and the second surgical wire 9b.

[0032] A connecting ring 2 is nested on the outside of one side of the first artificial blood vessel 1, and a reflexed part is left between the connecting ring 2 and the end of the first artificial blood vessel 1 on this side, and the reflexed part wraps the connecting ring to form Composite end, one end of the second artificial blood vessel is nested on the composite end to form a connection part; a threading hole 4 is provided on the circumferential side wall of the connection ring;

[0033] A first branch 5 and a second branch 6 are provided on the periphery of the first a...

Embodiment 2

[0045] like figure 2 As shown, this embodiment is the same as Embodiment 1. The difference is that, at the proximal end of the surgical aortic arch stent artificial vascular structure ( figure 2 (middle left side) is provided with a second connecting ring 10 for connecting with the artificial blood vessel 11 at the proximal end. The structure of the second connection ring 10 is the same as that of the connection ring 2, and the connection method is the same as the connection method between the first artificial blood vessel and the second artificial blood vessel in the first embodiment. The only difference is that the connections are in different places.

[0046] The application of this embodiment requires an additional step, that is, to connect the connecting ring 10 with the artificial blood vessel at the proximal end.

Embodiment 3

[0048] This embodiment is the same as Embodiment 1. The difference is that a second connecting ring is provided at the proximal end of the artificial blood vessel structure of the aortic arch stent for surgery, and is used for connecting with the ascending aortic blood vessel. The second connecting ring has the same structure as the connecting ring. The only difference is that the connections are in different places.

[0049] The application of this embodiment requires an additional step of connecting the connecting ring with the ascending aorta.

Abstract

The invention discloses an arcus aortae stent graft vascular structure for the department of surgery. The structure comprises a first artificial blood vessel, a connecting ring and a second artificial blood vessel. The connecting ring is embedded into the exterior of one side of the first artificial blood vessel. A reflection portion is reserved at the connecting ring and the end of the first artificial blood vessel. The reflection portion is turned outwards to wrap the connecting ring to form the compound end. One end of the second artificial blood vessel is embedded at the compound end to form a connecting portion. A threading hole is formed in the peripheral side wall of the connecting ring. A first branch and a second branch are arranged on the periphery of the first artificial blood vessel. The first branch comprises a first forked portion for being connected with an innominate artery and a second forked portion for being connected with the left common carotid artery. The second branch is connected with a pump blood vessel and then disconnected with the left subclavian artery. The second artificial blood vessel is the stent graft artificial blood vessel, and the far end of the second artificial blood vessel is used for being connected with the thoracic descending aorta.

Description

technical field [0001] The invention designs a medical device, especially a surgical aortic arch stent artificial blood vessel structure and its application in the artificial blood vessel. Background technique [0002] Artificial blood vessels are substitutes for many severely stenotic or occlusive blood vessels. Most of them are made of polymer synthetic materials such as nylon, polyester, and polytetrafluoroethylene. They are suitable for the replacement and reconstruction of blood vessels throughout the body. Large and medium-caliber artificial blood vessels The clinical application has achieved satisfactory results. [0003] In traditional surgical techniques, when doctors perform artificial blood vessel replacement operations, the connection of two artificial blood vessels is usually sutured, which generally requires dozens to hundreds of stitches. Simply suturing the anastomosis of two artificial blood vessels requires ten. More than 10 minutes, the operation takes a ...
