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] This embodiment discloses a simple artificial blood vessel quick-connecting ring, which includes a cylindrical body 2, and threading holes 3 are provided on the circumferential side wall of the body. There are 3 groups of threading holes on the connecting ring, one group at an angle of 120 degrees, two in each group, equally arranged on the circumferential side wall of the connecting ring, forming two parallel rings.

Embodiment 2

[0033] Such as figure 2 As shown, this embodiment discloses a simple artificial blood vessel quick connection structure, including an artificial blood vessel 1, a connecting ring 2 nested on one side of the artificial blood vessel 1, and a threading hole 3 is provided on the peripheral side wall of the connecting ring 2 . The diameter of the artificial blood vessel is equal to 30mm, the diameter of the connecting ring is equal to 30mm, the width of the connecting ring is 10mm, and the diameter of the connecting ring is the same as that of the artificial blood vessel. There are three groups of threading holes on the connecting ring, two in each group, which are evenly arranged on the circumferential side wall of the connecting ring to form two parallel rings.

Embodiment 3

[0035] Such as image 3 As shown, this embodiment discloses a simple artificial blood vessel quick connection structure, including a first artificial blood vessel 1 , a connecting ring 2 , a threading hole 3 , a reflexed part 4 , a second artificial blood vessel 5 and a surgical thread 6 . The diameter of the first artificial blood vessel is equal to 28 mm, the diameter of the connecting ring is equal to 28 mm, and the diameter of the second artificial blood vessel is 30 mm. The width of the connecting ring is 30mm. The diameter of the second artificial blood vessel 5 is slightly larger than the diameter of the first artificial blood vessel 1. The connecting ring 2 is nested outside one end of the first artificial blood vessel 1. The ring 3 is provided with three groups of threading holes 3, and each group of threading holes 3 is two holes, and the threading holes are equidistantly arranged on the circumferential side wall of the connecting ring 3, and the reflexed part 4 on ...

Abstract

The invention discloses a simple quick-connection structure for an artificial blood vessel. The simple quick-connection structure for the artificial blood vessel comprises the artificial blood vessel, one side of the artificial blood vessel is nested with a connecting ring and two or more pairs or rows of thread penetrating holes are formed in the side wall in the circumferential direction of the connecting ring. The diameter of the artificial blood vessel is smaller than or equal to 30 mm. The diameter of the connecting ring is smaller than or equal to 30 mm. The diameter of the connecting ring is equal to that of the artificial blood vessel. The two or more pairs of thread penetrating holes are evenly formed in the side wall in the circumferential direction of the connecting ring so as to be beneficial to firmly connecting the broken ends of two artificial blood vessels. The width of the connecting ring ranges from 10 mm to 35 mm. The two or more rows of thread penetrating holes are formed in the connecting ring, and two or more thread penetrating holes are in one row.

Description

technical field [0001] The invention designs a medical device, in particular a simple artificial blood vessel quick connection structure and its application in artificial blood vessels. 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 lon...
