Embodiment 1

[0043] Such as Figure 1-9 As shown, a suture-free artificial blood vessel device includes a support ring 1, an artificial blood vessel 2 and an eversion section 21; the artificial blood vessel 2 is provided with at least one eversion section 21; the support ring 1 is set along the eversion section 21 On the artificial blood vessel 2 , and, the everted section 21 is turned outward and wraps around the support ring 1 .

[0044] The artificial blood vessel can be abdominal aorta, ascending aorta, aortic arch or descending thoracic aorta. When the artificial blood vessel is the ascending aorta or the aortic arch, the first branch blood vessel 3 , the second branch blood vessel 4 , the third branch blood vessel 5 and the fourth branch blood vessel 6 can be arranged thereon.

[0045] Way of working:

[0046]The support ring 1 is set on the artificial blood vessel 2, and a section of valgus section 21 is reserved outward, and the valgus section 21 is turned outward and wrapped in ...

Embodiment 2

[0050] Compared with Embodiment 1, the difference lies in that a material for making the support ring is provided.

[0051] The support ring 1 is made of titanium mesh. The material of the titanium mesh is titanium or titanium alloy. Titanium is close to human bones, has good biocompatibility to human tissues, and has no toxic and side effects. Titanium has the characteristics of light weight, low elastic modulus, non-magnetic, non-toxic, corrosion resistance, high strength and good toughness.

Embodiment 3

[0053] Compared with Example 2, the difference lies in that a structural form of the titanium mesh is given.

[0054] The titanium mesh is provided with a plurality of mesh holes 11 . It can help reduce the weight of titanium mesh.

[0055] The valgus segment 21 is turned outwards to wrap the supporting ring 1 . The supporting ring is made of titanium mesh, and the titanium mesh is provided with a plurality of mesh holes 11 .

[0056] When necessary, suturing can be carried out at the bridges between the artificial blood vessel and the abdominal aorta, ascending aorta, aortic arch or descending thoracic aorta. The suture thread passes through another mesh, and then passes through the everted segment and the blood vessel in turn, so as to repeat the loop suture. When suturing, the innermost artificial blood vessel is not penetrated, avoiding needle hole bleeding, and connecting the supporting ring, the artificial blood vessel and the blood vessel.

Abstract

The invention discloses a suture-free artificial blood vessel device which comprises a supporting ring, an artificial blood vessel and an eversion section. The artificial blood vessel is provided with at least one eversion section. The supporting ring is arranged on the artificial blood vessel in a sleeving mode along the eversion section, and the eversion section is turned outwards and wraps the supporting ring. The supporting ring wrapped by the artificial blood vessel can be inserted into a blood vessel, so that the artificial blood vessel and the blood vessel are bridged. The bridging position is bound and fixed through a ligation binding line, so that suture is avoided. The support ring is isolated from the blood vessel by the artificial blood vessel, so that direct contact between the support ring and blood is avoided.

Description

technical field [0001] The invention relates to a suture-free artificial blood vessel device. Background technique [0002] Vascular disease is mainly divided into arterial disease and venous disease. The most common venous diseases are varicose veins and venous thrombosis. Common arterial diseases include: arterial embolism, arterial stenosis, aneurysm, etc. Among them, aneurysm is a large vessel disease that seriously threatens the safety of patients. [0003] In particular, acute Stanford type A dissection in aneurysms is the most dangerous type, with rapid onset, rapid progression, and extremely high lethality. Without surgical treatment, the 48-hour mortality rate is close to 50%, and the 30-day mortality rate is as high as 90%. [0004] At present, for the dissection involving the aortic arch, Sun's operation has become the standard operation method for the treatment of such diseases. In the operation, the ascending aorta and root are first treated under extracorpo...
