Artificial blood vessel for over-turning anastomosis

Abstract

The present invention provides an artificial straight blood vessel for over-turning anastomosis. The artificial straight blood vessel for over-turning anastomosis consists of an annular line anastomosis section, a vertical line connecting section and an annular line extension section, the vertical line connecting section is respectively connected with the annular line anastomosis section and the annular line extension section, the annular line anastomosis section is turned over outwards, two sections of blood vessels of the annular line anastomosis section and the vertical line connection section are tightly jointed after being turned over, and the whole shape of the artificial blood vessel is in a turned-over cuff shape. The artificial blood vessel is woven by adopting a polyurethane material, and an inside and an outside of the blood vessel both contain albumin coatings. The artificial blood vessel is simple to manufacture, non-magnetic, not narrow inside, good in longitudinal line expansion, complete in models, and suitable for people of various body types, and especially contains small diameter models. The artificial straight blood vessel can continuously suture a plurality ofstitches, realizes fast and efficient suturing, is not easy to cause anastomotic stenosis and convenient to complete a blood vessel replacement operation, has good hemostasis and compression effects,obviously reduces a bleeding incidence rate of anastomotic stoma, ensures anastomotic quality, and has simple and convenient operation and exact effects.

Description

technical field [0001] The invention belongs to the field of implantable medical devices, in particular to an implantable artificial blood vessel, in particular to an artificial blood vessel for flipping and anastomosis, which is an artificial blood vessel used for surgically replacing a diseased blood vessel when a diseased blood vessel occurs in a human body. A flipped artificial blood vessel that can help surgeons efficiently complete vascular anastomosis. Background technique [0002] Blood vessels are the channels through which organisms transport blood, and can be divided into arteries, veins and capillaries. Arteries carry blood from the heart to body tissues, veins carry blood from tissues back to the heart, and capillaries connect arteries and veins. The walls of the aorta and aorta are thick and rich in elastic fibers, which are expandable and elastic. When there is a problem with the artery, especially when there is a problem with the large artery, such as aorti...

Problems solved by technology

[0003] At present, most of the commonly used artificial straight blood vessels that can be used for the treatment of aortic dissection rely on the import, and the main design is to adopt the telescopic design of the ring pattern ( figure 1 2), the ductility is good, but it is difficult to turn over, and the shape is not controlled after turning over, it is difficult to compress and insert into the human blood vessel cavity, and it is difficult to unfold and fit the human blood vessel well after being inserted into the blood vessel. The procedure itself is likely to cause damage to the artificial vessel wall and cause postoperative bleeding

Therefore, the current artificial blood vessels are sutured by the face-to-face suture method of non-reversal anastomosis. Due to the poor exposure of the visual field, the relative position of the artificial blood vessel and the human blood vessel needs to be adjusted frequently during the suturing process. The uneven pressure leads to a long suture time for one port. , and only one suture can be sutured, the bleeding probability is significantly increased, and bleeding or severe bleeding often occurs in the suture area. Time increases the incidence of postoperative complications, although the physicians who can perform such operations are already extremely experienced doctors

In addition, the current imported artificial blood vessels are mainly designed for European and American populations, so the lumen size of the blood vessels is large, while some Chinese people are not big in size, such large artificial blood vessels are not suitable for them
