Embodiment Construction
[0023] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0024] to combine Figure 1-2 , the artificial blood vessel of this embodiment includes four bifurcations 5 , an outer tube 1 and an inner tube 2 . Both the outer tube 1 and the inner tube 2 are made of medical polymer materials, such as polyurethane, silicone rubber, polyester fiber, polyvinylpyrrolidone, polyether ether ketone, polymethyl methacrylate, polyvinyl alcohol, polylactic acid, polyethylene etc. The diameter of the outer tube 1 is 16-30mm. The diameter of the inner tube 2 is...

The invention provides an artificial blood vessel. The artificial blood vessel comprises a quadrifurcate part and a bracket, and further comprises an outer pipe and an inner pipe, wherein one end of the inner pipe is connected with the quadrifurcate part, a clamp ring is arranged on the inner pipe, the bracket is fixed inside the inner pipe, one end of the outer pipe is fixed to the inner pipe, a tightening line is arranged at the end part of the outer pipe, and when the tightening line is tensioned, the end part of the outer pipe is tightened till compressing the inner pipe. For the artificial blood vessel, the inner pipe is placed at the blood vessel defect part, and the clamp ring is placed in the inner wall of the blood vessel, so that the inner pipe is temporarily fixed in the blood vessel; the outer pipe is positioned on the outer wall of the blood vessel, the end part of the outer pipe is placed at the outer end of the inner pipe, and the tightening line is tensioned, so that the end part of the outer pipe is tightened till the caliber of the end part of the outer pipe is smaller than the diameter of the clamp ring, then the tightened tightening line and the clamp ring form a locking structure, then the inner pipe and the outer pipe are fixed to the blood vessel, and then the artificial blood vessel and the blood vessel are rapidly connected together, and finally, the operation time of the surgery is shortened.
Description
technical field [0001] The invention relates to the field of medical instruments, in particular to an artificial blood vessel. technical background [0002] Arterial vascular injury, arterial vascular disease, or organ autotransplantation often require artificial blood vessels to replace their own blood vessels. Existing artificial blood vessels all adopt medical macromolecular materials to be braided into tubular structures. During the operation, the blood flow of the own blood vessel that is anastomosed with the artificial blood vessel is first blocked, and then the artificial blood vessel is embedded in the defect of the blood vessel. First, one end of the artificial blood vessel is sutured to the blood vessel; However, blocking the blood flow will cause ischemia and hypoxia problems for the organs dominated by the arteries. For the organs that are more sensitive to ischemia and hypoxia, prolonged ischemia may affect its function, and severe cases may lead to organ ische...
