Referring to fig. 1, the four-bifurcation artificial blood vessel with the skirt comprises a main tube 100, a spare tube 101 and three bifurcated tubes 102, wherein the skirt 110 is arranged on the outer wall of the main tube 100, the three bifurcated tubes 102 are arranged on the skirt 110, and the spare tube 101 and the three bifurcated tubes 102 are respectively communicated with the main tube 100. When the aortic artery partition device is used, the wall of an aortic artery is firstly cut open, the main pipe 100 is placed, the near end and the far end of the main pipe 100 are respectively anastomosed with the near end and the far end of an ascending aorta, then the three bifurcated pipes 102 are respectively anastomosed with a innominate artery, a left common carotid artery and a left subclavian artery, the area of the wall of the dissected aortic artery is larger, then the wall of the aortic artery is wrapped on the main pipe 100, the edge of the wall of the aortic artery is sewed with the skirt 110, and the three bifurcated pipes 102 are arranged on the skirt 110, so that the problem that the root of a common four-bifurcated artificial blood vessel is very hard and narrow due to the existence of the root of the bifurcated blood vessel, the autologous aorta wrapping and shunting are inconvenient to use due to the existence of the root of the bifurcated blood; then, a pericardium sheet is used or the wrapped aortic vessel wall is directly communicated with the right auricle in an anastomotic manner according to requirements, so that blood seeped from the anastomotic position of the near end and the far end of the bifurcated artificial vessel can be shunted into the right atrium by permeating into the right auricle, bleeding and blood seepage from the anastomotic position of the near end and the far end of the bifurcated artificial vessel into the body are reduced, and wrapping and shunting are also facilitated. The standby tube 101 is arranged and can be used for extracorporeal circulation arterial intubation or bypass to descending aorta, and when the standby tube 101 is not needed, the standby tube 101 can be closed by suturing to prevent blood from bleeding into the body from the standby tube 101.

In a further preferred embodiment, the three bifurcated pipes 102 are juxtaposed from left to right on the skirt 110, and the spare pipe 101 is disposed beside the skirt 110. As the innominate artery, the left common carotid artery and the left subclavian artery in the human body are generally arranged side by side from left to right, the three bifurcated tubes 102 are arranged side by side from left to right on the skirt 110, so that the three bifurcated tubes 102 are convenient to be respectively anastomosed with the innominate artery, the left common carotid artery and the left subclavian artery.

Further, in a preferred embodiment, the branch pipe 102, the main pipe 100 and the reserve pipe 101 are disposed to be perpendicular to each other in pairs. The bifurcated pipe 102, the main pipe 100 and the spare pipe 101 are arranged in a mutually perpendicular mode in pairs, so that three bifurcated pipes 102 can be conveniently inosculated with a innominate artery, a left common carotid artery and a left subclavian artery respectively, meanwhile, when the spare pipe 101 needs to be used, the spare pipe 101 faces a doctor, and the spare pipe 101 can be conveniently used for extracorporeal circulation arterial intubation or can be bridged to a descending aorta.

Further preferably, the diameter of the main pipe 100 is 2.4-2.8 cm; the length range of the main pipe 100 is 25-35 cm.

Further preferably, the diameter ranges of the spare pipe 101 and the three branch pipes 102 are both 0.8-1.2 cm; the length range of the spare pipe 101 and the length range of the three branch pipes 102 are both 10-15 cm. During production, a manufacturer can select to produce a plurality of skirt four-branch artificial blood vessels with different sizes and lengths, and a doctor can select the four-branch artificial blood vessels with proper sizes according to requirements.

Further preferably, the width of the skirt 110 is 2.8-3.2 cm; the length range of the skirt edge 110 is 5.8-6.2 cm. The skirt 110 can be made into an oval shape, which will not scratch the wall of the aorta vessel, and at the same time, facilitate the sewing of the wall of the aorta vessel to the skirt 110.

Further in a preferred embodiment, the main tube 100, the reserve tube 101, the bifurcation tube 102 and the skirt 110 are made of a medical polymer material. The main tube 100, the reserve tube 101, the bifurcation tube 102 and the skirt 110 are made of medical polymer materials, such as polyurethane, silicone rubber, polyester fiber, polyvinylpyrrolidone, polyetheretherketone, polymethylmethacrylate, polyvinyl alcohol, polylactic acid, polyethylene, and the like.

While the preferred embodiments of the present invention have been described in detail, it will be understood by those skilled in the art that the invention is not limited to the details of the embodiments shown, but is capable of various modifications and substitutions without departing from the spirit of the invention.
