Artificial blood vessel

Abstract

The invention provides an artificial blood vessel. The artificial blood vessel comprises a lower cavity vessel, a liver right vessel, a liver middle vessel and a liver left vessel, wherein the lower cavity vessel is provided with a first port located at the upper part and a second port located at the lower part, the first port is in coincidence and communication with the upper part stump of liverinferior vena cava or a right auricle, and the second port is in coincidence and communication with the lower part stump of the liver inferior vena cava; and the upper end of the liver right vessel, the upper end of the liver middle vessel and the upper end of the liver left vessel communicate with the lower cavity vessel, the lower end of the liver right vessel is in coincidence and communicationwith the stump of a liver right vein, the lower end of the liver middle vessel is in coincidence and communication with the stump of a liver middle vein, and the left end of the liver left vessel isin coincidence and communication with the stump of the liver left vein. Therefore, when a non in situ hepatectomy is performed, whole excision from the right auricle to a second hepatic portal in theliver is realized. The problem that in the prior art, a single-cavity straight artificial blood vessel is adopted, so that whole excision from the right auricle to the second hepatic portal in the liver cannot be realized in the process in a surgery, can be solved.

Description

Technical field [0001] The invention relates to the field of medical equipment, in particular to an artificial blood vessel. Background technique [0002] At present, the temporary and replacement posterior inferior vena cava artificial blood vessel used in non-original hepatectomy (especially autologous liver transplantation and semi-ex vivo liver resection) is a single-lumen straight artificial blood vessel, which cannot be used with the right liver. The vein, middle hepatic vein, and left hepatic vein are anastomosed. Therefore, the whole resection from the right atrial appendage to the second hepatic hilum in the liver cannot be achieved during the actual operation of orthotopic liver resection. The existing single-lumen straight artificial blood vessel cannot be accepted. The damaged diaphragm is repaired, and the small resection area of ​​the diaphragm also affects the efficiency of the operation. Summary of the invention [0003] The main purpose of the present invention i...

Problems solved by technology

[0003] The main purpose of the present invention is to provide an artificial blood vessel to at least solve the problem that the single-lumen straight artificial blood vessel used in the prior art cannot be completely resected from the right atrial appendage to the second hilum of the liver during the operation
