Problems solved by technology

The disadvantage of various traditional retractors is that the shape does not match the hypertrophic square lobe and cannot effectively fix the square leaf of the liver; the surface of the retractor is smooth, and the friction between the retractor and the surface of the liver is small when the force is applied, which can easily cause sliding displacement between the retractor and the liver surface , poor exposure of the porta hepatis

Abstract

The invention discloses a porta hepatis retractor for biliary atresia porta hepatis intestinal anastomosis. The porta hepatis retractor comprises a retractor handle, a front retractor plate and a rearretractor plate, wherein the front retractor plate is arranged on the upper portion of one end of the retractor handle; the front retractor plate is perpendicular to the retractor handle; the rear retractor plate is arranged on the lower portion of the other end of the retractor handle; the rear retractor plate is perpendicular to the retractor handle; and the retractor handle, the front retractor plate and the rear retractor plate are of an integrated structure. The shape of the retractor is designed according to the form of the biliary atresia hypertrophic liver quadrate lope, hollow partsare arranged in the front retractor plate and the rear retractor plate, or the top end of the front retractor plate is provided with a protrusion bent towards one side of the retractor handle, and thebottom of the rear retractor plate is provided with a protrusion bent towards one side of the retractor handle, so that the stability of liver tissue traction is improved, and the optimal surgical exposure effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, in particular to a hepatic portal retractor for biliary atresia hepatic portal anastomosis. Background technique [0002] Biliary atresia is a common congenital malformation in pediatric surgery. The pathological change is that the intrahepatic bile ducts are thin and cannot effectively drain intrahepatic bile out of the liver. The most critical part of the operation is the anatomy of the fibrous mass of the hilum, resection and transection close to the liver surface, and anastomosis of the jejunum and the hilum. Because the hepatic hilum reaches deep behind the portal vein, and the square lobe in front of the hepatic hilum is hypertrophic and hypertrophic, it is very difficult to expose the hepatic hilum, which affects the operation. The effect of the operation is not good, and the success rate is only 40%-60%. Clear and accurate exposure of the hepatic porta is the key to the succ...
