Hepatic portal blood flow blocking belt under filling type laparoscope

Technical Field

The utility model relates to a blood flow blocks takes technical field, specifically is a porta hepatis blood flow blocks area under filled peritoneoscope.

Background

The hepatic portal, a medical term, refers primarily to the location from which the nerves and lymphatic vessels of the liver pass. The median of the liver surface is slightly H-shaped, three grooves about 5cm long, wherein the transverse groove is located in the median of the liver surface, and the left and right hepatic ducts are in front of the liver, the left and right hepatic artery branches are in the middle, the left and right hepatic portal vein branches, the nerves and lymphatic vessels of the liver come in and go out, so the liver is called the hepatic portal. The exterior of these structures entering and exiting the portal is surrounded by the peritoneum, called the hepatic pedicle.
