Description
Technical Field
The utility model relates to the technical field of medical equipment, concretely relates to supply hepatic portal vein puncture perfusion device.
Background
The liver perfusion is performed by infusing cold electrolyte solution such as lactated ringer's solution through portal vein or hepatic artery, and rapidly cooling the liver to make its central temperature reach 10-15 deg.C. Because the low temperature can reduce the metabolic needs of the liver, the tolerance of the liver parenchyma to temporary hypoxia is increased, and the time limit of hypoxic damage caused by blocking the hepatic blood flow at normal temperature is better overcome. When the tradition supplies the liver to obtain, explore the liver rapidly after opening the abdomen, know whether cirrhosis, liver occupy-place and serious fatty liver, the art person mentions the small intestine, ligate the mesentery by the assistant, cut pelvis population top peritoneum, show the abdominal aorta, cut its branching top antetheca, insert the Foley catheter of taking 2 ~ 3 side openings after the repacking to the near-end, the depth of insertion is gasbag to abdominal aorta opening plane top, inject 25ml normal saline into in the gasbag, pour into 0 ~ 4 ℃ lavage liquid. After completion of the abdominal aorta cannulation, portal perfusion was initiated. The assistant pulls the duodenum downwards, the operator cleft the head of the pancreas to find the root of the superior mesenteric vein behind the pancreas, cuts the anterior wall of the pancreas, inserts the self-made portal vein cannula with the depth of 2-3cm to prevent the insertion from going too deep to the portal vein branch, and ligates the splenic vein. After the ligation is performed, perfusion is started. This operation requires the main knife to be skilled to accurately locate the depth of the cannula and to quickly fix the cannula with the assistance of an assistant.
The problems that exist are that:

2. During the fixing process of the cannula, the traditional method of tying with wires also has influence on the installation time of the whole perfusion device according to different operation proficiency of operators.
3. The intubation tube has no length mark, and the operator can only judge the deep position of the intubation tube by experience, and when the intubation tube is too deep, the perfusion liquid flows to the top of the right half liver, so that insufficient perfusion of the left and right livers is easily caused.
4. Lack the device that prevents the palirrhea of liquid among the traditional pipeline that fills, liquid fills and relies on gravity factor to get into completely and supplies the liver, can arouse the palirrhea of perfusate because of various factors at any time in whole filling process, leads to filling speed to slow down.
