Three-cavity stomach tube used for Whipple operation

Abstract

The invention relates to the technical field of medical instruments, in particular to a three-cavity stomach tube used for a Whipple operation. The three-cavity stomach tube comprises a stomach pressure reduction tube (1), a nasal feeding tube (2) and a jejunum pressure reduction tube (4) which can slide up and down along a jejunum pressure reduction tube moving channel (3) in one side of the stomach pressure reduction tube. Stomach pressure reduction tube side holes (1.2) are formed in the lower end of the stomach pressure reduction tube. Scales are arranged on the outer wall of the nasal feeding tube (2), the lower end of the nasal feeding tube (2) is longer than the stomach pressure reduction tube (1), and nasal feeding tube side holes (2.2) are formed in the lower end of the nasal feeding tube (2). Jejunum pressure reduction tube side holes (4.2) are formed in the 10-20cm position of the lower end of the jejunum pressure reduction tube. The three-cavity stomach tube not only can suck liquid in the stomach, but also can suck pancreatic juices, bile and intestinal juices in the jejunum loop nearby the anastomotic stoma of the pancreas and the jejunum and the anastomotic stoma of the biliary tract and the jejunum, so that the jejunum nearby the anastomotic stomas is in an empty and shrunken state, tension in the jejunum loop is reduced, and the three-cavity stomach tube plays an important role in preventing the pancreatic fistula and biliary fistula after the operation. Meanwhile, the three-cavity stomach tube further can help a clinician to accurately judge the source of hemorrhage of the digestive tract after the operation, so that clinic treatment is instructed better.

Description

Technical field [0001] The invention relates to the technical field of medical instruments, and relates to a three-cavity gastric tube for Whipple operation. Background technique [0002] Pancreatic fistula and biliary fistula are one of the most common and serious complications after pancreaticoduodenectomy (Whipple operation). Leakage of pancreatic juice and bile due to rupture of jejunostomy and biliary-jejunostomy, followed by biliary-enteric juice activating trypsin in pancreatic juice, spilling into the abdominal cavity and eroding the anastomosis and surrounding tissues, causing severe abdominal infection, and even corroding large blood vessels leading to fatal The massive hemorrhage followed by multiple organ failure has become the main cause of death of patients after pancreaticoduodenectomy. Therefore, how to effectively prevent pancreatic fistula is an important link to ensure the success of the operation and reduce the mortality of patients; The incidence of pan...

Problems solved by technology

[0004] In order to solve the problem that the existing gastrointestinal decompression tube can only absorb the liquid in the stomach, but cannot directly absorb the liquid in the jejunal loop near the pancreaticojejunostomy and biliary-enteric anastomosis. The complete retention of liquid in the jejunal loop caused by gastrointestinal anastomotic obstruction caused by factors such as edema and stenosis of the mouth. The key is to attract the pancreatic juice, bile juice and intestinal juice in the jejunal loop near the pancreaticojejunostomy and biliary-enteric anastomosis most directly, so that the jejunum near the anastomosis is in an empty state, and the tension in the jejunal loop here is reduced. Prevention of postoperative pancreatic fistula and biliary fistula plays an important role; at the same time, the invention can also help clinicians make accurate judgments on the source of postoperative gastrointestinal bleeding, so as to better guide clinical treatment
