C-shaped wrapping type pancreatic fistula resistant drainage device

Abstract

The invention relates to a C-shaped wrapping type pancreatic fistula resistant drainage device. The C-shaped wrapping type pancreatic fistula resistant drainage device is characterized by comprising adevice main body and a multi-cavity tube, wherein the device main body comprises a first curve segment body and a second curve segment body, one end of the first curve segment body and one end of thesecond curve segment body are connected and integrally shaped, the other end of the first curve segment body and the other end of the second curve segment body are in dismountable connection, and after the other end of the first curve segment body and the other end of the second curve segment body are connected, an annular drainage channel is formed by inner walls of the first curve segment bodyand the second curve segment body; and a through hole is formed in the device main body, and one end of the multi-cavity tube is connected with the through hole. In the use process of the device, whenleaking, pancreatic liquid can be drained by the through hole of the drainage channel to the multi-cavity tube to be drained as soon as possible, so that drainage of the leaked pancreatic liquid is convenient, and drainage efficiency and drainage reliability are improved; and besides, the situation that the leaking pancreatic liquid is in contact with surrounding tissue blood vessels to cause corrosion can be avoided. In addition, the multi-cavity tube is used for realizing closed type cycle flushing, so that flushing liquid cannot leak to an abdominal cavity, and the safety is improved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a C-shaped wrapping anti-pancreatic fistula drainage device. Background technique [0002] Pancreatic fistula is an abnormal channel between the pancreatic ductal epithelium and other epithelial surfaces containing enzyme-rich fluid originating from the pancreas. In 2005, the International Pancreatic Fistula Research Group (ISGPF) defined pancreatic fistula as the amylase concentration in peritoneal drainage fluid 3 days or more after surgery was more than 3 times higher than the upper limit of normal plasma amylase concentration, and corresponding clinical manifestations must be present at the same time. According to the clinical impact of pancreatic fistula, it is divided into grade A: transient, no clinical symptoms, only drainage fluid amylase elevation, no obvious imaging changes, also known as biochemical fistula; grade B: clinical symptoms such as abdominal pain, fever, vomi...

Problems solved by technology

[0005] Disadvantage 1: The various drainage tubes currently used in clinical practice can only be drained out of the body through the drainage tube after the pancreatic juice leaks into the surrounding tissues, causing the pancreatic juice to stay or accumulate in the abdominal cavity, which directly contacts and corrodes the surrounding tissues and blood vessels. Accumulated, leading to serious complications such as infecti...
