External member for reinfusion of bile into intestinal tract after in-vitro drainage

Abstract

The invention discloses an external member for reinfusion of bile into an intestinal tract after in-vitro drainage. The external member comprises a percutaneous transhepatic cholangial drainage (PTCD)assembly, a first in-vitro catheter, a one-way flow-guiding assembly, a second in-vitro catheter and a gastrointestinal implantation assembly; the PTCD assembly is used for passing through a first minimally invasive opening in the skin of the abdomen and the liver in vitro, then puncturing the biliary tract and draining the bile into the first in-vitro catheter; the one-way flow-guiding assemblyis used for guiding the bile to flow into the second in-vitro catheter from the first in-vitro catheter in a one-way mode; the gastrointestinal implantation assembly is used for passing through a second minimally invasive opening in the skin of the abdomen and the stomach in vitro, then being implanted into the intestinal tract and conducts reinfusion on the bile into the intestinal tract from thesecond in-vitro catheter; and the one-way flow-guiding assembly comprises a manual pump used for increasing the flowing speed of the bile. The bile can be obtained through drainage and discharged into the intestinal tract, the pain caused by stenting or oral administration of the bite is avoided, the life quality of a patient is improved, the feasibility is higher than that of stenting, the flowing speed and flow rate of the bile can be automatically adjusted by the patient through the manual pump in vitro, and operation is easy and feasible.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a kit for reinfusing bile into the intestinal tract after being drained outside the body. Background technique [0002] The biliary tract has the function of transporting bile from the gallbladder to the duodenum, promoting the absorption of fat, cholesterol and vitamins, and stimulating intestinal peristalsis. In clinical medicine, malignant tumors such as cholangiocarcinoma, liver cancer, pancreatic cancer, and metastatic cancer can cause malignant biliary obstruction, which prevents bile from being naturally discharged into the intestine. [0003] The prior art offers two surgical approaches to address bile delivery problems caused by malignant biliary obstruction. One method is to implant stents in the patient's bile duct and duodenal papilla respectively, and establish a pipeline passage in the abdominal cavity to connect the stents at both ends, so as to discharge bile into ...

AI Technical Summary

Problems solved by technology

One method is to implant stents in the patient's bile duct and duodenal papilla respectively, and establish a pipeline passage in the abdominal cavity to connect the stents at both ends, so as to discharge bile into the duodenum, and implant the stent into the bile duct The operation is more difficult, and it is easy to cause cholangitis, and the patient suffers a lot, and with the proliferation of cancer cells in the bile duct, the stent will still be squeezed and blocked, and the feasibility is poor; another method is: through PTCD (Percutaneous Transhepatic Cholangial Drainage , percutaneous hepatic biliary drainage) to drain bile to the outside of the body for storage in a drainage bag, and then take it orally into the intestinal tract. However, the experience of oral administration is extremely poor, and most patients cannot accept it, which affects the quality of life
