Bile reinfusion kit after extracorporeal drainage

Abstract

The invention discloses a kit for reinfusing bile into the intestinal tract after extracorporeal drainage, comprising a PTCD component, a first extracorporeal catheter, a one-way guide component, a second extracorporeal catheter and a gastrointestinal implant component; the PTCD component is used for draining bile from the outside The first minimally invasive opening through the abdominal skin, posthepatic puncture of the biliary tract, and drainage of bile to the first extracorporeal catheter; the unidirectional diversion assembly is used to unidirectionally divert bile from the first extracorporeal catheter to the second extracorporeal catheter; gastric The intestinal implant assembly is used to implant the intestine from the outside through the second minimally invasive opening of the abdominal skin, retrogastrically, and reinfuse bile from the second external catheter into the intestine; Pump. The invention can drain bile and discharge it into the intestinal tract, avoiding the pain caused by stent surgery or taking bile orally, and improving the quality of life of patients. Compared with stent surgery, the feasibility is higher, and patients can use the manual pump outside The bile flow rate and flow can be adjusted by itself, and the operation is simple 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
