Technical Field
The utility model relates to an imbedding device for surgical operation, in particular to an intraoperative visual biliary tract stent imbedding device.
Background
Common bile duct stones, ampulla tumors and other diseases cause common bile duct obstruction and bile duct expansion above the obstruction part, and further cause obstructive jaundice. Once obstructive jaundice occurs in a patient, surgical treatment is often needed to relieve biliary obstruction and keep bile drainage smooth. For finding that the tumor has distant metastasis after probing in the operation or is more serious than preoperative prediction, no operation can be performed for radical treatment, surgeons often only perform the palliative operations of tumor biopsy, T tube placement or cholangiointestinal drainage and the like, and some surgeons select percutaneous liver puncture drainage (PTCD) under the guidance of B ultrasound or endoscopic downlink biliary stent implantation to relieve jaundice. However, no matter the T-tube row is placed for permanent external drainage or biliary-enteric anastomosis internal drainage, or the PTCD is performed after operation or the endoscopic biliary stent implantation is performed, there are certain disadvantages, which affect the treatment effect of the patient, and mainly appear as follows: the T-shaped tube is a foreign body, discomfort can be brought to a patient, and meanwhile, the water electrolyte is disordered and the digestive function is weakened due to the loss of a large amount of bile, so that the life quality of the patient is seriously affected; 2. the damage and risk of the cholangiointestinal drainage are large, and the natural digestive passage needs to be changed; 3. the PTCD after operation needs to be subjected to secondary trauma, the PTCD externally drains, so that a large amount of bile is lost, water electrolyte is disordered, the digestion function is weakened, and the drainage tube is a foreign body, so that discomfort and infection of a patient can be caused, and the life quality is reduced; 4. the biliary stent implantation under the postoperative endoscope needs to suffer from secondary trauma, damage oddis sphincter and also complications of pancreatitis, hemorrhage and other risks. Therefore, for obstructive jaundice, if a tumor is found to have no chance of radical treatment during operation, no matter which palliative treatment method is adopted, a satisfactory treatment effect cannot be achieved.
