Biliary tract inner support drainage tube

Abstract

The invention relates to a biliary tract inner support drainage tube and belongs to medical apparatuses and instruments. The biliary tract inner support drainage tube comprises a support drainage tube and a guiding wire placed in the support drainage tube. One end of the support drainage tube is in an oblique-face shape. Side through holes are evenly distributed in the tube wall of the support drainage tube. The support drainage tube and the guiding wire are used for replacing a T-shaped tube for being used in operative treatment of a patient with choledocholithiasis, after the choledocholith is fully taken out, the primary suture of the common bile duct is carried out without placing the traditional T-shaped tube, so operation time is shortened, operation difficulty is lowered, operation equipment cost is lowered, patient hospital staying time is shortened, hospital staying cost is lowered, postoperative complications are reduced, the patient can be recovered quickly, what is more important, the support drainage tube can be excreted out of the body along with excrement in about one week after operation, so that the patient does not need to suffer from the pain caused by long-term T-shaped tube retention, a series of complications caused by T-shaped tube placing are completed avoided, scars after operation become small, and accordingly the operation becomes more minimally invasive. If the biliary tract inner support drainage tube can be used widely and clinically, great benefit will be brought to the patient.

Description

technical field [0001] The invention relates to a supporting drainage tube in the biliary tract, which belongs to medical equipment. Background technique [0002] At present, after surgical treatment of patients with choledocholithiasis, a T-shaped tube is placed in the common bile duct and taken out of the body after the common bile duct stone is removed. The T-tube can usually be removed after 1-2 months after surgery. This method is not only difficult to operate, but also A series of complications such as bile leakage and bleeding are prone to occur after the operation. Moreover, the indwelling of the T-shaped tube for 1-2 months after the operation will also bring the following complications: ①It may cause bile duct damage and bleeding; ②The drainage of the T-shaped tube will cause a large amount of bile and electrolyte loss, which will affect the recovery of the patient and prolong the recovery of the patient. ③The T-shaped tube itself is a foreign body, which may indu...

[0002] At present, after surgical treatment of patients with choledocholithiasis, a T-shaped tube is placed in the common bile duct and taken out of the body after the common bile duct stone is removed. The T-tube can usually be removed after 1-2 months after surgery. This method is not only difficult to operate, but also A series of complications such as bile leakage and bleeding are prone to occur after operation

Moreover, the indwelling of the T-shaped tube for 1-2 months after the operation will also bring the following complications: ①It may cause bile duct damage and bleeding; ②The drainage of the T-shaped tube will cause a large amount of bile and electrolyte loss, which will affect the recovery of the patient and prolong the recovery of the patient. ③The T-shaped tube itself is a foreign body, which may induce the re-formation of choledocholithiasis; ④The long-term placement of the T-shaped tube may compress the duodenum or transverse colon and cause intestinal leakage; ⑤T-shaped tube Shedding may lead to biliary peritonitis; ⑥Tube removal may lead to common bile duct stenosis and obstructive jaundice; ⑦After T-tube removal, the abdominal wall forms a sinus that is difficult to heal
