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.
