Description

Be used for sutured stay tube of common bile duct I phase

Technical Field

The utility model relates to the field of auxiliary medical instruments, in particular to a support tube for I-stage suturing of common bile duct.

Background

Common bile duct stone patient, the operation mode commonly used now generally is that peritoneoscope common bile duct opens and carries out common bile duct notched processing again after the stone is got to the choledochoscope again, common bile duct notched processing mode has to settle T pipe drainage or common bile duct and does the I phase and sew up, keeping somewhere of T pipe brings certain inconvenience for patient's life, nursing, T pipe slippage risk still exists, can arouse the gall-leak again when pulling out the T pipe moreover, the patient takes a tub of time long, the time extension of being in hospital. And then the laparoscopic common bile duct exploration one-stage suture operation becomes a feasible operation mode for minimally invasive treatment of cholelithiasis complicated by extrahepatic bile duct calculi. Although the operation mode has the advantages of small wound, light pain, quick recovery, short hospitalization time and the like; it can relieve the pain of patients, save the hospitalization time and cost, but also has the complications of biliary leakage, residual calculus after operation, hemorrhage, bile duct stenosis and the like. Particularly, in the stage I suturing process, due to objective reasons such as technical level of doctors, conditions of a patient's own common bile duct and the like, when the stage I suturing is performed, benign biliary stricture caused by suturing to a lateral bile duct is caused, the benign common bile duct stricture may cause repeated cholangitis and obstructive jaundice and the like of the patient, and a serious patient needs to perform an operation again to perform the suturing again to the common bile duct. Some doctors in clinic also use the existing silica gel urinary catheter with holes, and suture is assisted by putting the silica gel catheter into the common bile duct, but certain risks exist: the support tube is easy to break in hollow tube operation, the support tube is left in the sutured common bile duct due to the fact that the support tube is made to shift after the support tube is broken, the sutured common bile duct needs to be cut off, the support tube left in the support tube is taken out, then suturing of the common bile duct is conducted, and operation time is delayed. Secondly, a section of the silicone tube is cut by itself, the section of the silicone tube is flat and uneven, and the inner wall of the common bile duct is easy to damage. Therefore, a support tube which can effectively assist in the I-stage suturing of the common bile duct is urgently needed to effectively prevent the stenosis of the common bile duct caused by the suturing.

SUMMERY OF THE UTILITY MODEL

The utility model solves the problem of how to reduce common bile duct stenosis possibly caused in the common bile duct stage I suturing process, and aims to provide a support tube for common bile duct stage I suturing, which is placed in an incised common bile duct during the common bile duct stage I suturing process to support the inner wall of the common bile duct, so that the inner wall of the common bile duct is more obviously distinguished, and the arc-shaped structures of the outer walls at the two ends of the support tube are not easy to damage the inner wall of the common bile duct, thereby avoiding causing secondary damage, assisting the common bile duct stage I suturing, avoiding the benign bile duct stenosis caused by suturing to the bile duct on the side wall, arranging a silica gel traction tubule outside the support tube, and facilitating the support tube to be taken out after the suturing is finished.
