Embodiment 1

[0038] Such as Figure 1-5 As shown, a T-shaped drainage tube with a growth factor coating includes a built-in T-tube 1, the built-in T-tube 1 is made of medical rubber material, the surface of the built-in T-tube 1 is coated with a growth factor coating 15, and the built-in T-tube 1 includes the long arm 11 and the short arm 12; the middle part of the short arm 12 is vertically fixed and communicated with the left end of the long arm 11, and the length of the central axis of the long arm 11 from the two ends of the short arm 12 is two to four centimeters. The short arm tip 13 is provided, and the middle part of the short arm 12 is provided with a folding opening 14 on the side away from the long arm 11. The folding opening 14 is triangular in shape, and the depth of the folding opening 14 extending toward the long arm 11 is less than or equal to two times the diameter of the short arm 12. one-third.

Embodiment 2

[0054] In the case that other parts are all the same as in Example 1, the difference between this example and Example 1 is that G-CSF can also use fibroblast growth factor (FGF), epidermal growth factor (EGF), vascular endothelial cell growth factor (VEGF) etc. instead.

Abstract

The invention discloses a T-shaped drainage tube with a growth factor coating, which comprises a built-in T-shaped tube, wherein the surface of the built-in T-shaped tube is coated with the growth factor coating, and the built-in T-shaped tube comprises a long arm and a short arm; a placing device for a T-shaped drainage tube with a growth factor coating is also disclosed, which comprises a main rod, a blocking piece a, a blocking piece b, a micro knob a, a micro knob b, a rotary nut and a guide wire. According to the invention, the length of the incision of the common bile duct can be furtherreduced while the convenience degree of placing the T-shaped tube into the common bile duct is improved. Important clinical significance is realized on shortening the operation time and reducing therisks of intraoperative biliary tract injury and postoperative biliary fistula. Meanwhile, cell growth factors introduced to the surface of the material by the T-shaped drainage tube are physically embedded in a biomacromolecule coating, so that sinus tract formation is induced and promoted, and the T-shaped drainage tube has important clinical application value and wide application prospect for reducing postoperative complications and the like.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a T-shaped drainage tube with a growth factor coating and a placement device thereof. Background technique [0002] At present, laparoscopic cholecystectomy + intraoperative common bile duct exploration + T-tube external drainage has become the main method for the treatment of patients with choledocholithiasis. T-tube external drainage helps to prevent cholestasis, reduce the pressure of the biliary system, reduce postoperative complications such as bile leakage and biliary stricture, and facilitate cholangiography and removal of residual stones through the T-tube sinus. Therefore, T-tube external drainage is widely used in hepatobiliary surgery. [0003] At present, the T-tube used clinically is a T-shaped latex tube. [0004] When placing the T-tube under laparoscopy, first cut the anterior wall of the common bile duct with an electric knife, then cut a folded opening in the mi...
