T pipe with needle

Abstract

The invention discloses a T pipe with a needle. The T pipe comprises a long arm (1) and a short arm (2), and one end of the long arm (1) is vertically connected with the middle of the short arm (2) toconstitute a T shape with a through pipe cavity; a through cut which extends in the axial direction of the short arm is formed in the side, opposite to the long arm (1), of the short arm (2) and communicated with the interior of the short arm, and the side face of the cut is in a sawtooth shape (5); a folding opening (4) which extends in the direction of the long arm is formed in the middle of the short arm (2); the end face of the other end of the long arm (1) is a slant face, and a tip end (6) is formed; an out-drawing line (7) is connected to the tip end (6) of the long arm (1), and the surgical needle (8) is connected to the other end of the out-drawing line (7). By means of the T pipe, the problems that the short arm is easily broken and drainage is unsmooth are solved; meanwhile, the T pipe changes the mode of drawing out the long arm, the surgical time is shortened, the surgical efficiency is improved, the total cut length of the common bile duct is reduced, and the pain of a patient is alleviated.

Description

technical field [0001] The invention belongs to auxiliary materials for operation, and in particular relates to a T tube. Background technique [0002] Laparoscopic T-tube drainage has a history of more than 20 years. The main functions of the T-tube are support, drainage, decompression of the biliary tract, observation of biliary bleeding, and removal of postoperative residual stones. At present, the T tube includes a long arm and a short arm, and the long arm is vertically connected with the middle part of the short arm to form a T-shape in which lumens communicate with each other. [0003] T-tube placement is necessary for most biliary tract exploration and biliary-enterostomy, but the safety of laparoscopic T-tube placement has been affected by many factors. Especially when placing the T tube in laparoscopic biliary anastomosis, use an electric knife to incise the anterior wall of the common bile duct, cut an incision on the short arm, fold the short arm and place the s...

AI Technical Summary

Problems solved by technology

This method has the following disadvantages: 1. The artificial cutting is uneven during the operation, and the short arm is easy to break

2. The short arm is easy to fit with the inner wall of the bile duct, and the drainage is not smooth

3. The total incision length of the common bile duct is much smaller than the length of the short arm, and it is difficult for the short arm of the T tube to enter the common bile duct, which brings inconvenience to the operation and increases the pain of the patient

4. The long arm is led out from the opening, and the incision needs to be sutured. The process is cumbersome, which increases the operation time, and the electric knife may cause damage to the biliary tract wall, and the thermoelectric effect is likely to cause extrahepatic biliary stricture.
