Double-lumen T tube

Abstract

The invention discloses a double-lumen T tube which comprises a T tube body. The T tube body comprises a long-arm tube and a short-arm tube, the long-arm tube and the short-arm tube arranged at the front end of the long-arm tube are formed integrally, a lumen of the short-arm tube is communicated with a lumen of the long-arm tube, and a fixing ring is arranged on the inner wall, corresponding to the tail end of the lumen of the long-arm tube, of the short-arm tube. An inner tube with two ends open are arranged in the lumen of the long-arm tube, and the tail end of the inner tube penetrates out of the wall of the long-arm tube while the front end of the inner tube penetrates out of one end of the short-arm tube. A threading tube as long as the long-arm tube is arranged in the lumen of the long-arm tube, supporting rings coaxial to the threading tube are arranged at intervals on the inner wall of the threading tube, the threading tube is penetratingly provided with a movable string, the front end of the string penetrates out of the front end of the threading tube to be wound onto the fixing ring, and the tail end of the string penetrates out of the tail end of the threading tube to remain outside the long-arm tube. Due to the facts that the fixing ring is arranged in the short-arm tube of the double-lumen T tube and the threading tube is arranged in the long-arm tube, the string at the tail end can be pulled when the tube is pulled, then the arc short-arm tube is bent towards the center, and pains resulted from tube pulling can be alleviated for patients.

Description

technical field [0001] The invention relates to the technical field of medical catheters, in particular to a double-lumen T-tube. Background technique [0002] Bile duct stone removal and T-tube drainage are still the main operations for the treatment of biliary stones at present. However, necrotic and exfoliated biliary epithelial tissue, residual stones, blood clots and other biliary foreign bodies are often deposited in the bile duct due to poor postoperative drainage. As a result, the T tube cannot be removed on time in a small number of patients, and then choledochoscopy or EST is needed to solve it. Therefore, it is of great clinical significance to effectively prevent and remove foreign bodies such as regenerated or residual stones in the postoperative biliary tract and avoid secondary biliary obstruction while paying attention to removing stones during the operation. However, this type of T tube has a single structure, limited function, long indwelling tube time and...

AI Technical Summary

Problems solved by technology

However, this type of T tube has a single structure, limited function, long indwelling tube time and hospitalization period, and high medical expenses. The drainage of bile outside the T tube leads to water and electrolyte disorders, and the digestive and absorption function decreases, which affects the postoperative recovery of patients. Moreover, the drainage of the T tube is Negative pressure drainage can make intestinal juice frequently flow back into the biliary tract and pollute the bile
