A three-lumen T-tube

technical field

The utility model relates to the field of medical appliances, in particular to a three-chamber T-tube.

Background technique

Biliary exploration and T-tube drainage are currently the main surgical methods for the treatment of acute suppurative cholangitis and bile duct stones. These operations often leave necrotic and detached biliary epithelial tissue, residual biliary stones or blood clots and other biliary foreign bodies, aggregates formed by bacterial infection, etc. These substances are not drained smoothly and deposited in the intrahepatic bile duct, resulting in poor bile drainage. , which in turn lead to serious infections (Pseudomonas aeruginosa and fungi). In order to solve this problem, medical staff often use choledochoscope and other means to solve it after surgery, but there are still some limitations. Secondary acute infection. Therefore, how to effectively prevent and remove regenerated or residual stones in the postoperative biliary tract and avoid secondary biliary obstruction and infection has important clinical significance. Postoperative biliary irrigation through the T tube is a common way to solve the above problems, but premature irrigation can easily lead to biliary fistula, and excessive irrigation can cause abdominal distension and other gastrointestinal dysfunction.

Therefore, there is a need for a novel T-tube that can achieve flushing without causing problems such as biliary fistula and abdominal distension.

Utility model content

In order to solve the above problems, the utility model provides a three-cavity T-tube, including a long-arm tube and a short-arm tube, one end of the long-arm tube is connected to the side of the short-arm tube and the lumen is connected to form a T tube. Shaped tube, which also includes a first inner tube and a second inner tube, the body of the first inner tube and the second inner tube is located in the lumen of the T-shaped tube, the first inner tube and the second inner tube The front ends of the inner tube protrude from both ends of the short arm tube respectively, and the tube body at the front end of the first inner tube and the second inner tube is provided with a plurality of small holes, and the first inner tube and the second inner tube The tail ends of the tubes pass outwards from the tube walls of the long-arm tubes respectively.

Using the three-chamber T-tube of the utility model, the flushing liquid is introduced from the first inner tube, and the long-arm tube is used to drain the foreign matter through the T-tube, thereby avoiding the regeneration of stones. The second inner tube can be connected to negative pressure suction to attract the flushing fluid and prevent excessive flushing fluid from flowing into the intestine.

Further, the first inner tube and the second inner tube are respectively provided with a first guide wire and a second guide wire, which can guide the inner tube into the secondary and tertiary intrahepatic bile duct and the lower section of the common bile duct through cholangiography, and even pass through A second guide wire guides the second inner tube to the duodenum for enteral nutrition.

Further, the short-arm tube is arc-shaped away from the long-arm tube, which can reduce the patient's pain during extubation.

Further, the connecting position of the long arm tube and the short arm tube is in the middle of the body of the short arm tube.

Further, two rows of shackles parallel to the axial direction of the long arm tube are provided on the inner wall of the long arm tube, and the tube bodies of the first inner tube and the second inner tube respectively pass through the two rows of shackles .

detailed description

The principles and features of the present utility model are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the utility model, and are not used to limit the scope of the utility model.

As shown in FIG. 1 , a three-chamber T-tube of the present invention includes a long-arm tube 1 and a short-arm tube 2 , and the short-arm tube 2 is bent away from the long-arm tube 1 . One end of the long-arm tube 1 is connected to the middle side of the short-arm tube 2 and the lumen is communicated to form a T-shaped tube.

The inner wall of the long arm tube 1 is provided with two rows of shackles parallel to the axial direction of the long arm 1 tube, and the tube bodies of the first inner tube 3 and the second inner tube 4 respectively pass through the two rows of shackles, The front ends of the first inner tube 3 and the second inner tube 4 protrude from both ends of the short arm tube respectively, and the tube body at the front end is provided with a plurality of small holes. The first inner tube 3 and the second inner tube The tail end of the second inner tube 4 passes through the tube wall of the long-arm tube 1 respectively.

The first inner tube 3 and the second inner tube 4 are respectively provided with a first guide wire 5 and a second guide wire 6 for adjusting the positions of the front ends of the first inner tube 3 and the second inner tube 4 respectively .

During use, the short arm of the three-cavity T-tube of the present invention is properly trimmed and placed in the common bile duct. The corresponding end of the short arm 2 and the first inner tube 3 faces the top of the common bile duct. One end corresponding to the second inner tube 3 faces the lower part of the common bile duct, and the front ends of the first inner tube 3 and the second inner tube 4 are respectively guided to proper positions by the first guide wire 5 and the second guide wire 6 .
