Example one

As shown in fig. 1-3, the utility model provides a T-pipe for adjusting the supporting strength, which comprises a long pipe 5 and a short pipe 1, wherein the long pipe 5 and the short pipe 1 are communicated with each other, and one end of the long pipe 5 is connected with the pipe body of the short pipe 1; the section of the short conduit 1 is shaped into a circular arc; a T-shaped reinforcing pipe 2 is arranged in the T-shaped pipe in a matched and penetrating mode, and the T-shaped reinforcing pipe 2 is fixed on the inner wall of the T-shaped pipe; two short arms 22 of the reinforcing pipe 2 extend into the short guide pipe 1 and are closed; the long arm 21 of the reinforcing pipe 2 extends into the long guide pipe 5 and is connected with the guide pipe 4; the guide pipe 4 is fixed on the inner wall of the long guide pipe 5, extends along the length direction of the long guide pipe 5 and penetrates out; the long guide pipe 5, the short guide pipe 1 and the reinforcing pipe 2 are made of flexible materials.

The long duct 5 is usually a circular duct. The reinforcing pipe 2 is fixed on the inner wall of the T pipe; the reinforcing pipe 2 is fixedly communicated with a long arm 21 through two short arms 22 to form a T shape. The reinforcing pipe 2 can be separated from the T pipe and is bonded and glued on the inner wall of the T pipe; it may be formed integrally with the long duct 5 and the short duct 1 of the T-pipe by injection molding. The feed-through tubes 3 are usually fixed against the inner walls of the long and short ducts 1, 5, which are likewise made of a flexible material. The outer edge of each assembly is polished and trimmed to be in smooth transition, sharp corners and other rapidly changed shapes are avoided, and the common bile duct is prevented from being scratched. The flexible material is usually made of resin materials such as high polymer, rubber, etc., wherein medical rubber is most commonly used. As a medical rubber product, except that the physical properties meet the requirements, the rubber product has to ensure no toxicity and chemical inertness, and particularly, the rubber product in vivo has the characteristics of no pathogenicity, no damage to adjacent tissues, no allergy, good aging performance and the like.

The long duct 5 is connected to the middle of the short duct 1, dividing the short duct 1 into two symmetrical sections. The long duct 5 is preferably arranged perpendicular to the short duct 1.

The two reinforcing pipes 2 are symmetrically arranged relative to the central axis of the long guide pipe 5 and are communicated with each other through the communicating pipe 3.

Set up two reinforcing pipes 2, can improve the support intensity of T pipe by great degree. In addition, after two reinforcing pipes 2 are arranged, correspondingly, the injection amount of the filler is increased greatly, and the injection amount is adjusted in a large range, so that the variation range of the support strength of the T pipe is large, the adaptability is high, and the practicability is high.

The section of the short conduit 1 is semicircular, and the short conduit 1 can be folded in half from the connection part of the long conduit 5 and the short conduit 1 to form a circular pipeline.

The section of the reinforcing pipe 2 is cylindrical or oblate, and the outer wall of the reinforcing pipe is fixedly attached to the inner walls of the long guide pipe 5 and the short guide pipe 1.

The closed end of the reinforcing tube 2 is located inside the short duct 1. That is to say, the length of the two short lengths of pipe 1 is greater than the short arms 22 of the reinforcing tube 2. The closed end of the short arm 22 is retracted into the short tube 1. So as to suitably tailor the length of the short catheter 1 according to the intraoperative situation.

The T pipe for adjusting the supporting strength plays a role of reinforcing the short guide pipe 1 and the long guide pipe 5 after filling media are introduced into the reinforcing pipe 2. A certain amount of air, clean water and normal saline can be led into the reinforcing pipe 2 from the guide pipe 4, and then the reinforcing pipe is closed, so that the strength and the rigidity of the T pipe can be effectively improved. Air, clear water and normal saline are continuously introduced or discharged, so that the supporting strength and the supporting force of the T-shaped pipe can be changed. In addition, after filling media are injected into the reinforcing pipe 2, the T pipe has stronger supporting force and can be implanted into the liner main pipe to prevent the liner main pipe from accidentally slipping; after the filling medium is discharged, the supporting force of the T tube is reduced, and the T tube can be smoothly pulled out from the common bile duct without damaging the common bile duct. The T tube with adjustable supporting strength can effectively reduce medical injury caused by the application of the T tube in an operation.

The guide tube 4 protrudes through the wall of the long guide tube 5. Of course, the guiding tube 4 can also directly extend out through the orifice of the long guiding tube 5 along the length direction of the long guiding tube 5. The guide pipe 4 extends outwards to conveniently inject or discharge air and clean water into the reinforcing pipe 2, so that drainage is facilitated.

The end of the overhanging section of the guide tube 4 is connected with a valve body 7. The valve body 7 plays a role in opening and closing, and after air and clean water are injected into the guide pipe 4, the valve body 7 is closed to seal the guide pipe 4. The guide pipe 4 has certain strength and rigidity under the filling support of air and clean water, and can strengthen the T-shaped pipe. When the filling medium needs to be discharged, the valve is only required to be opened lightly for direct discharge and drainage, and the operation is simple and convenient.

The extending section of the guide tube 4 is communicated with a bag body 6. More filling media can be stored in the capsule body 6, so that the filling media can be filled to a certain extent, and after the T-shaped tube is implanted into the common bile duct, the T-shaped tube can be pulled to play a role in buffering, so that the reinforcing tube 2 can be kept to be strongly supported. The balloon 6 is in a transparent state, and whether the injection amount of the filling medium is proper or not can be accurately judged by observing the expansion degree of the balloon 6. Preventing the reinforcing tube 2 from being excessively expanded and from being broken due to excessive pressure.

The outer wall of the T pipe is marked with contour lines corresponding to the shape, the size and the position of the inner reinforcing pipe 2. The T-tube is cut appropriately during use to prevent damage to the T-shaped reinforcement tube 2 during cutting.

Example two

The long duct 5 is usually a circular duct. The reinforcing pipe 2 is fixed on the inner wall of the T pipe; the reinforcing pipe 2 is fixedly communicated with a long arm 21 through two short arms 22 to form a T shape. The reinforcing pipe 2 can be separated from the T pipe and is bonded and glued on the inner wall of the T pipe; it may be formed integrally with the long duct 5 and the short duct 1 of the T-pipe by injection molding. The feed-through tubes 3 are usually fixed against the inner walls of the long and short ducts 1, 5, which are likewise made of a flexible material. The outer edge of each assembly is polished and trimmed to be in smooth transition, sharp corners and other rapidly changed shapes are avoided, and the common bile duct is prevented from being scratched. The flexible material described above is generally medical rubber. As a medical rubber product, except that the physical properties meet the requirements, the rubber product has to ensure no toxicity and chemical inertness, and particularly, the rubber product in vivo has the characteristics of no pathogenicity, no damage to adjacent tissues, no allergy, good aging performance and the like.

A notch 8 is formed in one side, opposite to the joint of the long catheter 5 and the short catheter 1, of the short catheter 1, and the position of the notch 8 corresponds to that of the long catheter 5. The notch 8 is semicircular, U-shaped or V-shaped. The notch 8 is arranged, so that the phenomenon that the catheter walls are overlapped and crossed at the notch 8 when the two short catheters 1 are overlapped can be avoided, the outer diameter of the notch can be increased due to the overlapping and crossing, and the common bile duct can be scratched when the T-shaped catheter is pulled out.

The section of the short conduit 1 is semicircular, and the short conduit can be folded from the notch 8 to form a circular pipeline.
