Furthermore, the terms "a", "an", and "the" mean two or more unless explicitly limited otherwise.

Referring to fig. 1-7, the present invention provides a technical solution:

be applied to anastomotic wicresoft's T type drainage tube of biliary tract, including T type pipe short arm 1 and integrated into one piece at T type pipe long arm 2 of T type pipe short arm 1 side, the end of T type pipe long arm 2 is taper pipe section 21, the head end of T type pipe long arm 2 is straight pipe section 22, the external diameter of taper pipe section 21 end position department is greater than the external diameter of taper pipe section 21 head end position department, the end of taper pipe section 21 is connected with T type pipe short arm 1, the external diameter of straight pipe section 22 is the same with the external diameter of taper pipe section 21 head end position department, puncture head 3 is installed to the head end of straight pipe section 22, puncture head 3 is including installing the end seat 31 of straight pipe section 22 head end position department and inlaying the pjncture needle 32 of establishing at end seat 31 head end, the terminal integrative bending type of pjncture needle 32 has curved needle 321. The head end of the T-shaped pipe long arm 2 extends into the bile duct after an incision is cut on the bile duct, at the moment, the needle head of the bent needle 321 faces and pierces the wall of the bile duct, so that the bent needle 321 can pierce the bile duct, then the puncture head 3 is pulled outwards, so that the puncture head 3 can drive the T-shaped pipe long arm 2 to be pulled out from the pierced wound, when the conical pipe section 21 is pulled out from the wound gradually, because the outer diameter of the conical pipe section 21 is gradually increased, the conical pipe section 21 can support the wound, the purpose of closing the wound is achieved, the pierced wound does not need to be sutured again, the operation is greatly simplified, the operation time is shortened, the biliary tract injury is lightened, and the biliary tract leakage risk is reduced.

In this embodiment, the short arm 1 and the long arm 2 of the T-shaped tube are both made of latex material, so that the T-shaped tube can be inserted without stimulating human body. The periphery of the tail end of the conical pipe section 21 is integrally formed with a plurality of convex anti-slip convex rings 211, when a puncture wound of the bile duct moves to the root of the conical pipe section 21 along the surface of the conical pipe section 21, the wound is clamped between the T-shaped pipe short arm 1 and the anti-slip convex rings 211, and the anti-slip convex rings 211 can prevent the conical pipe section 21 from sliding towards the bile duct at the wound due to the fact that the wound is tightened on the conical pipe section 21, and accordingly biliary leakage is prevented.

Specifically, the end seat 31 is a circular truncated cone-shaped structure, so that when the puncture needle 32 punctures and pulls out the bile duct, a punctured wound can slide to the straight tube section 22 along the outer surface of the end seat 31, stimulation on the bile duct is reduced, the tail end of the end seat 31 is integrally formed with the sleeve column 311, the sleeve column 311 extends into the straight tube section 22, and the periphery of the sleeve column 311 is integrally formed with the fixing protrusion 312 in an annular structure, so that under the action of the fixing protrusion 312, the straight tube section 22 tightly wraps the sleeve column 311, the puncture head 3 is prevented from falling off from the straight tube section 22, and meanwhile, because the T-shaped tube long arm 2 has elasticity, the puncture head 3 can be conveniently pulled out from the end of the straight tube section 22 after puncturing.

Furthermore, the angle of the included angle formed between the bent needle head 321 and the tail end of the puncture needle 32 is 30-45 degrees, so that the bent needle head 321 is in a tilting shape relative to the puncture needle 32, and the T-shaped tube long arm 2 and the puncture head 3 can conveniently extend into the bile duct and then puncture the bile duct by using the puncture head 3 from the interior of the bile duct.

In addition, the periphery of the puncture needle 32 is sleeved with a protective sleeve 4, the protective sleeve 4 is made of latex materials, a sleeve cavity 41 is formed in the protective sleeve 4, and the puncture needle 32 and the bent needle 321 extend into the sleeve cavity 41, so that the protective sleeve 4 protects the puncture needle 32 and prevents other people from being mistakenly injured by the T-shaped tube when the T-shaped tube is not used. The periphery of the head end of the protective sleeve 4 is integrally formed with a plurality of lugs 42, so that people can pull the protective sleeve 4 from the piercing head 3 by pulling the protective sleeve 4 from the lugs 42.

When the pierceable minimally-invasive T-shaped drainage tube applied to biliary tract anastomosis is used, firstly, after an incision is cut on a bile duct, the head end of a T-shaped tube long arm 2 extends into the bile duct, then a needle of a bent needle 321 faces and pierces the wall of the bile duct, so that the bent needle 321 can pierce the bile duct, and finally the piercing head 3 is pulled outwards, so that the piercing head 3 drives the T-shaped tube long arm 2 to be pulled outwards from a pierced wound, when the tapered tube 21 is pulled outwards from the wound, because the outer diameter of the tapered tube 21 is gradually increased, the tapered tube 21 supports the wound, the purpose of closing the wound is achieved, the pierced wound does not need to be sutured again, operation is greatly simplified, operation time is shortened, biliary tract injury is reduced, and risk of biliary tract leakage is reduced.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the description in the above embodiments and the description is only preferred examples of the present invention, and is not intended to limit the present invention, and that the present invention can have various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications all fall into the scope of the claimed invention. The scope of the invention is defined by the appended claims and equivalents thereof.
