Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
Referring to fig. 1-3, an extrahepatic vascular anastomosis stent and a conveying system thereof comprises a stent 1, an ingress pipe 4, a hose 5, a sleeve 6, a metal pipe 7, a fixing device 8, a screw 9 and a handle 10, wherein one end of the handle 10 is provided with the metal pipe 7, the metal pipe 7 is provided with the fixing device 8 and the screw 9, the screw 9 is positioned between the handle 10 and the fixing device 8, one end of the metal pipe 7, which is far away from the handle 10, is connected with the hose 5, one end of the hose 5, which is far away from the metal pipe 7, is provided with the ingress pipe 4, the sleeve 6 is arranged outside the hose 5, the ingress pipe 4 is provided with the stent 1, the stent 1 comprises a cylindrical section 2 and an umbrella section 3, the umbrella sections 3 are arranged at two ends of the cylindrical section 2, the stent 1 is woven by memory metal, the surface of the stent 1 is coated with a polytetrafluoroethylene film, the metal pipe 7 is made of stainless steel, the ingress pipe 4, the metal pipe 7 is fixedly connected with the hose 5, the sleeve 6 is movably sleeved with the hose 5, the fixing device 8 comprises a clamping sleeve 81, an inner thread sleeve 82 and a locking bolt 83, the clamping sleeve 81 is movably sleeved on the metal pipe 7, the side edge of the clamping sleeve 81 is communicated with the inner thread sleeve 82, and the locking bolt 83 is sleeved in the inner thread sleeve 82 through threads.
