Figure.
In figure：1 holder, 2 cylindrical sections, 3 umbrella sections, 4 ingress pipes, 5 hoses, 6 casings, 7 metal tubes, 8 fixing devices, 81 clampings
It covers, silk braid, 83 clamping screws, 9 screws, 10 handles in 82.
Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.
Referring to Fig.1-3, a kind of outer vascular anastomosis holder of liver and its transport system, including holder 1, ingress pipe 4, hose 5, set
One end of pipe 6, metal tube 7, fixing device 8, screw 9 and handle 10, handle 10 is equipped with metal tube 7, is equipped on metal tube 7
Fixing device 8 and screw 9, between handle 10 and fixing device 8, the one end of metal tube 7 far from handle 10 is connected with screw 9
Hose 5, the one end of hose 5 far from metal tube 7 are equipped with ingress pipe 4, and the outside of hose 5 is equipped with casing 6, pacifies on ingress pipe 4
Equipped with holder 1, holder 1 includes cylindrical section 2 and umbrella section 3, and the both ends of cylindrical section 2 are mounted on umbrella section 3, and holder 1 is by memory metal
It weaving, the surface of holder 1 is covered with polytetrafluoroethylene film, and the material of metal tube 7 is stainless steel, and the material of ingress pipe 4 is copper,
Ingress pipe 4 is fixedly connected with hose 5, and metal tube 7 is fixedly connected with hose 5, casing 6 and 5 pivot bush unit of hose, fixing device 8
Including retaining sleeve 81, interior silk braid 82 and clamping screw 83, retaining sleeve 81 is actively socketed on metal tube 7, the side of retaining sleeve 81
