Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in further detail.
A kind of iliac artery catheter kit as shown in Fig. 1 ~ 3, comprises conduit and seal wire.Main body 11 head end of described conduit is that circular arc bends, and bending section 12 upper surface of conduit is provided with superslide layer 12a, and the width of superslide layer is 1cm.Axis angle α between the arc free arm 121 of described bending section and catheter main body is 45 ~ 60 °, and the end of arc free arm is the pyramidal structure that upper end diameter is large, lower end diameter is little.The tube wall of described conduit comprises skin 101, middle level 102 and internal layer 103; The tube wall internal layer of conduit is hydrophilic layer, and middle level is the woven mesh structure of stainless steel silk, and skin is polyethylene layer, and outer field outer side surface is smooth; In said structure, outer to make for polythene material, its character determines shape and the hardness of conduit, smooth outer surface can prevent blood vessel internal membrane damage and thrombosis: middle level is the woven mesh structure of stainless steel silk, for the skeleton of guiding catheter, make conduit not easily collapse-deformation and have anti-fracture to act on and control power will be turned round conduct to catheter tip: internal layer is that polytetrafluoroethylmaterial material is made, politef is hydrophilic polymer, lubricate, the frictional force of equipment and guiding catheter inner chamber is got involved after reducing, and antithrombotic.
