Embodiment Construction

[0016] In order to easily understand the technical means, creative features, goals and effects of the present invention, the present invention will be further described below in conjunction with specific illustrations.

[0017] Such as figure 1 Shown, a kind of blood vessel expansion stent, it is made of net tube 1 and support member 2, and support member 2 is arranged on one end of net tube 1, and net tube 1 is made of interconnected vena cava net tube 11, iliac vein net tube 12, One end of the vena cava cylinder 11 is provided with a support member 2, and the other end is connected to the iliac vein cylinder 12. The outer diameter of the vena cava cylinder 11 is 0.1-8mm larger than the inner diameter of the vena cava 3, and the outer diameter of the iliac vein cylinder 12 is larger than that of the iliac vein 4. The inner diameter is 0.1-8mm larger, and the vena cava mesh cylinder 11 and the iliac vein mesh cylinder 12 are respectively placed in the vena cava 3 and the iliac...

Abstract

The invention discloses a blood vessel dilation stent, and belongs to the technical field of blood vessel dilation stents. The blood vessel dilation stent is composed of a mesh cylinder and a supporting part, wherein the mesh cylinder is composed of a vena cava mesh cylinder and an iliac vein mesh cylinder which are mutually connected, the supporting part is arranged at one end of the vena cava mesh cylinder, the other end of the vena cava mesh cylinder is connected with the iliac vein mesh cylinder, the outer diameter of the vena cava mesh cylinder is larger than the inner diameter of vena cava by 0.1-8 mm, the outer diameter of the iliac vein mesh cylinder is larger than the inner diameter of each iliac vein by 0.1-8 mm, the vena cava mesh cylinder and the iliac vein mesh cylinder are placed in the vena cava and the iliac vein on one side respectively, a blood opening is formed in the joint of the vena cava mesh cylinder and the iliac vein mesh cylinder, and the blood opening communicates with the iliac vein on the other side. The mesh cylinder is composed of the vena cava mesh cylinder and the iliac vein mesh cylinder which are mutually connected, and due to the fact that the vena cava is not liable to move, the vena cava mesh cylinder and the supporting part are placed in the vena cava for fixation so that displacement, caused by human motion, of the blood vessel stent canbe prevented, effects of the blood vessel stent can be maintained for a long time, and the service life of the blood vessel stent is prolonged.

Description

technical field [0001] The invention relates to a blood vessel expansion stent, which belongs to the technical field of blood vessel expansion stents. Background technique [0002] Iliac vein compression syndrome (also known as May-Thurner syndrome or Cockett syndrome) is a syndrome caused by the venous return disorder of the lower extremities caused by iliac vein compression, which can lead to lower extremity venous hypertension, and then lead to lower extremity venous valve insufficiency, shallow Varicose veins, and may be secondary to the formation of iliac-femoral vein thrombosis. It is now considered that Cockett syndrome is a very important cause of deep venous valve insufficiency, thrombosis and superficial varicose veins of the lower extremities. If Cockett syndrome can be diagnosed and treated effectively in the early clinical stage, the occurrence of thrombosis will be avoided or reduced. [0003] At present, open surgery is rarely carried out, and most of them ar...
