Description
Technical field
The utility model relates to a kind of blood vessel dilatation brackets, belong to blood vessel dilatation support technology field.
Background technique
Iliac Vein Compression Syndrome (also known as May-Thurner syndrome or Cockett syndrome), is that iliac vein compression is drawn
Rise veins of lower extremity reflux obstacle and there is syndrome, can lead to veins of lower extremity high pressure, then lead to vein valve function in lower limbs not
Entirely, varicose vein, and can secondary iliac-femoral venous thrombus formation.Think that Cockett syndrome is deep veins of lower limb
The critically important reason of valvular inadequacy and thrombosis and varicose vein, as can in Cockett syndrome clinical early stage
Diagnosis and effectively treatment are made, the generation of thrombosis will be avoided or reduced.
Open surgery is carried out less at present, is mostly interventional therapy substitution.Interventional therapy is expanded using iliac vein lesion, is interior
Set stenting, long-term Clinical Follow-up confirm iliac vein stent-assisted angioplasty have the characteristics that safely, effectively, long-term patency rate it is high,
It is the effective means for treating iliac vein compression syndrome.It is less for the special stand of iliac vein compressing syndrome exploitation at present,
Good filter should have following characteristics: (1) accurate positioning, be easy release；(2) good biocompatibility；(3) enough bearings
Power；(4) it maintains iliac vein open and does not allow to be also easy to produce thrombus；(5) restore bone venous blood flow state and increase blood flow.
Currently, iliac vein intravascular stent is made of net cylinder and supporting element, in net cylinder one end, intravascular stent is logical for supporting element setting
It crosses supporting element to fix with blood vessel, is propped up blood vessel by net cylinder, restore blood flow state.Iliac vein intravascular stent product clinically
In the presence of hypodynamic problem is supported, iliac vein can be moved with human motion, and intravascular stent is easy to happen displacement in iliac vein,
Lead to the ineffective effect of intravascular stent.And vena cave is not easily shifted, can be used in fixed intravascular stent, improves fixed structure
Stability.Therefore a kind of blood vessel dilatation bracket is designed, it there are enough support forces to guarantee to restore iliac vein blood status.
Summary of the invention
Technical problem to be solved by the utility model is to provide a kind of blood vessel dilatation brackets, it solves current ilium
Vein blood vessel bracket, which exists, supports hypodynamic problem.
Technical problem to be solved in the utility model takes following technical scheme to realize:
A kind of blood vessel dilatation bracket, it is made of net cylinder and supporting element, supporting element setting in net cylinder one end, the net cylinder by
Vena cave net cylinder interconnected, iliac vein net cylinder are constituted, and vena cave net cylinder one end is equipped with supporting element, the other end and iliac vein net
Cylinder connection, vena cave net cylinder outer diameter is 0.1-8mm bigger than vena cave internal diameter, and iliac vein net cylinder outer diameter is 0.1- bigger than iliac vein internal diameter
Vena cave net cylinder, iliac vein net cylinder are placed in vena cave, in the iliac vein of side respectively, vena cave net cylinder, iliac vein net by 8mm
Cylinder junction is open equipped with blood, and blood opening is connected to the iliac vein of the other side.
As preferred embodiment, the vena cave net cylinder, iliac vein net cylinder, supporting element are integrally cut by laser by niti material
Or it works out.
As preferred embodiment, the vena cave net cylinder, iliac vein net cylinder junction are equipped with development point.
As preferred embodiment, net cylinder both ends port is respectively equipped with development point.
As preferred embodiment, the blood opening is equipped with development point.
As preferred embodiment, the supporting element surrounds circumference by 6-12 zigzag wave band, which compares vena cave
The big 1-2mm of net cylinder outer diameter.
The beneficial effects of the utility model are: net cylinder is made of vena cave net cylinder interconnected, iliac vein net cylinder, due to
Vena cave is not easily shifted, therefore vena cave net cylinder and supporting element are placed in vena cave and fixed, and can prevent from transporting due to human body
The displacement of intravascular stent caused by dynamic, can maintain the function and effect of intravascular stent for a long time, and extend intravascular stent uses the longevity
Life；Vena cave net cylinder, iliac vein net cylinder junction are open equipped with blood, do not influence the blood flow of other side iliac vein.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure: net cylinder 1, vena cave net cylinder 11, iliac vein net cylinder 12, blood opening 13, supporting element 2, vena cave 3, ilium is quiet
Arteries and veins 4, development point 5.
Specific embodiment
In order to which the technical means, creative features, achievable purpose and effectiveness to the utility model are easy to understand, tie below
Conjunction is specifically illustrating, and the utility model is further described.
As shown in Figure 1, a kind of blood vessel dilatation bracket, it is made of net cylinder 1 and supporting element 2, and supporting element 2 is arranged in net cylinder 1
One end, net cylinder 1 are made of vena cave net cylinder 11 interconnected, iliac vein net cylinder 12, and 11 one end of vena cave net cylinder is equipped with support
