Description
Technical field
This utility model relates to one and is mainly used in repairing arterial vascular arterial intracavitary stent artificial blood vessel, belongs to the medical device of human implantable.
Background technology
At present, in the treatment of arterial disease, especially for the pathological changes such as aneurysm, artery dissection, in normal employing lumen of artery, interventional method is treated, send into arterial disease position by arterial intracavitary stent artificial blood vessel, in lumen of artery, rebuild arterial wall by artificial blood vessel, recover normal blood flow.Along with the application extension to arterial intracavitary stent artificial blood vessel, start in operation on aorta, adopt branching type arterial intracavitary stent artificial blood vessel to carry out the reparation of aortic arch pathological changes.The branching type arterial intracavitary stent artificial blood vessel applied in operation is at present overall structure, when the quantity of bifurcated artery generation pathological changes, position and size are different, integrated support is not easy to adjust according to the state of an illness, does not likely mate due to size and develops complications.Meanwhile, there is the risk of over-treatment in integrated support artificial blood vessel.
In order to improve the suitability of branching type stent-graft, need to adjust the level of branching type stent-graft in each branch, to meet instructions for use better.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of arterial intracavitary stent artificial blood vessel rational in infrastructure, allow to adjust branch stent artificial blood vessel according to the quantity of patient's bifurcated artery pathological changes, position and size difference in operation, with the range of application of expanded stent artificial blood vessel, reduce Operative risk.
Arterial intracavitary stent artificial blood vessel designed by this utility model is combined by stent-graft and artificial blood vessel's connector, and stent-graft is divided into independently preformed hole stent-graft and independently wide edge stent-graft.
In this utility model, the diameter of preformed hole stent-graft is between 22mm-42mm, and length is between 80mm-220mm, and preformed hole is rectangle, and its length is between 10mm-70mm, and its width is between 15-35mm.
In this utility model, the spacing of preformed hole at artificial blood vessel's long axis direction one lateral edges distance homonymy artificial blood vessel edge is between 1mm-40mm.
In this utility model, the diameter of wide edge stent-graft is between 10mm-26mm, length is between 10mm-40mm, and the edge of artificial blood vessel side is mutually vertical with artificial blood vessel's major axis to artificial blood vessel's lateral, and the width at this edge is between 5mm-25mm.
In this utility model, support is formed artificial blood vessel and supports also and the mutual consolidation of artificial blood vessel, and consolidation style can be continuous consolidation, also can be to be interrupted consolidation.
In this utility model, artificial blood vessel's connector length is between 12mm-80mm, and width is between 18mm-40mm, and have 2 or 3 holes along connector major axis, the diameter in hole is between 12-28, and the spacing in hole is between 5mm-15mm.
This utility model is when applying, identical with the application of the branching type arterial intracavitary stent artificial blood vessel applied at present, is also, by support release, arterial intracavitary stent artificial blood vessel is sent into lesion region.Different, according to the concrete condition of each bifurcated artery pathological changes, can determine whether insert wide edge stent-graft, if need to insert, select suitable size, if without the need to inserting, keep primordial condition, avoiding over-treatment.When needs insert 2 or 3 wide edge stent-grafts, insert bifurcated artery again after wide edge stent-graft is inserted in artificial blood vessel's connector in position, strengthen the repairing effect to aortic arch between bifurcated artery thus.After completing the reparation to bifurcated artery, insert preformed hole stent-graft, keep preformed hole towards bifurcated artery, guarantee that the blood flow of preformed hole stent-graft intracavity can flow into bifurcated artery.
The advantage of the arterial intracavitary stent artificial blood vessel designed by this utility model is:
1., according to the pathological changes situation of bifurcated artery, select the quantity of Stent Implantation artificial blood vessel, position and size independently;
2. strengthen the reparation integrity between bifurcated artery by artificial blood vessel's connector;
3. independently insert preformed hole stent-graft, not by the impact of branch stent, guarantee to repair fully reliable.
Arterial intracavitary stent artificial blood vessel designed by this utility model is applicable to the treatment of aortic arch pathological changes, such as, for the treatment of aorta A type interlayer.

Detailed description of the invention
In conjunction with specific embodiments the structure of arterial intracavitary stent artificial blood vessel designed by this utility model and embodiment are described further with reference to the accompanying drawings below.
Preformed hole stent-graft as shown in Figure 1, artificial blood vessel 1-1 diameter is 32mm, length is 180mm, preformed hole 1-3 length is 60mm, width is 22mm, preformed hole is 20mm in the spacing at artificial blood vessel's long axis direction one lateral edges distance homonymy artificial blood vessel edge, and support 1-2 and artificial blood vessel 1-1 is for be interrupted consolidation; Wide edge artificial blood vessel as shown in Figure 2, the diameter of artificial blood vessel 2-1 is 16mm, and length is 26mm, and border width is 8mm, and support 2-2 and artificial blood vessel 2-1 is for be interrupted consolidation; Artificial blood vessel's connector as shown in Figure 3, artificial blood vessel 3-1 length is 63mm, and width is 25mm, and the quantity of hole 3-2 is 3, and the diameter in hole is 17mm, and the spacing in hole is 8mm; The assembling of arterial intracavitary stent artificial blood vessel as shown in Figure 4, wide edge stent-graft 4-1 totally 3, be inserted in 3 holes of artificial blood vessel's connector 4-2 respectively, between wide edge stent-graft 4-1 and artificial blood vessel's connector 4-2, form complete connection, and formed involutory with the preformed hole of preformed hole stent-graft 4-3.
This utility model, by adjusting the quantity of wide edge stent-graft, position and size, meets the requirement for the treatment of, the range of application of expanded stent artificial blood vessel, reduces the risk of stent in the treatment.
