Abstract
The utility model discloses a sectional intravascular stent which comprises an artificial vessel layer and net stents arranged in the artificial vessel layer. The net stents are divided into a first stent, a second stent and a third stent. The first stent and the second stent are arranged on two sides of the artificial vessel layer, and the third stent is arranged between the first stent and the second stent. The stent adopts a sectional stent structure, reduces damage of a vessel to normal activity, ensures that the intravascular stent can support the narrow position of the vessel, reduces contact area between the stents and the vessel and reduces vessel abrasion.
Description
Technical field
This utility model relates to field of medical products, particularly relates to a kind of stagewise intravascular stent.
Background technology
Intravascular stent refers to narrow, the inaccessible blood vessel for support human body endogenous cause of ill pathological changes, recovers the tubular device of blood circulation.Intravascular stent conventionally adopts metal or macromolecular material etc. to have some strength and flexible materials processing is made, and can stay in human vas for a long time or temporarily.Intravascular stent is on the basis being shaped at tube chamber balloon expandable, inserts inner support support stenosis occlusion section blood vessel to reach in pathological changes section, reduces blood vessel elasticity retraction and moulding again, keeps the unobstructed object of tube chamber blood flow.
Conventional intravascular stent has a defect after long-time use, in the tremulous pulse at some movable joint places, inserts intravascular stent, easily makes intravascular stent flexural deformation, simultaneously easy injured blood vessel tube wall.
Utility model content
The technical problem that this utility model mainly solves is to provide a kind of stagewise intravascular stent; adopt the supporting structure of stagewise; can reduce damaging that blood vessel produces normal activity; in the time ensureing that intravascular stent can strut in angiostenosis place; can reduce again contact area between support and blood vessel, reduce blood vessel wearing and tearing.
For solving the problems of the technologies described above, the technical scheme that this utility model adopts is: a kind of stagewise intravascular stent is provided, comprise: artificial blood vessel layer and network, described network is located at artificial blood vessel layer inside, described network is divided into the first support, the second support and the 3rd support, described the first support and the second support are located at respectively the both sides of artificial blood vessel layer, are provided with the 3rd support between described the first support and the second support.
In preferred embodiment of this utility model, the pipe thickness of described artificial blood vessel layer is 0.08-0.10mm.
In preferred embodiment of this utility model, described the 3rd support is connected with the second support with the first support respectively.
In preferred embodiment of this utility model, described network is made up of Nitinol or medical stainless steel material.
The beneficial effects of the utility model are: the supporting structure that adopts stagewise; can reduce damaging that blood vessel produces normal activity; in the time ensureing that intravascular stent can strut in angiostenosis place, can reduce again contact area between support and blood vessel, reduce blood vessel wearing and tearing.
Brief description of the drawings
In order to be illustrated more clearly in the technical scheme in this utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing, wherein:
Fig. 1 is the structural representation of a kind of stagewise intravascular stent one preferred embodiment of the present utility model;
In accompanying drawing, the labelling of each parts is as follows: 1, artificial blood vessel layer, 2, the first support, 3, the second support, 4, the 3rd support.
Detailed description of the invention
To the technical scheme in this utility model embodiment be clearly and completely described below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not making all other embodiment that obtain under creative work prerequisite, all belong to the scope of this utility model protection.
This utility model embodiment comprises:
A kind of stagewise intravascular stent, comprise: artificial blood vessel layer 1 and network, described network is located at artificial blood vessel layer 1 inside, described network is divided into the first support 2, the second support 3 and the 3rd support 4, described the first support 2 and the second support 3 are located at respectively the both sides of artificial blood vessel layer 1, between described the first support 2 and the second support 3, be provided with the 3rd support 4, described the 3rd support 4 is connected with the second support 3 with the first support 2 respectively, by stagewise network, while work in intravascular stent is located at human vas, slowly strut, to reach the effect of recovering blood circulation, the area that network is contacted with blood vessel wall reduces, can reduce human normal motion time, intravascular stent is to arterial vascular damage, make people in life at ordinary times, can specially not notice that tremulous pulse inside is provided with medical supplies, improve safety, also be not easy to make patient to produce flurried emotion.
In addition, the pipe thickness of described artificial blood vessel layer is 0.08-0.10mm, and less thickness can further reduce artificial blood vessel layer to arterial vascular damage.
In addition, described network is made up of Nitinol or medical stainless steel material.
The beneficial effect of a kind of stagewise intravascular stent of this utility model is:
The supporting structure that adopts stagewise, can reduce damaging that blood vessel produces normal activity, in the time ensureing that intravascular stent can strut in angiostenosis place, can reduce again contact area between support and blood vessel, reduces blood vessel wearing and tearing.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes this utility model description to do; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
