Abstract
The invention discloses a vascular stent firm in supporting. The vascular stent is tubular and comprises a plurality of oval metal netted ring units which are distributed axially and connected through connectors. Each netted ring unit includes a plurality of netted rings connected closely. The vascular stent is wound with metal fixing rings outside, and the metal fixing rings are respectively arranged in the middle of each netted ring unit. The metal fixing rings which are wound outside the vascular stent and respectively arranged in the middle of each netted ring unit prevent the vascular stent from slipping off blood vessels and from deformation so as to improve firmness and support performance of the vascular stent greatly.
Description
Technical field
The intravascular stent that the present invention relates to a kind of firm supporting, belongs to manufacture technology field of medical appliance.
Background technology
Intravascular stent refers 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.Part inner support also has the effect of prevention of restenosis.Mainly be divided into coronary artery bracket, cerebrovascular support, renal artery stent, large artery trunks support etc.But existing intravascular stent is easily slippage in blood vessel, and fastness and supportive are poor.
Summary of the invention
For solving the deficiencies in the prior art, the object of the invention is to, a kind of intravascular stent of firm supporting is provided, fastness and supportive obviously improve.
Technical scheme of the present invention is: a kind of intravascular stent of firm supporting, described intravascular stent is tubulose, comprise the oval net ring element of a plurality of metals that distribute vertically, described net ring element is comprised of a plurality of close-connected net rings, between described each net ring element, by connector, connect, it is characterized in that, the external rings of described intravascular stent is wound with metal ring for fixing, and described ring for fixing is arranged on the middle part of each net ring element.
The intravascular stent of aforesaid a kind of firm supporting, is characterized in that, the ring for fixing of described each net ring element is two.
The intravascular stent of aforesaid a kind of firm supporting, is characterized in that, between described adjacent two ring for fixings, by horizontal stripe, connects.
The intravascular stent of aforesaid a kind of firm supporting, is characterized in that, between described adjacent two ring for fixings, by X-shaped connecting line, connects.
The intravascular stent of aforesaid a kind of firm supporting, is characterized in that, the connector between described each net ring element is linear or S shape.
The intravascular stent of aforesaid a kind of firm supporting, is characterized in that, the material of described intravascular stent is rustless steel, niti-shaped memorial alloy or cochrome.
The beneficial effect that the present invention reaches: the external rings of described intravascular stent is wound with metal ring for fixing, described ring for fixing is arranged on the middle part of each net ring element, prevent intravascular stent slippage in blood vessel, prevent intravascular stent distortion simultaneously, fastness and supportive are obviously improved.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described.Following examples are only for technical scheme of the present invention is more clearly described, and can not limit the scope of the invention with this.
As shown in Figure 1, a kind of intravascular stent of firm supporting, described intravascular stent is tubulose, comprise the oval net ring element of a plurality of metals that distribute vertically, described net ring element is comprised of a plurality of close-connected net rings 1, between described each net ring element, by connector 2, connect, the connector 2 between described each net ring element is linear, can be also S shape.
Preferably, the external rings of described intravascular stent is wound with two strip metal ring for fixings 3, and described ring for fixing 3 is arranged on the middle part of each net ring element.
Preferably, between described adjacent two ring for fixings 3, by X-shaped connecting line 4, connect, also can connect by horizontal stripe.
Preferably, the material of described intravascular stent is rustless steel, niti-shaped memorial alloy or cochrome.
The external rings of intravascular stent of the present invention is wound with metal ring for fixing 3, and described ring for fixing 3 is arranged on the middle part of each net ring element, prevents intravascular stent slippage in blood vessel, prevents intravascular stent distortion simultaneously, and fastness and supportive are obviously improved.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the technology of the present invention principle; can also make some improvement and distortion, these improvement and distortion also should be considered as protection scope of the present invention.
