Abstract
The invention discloses a drug-loading vascular stent. The drug-loading 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 which are connected closely. A drug-loading tube sleeves the vascular stent, and a plurality of drug release pores are uniformly distributed in the surface of the drug-loading tube. Drug-loading rate can be increased through the drug-loading tube which sleeves the vascular stent. The drug release pores distributed in the surface of the drug-loading tube uniformly facilitate quick and uniform release of drug to improve treatment effect.
Description
Technical field
The present invention relates to a kind of medicine carrying intravascular stent, belong to technical field of medical instruments.
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.Medicine carrying on intravascular stent, can treat vascular restenosis in the mode of topical, so produced coating stent of medicine.But the drug release rate of medication coat is uncontrollable, and drug loading is limited, and therapeutic effect is not obvious.
Summary of the invention
For solving the deficiencies in the prior art, the object of the invention is to, a kind of medicine carrying intravascular stent is provided, drug loading is large, and medicine is easy to discharge.
Technical scheme of the present invention is: a kind of medicine carrying intravascular stent, described intravascular stent is tubulose, comprise the oval net ring element of the multiple metals that distribute vertically, described net ring element is made up of multiple close-connected net rings, between described each net ring element, connect by connector, it is characterized in that, the outer cover of described intravascular stent is provided with medicine carrying pipe, and described medicine carrying tube-surface is evenly distributed with multiple drug release micropores.
Aforesaid a kind of medicine carrying intravascular stent, is characterized in that, described medicine carrying pipe is bimetallic tube, between two-layer pipe, forms medicine storage cavity.
Aforesaid a kind of medicine carrying intravascular stent, is characterized in that, described connector is X-shaped, and described connector is evenly arranged at intervals between described net ring element.
Aforesaid a kind of medicine carrying intravascular stent, is characterized in that, the ratio of the long and short diameter of described oval net ring element is 3:2.
Aforesaid a kind of medicine carrying intravascular stent, is characterized in that, the length of described intravascular stent is 2-30cm.
Aforesaid a kind of medicine carrying intravascular stent, 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: be provided with medicine carrying pipe in the outer cover of intravascular stent, can improve drug loading, and be evenly distributed with multiple drug release micropores at medicine carrying tube-surface, favourablely discharge fast and uniformly with medicine, improved therapeutic effect.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
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 medicine carrying intravascular stent, described intravascular stent is tubulose, comprise the oval net ring element of the multiple metals that distribute vertically, described net ring element is made up of multiple close-connected net rings 1, between described each net ring element, connect by connector 2, described connector 2 is X-shaped, and described connector 2 is evenly arranged at intervals between described net ring element.The outer cover of described intravascular stent is provided with medicine carrying pipe 3, and described medicine carrying pipe 3 surface uniforms are distributed with multiple drug release micropores 4.
Preferably, described medicine carrying pipe 3 is bimetallic tube, forms medicine storage cavity 5 between two-layer pipe.
Preferably, the ratio of the long and short diameter of described oval net ring element is 3:2.
Preferably, the length of described intravascular stent is 2-30cm.
Preferably, the material of described intravascular stent is rustless steel, niti-shaped memorial alloy or cochrome.
The present invention is provided with medicine carrying pipe 3 in the outer cover of intravascular stent, can improve drug loading, and is evenly distributed with multiple drug release micropores 4 at medicine carrying tube-surface, favourablely discharges fast and uniformly with medicine, has improved therapeutic effect.
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.
