Abstract
This utility model relates to medical material tech field, especially a kind of intravascular stent, comprise wire rack mount and macromolecule poly nitride layer, the surface of described wire rack mount is provided with macromolecule poly nitride layer, and the surface of described macromolecule poly nitride layer is provided with several projections.A kind of intravascular stent that this utility model provides, top layer adopts convex design, and the phenomenon effectively preventing post-surgical vascular support to offset lesion vessels occurs, and improves the success rate of operation, increases support biocompatibility simultaneously, promotes the endothelialization of stented vessel.
Description
Technical field
This utility model relates to medical material tech field, especially a kind of intravascular stent.
Background technology
Intravascular stent refers on the basis of tube chamber balloon expandable shaping; insert inner support in pathological changes section and support stenosis occlusion section blood vessel to reach; reduce blood vessel elasticity retraction and moulding again; keep the object that tube chamber blood flow is unobstructed; but inner support Post operation is being inserted to the lesion vessels of patient; often there will be intravascular stent skew lesion locations, do not reach the object of operation, thus cause the failure of operation.
Utility model content
The technical problems to be solved in the utility model is: in order to solve the convalescence after Miles operation intravascular stent skew lesion locations problem, this utility model provides a kind of intravascular stent, by arranging projection in macromolecule poly nitride layer, effectively solving convalescent period intravascular stent and easily offseting lesion vessels problem.
This utility model solves the technical scheme that its technical problem adopts: provide a kind of intravascular stent, comprise wire rack mount and macromolecule poly nitride layer, the surface of described wire rack mount is provided with macromolecule poly nitride layer, and the surface of described macromolecule poly nitride layer is provided with several projections.
Particularly, described macromolecule poly nitride layer is chitosan layer, gelatin layer or heparin layer.
Preferred version, described macromolecule poly nitride layer is chitosan layer, has sterilizing function, is conducive to the recovery of post-surgical vascular.
Particularly, described wire rack mount is titanium alloy support, cochrome support or stainless steel stent.
Preferred version, described projection is evenly distributed on described macromolecule poly nitride layer on the surface.
The beneficial effects of the utility model are: a kind of intravascular stent that this utility model provides, top layer adopts convex design, the phenomenon effectively preventing post-surgical vascular support to offset lesion vessels occurs, improve the success rate of operation, increase support biocompatibility simultaneously, promote the endothelialization of stented vessel, and there is the effect of bactericidal antiphlogistic, be conducive to the recovery of post-surgical vascular.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is further illustrated.
Fig. 1 is the structural representation of this utility model intravascular stent.
In figure: 1. wire rack mount; 2. macromolecule poly nitride layer; 3. protruding.
Detailed description of the invention
By reference to the accompanying drawings this utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with this utility model.
As shown in Figure 1, a kind of intravascular stent, comprises titanium alloy wires support 1, titanium alloy wires support 1 surface is coated with one deck chitosan layer, chitosan layer surface uniform is provided with the projection 3 of several ellipse arcs, and protruding 3 contact with blood vessel, increase the frictional force of blood vessel and intravascular stent.
Protruding 3 designs are adopted effectively to prevent the convalescence after Miles operation intravascular stent to offset lesion vessels, surface is coated with chitosan layer, makes this intravascular stent have the compatibility of good blood, promotes the endothelialization of stented vessel, and there is the effect of bactericidal antiphlogistic, be conducive to the recovery of blood vessel.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content in description, must determine its technical scope according to right.
