Abstract
The utility model discloses a blood vessel medicine support comprising a columnar support body which comprises at least two annular unit members consisting of wave-shaped cylindrical rods. Adjacent annular unit members are connected into a tube network shaped structure by round connecting rods in the axial direction. The surfaces of the annular unit members and the round connecting rods are coated with medicine coatings. The support has good supporting performance, is not easy to deform and can prevent blood vessel blockage caused by re-narrowing of the blood vessel.
Description
Technical field
This utility model relates to a kind of therapeutic medical intravascular stent, is specifically related to a kind of pipe network shape blood vessel drug eluting stent.
Background technology
At present, treatment cardiovascular and peripheral blood vessel block pathological changes, and utilizing intravascular stent to carry out interventional therapy is effective means.Existing intravascular stent is because its unreasonable structure, and is yielding, thereby easily causes vascular restenosis and cause the obstruction again of blood vessel.
The utility model content
The technical problems to be solved in the utility model is at above-mentioned deficiency, and a kind of stressed good, on-deformable blood vessel drug eluting stent is provided.
In order to solve the problems of the technologies described above, this utility model provides a kind of blood vessel drug eluting stent of following structure, the stake body that comprises column, its construction features is: described stake body comprises at least two by being the annular element spare that wavy cylindrical bar constitutes, the adjacent annular unit piece connects into TRS by connecting round bar in the axial direction, scribbles medication coat on annular element spare and the surface that is connected round bar.
The blood vessel drug eluting stent of said structure, because its annular element spare constitutes by being wavy cylindrical bar, the adjacent annular unit piece is in the axial direction by connecting into pipe network structure along its circumferential staggered connection round bar, therefore stressed good, not yielding, can prevent the angiemphraxis that the restenosis because of blood vessel causes.
The length of described connection round bar is 0.02-0.08mm.
The length 5-50mm of described stake body, diameter are 1.5-7.5mm, and the diameter of cylindrical bar is 0.05-0.15mm.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail:
Fig. 1 is the projection structure sketch map that ends of the present utility model;
Fig. 2 is the axial expanded view of Fig. 1;
Fig. 3 is along the profile of A-A line among Fig. 2;
Fig. 4 is along the profile of B-B line among Fig. 2.
The specific embodiment
Blood vessel drug eluting stent as depicted in figs. 1 and 2, the stake body that comprises column, described stake body comprises at least two by being the annular element spare 1 that wavy cylindrical bar constitutes, adjacent annular unit piece 1 connects into TRS by connecting round bar 2 in the axial direction, and dotted portion is represented the back side of blood vessel drug eluting stent among Fig. 1.As shown in Figure 3 and Figure 4, scribble medication coat 3 on annular element spare 1 and the surface that is connected round bar 2.The length that connects round bar is 0.02-0.08mm, and the length of stake body is 5-50mm, and diameter is 1.5-7.5mm, and the diameter that has the cylindrical bar of medication coat is preferably 0.05-0.15mm.As shown in Figure 2, annular unit piece 1 is five in the present embodiment, and the trough that is positioned at top annular element spare 1 links together by being connected round bar 2 with the crest that is positioned at following annular element spare 1, and during connection, the arrangement that connects round bar 2 is as described below; Connection garden bar 2 on the same axial height a pair of crest at interval is connected with trough, has a pair of crest not to be connected with trough between promptly adjacent two connection round bars 2; Connection garden bar 2 on the different axial heights is staggered, and promptly the connection garden bar 2 of position infra is connected garden bar 2 with position adjacent not on same axis in last.
