Abstract
The utility model belongs to the coronary stent field of medical instruments, in particular to a micro-porous coronary stent which is composed of a plurality of main structural metal members and a plurality of connecting rods. The adjacent of the main structural metal members is connected by the connecting rods, which can form a circular closed support. The main structural metal members are regular snake-shaped rings that are formed by the connection of arc segments and snake-shaped segments. The connecting rods are connected with the wave tops of arch segments of the adjacent main structural metal members evenly and interspacely, and the snake-shaped segment is provided with a plurality of micro- porous. Given that the metal surface coverage ratio of the existing stent remains unchanged, the utility model increases the drug carrying capacity of the stent to prolong the function time of the drug; thereby the therapeutic effect can be effectively improved and the vascular restenosis ratio after the stent is transplanted can be reduced.
Description
Technical field
This utility model belongs to the coronary artery bracket field in the medical apparatus and instruments, particularly a kind of micropore ACS bracket.
Background technology
Coronary angioplasty is a kind of new treatment means for the treatment of cardiovascular disease in recent years in the percutaneous balloon cavity, and the coronary stent art is being used for the treatment of of growing up on this basis and prevents coronary stenosis and restenosis method the most efficiently and effectively.Common metal rack behind implant into body since the metal surface directly and blood vessel wall and blood thigmic stimulus the rejection function of human body to foreign body, cause tunica intima hamartoplasia and smooth muscle cell proliferation and form stent restenosis.In recent years, occurred preventing the medicine of mucosal hyperplasia, to reach the coronary artery bracket that prevents thrombosis and prevention of restenosis purpose in the support by coating on coronary artery bracket.But because the backbone metal surface coverage can not be too high, the medication amount that therefore is coated on rack surface is very limited, causes drug effect shorter in the time of tube wall, thereby can not reach ideal therapeutic effect.Therefore, the medicine amount of carrying that under the prerequisite that the metal surface coverage rate of existing support remains unchanged, improves support with prolong drug action time, to improve therapeutic effect be a problem that presses for solution.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of medicine amount of carrying that increases support under the situation that does not increase the metal surface coverage rate, the prolong drug micropore ACS bracket of action time is provided.
This utility model solves its technical problem and takes following technical scheme to realize:
This micropore ACS bracket, constitute by a plurality of metallic body member, connecting rod, the adjacent metal main component is by the connecting rod connection and form the barrel ring support, it is characterized in that: metallic body member is the regular serpentine rings that arc section links to each other and forms with snakelike section, the uniform interval of connecting rod is connected in the arc section wave crest place of adjacent metal main component, has a plurality of micropores on snakelike section.
And described micropore is a circular port, or square opening, or tri-angle-holed, or slotted eye, or slotted hole.
And described micropore is through hole or blind hole.
And described micropore has 1-10 on single snakelike section.
And described micropore is that linear is arranged, and perhaps non-linear is arranged.
Advantage of the present utility model and good effect are:
1. this micropore ACS bracket is formed by connecting by connecting rod by the snakelike ring-type metallic body member of a plurality of rules, owing to slightly be wider than arc section for snakelike section that constitutes metallic body member, can adopt the laser engraving method to carve out micro through-hole or blind hole at this snakelike section, and do not influence the mechanical property of timbering material after the perforate, when support compression or expansion deformation can not take place or be out of shape minimumly, therefore can not exert an influence to belongings in the micropore.
2. on support, carve out the micropore of a plurality of drug-carryings, be difficult in the micropore denuding because medicine is embedded in, thereby prolonged the pharmaceutically-active time, reduced the vascular restenosis rate after support is implanted by the blood erosion or by blood vessel wall.
3. this utility model overall structure is fairly simple, has improved the medicine amount of carrying of support at snakelike section of the metallic body member micropore by the engraving drug-carrying, has prolonged the time of drug effect in tube wall, thereby has improved therapeutic effect effectively.

The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described, but present embodiment is illustrative, rather than determinate.
This micropore ACS bracket, as shown in Figure 1, form by a plurality of metallic body member 1 and connecting rod 2, the adjacent metal main component is by the connecting rod connection and form the tunnel wall type support, metallic body member is the regular serpentine rings that arc section 3 links to each other and forms with snakelike section 4, the arc section wave crest of adjacent two metallic body member is relative, the uniform interval of connecting rod is connected in the arc section wave crest place of adjacent metal main component, adopt two uniform intervals of connecting rod to be connected between the adjacent serpentine rings in the present embodiment, in actual production, can increase or reduce the quantity of metallic body member and connecting rod according to actual needs, connecting rod is a straight rod type in the present embodiment, also can be other shape, as " n " shape, " V " shapes etc., present embodiment is not shown.
Adopt the laser engraving method to carve out micro through-hole or blind hole 5 at snakelike section, each snakelike section that constitutes the backbone metal main component in the present embodiment has three manholes, as shown in Figure 2, and being centered close on the straight line of manhole, and the center is equidistant.According to the length of snakelike section of hardware, the number of micropore can be 1-10.As shown in Figure 3, the circular port of engraving also can be the non-linear arrangement on snakelike section.Because snakelike section slightly be wider than arc section, do not influence the mechanical property of timbering material after the perforate, when support compression or expansion deformation can not take place or be out of shape minimumly, therefore can not exert an influence to belongings in the micropore.Certainly, micropore also can be carved on connecting rod, to increase drug loading.
As shown in Figure 4, the micropore of engraving can be circular port and also can be other shape on snakelike section, and as square opening 6, tri-angle-holed 7, slotted eye 8 or slotted hole 9, and micropore all can be through hole and also can be blind hole; And all can open 1-10 micropore according to the length of snakelike section of hardware; And the micropore on single snakelike section all can be linear array also can be the non-linear arrangement, and rectilinear micropore has been shown in the present embodiment, the micropore diagram that not shown non-linear is arranged.
Can be used for drug loading in the micropore in this micropore ACS bracket, can improve drug loading, with prolong drug action time; Also can load multiple different medicine to reach comprehensive effect, more can load radioactive source and carry out local radiotherapy in the body; Can also load microsensor or other small-sized treatment, diagnostor etc.Except in order to treatment or the angiocardiopathy preventing, the micropore support also with in order to transmit medicine to heart and other internal organs to reach topical therapeutic and prophylactic effect.
