Abstract
The invention relates to a double-top ring coronary artery frame, a pipe wall ring frame is formed by metal main body units which are connected with each other, the metal main body unit is formed by a large snake-shaped ring segment, a double-top snake-shaped ring segment and a small snake-shaped ring segment which are connected with each other in turn, the neighboring large snake-shaped ring segment and the small snake-shaped ring segment of the metal main body units are connected with each other by single top rings, the front metal main body unit is connected with the rear metal main body unit through the double-top snake-shaped ring segment by using a connecting rod and the single top ring formed by the large snake-shaped ring segment and the small snake-shaped ring segment. The metal main body unit of the double-top ring coronary artery frame is composed of the large snake-shaped ring segment, the double-top snake-shaped ring segment and the small snake-shaped ring segment at interval, the connecting rod adopts structure characteristic mode of a straight rod or a n-shaped connecting rod, the flexibility of the frame can be effectively increased, the frame has small retracting performance in order that after the frame is expanded at last, the diameter of the frame can be accurately suitable for the blood vessel diameter on pathological change, the coronary artery frame of the invention has high scientificaalness.
Description
Technical field
The present invention relates to the coronary artery bracket in medical material field, especially a kind of double top-cover coronary bracket.
Background technology
The coronary stent art is that interventional therapy method is hindered by a kind of novel Wicresoft, and self-application development since clinical is very fast, uses more and more widely.Multiple support is arranged at present clinically, though emphasis has nothing in common with each other, its purpose all is raising support force, pliability and the spreading performance that improves support etc.But the design of existing support often can not reach above index simultaneously, the following defective of ubiquity: the 1. pair relatively large support of metal coverage rate, though its radial support power is improved, the pliability of support is relative with transportation performance less, is unfavorable for that zigzag vascular system treats; 2. for the less support of metal coverage rate, though the pliability of support makes moderate progress, its radial support power can weaken, and the blood vessel of diseased region can't be opened blood is flowed again; 3. the elastical retraction characteristic of existing support is not good, brings influence can for clinical final result.
Summary of the invention
The present invention overcomes the deficiencies in the prior art, and a kind of double top-cover coronary bracket with good supporting power, pliability and elastical retraction is provided.
The present invention is achieved through the following technical solutions:
A kind of double top-cover coronary bracket, be to interconnect and the tube wall ring support that constitutes by the metal master unit, it is characterized in that: the metal master unit is interconnected and is formed by big serpentine rings section, Double Tops serpentine rings section, little serpentine rings section successively, the big serpentine rings Duan Yuxiao serpentine rings section of adjacent metal main unit interconnects by single apical ring, and preceding metal master unit adopts connecting rod to be realized being connected by the formed single apical ring of big serpentine rings Duan Yuxiao serpentine rings section with metal master unit, back by Double Tops serpentine rings section is formed in conjunction with apical ring.
And described preceding metal master unit realizes that with metal master unit, back the connecting rod that is connected is a straight-bar,, or n shape connecting rod.
And the revolution position, top of described Double Tops serpentine rings section, big serpentine rings section, little serpentine rings section is the dome section.
And the height of described big serpentine rings section is greater than little serpentine rings section height.
And two tops of described Double Tops serpentine rings section are the form of flushing.
Beneficial effect of the present invention and advantage are:
1. metal master of the present invention unit is made up of a big serpentine rings section, a little serpentine rings section and a Double Tops serpentine rings spacer segment, and this Double Tops serpentine rings segment structure has also just increased the support force of support simultaneously when increasing the backbone metal coverage rate.
2. Double Tops serpentine rings segment structure form of the present invention increases the backbone metal coverage rate, and connecting rod adopts n shape connecting rod architectural feature form, when being used for medicine and being coated with support, can effectively increase the drug loading of medication coat.
3. Double Tops serpentine rings section of the present invention substitutes single top serpentine rings segment structure, and the pliability that has increased support helps mounting system and is transported to diseased region, reduces mounting system destruction to blood vessel wall in course of conveying.
4. each serpentine rings section of the present invention (comprising big serpentine rings section, little serpentine rings section and Double Tops serpentine rings section) all has by dome section (replacement arc section) and snakelike section forms this feature, when it is coated with as medicine that support uses and need be when lesion struts fully, because of the distortion of dome section less, so the medication coat that carries above is not easy to come off, can reduces support like this and in the process of implantable intravascular, blood circulation be brought the probability of risk because of medication coat comes off.
5. the large and small serpentine rings section combination of Double Tops serpentine rings section of the present invention, and connecting rod adopts straight-bar or n shape connecting rod architectural feature form, increase the pliability of support, helped mounting system and be transported to diseased region, reduced mounting system destruction to blood vessel wall in course of conveying.
6. the metal master unit of double top-cover coronary bracket involved in the present invention is made up of a big serpentine rings section, little serpentine rings section and a Double Tops serpentine rings spacer segment, and connecting rod adopts straight-bar or n shape connecting rod architectural feature form, can effectively increase the elasticity of support, and has a less retraction characteristic, so that the final expansion back diameter of support is suitable for the lesion blood vessel diameter accurately, be a kind of coronary artery bracket with higher science.

Fig. 3 is the planar structure sketch map of embodiments of the invention 2.
The specific embodiment
The present invention is described in further detail by following examples, and present embodiment is illustrative, rather than determinate, can not limit protection scope of the present invention according to following examples.
Embodiment 1:
A kind of double top-cover coronary bracket, interconnect and the tube wall ring support that constitutes by a plurality of metal masters unit, its metal master unit is interconnected and is formed by big serpentine rings section 4, Double Tops serpentine rings section 1, little serpentine rings section 3 successively, the big serpentine rings Duan Yuxiao serpentine rings section of adjacent metal main unit interconnects by single apical ring 5, two tops of Double Tops serpentine rings section are the form of flushing, the revolution position, top of Double Tops serpentine rings section, big serpentine rings section, little serpentine rings section is the dome section, rather than arc section, the height of big serpentine rings section is greater than little serpentine rings section height.Preceding metal master unit adopts connecting rod 2 to be realized being connected by the formed single apical ring of big serpentine rings Duan Yuxiao serpentine rings section with metal master unit, back by Double Tops serpentine rings section is formed in conjunction with apical ring (not having label), and this connecting rod is a straight-bar.
Embodiment 2:
Before the metal master unit adopt connecting rod 6 to realize being connected by the formed single apical ring of big serpentine rings Duan Yuxiao serpentine rings section by Double Tops serpentine rings section is formed in conjunction with apical ring with metal master unit, back, this connecting rod is that the centre is made and turned round arciform n shape straight-bar.
Other all are same as embodiment 1.
