Abstract
The utility model relates to a double-top-ring bent lever coronary artery bracket. A tube wall ring shaped bracket is formed by mental body units which are mutually connected, the mental body unit is formed through a big snake shaped ring segment, a double-top snake shaped ring segment and a small snake shaped ring segment which are mutually connected in sequence, the adjacent big snake shaped ring segments and the small snake shaped ring segment of the mental body units are mutually connected through a single top ring; and a combination top ring formed by the double-top snake shaped ring segment of the front mental body is connected with the single top ring formed by the big snake shaped ring segment and the small snake shaped ring segment of the rear mental body unit through an n-shaped connection rod. The novel characteristic that the mental body unit of the double-top-ring bent lever coronary artery bracket is composed of a big snake shaped ring segment, a small snake shaped ring segment and a double-top snake shaped ring segment in an interval way provided by the utility model can improve the elasticity of the bracket efficiently and is provided with smaller retracting character, so that the diameter after the final expansion of the bracket is accurately and conveniently suitable for the diameter of thepathological blood vessel; the double-top-ring bent lever coronary artery bracket is a coronary artery bracket with higher scientific nature.
Description
Technical field
This utility model relates to the coronary artery bracket in medical material field, especially a kind of Double Tops ring curved bar coronary artery 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
This utility model is to overcome the deficiencies in the prior art, and a kind of Double Tops ring curved bar coronary artery bracket with good supporting power, pliability and elastical retraction is provided.
This utility model is achieved through the following technical solutions:
A kind of Double Tops ring curved bar coronary artery 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 n shape 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 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.
The beneficial effects of the utility model and advantage are:
1. metal master of the present utility model 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 utility model increases the backbone metal coverage rate, can increase the drug loading of medication coat when being used for medicine and being coated with support.
3. Double Tops serpentine rings section of the present utility model 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 utility model (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. large and small serpentine rings section combination and this version of n type connecting rod of Double Tops serpentine rings section of the present utility model, increased the pliability of support, help mounting system and be transported to diseased region, reduce mounting system destruction to blood vessel wall in course of conveying.
6. the metal master unit of the related Double Tops ring curved bar coronary artery bracket of this utility model is made up of and this character of innovation of n shape connecting rod a big serpentine rings section, a little serpentine rings section and a Double Tops serpentine rings spacer segment, 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. 2 is the planar structure partial enlarged drawing of Fig. 1.
The specific embodiment
This utility model is described in further detail by following examples, and present embodiment is illustrative, rather than determinate, can not limit protection domain of the present utility model according to following examples.
A kind of Double Tops ring curved bar coronary artery bracket, interconnect and the tube wall ring support that constitutes by a plurality of metal masters unit, its metal master unit is successively by big serpentine rings section 4, Double Tops serpentine rings section 1, little serpentine rings section 3 interconnects and forms, 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, Double Tops serpentine rings section, big serpentine rings section, the revolution position, top of 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 that the arciform n shape straight-bar of revolution is made in the centre.
Claims (4)
