Description
Technical field
This utility model relates to a kind of coronary artery balloon expandable stent, especially relates to a kind of coronary artery balloon expandable stent that can prevent the Os Canitis problem, is used for cardiovascular disease such as interventional therapy coronary occlusion.
Background technology
Cardiovascular disease has been acknowledged as one of the most serious disease of China and even world crisis people life and health, and its M ﹠ M occupies first of all kinds of diseases.At present, the treatment of coronary heart disease is divided into Drug therapy, surgical operation and interventional therapy three major types.The Drug therapy cycle is long, and it is slow to take effect, and side effect is big, and the patient is easy to generate the specified dependency of medicine; Surgical operation can produce nonvolatil injury to patient; Interventional therapy method is hindered and high efficiency because of its Wicresoft, becomes the narrow novel method of present treatment cardiovascular.Stent is at percutaneous puncture transluminal coronary angioplasty art (Percutaneous TransluminalCoronary Angioplasty, PTCA) on the basis, by foley's tube metal rack is delivered to lesion, and make its expansion back the passive a kind of operation method of blood vessel.
Existing coronary artery balloon expandable stent form has multiple, and every kind of design all has and stresses, because just there is the contradiction of each side in the design of support itself, the compliance of passing through such as radial support power and support, be difficult to reach simultaneously optimum efficiency, can only choose reasonable, take into account two aspects.But existing coronary stent is owing to the limitation on the project organization, and the axial LVFS of some support after expansion is big, makes support insert the risk that the back existence can not cover diseased region fully; Some support is in the process of opening, open in advance at both ends, cause the support axial retraction, two ends open that phenomenon can occur significantly that two ends are played and middle situation of not playing, this situation is called the Os Canitis phenomenon, the harm that the Os Canitis phenomenon is brought is apparent, and two ends were opened conference and caused the obvious damage of support to blood vessel, were unfavorable for the recovery of sufferer position.Axially LVFS and dog bone rate have close contact, and the dog bone rate seriously whether, be the important indicator of estimating the support performance, the support that the dog bone rate is high, very easily cause the damage of support, so current support Design still remains further to be improved to blood vessel.The support of being mentioned among the patent No. ZL 200620026251.8, because the unified waveform width of the whole employing of support, so very likely produce serious Os Canitis problem.
Summary of the invention
The purpose of this utility model is to provide a kind of expansion back, and axially LVFS is low, and the dog bone rate is low, and radial support power is big, the coronary artery balloon expandable stent that decorative pattern is evenly distributed.
This utility model is achieved through the following technical solutions:
A kind of coronary artery balloon expandable stent, this support are webmaster shape structure, and cradle wall is latticed hollow out wall, and grid is the circulation shape.Appearance for prevention Os Canitis problem, this support two ends cradle wall width is slightly smaller than mid-stent cradle wall width, the support that adopts this design is in the process of opening, the two ends lifting surface area reduces, can reduce the dog bone rate, and, the Pattern Design that two ends are thinner, after also making support implant diseased region, to the stimulation reduction of human vas.
Specifically, this support can be by the ultra-thin pipe of rustless steel through the molten webmaster shape structure that is carved into of laser, described webmaster shape structure is made up of a plurality of V-arrangement wavy annular structures, these circuluses are arranged above and below in regular turn, be mirror image between the adjacent two V-arrangement corrugated gaskets and distribute, crest and crest adopt connecting key to join between the adjacent two row V-arrangement corrugated gaskets.
Described webmaster shape structure adopts the closed-loop structure design, all adopts connecting key to join between each crest and the crest between the adjacent two row V-arrangement corrugated gaskets, and connecting key is evenly distributed in the tubulose network structure.The closed-loop structure design increases the radial support power of support.
The width of described V-arrangement corrugated gasket is greater than the connecting key width.This structure makes connecting key easier of axial stretching, extension after launching under the effect of support at sacculus, remedies the length of axial retraction, thereby whole axial retraction rate is reduced.
Described connecting key can be preferably S shape for in-line, V-arrangement, S shape, N shape or W shape etc.
Described support can also adopt the in-line connecting key to be connected between the waveform of edges at two ends and middle part waveform, adopt S shape connecting key to join between the adjacent waveform of mid-stent, the connecting key uniform distribution is arranged, thereby guarantee the circumferential stress balance of support, also improved the radial support power of support simultaneously.
The axial length of described S shape connecting key can improve the bending and the flexibility of support itself less than the V-arrangement waveform length, and the uniform distribution of S connecting key also makes the form after support launches more even, stressed balance more simultaneously.
The beneficial effects of the utility model are, this coronary artery balloon expandable stent can improve the bending and the flexibility of support itself, form after support launches is more even, the dog bone rate is low, axially LVFS is low, decorative pattern is evenly distributed, the circumferential stress balance of support, and improved the radial support power of support.
Below in conjunction with drawings and Examples this utility model is further specified.
Description of drawings
Fig. 1 is the developed surface enlarged drawing of coronary artery balloon expandable stent;
Fig. 2 is an embodiment of coronary artery balloon expandable stent;
Fig. 3 is the most preferred embodiment of coronary artery balloon expandable stent.
The specific embodiment
Referring to Fig. 1, coronary artery balloon expandable stent described in the utility model, this support is through the molten webmaster shape structure 1 that forms of carving of laser by the ultra-thin pipe of rustless steel, cradle wall is latticed hollow out wall, grid is the circulation shape, and the cradle wall width d at the port 4 of support and port 5 edges is less than mid-stent cradle wall width D.Adopt this design, can prevent the appearance of Os Canitis problem, support is in the process of opening, and the two ends lifting surface area reduces, and can reduce the dog bone rate, and, the Pattern Design that two ends are thinner, also make support implant diseased region after, the stimulation of human vas is reduced.Wherein said webmaster shape structure 1 can be made up of a plurality of V-arrangement corrugated gasket 2 structures, and these circuluses are arranged above and below in regular turn, is mirror image between the adjacent two V-arrangement corrugated gaskets and distributes, and crest and crest adopt connecting key 3 to join between the adjacent two row V-arrangement corrugated gaskets.Wherein the connection between the V-arrangement corrugated gasket can be an open-loop design 8, for example can be that two crests design a connecting key 3 at interval.
