Abstract
The utility model is related to a kind of effectively prevent cardiac stent of the secondary thrombus with nano biological coating.A kind of effectively to prevent cardiac stent of the secondary thrombus with nano biological coating, it is mainly configured with：Woven wire, drawknot silk, biological coating, are fixed between the woven wire sags and crests of described every two transverse directions by drawknot silk phase drawknot；Described drawknot silk is enclosed with biological coating in multiple curved arc shapes at its curved arc shape.Compared with the second generation film coating bracket that current tradition is used, it has film fineness higher to the utility model, employs the thickness of nanometer unit rank；It is more clear and definite that secondly coating location is set, employs and coating is set at independent drawknot silk；In addition the cardiac stent for designing is novel, is easy to medical care person to be organized work after support is stretched into.
Description
Technical field
The utility model is related to a kind of effectively prevent cardiac stent of the secondary thrombus with nano biological coating.
Background technology
Cardiac stent is the medicine equipment commonly used in interventional cardiac procedures, with dredging artery also known as coronary stent
The effect of blood vessel.Cardiac stent appears in the eighties in 20th century earliest, experienced metallic support, film coating bracket, Soluble Stent
Course of development, main material be stainless steel, Nitinol or cochrome.First generation metallic support, researches and develops coronary artery branch
The initial challenge of frame is how to be made it not only tough but also hard.Support is tough, then can, Branch Angle indefinite by direction it is larger
Coronary artery；Support is hard, then can prop up the artery stenosis inner chamber for having been expanded, it is not bounced back.Support Design engineer
In selection and construction, by unremitting effort, a variety of problems are solved, first generation artery branch has been successfully produced out finally
Frame.Second generation film coating bracket, after metallic support is successfully used to clinical treatment, second challenge is how to overcome human body pair
" attack " of support.Originally, support was treated as foreign matter by body, and impingement is treated as at the position that support and artery film are contacted.Have
Wound, human body will be repaired to it.Then, inflammatory reaction just occurs at the support of artery.Many patients, especially sugar
, there is serious scar tissue hyperplasia around metallic support in urine patient.This scar tissue hyperplasia, can make when serious
It is again narrow into unimpeded artery, or even block.Researcher through great efforts, is finally combined one medicine and support
Rise, that is, in one layer of medicine film of metal support surface " plating ".After in this stenter to implant body, medicine will be slowly released
Come, suppress scar tissue in support surrounding growth, keep coronary artery unobstructed.Worry that support stimulates local organization as foreign matter
After misgivings are eliminated, the trick of doctor is just decontroled, and the length of support and is also increased using scope.Some patients are even implanted into 2
~3 end to end supports, " exploit success " before and after original narrow positions.This support crossed through drug-treated is
Second generation arterial bracket.
The content of the invention
The purpose of this utility model be to provide it is a kind of effectively prevent cardiac stent of the secondary thrombus with nano biological coating, be
The derivative in-depth product of pointed current second generation film coating bracket in background technology.
The utility model solves its above-mentioned technical problem and uses following technical scheme：One kind effectively prevents secondary blood
Cardiac stent of the bolt with nano biological coating, it is mainly configured with：Woven wire, drawknot silk, biological coating, described every two
Fixed by drawknot silk phase drawknot between horizontal woven wire sags and crests；Described drawknot silk is in multiple curved arc shapes, and its curved arc
Biological coating is enclosed with shape.
Further, described biological coating thickness is 750-1200 nanometers.
Further, described biological coating is antithrombotic agent.
Further, the curved arc shape quantity of described drawknot silk is 3-7.
The beneficial effects of the utility model：Compared with the second generation film coating bracket that current tradition is used, it has film fine
Du Genggao, employs the thickness of nanometer unit rank；It is more clear and definite that secondly coating location is set, employs at independent drawknot silk
Coating is set；In addition the cardiac stent for designing is novel, is easy to medical care person to be organized work after support is stretched into.

Specific embodiment
1-3 makes a detailed explanation to specific embodiment of the present utility model below in conjunction with the accompanying drawings.
Embodiment：A kind of effectively to prevent cardiac stent of the secondary thrombus with nano biological coating, it is mainly configured with：Metal
Silk screen 1, drawknot silk 2, biological coating 3, by drawknot 2 phase drawknots of silk between the sags and crests of woven wire 1 of described every two transverse directions
It is fixed；Described drawknot silk 2 is enclosed with biological coating 3 in multiple curved arc shapes at its curved arc shape.
The described thickness of biological coating 3 is 750-1200 nanometers.
Described biological coating 3 is antithrombotic agent.
The curved arc shape quantity of described drawknot silk 2 is 3-7.
The core of the utility model design：Drawknot silk 2 is employed between the every two one metal wires net 1 of one to fix, and drawknot
The physical aspect of silk 2 in multiple curved arc shapes, the optimum point of this design is supportted in support after cardiac stent implantable intravascular
During opening, can effectively prevent cardiac stent from excessive deformation occurring and causes to cause vascular wall certain damage.
Because being exactly in fact the process that is straightened when woven wire 1 is softened process, this certainly will cause between the sags and crests of woven wire 1
Apart from elongated, because drawknot silk 2 is in multiple curved arc shapes, therefore this extended problem can be easily overcome.
Secondly being exactly that biological coating 3 is enclosed with curved arc shape, traditional second generation film coating bracket is to employ full width film
Layer, this mode effect on driving birds is not good, analysis reason due to rigidity and needs bullet to inhale to exist precisely due to the stressed member of woven wire 1
The requirement unusual light that therefore surface inherently manufactures in vascular wall, therefore coating is done on stressed member, its durability is not good, branch
The medicine of frame is very big to be used light.The design's simply devises coating on drawknot silk 2, and drawknot silk 2 is not stressed member, is
A kind of connector, and due to being provided with multiple curved arc shapes, each of which coating spreads that area is also big out, therefore, it is possible to the medicine of storage
Thing amount is not also small.
General principle of the present utility model, principal character and advantage of the present utility model has been shown and described above.One's own profession
The technical staff of industry it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply illustrate principle of the present utility model, on the premise of the utility model spirit and scope are not departed from, the utility model is also
Various changes and modifications are had, these changes and improvements are both fallen within the range of claimed the utility model.The utility model
Claimed scope is by appending claims and its equivalent thereof.
