Description
Technical field
The invention belongs to medical instruments field, more particularly, to a kind of effective biological support of coronary blood.
Background technology
Coronary heart disease refers to that serious atherosis or spasm occur for the blood vessel-coronary artery for supplying cardiotrophin material, makes hat
Shape arteriarctia or obstruction, and thrombosis cause obliteration, cause a class heart disease of myocardial ischemia-anoxemia or infraction.
Coronary stenting turns into the standard treatments of Percutantnoeus coronary intervention.Degradable blood vessel inner support
The design of (BDS, also known as biological absorbable support) is to cause stent restenosis based on overcoming bare metal stent to be chronically implanted human body
And the image check artifact such as late period Thrombosis in sten, CT and MRI, occur the problems such as revascularization is difficult again.
BDS on the one hand can support blood vessels in a short time, reach the purpose of revascularization, on the other hand can finally drop in vivo
Solution.Therefore, BDS can reduce blood vessel elasticity retraction and acute occlusion, pre- anti-restenosis in short term in theory, can reduce for a long time in support
Thrombosis, shortens the Antiplatelet therapy time, reduces revascularization rate again, eliminates the artifact of the image checks such as CT and MRI,
Avoid bad complication caused by metal permanent support.
But BDS supports are compared with metal permanent support, its maximum deficiency is due to that BDS supports are mostly Polymer-supported
Frame, so its mechanical property is subject to certain restrictions, long-term use, which tends not to guarantee, the support force in the same manner as metallic support,
And it is easier the elastical retraction for occurring early stage.And support is to be used for a long time it is necessary to have enough mechanical support power, in blood
The high-risk stage of elastical retraction provides preferable mechanical support after pipe stricture dilation, will not be caved in the normal activity of patient.
Due to the structure design of support can influence the transporting of support, compliance, structural support, radial support power,
The attributes such as longitudinal strength, therefore there are to support different performances, its structure design becomes particularly important, existing polymer
The compliance of support and flexibility are general all preferably, and support force is often inadequate, therefore to design and can be used for a long time and can be with
Biodegradable polymer support is exactly mainly the support force for solving the problems, such as polymer support.
The content of the invention
In view of this, the invention is directed to a kind of effective biological support of coronary blood, to solve prior art
Present in problem.
To reach above-mentioned purpose, what the technical scheme of the invention was realized in：
A kind of effective biological support of coronary blood, including by some groups of corrugated gaskets of parallel distribution and positioned at institute vertically
The support unit of the connector composition axially extended between corrugated gasket is stated, the two ends of the support unit or middle section pass through
The connector insertion is connected with a calabash bunch component, and the calabash bunch component is by two waveforms that relatively radially mirror image is set
Ring group into, in the calabash bunch component between two closest mirror image flex points be provided with brace rod, the brace rod is in institute
State in calabash bunch component and be closely disposed adjacent or set at equal intervals.
Further, the support unit has proximally and distally been respectively connected to a calabash bunch group by the connector
Part.
Further, the middle section of the support unit is connected with a calabash bunch component by connector insertion.
Further, the brace rod on the calabash bunch component of the support unit middle section is " people " font
Structure.
Further, the brace rod is set in the calabash bunch component equal intervals, specially the adjacent branch of each two
One group of closest mirror image flex point is spaced between support muscle.
Further, the biological support by PLLA and rubber-like polymer shape memory random copolymer system
Into.
Further, the connector in the support unit is staggered.
Further, " W " shape is provided with one between two adjacent corrugated gaskets in the support unit
Individual connector.
Relative to prior art, the effective biological support of coronary blood described in the invention has the advantage that：
Biodegradable scaffold described in the invention, is prepared from by PLLA, with biodegradability,
It with metal phase than maximum inferior position be exactly that easy resilience is unstable, and support force not enough, the structure of the invention is
Improvement to existing supporting structure, further improves the stability and radial support rigidity of degradable biological support, said structure
So that whole support take into account compliance, transporting, compliance it is preferable under the premise of, also with the radial direction suitable with metallic support
Support stiffness and longitudinal strength, improve the integrally-built mechanically supportive of polymer support so that polymer support is in length
In the case of phase use, preferable mechanical support can be still provided, elastical retraction is not susceptible to；And the support is degradable, both
Environmental protection and safety.
