Description
Technical field
The utility model relates to a kind of angiocarpy brackets, and the angiocarpy bracket of medicine is carried more particularly, to a kind of blind hole.
Background technique
Percutaneous Intracoronary Arterial Stenting is the main means of percutaneous coronary intervention (PCI), and it is total to account for about whole world PCI
70% or more of number of cases.Although Coronary Stent can be effectively reduced narrow again after percutaneous transluminal coronary angioplasty (PTCA)
Narrow rate, but still have the case of 20%-30% that in-stent restenosis (ISR) can occur, diabetes, Small vessel, Long lesion,
In Chronic total occlusion and bifurcated lesions patient, ISR incidence may be up to 30%-70%.Therefore, ISR has become influence
The most important reason of PCI long-term efficacy.
In recent years, to capture this problem of ISR, related control method is continued to bring out, and wherein coating stent of medicine is mesh
It is preceding to generally acknowledge one of most promising method.In order to prevent after stenter to implant human body restenosis generation, it is some that mucous membrane can be prevented raw
Long drug is applied to the surface of bracket.Compared with traditional operation, coating stent of medicine wound is small, and bleeding is few, operating time
It is short, restore fast, significantly reduces patient suffering, reduce operation risk, trouble can be saved to the maximum extent in a short period of time
The life of person.But since bracket is strutted after being sent to hemadostewnosis by sacculus, shape has very big change, especially some songs
The knee of the biggish connection strap of rate, the change of shape are also very big, it is easy to and the medication coat coated here is fallen off,
The Bulk drug to fall off is sprung up with blood flow, it is likely that is formed thrombus, is caused new harm.
Summary of the invention
The utility model is easy to draw afterwards aiming at existing angiocarpy bracket percutaneous transluminal coronary angioplasty (PTCA)
Hair in-stent restenosis easily falls off thrombosed technical problem coated in the medication coat on bracket, and providing one kind has
Effect reduce percutaneous transluminal coronary angioplasty (PTCA) afterwards restenosis rate, be effectively reduced and cause blood since medication coat falls off
The blind hole of bolt risk carries medicine angiocarpy bracket.
For this purpose, the connection that the utility model is equipped with several main supporting unit rings and is connected between main supporting unit rings
Bar, main supporting unit rings are longitudinally arranged successively along angiocarpy bracket, symmetrical in mirror surface between every main supporting unit rings of two adjacent groups
Distribution, each group of main supporting unit rings include several unit waves, and unit wave is arranged successively along the circumferential direction of angiocarpy bracket, unit wave
By the set of transitions of corolla arc, support rod and connection corolla arc and support rod at support rod is equipped with blind hole, each unit wave
Set 24 blind holes on support rod, each diameter of blind hole is 0.03mm, depth 0.03mm, and the blind hole 7 on each support rod is in
It is arranged in a straight line.
Preferably, blind hole accounts for the 40%-60% of main supporting unit rings area in the area of rack surface.
Preferably, support rod and transition width are wider than corolla arc width.
Preferably, adjacent main supporting unit rings are connected by connecting rod forms tubular annular support.
Preferably, the radian of corolla arc is greater than 180 degree.
Preferably, the material of intravascular stent platform is stainless steel, cobalt-base alloys or magnesium alloy.
The utility model structure is simple, can effectively reduce percutaneous transluminal coronary angioplasty (PTCA) restenosis rate afterwards；
Drug can be applied directly in blind hole, cause coating shedding after will not strutting because of sacculus, be greatly reduced since drug applies
Layer, which falls off, causes the risk of thrombus.Moreover, the mode of blind hole administration can make that the poly- cream unrelated with treatment need not be contained in coating
Acid eliminates polymer as foreign matter stimulation body and forms the possibility that branch contaminates interior thrombus.
Detailed description of the invention

Fig. 2 is the partial enlarged view of the utility model unit wave.
Symbol description in figure:
1. main supporting unit rings；2. connecting rod；3. unit wave；4. corolla arc；5. changeover portion；6. support rod；7. blind hole.
Specific embodiment
Specific embodiment of the present utility model is described in detail with reference to the accompanying drawings.
As shown in Figure 1 and Figure 2, the utility model is equipped with several main supporting unit rings 1 and is connected to main supporting unit rings 1
Between connecting rod 2, main supporting unit rings 1 are longitudinally arranged successively along angiocarpy bracket, every main supporting unit rings 1 of two adjacent groups it
Between it is symmetrical in mirror surface, each group of main supporting unit rings 1 include several unit waves 3, circumferential direction of the unit wave 3 along angiocarpy bracket
It is arranged successively, unit wave 3 is made of corolla arc 4, support rod 6 and connection corolla arc 4 and the changeover portion 5 of support rod 6, on support rod
Equipped with blind hole 7, shape is circle.Blind hole 7 is medicine storehouse, and drug is applied directly in blind hole 7.Since blind hole 7 is in angiocarpy
Bracket compress or while strutting do not occur or it is few deformation occurs, avoid the opposite shifting of medication coat and metal support surface
It is dynamic, it fundamentally solves the problems, such as coating shedding, improves adhesive force of the drug on bracket.And current most of drug
Bracket is in metal surface coated medicament, so that the concentration of intravascular drug is larger, rate of release is very fast, and release direction also obtains
Less than effective control, prevent a part of drug is by vascular wall from being absorbed, and the angiocarpy bracket of blind hole administration can extend medicine
The release time of object, the restenosis rate after reducing stenter to implant human body.
The 6 muscle width of support rod of the utility model unit wave 3 is 0.170mm, with a thickness of 0.110mm, length 20.8mm, branch
The width of strut 6 and changeover portion 5 is wider than the width of corolla arc 4, and the radian of corolla arc 4 is greater than 180 degree.
24 blind holes 7 are set on the support rod 6 of each unit wave 3, the diameter of each blind hole 7 is 0.030mm, and depth is
0.030mm, the blind hole 7 on each support rod 6 are arranged in a linear, and it is single that area of the blind hole 7 on angiocarpy bracket surface accounts for main support
The 40%-60% of 1 area of member ring.The structure of unit wave 3 and the depth of blind hole 7 are to influence the important ginseng of angiocarpy bracket performance
Number, angiocarpy bracket provided by the utility model will not influence the mechanical property of bracket because of blind hole 7.Preferably, blind hole 7
It is made by optical-fiber laser.
The material of angiocarpy bracket determines the most important factor of bracket performance, it determines the compliance, soft of angiocarpy bracket
The physical characteristics such as visuality, transporting, biocompatibility under cutting property, elastical retraction, straight radial strength, line, the utility model
Bracket material is stainless steel, cobalt-base alloys or magnesium alloy, has ensured the superperformance of angiocarpy bracket.
Only as described above, only specific embodiment of the utility model, when the utility model cannot be limited with this
The range of implementation, therefore the displacement of its equivalent assemblies, or according to equivalent changes and modifications made by the utility model patent protection scope,
It should still belong to the scope that the utility model claims book is covered.
