Description

A kind of super compliance nickel-titanium alloy intravascular scaffold
Technical field
The present invention relates to a kind of medicine equipment, more particularly to a kind of super compliance nickel-titanium alloy intravascular scaffold.
Background technology
At present, the intravascular Interventional Treatment of intravascular stent is increasingly becoming the primary treatments of hemadostewnosis disease, and it is former Reason is that implantation support generally reaches diseased region through induction system, and blood vessel is then rebuild after expansion, blood vessel is thus treated narrow It is narrow.This method has advantages below:Wound is small, few intercurrent disease, safe, patient suffering is few, be easily accepted by, the hospital stays is short And the patient of year high state of an illness weight is also resistant to.
In the performance indications of support, the submissive performance and spreading performance of support are imitated in surgical procedure and Post operation to clinic Fruit all plays vital effect.Submissive performance is had influence in art and postoperative support stretches the ability of blood vessel, reflects support The safety issue of product;Spreading performance is that influence blood vessel is in art because support is incomplete without expansion or expansion in art With postoperative recanalization rate, therapeutic effect is reduced.
Current support on the market, the main distinction is on the connection unit and form of carrier unit, due to unit arrangement Form is fixed, and the compliance and mechanical property of support simultaneously mismatch, and all respectively have biased.Such as single helical structure can improve The overall compliance of support improve support by performance, but the radial performance of support will be affected, in intravascular stent There may be " fish mouth " phenomenon, (when intravascular stent is bent, due to the influence of supporting structure, support is adjacent during generation aggressive bend Larger breach is produced between two stands unit, if shape fish mouth), or employ multiple connections singly between adjacent stent unit The structure of member, it can obtain axially upper relatively good stability, but its radial support, submissive performance can but be affected.

Preferably, the width of the carrier unit connecting rod for complying with section of described a kind of super compliance nickel-titanium alloy intravascular scaffold Spend the small 0.01-0.02mm of width than normal reach carrier unit connecting rod.
Preferably, the angle between described a kind of super compliance nickel-titanium alloy intravascular scaffold unit bar and bar is according to support Diameter it is different and different, angle angle can be 15 ° -50 °.
Preferably, normal reach carrier unit bar is straight-bar in the middle of a kind of described super compliance nickel-titanium alloy intravascular scaffold, Section carrier unit bar is complied with for waveform bar in two ends.
Brief description of the drawings
Fig. 1 is the axially expanded structural representation of support of the present invention.
Wherein, 1 is that support complies with section, and 2 be support normal reach, and 3 be support development mark, and 4 be normal reach support junction, 5 be carrier unit, and 6 be to comply with a section support junction.
Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, It is not intended to limit the present invention.
Embodiment one:
Referring to Fig. 1, the embodiments of the invention provide a kind of super compliance nickel-titanium alloy intravascular scaffold, entirety is in tubular construction, main To be applied in human vas, play a part of support blood vessels, so that intravascular flow is unobstructed, support includes successively connecting vertically Some carrier units 5 connect, the bearing of trend of each carrier unit 5 vertically is the length direction of support, each carrier unit 5 be that waveform is preferably the structure of sinusoidal wave successively around the cyclic structure formed radially in corrugated mode.
Support is integrally constituted by complying with section 1 and normal reach 2, complies with two ends that section 1 is support, and normal reach 2 is support Center section.The double sinusoidal structureds of the use of section 1 are complied with, that is, the crest of previous carrier unit 5 corresponds to next carrier unit 5 Crest.The quantity of the medium-height trestle unit 5 of section 1 is complied with according to how much determinations of support overall length, simply schematic diagram in figure is not represented most Whole quantity.Such pair of sinusoidal structured ensure that the super compliance at support two ends, it is ensured that the perfect release of support.Normal reach 2 is adopted Structure of the crest to trough, that is, the next carrier unit 5 of crest correspondence of previous carrier unit 5 trough, it is adjacent Two stands unit has four junctions 4, and adjacent junction 4 is staggering one by one for regularity, and this design ensures branch Frame interlude has enough support forces can ensure that to prop up diseased region.Compliance can be ensured in support by complying with the connecting rod 6 of section 1 While, and basic radial support power is not lost.Meanwhile, connecting rod 6 and this arrangement of junction 4 can effectively reduce branch " fish mouth " effect that frame is produced when bending.So that intravascular stent has good compliance and by performance, it is adaptable to complicated Lesion, the same time also has preferable spreading performance, radial support performance and expands uniform performance.
Support two ends are also with development mark 3, after stenter to implant human vas, and development mark 3 can show support position Put, help doctor to smoothly complete the positioning and release of support.
Embodiment two:
Referring to Fig. 1, support is during loading, and support complies with section 1 and can preferentially enter induction system, due to complying with section 1 Carrier unit is waveform, therefore radial load is relatively small, preferably can more effectively enter induction system.Comply with section entrance After induction system, for follow-up normal reach enter effective path is provided, the loading enhanced convenience for the integral support for being and soon It is prompt.
Likewise, system is in use, support is complied with section 1 and preferential can released from induction system, due to complying with the footpath of section 1 It is smaller to support force, and compliance grace can be good, therefore can more easily enter diseased region, the whole operation for being Efficiency greatly improve.Simultaneously because support normal reach 2 has good support force, therefore, it is possible to support narrow disease well Become position.There are such double effectses, the narrow problem of diseased region can be efficiently solved, and can entirely to perform the operation Journey is convenient stable, improves efficiency.
Preferred embodiments of the present invention are the foregoing is only, its structure is not limited to the above-mentioned shape enumerated, all at this Any modifications, equivalent substitutions and improvements made within the spirit and principle of invention etc., should be included in the protection model of the present invention Within enclosing.
