Valve and the flashing valve interface being arranged on the main siphunculus side.
Existing some same stent-like systems are almost all compressed in transportation system using single long stent, and single is only
One piece of bracket can be provided, be not able to satisfy the demand for needing more pieces of brackets in single operation；Substantially increase operation time and
Risk reduces the validity that bracket uses；Moreover, human vas, tracheae or alimentary canal meander, and to bear surrounding flesh
Meat compression, torsion draw high contraction and pulsatile distension and the complicated physiology mechanical environment such as shrink, similar conventional stent system it is single
Long stent is generally difficult to bear so changeable physiological environment, is easy to happen bracket fracture, shifts and puncture body lumen etc. and ask
Topic；In addition, there is very long and biggish lumen contact area in conventional stent system in single interminable stenter to implant human body,
To generate more serious human body rejection, lead to lumen endometrial hyperplasia phenomenon, and this serious endometrial hyperplasia is directly made
At in-stent restenosis（ISR）Lesion influences the therapeutic effect of stenting；Furthermore after single interminable stenter to implant, due to mistake
More implantation contacts area can damage lumen and cause undesirable influence to internal fluid environment, such as affect fluid
To the shear stress normal distribution of tube wall and numerical value etc.；Finally, the single tediously long bracket of conventional stent system is when in use, in addition to covering
While lid lesion portion lumen, the lumen of some health is also covered, thus the phenomenon that causing unhealthful lumen.
But to overcome above-mentioned problem, not simply by doing big whole system by single bracket cutting or as far as possible
Etc. means, it is radial and axial it is found by the applicant that traditional if the supporting structure with sinusoidal waveform coiling is when being divided into multistage
Support strength can not effectively keep, structure peace preservation association becomes unstable, can not completely, equably expand, support effect
It has a greatly reduced quality；In addition, when being implanted into face of conventional stent cutting multistage, since support shaft all has elasticity energy and list itself upwards
The phenomenon that a scale of construction is smaller, and when release will appear the release position inaccurates such as more serious axial spring, this phenomenon causes
The probability that blood vessel is even worn out in damage is greatly improved.Through applicant's development test, the unit rack of the invention is used and is closed
Ring design, RF radial supporting force are stronger；For the jewel shape waveform element constituted with octagon closing framework, can effectively divide
Big strain is dissipated, by Strain Distribution to side peak, unit has bigger ductility；Compression diameter is small, and is easier in compression shape
The shape of structural unit is kept under state；Anti-pressure ability is strong, and support effect is good；Head end positioning does not have extremely strong offensiveness, reduces
The pressure of positioning；After release, expansion is complete, uniform, has preferably positioning shape, unit, which constructs, has bigger grasping force.And
Cooperate the anti-jump component of the unit rack, with simple and effective structure fusion into entirety, anti-jump component itself is motionless,
And the unit rack can be disconnected when close to release completely or release completely, the position of the unit rack is equally protected
Hold constant, and after unit rack release, the anti-jump component is to remove human body by the hollow portion of the unit rack.
Technological merit of the invention is specific as follows：
1, corresponding operating system can be used in the unit rack, realizes that single conveys and discharges more pieces of implantable or Interventional branch
Frame meets the case where primary intervention needs more pieces of brackets, reduces operating time, improve procedure efficiency；
2, more pieces short and small of bracket substitutes one piece of interminable bracket, structural strength itself stills remain in higher level, avoids
The case where bracket is broken in complex physiologic mechanical environment lower bracket, displacement, the effect of greatly improving operation；
3, more pieces short and small of bracket substitutes one piece of interminable bracket, and using a method for release treatment, non-large area covers lesion,
The lumen for effectively avoiding injury slight with unhealthful lumen and the state of an illness；
4, more pieces short and small of more piece bracket substitutes one piece of interminable bracket, farthest reduces lumen contact area, reduces different
Object reacts, and mitigates in-stent restenosis caused by endometrial hyperplasia in many degree（ISR）The phenomenon that.

On for being caught in the matching slot 121 in developing mark portion 111, under 11 collapsed condition of unit rack, the card of developing mark portion 111 is held in
In slot allocation 121, and during release, developing mark portion 111 is still designed to be stuck in matching slot 121 until releasing completely
It puts.One end without developing mark portion 111 of main paragraph 112（Can certainly have for both ends）With under swelling state
Gradual change outside be flared, bell shape is presented in the unit rack head end after expansion completely, convenient for positioning in 11 lumen of unit rack,
And unit rack 11 is not easy to shift, slide in the case where disposal environment complexity.It include multiple and quantity phase in Fig. 2, Fig. 3
Deng unit rack 11 and anti-jump component 12.Fig. 4 is the swelling state structure chart that unit rack 11 discharges completely.
Fig. 5 and Fig. 6 is the plane outspread drawing and its details of unit rack 11, and main paragraph 112 is included under collapsed condition
Bracket circumferential direction and axial direction are connected and organize integral triangular waveform unit, and triangular waveform unit has the shape under swelling state
At octagon close framework.Triangular waveform unit includes two sections of end to end folding shape ribs, and rolling over shape rib successively includes the
One muscle section 1121, the second muscle section 1122 and third muscle section 1123, the first muscle section 1121, the second muscle section 1122, third muscle section 1123
Folding shape is connected and to form triangle wavy, and two sections of folding shape ribs surround octagon and close framework.The head end of first muscle section 1121 and
The head end of three muscle sections 1123 is each provided with connection top section 1124, and the second muscle section 1122 closes the outer of framework relative to octagon
Side is equipped with connecting side section 1125.All connection top sections 1124 are intervally arranged into the week of bracket along bracket axial direction
Multiple concentric circumferences.All connecting side sections 1125 are intervally arranged into the week of bracket along bracket axial direction multiple same
Heart circumference.The structure of triangular waveform unit in diagram is that two zigzag ribs are formed in parallel, and is basic group of unit rack 11
At part, triangular waveform unit forms rack body by way of radial parallel, axial series.After unit rack 11 expands,
Triangular waveform unit forms an eight-sided formation, and irregular eight side closed-loop construct is presented, and sufficient radial direction is improved for bracket
Support force；And when surrounded between an adjacent triangular waveform unit and eight side closed-loop constructs, branch is further increased
