According to one embodiment of the disclosure, provides one kind and take bolt rack 12.As shown in Figure 1, taking bolt rack 12 in cylinder
Shape structure.Taking bolt rack 12 includes the multiple grid cells to link together.Take bolt rack 12 that there is axial clearance 22 and use
In formed axial clearance 22 first in 23 and second while 24.First side 23 forms multiple bulge-structures 26.Second side 24 is formed
Multiple sunk structures 27 corresponding with the structure of bulge-structure 26.First 24 is separated from each other at 23 and second and refers to the first side
23 and second side 24 do not formed and be connected to each other.In this way, first the distance between 24 can be according to blood vessel at 23 and second
Internal diameter is adjusted in time.For example, the shape of the bulge-structure 26 and shape of sunk structure 27 matches or sunk structure 27
Bulge-structure 26 can be surrounded.Bulge-structure 26 is opposite with the position of sunk structure 27.When taking bolt rack 12 to shrink, bulge-structure
26 can be inserted into sunk structure 27.Contraction of the bolt rack 12 in receiving state not is taken here, shrinking, but in extended state
When, it takes bolt rack 12 to become smaller with the internal diameter of blood vessel and shrinks.
It as shown in Figure 1, taking bolt rack 12 is open loop structure, and is in cylinder mould shape.The shape of grid cell is round, oval
Shape, diamond shape or ring structure.Multiple grid cells can be identical structure, be also possible to different structures.Wherein, different
The grid cell of structure links together, and can effectively improve the binding force for taking bolt rack 12 Yu thrombus.
Bolt rack 12 is taken to be made by memorizing material, for example, memorial alloy, memory high molecular material etc..This makes
Take bolt net amount of crimp can be adjusted according to the size adaptation of vessel diameter, to be bonded with the inner wall of blood vessel.For example,
Blood vessel is thinner, then the interlaced part in the both sides of open loop structure is more, to reduce outer diameter；Blood vessel is thicker, then open loop structure
The interlaced part in both sides is fewer, to increase outer diameter.The open loop structure can automatic adjusument diameter, to adjust radial support
Power reduces the damage to blood vessel.
Optionally, memorial alloy includes for Nitinol, nickel cobalt (alloy), ormolu, golden cadmium alloy etc..In the preparation,
Firstly, the sheet material of memorial alloy passes through laser ablation, to form the multiple grid cells to link together.The mode of laser ablation
Grid cell of various shapes can be formed according to actual needs, and formed precision is high.Then, by the first side 23 and second of material
Side 24 is cylindrical in shape structure towards opposite direction winding.In receiving state, the first 24 overlapping at 23 and second is tiny to be formed
Club shaped structure.After removing external force, which can reply original shape state, that is, be extended into tubular structure.
Remembering high molecular material includes polynorbornene, styrene-butadiene copolymer, shape memory polyurethane etc..Example
Such as, grid cell is formed by way of injection molding, laser ablation.Above-mentioned material all has good Memorability, can basis
The size of vessel diameter is shunk, is discharged.The size of axial clearance 22 changes with the variation of the internal diameter of blood vessel.
