The both ends partial image section of the often section segmentation holder 1 is trapezoidal.
The outside of anti-displacement sugarcoated haws formula segmentation overlay film recoverable support be nested with one layer it is independent and with segmentation branch
There are the pellosils 4 of mutual free gap for frame 1.
The segmentation holder 1 that often saves is woven by single titanium-nickel wire.
The outer rim of holder both ends rim of a cup 3 is covered with pellosil shirt rim, prevents hyperblastosis from growing in holder.
The hump shape includes dromedary hump shape and double hump shape.
2 waveform of the flexible cord is continuously arranged.
The rim of a cup 3 is generally bowl-shape, and main body is bowl shaped structure 31, has the arc-shaped outer surface heaved, stage casing
Diameter is more than the diameter at both ends, and for 31 one end of bowl shaped structure tool there are one opening 30, the other end is the cylinder being connect with segmentation holder 1
32, rim of a cup 3 is woven by single titanium-nickel wire.
The utility model has the beneficial effects that：
The anti-displacement sugarcoated haws formula of the utility model is segmented overlay film recoverable support as a result of independent unit rack
Structure solves the technical issues of holder poor compliance in holder overlay film integral structure in the prior art so that holder is easy to each
Kind bending angle, while the hump shape structure formed between sugarcoated haws holder can prevent stent migration, it is preferably accurate fixed
Holder.Because there is no hangnail or naked frame structure, keep holder recycling more convenient.

Specific implementation mode
The utility model is further described below in conjunction with the accompanying drawings：
Such as Fig. 1 to Fig. 3, embodiment one, a kind of anti-displacement sugarcoated haws formula segmentation overlay film recoverable support includes the cup at both ends
Segmentation holders 1 more than two sections of mouth 3 and connection both ends rim of a cup 3, the often section segmentation holder 1 is drum organization, that is, is had
Arc-shaped or hump shape outer surface, and the diameter in stage casing is more than the diameter at both ends, and both ends are open port, segmentation
Between holder 1 and segmentation holder 1 is connect with rim of a cup 3 by flexible cord 2, and the internal diameter of rim of a cup 3 is more than the internal diameter of segmentation holder 1, point
The maximum outside diameter of section holder 1 is bigger 4mm~6mm than minimum outer diameter.
Such as fig. 4 to fig. 6, embodiment two, a kind of anti-displacement sugarcoated haws formula segmentation overlay film recoverable support includes the cup at both ends
Segmentation holders 1 more than two sections of mouth 3 and connection both ends rim of a cup 3, the often section segmentation holder 1 is drum organization, that is, is had
Arc-shaped or hump shape outer surface, and the diameter in stage casing is more than the diameter at both ends, and both ends are open port, segmentation
Between holder 1 and segmentation holder 1 is connect with rim of a cup 3 by flexible cord 2, and the internal diameter of rim of a cup 3 is more than the internal diameter of segmentation holder 1, point
