Detailed description of the invention
As shown in Figure 1 and Figure 2, the present embodiment is a kind of carotid artery overlay film frame, has two ends diameter not
With horn-like skeleton (making for Nitinol or other current common used materials), this horn-like skeleton is from directly
Little one end, footpath is divided into far-end submissive section 1, intermediate supports section 2 and near-end grappling section to one end that diameter is big
3, the outer surface in intermediate supports section 2 and near-end grappling section 3 all cover overlay film (terylene or other commonly use at present
Raw material is made).
In the present embodiment, horn-like skeleton is formed by a class support ring 4 and two class support ring 5 Hybrid connections.As
Shown in Fig. 3, a class support ring 4 is made up of some ring-opened monomer 41 with opening, and ring-opened monomer 41 is
The sinusoidal wave structure of an a kind of wavelength, in this example, a class support ring 4 is the sine wave of some wavelength
Shape structure concatenation formed circulus.As shown in Figure 4, two class support rings 5 are the closed loop of some closings
The circulus that monomer 51 concatenation is formed, wherein closed loop monomer 51 is the sinusoidal wave form knot of two kinds of wavelength
Structure is combined into, and two kinds of sinusoidal wave structure wavelength are equal, and the half wavelength that staggers arranges (a sine wave
The crest of shape structure is corresponding with another trough), two kinds of sinusoidal wave structure combine and form two closed loop knots
Structure.In this example, a class support ring 4 and two class support rings 5 are formed by sinusoidal wave structure, and sinusoidal wave form is tied
Structure makes support ring possess enough radial direction support forces, and the hole of similar round reduces overlay film and tremulous pulse further simultaneously
Interior intermembrane space, prevents the complication such as internal fistula.
In this example, far-end submissive section 1 is connected by some class support rings 4 along its axial distribution and is formed, adjacent
Two class support rings 4 half wavelength that staggers arrange, the crest in one of them class support ring 4 is with another
Wave trough position in one class support ring is corresponding so that far-end compliance more preferably, more adapts to carotid canal big
The structure that amplitude is turned round.By the some S-shaped connecting rods 6 being evenly arranged between adjacent two pavilion one class support rings 4
Being connected, connecting rod 6 two ends are connected to crest and the trough of sinusoidal wave structure in adjacent two 1 class support rings respectively
Position.Using a class support ring 4 of ring-opened monomer composition in far-end submissive section 1, longitudinal compliance is good, can fit
Answer carotid artery and the tortuous feature of carotid canal entrance.
Intermediate supports section 2 is spaced friendship by some class support rings 4 along its axial distribution and two class support rings 5
Formed for connecting, all connected by the some S-shaped being evenly arranged between one, two adjacent class support rings 4,5
Bar 6 is connected, and connecting rod 6 two ends are connected to the crest of sinusoidal wave structure in adjacent one, two class support rings respectively
And wave trough position.Intermediate supports section 2 reduces between overlay film and endarterium by reducing matrix porosity area
Space, exists simultaneously as a class support ring 4 and two class support rings 5 are interrupted, is not affecting longitudinal compliance
In the case of increase radially support force, thus can fully oppress hematoma.
In the present embodiment, near-end grappling section 3 is connected by some two class support rings 5 along its axial distribution and is formed,
Between adjacent two two class support rings 5, the some S-shaped connecting rods 6 by being evenly arranged are connected, connecting rod 6
Two ends are connected to crest and the wave trough position of sinusoidal wave structure in adjacent two 2 class support rings respectively.Pass through near-end
Grappling section 3 uses the two class support rings that closed loop monomer forms, and increases radially support force, and near-end grappling section 3 is tight
Patch arterial wall inner membrance, it is to avoid fistula-induced complication after the implantation of carotid artery overlay film frame, it is possible to strengthen port support power
Piggy-back anchor fixed rack prevention stenter to implant retrodisplacement.
In the present embodiment, skeleton is in " tubaeform ", " loudspeaker " two ends (i.e. near-end grappling section 3 lower end and far-end
Submissive section of 1 upper end) different diameters 0.5-1mm, adapt to the carotid sinus metamorphosis to carotid artery far-end, anti-
Only produce gap between mount proximal end and endarterium, help anchor supports simultaneously.Horn-like skeleton diameter is little
One end a diameter of 4～7mm, a diameter of the 5 of one end that diameter is big～8mm；Far-end submissive section 1
Long about 5mm, intermediate supports section 2 long 20～40mm, near-end grappling section 3 long 1～about 5mm.
Certainly, described above is not limitation of the utility model, and this utility model is also not limited to above-mentioned act
Example, those skilled in the art, in the range of this utility model, the change made, change and add
Add or replace, all should belong to protection domain of the present utility model.
