Abstract
The invention discloses a film coating bracket which comprises a film coating pipe and a self-ejecting type bracket, wherein the self-ejecting type bracket is fixed on the film coating pipe by a suture line and comprises a plurality of self-expanding rings, and the self-expanding ring positioned at the end part of the film coating pipe has an integral waveform structure with a long edge and a short edge. By the integral design of the long edge and the short edge on the self-expanding ring positioned at the end part of the film coating bracket provided by the embodiment of the invention, the short edge constrains the long edge; and meanwhile, the suture depth of the self-expanding ring at the end part is increased, and the constraining function of the film coating pipe on the self-expanding ring at the end part is strengthened. Accordingly, the film coating bracket can provide enough constrain force for the part of the self-expanding ring at the end part, which is exposed out of the film coating pipe in the release process, thereby greatly reducing a turnover risk of the self-expanding ring at the end part during release.
Description
Technical field
The application relates to medical instruments field, particularly relates to a kind of overlay film frame.
Background technology
Aortic aneurysm is the lump on the main artery wall, and it is to be caused by the weak ductus arteriosus wall of blood pressure compressing, can be divided three classes by the position: ascending aorta tumor, aortic arch tumor, descending aorta tumor.It just has disruptive danger when aneurysm reaches a certain size, may cause patient's internal hemorrhage and life danger occurs.Present therapeutic modality mainly is to implant overlay film frame, makes it seal aneurysm internally, with the impact of alleviation blood pressure for weak aorta wall, thereby reduces its disruptive risk.
Overlay film frame comprises the overlay film pipe and is fixed on the eject support on the overlay film pipe through stitching thread usually have part eject support to expose in the overlay film tube outside in existing overlay film frame end, is called " naked section ".
Through the research to prior art, the applicant finds: because that " naked section " of eject support sews up the degree of depth of overlay film pipe is more shallow, its constraint that receives the overlay film pipe is less; Elasticity is bigger, and therefore in dispose procedure, " naked section " of eject support may turn down; And then cause the end of overlay film frame not to be fitted in preferably on the blood vessel wall; Cause I type internal hemorrhage due to trauma, " naked section " of the eject support of turnover also may thrust in the blood vessel wall simultaneously, and blood vessel wall is caused serious injury.
Summary of the invention
In view of this, the application embodiment provides a kind of overlay film frame, exposes the risk that turnover takes place when discharging at the eject support of overlay film tube outside on the existing overlay film frame to reduce.
For realizing above-mentioned purpose, technical scheme is following:
A kind of overlay film frame comprises: overlay film pipe and be fixed on the eject support on the said overlay film pipe through stitching thread, wherein:
Said eject support comprises a plurality of self-expanding rings, and the structure that is positioned at the self-expanding ring of said overlay film tube end is the integral type waveform configuration with high rib and short rib.
Preferably, said a plurality of self-expanding ring disperses to be arranged on the said overlay film pipe.
Preferably, said integral type waveform configuration is the mutual alternative structure of high rib and short rib.
Preferably, said short rib all is sewn on the said overlay film pipe, and said high rib is sewn on the said overlay film pipe by part.
Preferably, the body of said overlay film pipe is straight body.
Preferably, the material of said overlay film pipe body is PET or PTFE material.
Preferably, the material of said self-expanding ring is pure titanium, Nitinol, cobalt-base alloys and/or rustless steel.
Visible by above technical scheme; In the overlay film frame that the application embodiment provides; Be positioned at the design that overlay film tube end self-expanding ring adopts the one waveform configuration with high rib and short rib, and short rib is sewn to all on the said overlay film pipe, high rib half is sewn on the said overlay film pipe at least.Compared with prior art; The integral type of high rib and short rib design on the self-expanding ring of the end of this overlay film frame; Make short rib play the constraint effect, increase the stitching degree of depth of end self-expanding ring simultaneously, strengthened of the constraint effect of overlay film pipe end self-expanding ring to high rib.Therefore this overlay film frame can provide enough binding forces to the part that end self-expanding ring exposes outside the overlay film pipe in dispose procedure, and the risk of turnover takes place when discharging the end self-expanding ring that reduces greatly.
In addition; Short rib on the end self-expanding ring can also increase the contact point with the overlay film pipe; And contact point all with distribute, promote the rounding property and the adherent ability of overlay film frame end, and then can prevent effectively owing to the adherent bad internal hemorrhage due to trauma that causes in overlay film frame end.

The specific embodiment
In order to make those skilled in the art person understand the technical scheme among the application better; To combine the accompanying drawing among the application embodiment below; Technical scheme among the application embodiment is carried out clear, intactly description; Obviously, described embodiment only is the application's part embodiment, rather than whole embodiment.Based on the embodiment among the application, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all should belong to the scope of the application's protection.
The part-structure sketch map of the overlay film frame that Fig. 1 provides for the application.
As shown in Figure 1, this overlay film frame comprises: overlay film pipe 1 and eject support 2, wherein eject support 2 is fixed on the overlay film pipe 1 through stitching thread 3.
Eject support 2 comprises a plurality of self-expanding ring self-expanding rings 21, and a plurality of self-expanding ring 21 disperses to be arranged in the overlay film pipe 1, for overlay film pipe 1 is providing support power in the radial direction, prevents overlay film pipe 1 behind implant into body, extrusion.Among the application embodiment, can the space between a plurality of self-expanding rings 2 even, the self-expanding ring 2 that is positioned at overlay film pipe 1 middle part in addition preferably be sewn on the overlay film pipe 1 by part, guarantees to have certain crooking ability after overlay film frame discharges.
The deployed configuration sketch map of the overlay film frame end self-expanding ring that Fig. 2 provides for the application embodiment.The perspective view of the overlay film frame end self-expanding ring that Fig. 3 provides for the application embodiment.
As shown in Figures 2 and 3, the structure that is positioned at the self-expanding ring 21 of the overlay film pipe 1 end integral type waveform configuration that high rib 211 and short rib 212 are formed of serving as reasons, and short rib 212 all is sewn on the overlay film pipe 1, and high rib 211 is sewn on the overlay film pipe 1 by part.In the application embodiment, in the integral type waveform configuration, preferably with high rib 211 half is sewn on the overlay film pipe 1 at least, and high rib and short rib can replace each other, can also be that a high rib and two short ribs alternately distribute.The length range of high rib 211 is chosen in 16～30mm, and the length range of short rib 212 is chosen in 5～15mm; As shown in Figure 2, the scope of the angle on high rib 211 summits is chosen in 15～60 °, and the scope of the angle β on short rib 212 summits equally also is chosen in 15～60 °, and the number sum of high rib 211 and short rib 212 is preferably 8～14.Those of ordinary skills will be appreciated that the above preferred embodiment of the application embodiment that is, should not constitute the restriction to the application.
