Description
Technical field
The present invention relates to arterial bracket technical field, especially one kind effectivelying prevent interior leakage, realizes graft lesion artery
Anti- interior leakage that is completely enclosed, reducing complication generation and the art component with spring ring chimney holder.
Background technology
Aortectasia lesion either takes traditional open surgery still because usually involving important internal organ branch vessel
Endovascular graft, all great challenge.For complex lesions, the process of intracavity implant implantation may hinder the blood of branch vessel
It flows and causes severe complication.Chimney prosthetic ensure that blood flow by the bifurcated artery that intracavity implant is covered accidentally for those
Perfusion.Chimney prosthetic refers to during being placed in aortic prosthesis, because of the intentional covering of anchorage zone deficiency needs or not
When careful close significant branch openings, overlay film frame or bare bracket are discharged side by side between capped branch vessel and aorta,
Achieve the purpose that save or save capped branch vessel blood supply from damage.Because the release form of branch vessel inner support is similar to chimney, therefore
Referred to as chimney technology.In recent years, chimney technology is widely used in actively due to its flexible combination, convenient the characteristics of using
Arteries and veins is expanded in the endovascular stent-grafts exclusion that lesion retains internal organ branch blood flow.
About chimney technology, worry the most main is the generation of postoperative interior leakage.Interior leakage refers to and Endoluminal repair
Object is relevant outside graft chamber, and duration blood occurs in the aneurysm cavity and adjacent blood vessel intracavitary treated by this graft
The phenomenon that stream.Leakage in I types：Interior leakage or graft are mutually leaked inside the Pass also known as around graft.Because graft proximal end or distal end with
Fail to completely enclose between lesion artery and fails to complete closing or overlapped between either overlapped graft
Occur gap between graft, blood flow duration is caused to flow into aneurysm cavity.
Need it is a kind of effectivelying prevent interior leakage, realize that graft lesion artery is completely enclosed, reduces complication and occur it is anti-in
Leakage and the art component with spring ring chimney holder.

Specific implementation mode
Below in conjunction with the drawings and specific embodiments, the present invention will be further described.
Leakage and the art component with spring ring chimney holder in anti-, including：Main body rack 1,1 inside of main body rack is first
The first overlay film 12 is wrapped up in the outside of supporting rack 11, the first supporting rack 11, and main body rack 1 is circle, and side forms package after being pressurized
The groove of chimney holder 2, the contact position of groove and chimney holder 2 are equipped with the first staple fibre 13, and the inside of chimney holder 2 is the
Two supporting racks 21, the external of the second supporting rack 21 wrap up the second overlay film 22；The longitudinal direction of spring ring 3, spring ring 3 is artificial equipped with second
Fiber 31, spring ring 3 are wrapped on chimney holder 2, and chimney holder 2 and spring ring 3 are placed in main body rack by support inserting device 4
In 1 groove.
First supporting rack 11 is laterally waveform, and waveform is connected as an entirety longitudinally through connection strap.First covers
Film 12 is closed ring, is close to the outside of the first supporting rack 11.Second supporting rack 21 is laterally waveform, longitudinally through connection strap
Waveform is connected as an entirety.Second overlay film 22 is closing circular tube shaped, is close to the outside of the second supporting rack 21.Spring ring 3
