Description
Technical field
The present invention relates to implantable vessel fields, more specifically refer to a kind of follow-on arch of aorta overlay film frame
Type blood vessel.
Background technique
The Chinese invention patent that Authorization Notice No. is CN 102973303B is that a kind of arch of aorta of the applicant's invention covers
Membrane support type blood vessel, including an initiative pulse support blood vessel and three bifurcated artery stented vessels, on the initiative pulse support blood vessel
Open up one section of recessed portion, the recessed portion include the left side wall close to proximal part, the right side wall far from proximal part and connection it is left,
The bottom wall of right side wall, the left side wall of the recessed portion open up two openings, and right side wall opens up one or two opening, each opening
Inside fix one section of bore and the comparable inner chimney bracket that is open, the inner chimney bracket is along the aorta for deviating from recessed portion direction
Stented vessel side wall extends, and the bifurcated artery stented vessel is sub-packed in the inner chimney bracket.
When operation, the aortic stents of confined state are sent to by the thinner transportation system of a set of caliber to vascular lesion
Position.However, since two inner chimney brackets on side wall same in aortic stents are along the active for deviating from recessed portion direction
Pulsation frame blood vessel side wall extends, and two inner chimney brackets interfere radially when compressing, and affects entire aortic stents
The compression of blood vessel.And aortic stents are upon discharge, two inner chimney brackets are overlapped radially, give bifurcated artery bracket
The conveying and release of blood vessel bring difficulty, may cause two bifurcated artery stented vessels while conveying and release are same interior
In chimney bracket.In addition, existing initiative pulse support blood vessel is mostly straight tubular structure, released delivering into aortic arch
After putting, the screen resilience that both ends generate is larger, carrys out larger compressing to the zona vascuiosa of its corresponding position, or even make angiorrhoxis.For
This, present inventors have proposed a kind of follow-on arch of aorta overlay film frame type blood vessels.
Summary of the invention
The present invention provides a kind of follow-on arch of aorta overlay film frame type blood vessel, to solve existing arch of aorta overlay film
Stent affects entire aorta there are interfering radially when the compression of the inner chimney bracket of two laid out in parallel
The compression of stented vessel, and two inner chimney brackets are overlapped in the axial direction, conveying to bifurcated artery stented vessel and is released
Put the disadvantages of bringing difficulty.
The present invention adopts the following technical scheme:
Follow-on arch of aorta overlay film frame type blood vessel, including an initiative pulse support blood vessel and three bifurcated artery bracket blood
Pipe, the initiative pulse support blood vessel are successively spliced to form an approximate arc by proximal part section, recess section and distal end section
Multistage cable architecture, the left part and right part of the recess section pass through overlay film one and overlay film two right side with the proximal part section respectively
Side wall and the connection of the left side wall of distal end section, the right side wall middle and upper part of the proximal part section offer opening one, close to described remote
Opening two is offered straight up on the recess section bottom wall top surface of heart end section left side wall, in the left side wall of the distal end section
Top offers opening three, respectively corresponds in the opening one, opening two and opening three and is fixed with inner chimney bracket one, inner chimney
Bracket two and inner chimney bracket three, the inner chimney bracket one and inner chimney bracket three are respectively along the master away from recess section direction
Arterial bracket vessel side parietal suture closes, the fixed lower end surface for being sewn to the recess section roof of the inner chimney bracket two, the interior cigarette
Chimney bracket two is extended from described be open at two to the left part direction of the recess section, three bifurcated artery stented vessels point
Loaded in the inner chimney bracket one, inner chimney bracket two and inner chimney bracket three.
Further, the lower section that the inner chimney bracket two is connect with the opening two has one big curved side.
Further, the left side wall of the distal end section is an inclined surface, the roof shape of the inclined surface and the recess section
At an obtuse angle structure, the opening three is the angular cut being provided on the inclined surface.
Further, the longitudinal section of the recess section roof is the arc-shaped to raise upward, or the longitudinal section of recess section
For circle.
Further, the overlay film one and overlay film two are cyclic structure wide at the top and narrow at the bottom, two top of overlay film one and overlay film
Maximum length be 3~12mm.
Further, the right part of the inner chimney bracket one protrudes from the opening one, protrude length be 3~
5mm。
Further, be fixed on the top of one excircle of inner chimney bracket at the opening one, bottom end, front end and after
End is respectively equipped with a 8 font developing marks, protrudes from the one front end excircle of the inner chimney bracket of the opening one
Top, bottom end, front end and rear end are also respectively equipped with a 8 font developing marks.
Further, be fixed on the left end of two excircle of inner chimney bracket at the opening two, right end, front end and after
End is respectively equipped with a 8 font developing marks.
Top, bottom end, front end and the rear end for three excircle of inner chimney bracket being fixed at the opening three are set respectively
There are a 8 font developing marks.
Further, a plurality of rings that the initiative pulse support blood vessel is sewn in tubular film one by tubular film one and interval
Shape waveform bracket one is constituted, and the inner chimney bracket one, inner chimney bracket two and inner chimney bracket three include a tubulose
A plurality of ring waveform brackets two that film two and interval are sewn in the tubular film two, wherein the axial direction of inner chimney bracket two
The corresponding initiative pulse support blood vessel position of projection is provided only with tubular film one, in inner chimney bracket one and inner chimney bracket three
The outside of two neighboring ring waveform bracket two is correspondingly provided with a ring waveform bracket one, and the width of two annular supports two
The sum of degree is equal to its corresponding one width of ring waveform bracket.
By the above-mentioned description to structure of the invention it is found that compared to the prior art, the present invention has the advantage that
1, initiative pulse support blood vessel of the invention is spliced by proximal part section, recess section and distal end section, and every section opens up
One is open, and one inner chimney bracket of corresponding installing, three inner chimney brackets are in staggered distribution in the axial direction, can prevent in each opening
It is interfered with each other when only two inner chimney brackets at proximal part compress, so that initiative pulse support blood vessel is easier compression and be placed into diameter
Smaller transportation system, seal wire and conduit more easily choose each inner chimney bracket respectively, facilitate the conveying of bifurcated artery stented vessel
And release, prevent multiple bifurcated artery stented vessels from entering in the same inner chimney bracket.
2, initiative pulse support blood vessel of the invention, by proximal part section, recess section and distal end section splice, formed one
It is under natural conditions the multistage cable architecture of approximate arc, so that initiative pulse support blood vessel is after aortic arch release, both ends
The phenomenon that screen resilience in portion is smaller, will not oppress its corresponding zona vascuiosa and cause angiorrhoxis generation.
3, initiative pulse support blood vessel position corresponding to the axis projection of inner chimney bracket two be provided only with tubular film one without
Comprising ring waveform bracket one, not by the ring waveform bracket one on initiative pulse support blood vessel when guaranteeing two radiography of inner chimney bracket
It is blocked, seal wire and conduit is made quickly to choose inner chimney bracket two.
