Description
Technical field
The present invention relates to branched membrane-covered supports in department of cardiovascular surgery technical field more particularly to a kind of novel aorta.
Background technique
The dissection of aorta and aortic aneurysm that involve arch of aorta top set artery are the difficult points of vascular surgery.Open surgery
Time is long, surgical procedure is complicated, needs Deep Hypothermia Circulatory Arrest, easily leads to the neural complications such as bleeding and cerebral ischemia, have compared with
The high death rate.For endovascular graft, if foot can not be obtained by not blocking bifurcated artery using current intracavitary instrument
Enough anchorage zones, interlayer and aneurysm are unable to get effective treatment.But closure bow top set's artery is unacceptable completely,
Because this will lead to brain blood supply obstacle, and then it is even dead Ischemic Stroke occur.It is obtained enough so blocking bifurcated artery
To rebuild bifurcated artery again be the operating conditions for solving the problems, such as this simultaneously for anchorage zone, but safely, effectively implement this thinking and be
Where the shoe pinches clinically.Orthotopic fenestration, pre- windowing technology made some cases treatment obtain may, but its still without
Method solves the problems, such as to leak (the leakage blood between main support and small rack) in 3 types.Outer branch stent is insufficient there is also Free up Memory and
Need the problem of customizing.Therefore branched membrane-covered support is designed in a kind of novel aorta to solve the above problems, it will
Effectively improve aorta dissection and/or aneurysmal survival rate.
Summary of the invention
The object of the present invention is to provide branched membrane-covered supports in a kind of novel aorta, have by adding interior branch stent
Effect solves the problems, such as to leak blood between aorta tectorial membrane stent and branch's overlay film frame, while being designed by the abnormity of interior branch stent,
The bracket of universal models can be made to adapt to the demand of more patients, reduce the case where needing customization support, so as to shorten treatment week
Phase and the financial burden for reducing patient.
The technical solution of the present invention is as follows: branched membrane-covered support in a kind of novel aorta, is made of metal frame and overlay film,
Overlay film frame can adjust shape with blood vessel structure during beating, and match with aortic blood tube shape, including bow proparea, Gong Buqu
And bow back zone, the bow proparea, Gong Buqu and bow back zone are integrally formed, are made of the metal frame of tubulose overlay film and its outside,
The outside that metal frame is located at tubulose overlay film is played the role of fixed and is supported, and is big curved side, the bow portion at the top of the area Gong Bu
Area bottom is lesser curvature side, and the area the Gong Bu side great Wan is equipped with several interior branch stents, is at the top of any interior branch stent
Circular opening on big curved side, any interior branch stent can be divide into upper part and lower part, any interior branch stent top
It is greater than bottom section diameter for bowl structure top cross-section diameter, any interior branch stent lower part is cylindrical-shaped structure, interior
The cross-sectional diameter of branch stent lower cylindrical structure is not more than interior branch stent top bowl structure bottom section diameter, should
The effect of design is that interior branch stent top drilling can correspond to the bifurcated artery on bow portion artery top,
Any interior branch stent is an integral molding structure with the area Gong Bu, and junction is seamless.
Preferably, any interior branch stent top cross-section diameter is 10mm-25mm, on any interior branch stent
Portion's bowl structure bottom surface diameter of section is 8mm-15mm, the high 2mm-5mm of any interior branch stent top bowl structure.
By data statistics it is found that the bifurcated artery blood vessel number on the bow portion artery top of common people is 3, diameter is general
For 8mm-15mm, the interval between bifurcated artery is generally 2mm-10mm, therefore interior branch stent top cross-section diameter is 10mm-
When 25mm, 3 bifurcated arteries can respectively correspond 3 interior branch stent top drillings；
Preferably, any interior branch stent lower cylindrical feature cross-section diameter is 8mm-15mm, any described
The interior a height of 3mm-5mm of branch stent lower cylindrical structure.
Any interior branch stent lower cylindrical structure is as anchor region, for being secured across interior branch stent
Branch's overlay film frame.
Preferably, the area Gong Bu lesser curvature side is equipped with half release device, and half release device includes navigation seal wire and seam
Line, half release device are used to carry out overlay film frame after discharging for the first time, fully open overlay film frame can't, half release conditions
Lower overlay film frame sectional area is about the 70%-80% of overlay film frame sectional area under full open position, so as to its position
It is adjusted, thus the more accurate aperture respective branches artery made at the top of interior branch stent.
Preferably, navigation seal wire is equipped with inside the overlay film frame.
Preferably, the interior branch stent quantity is 3.
Further, 4 navigation seal wires are equipped with inside the overlay film frame, wherein after a navigation seal wire passes through bow
Area, Gong Buqu and bow proparea, in addition three navigation seal wires pass through bow back zone, are divided by being each passed through in corresponding one in the area Gong Bu
Branch bracket passes through bow back zone, Gong Buqu and bends the navigation seal wire in proparea for aorta tectorial membrane stent is more accurate
It is placed into sufferer position, the navigation seal wire in the navigation seal wire and half release device can be same, in addition three navigation seal wires
After effect is that aorta tectorial membrane stent places, branch's overlay film frame is accurately passed through respectively using this three navigation seal wires
Corresponding interior branch stent is put into corresponding bifurcated artery blood vessel.
Preferably, multi-cavity vagina vasorum is equipped at the navigation seal wire tail portion, 4 navigation seal wires are each passed through described more
One of chamber of chamber vagina vasorum, consequently facilitating the doctor to perform the operation preferably controls navigation seal wire for corresponding overlay film frame
It is put into designated position, prevents mutually winding between different navigation seal wires from influencing operation progress.
Preferably, the radian of the area the Gong Bu side great Wan is 60 ° -150 °.
Preferably, the overlay film material is macromolecule membrane, and the metal frame material is Nitinol.
Aorta tectorial membrane stent is sent to sufferer using a navigation seal wire when use, release aorta tectorial membrane stent is extremely
Half release conditions, fine tuning aorta tectorial membrane stent position make interior branch stent top drilling respectively correspond bifurcated artery, remove half
Release device fully opens aorta tectorial membrane stent, passes through branch's overlay film frame using other three navigation seal wires and corresponds to
Interior branch stent, and enter corresponding bifurcated artery, the diameter of used branch's overlay film frame should be slightly bigger than interior branch's branch
The diameter of frame lower cylindrical structure division, the diameter of branch's overlay film frame are that interior branch stent lower cylindrical structure division is straight
The 100~110% of diameter.
The invention has the benefit that can effectively solve to leak blood between aorta tectorial membrane stent and branch's overlay film frame bracket
Problem, the Structure adaptation major part vessel anatomy of interior branch stent is convenient to align with bifurcated artery blood vessel, and is not take up master
Vascular spaces do not influence the release of aorta tectorial membrane stent.
