Description
Technical field
The present invention relates to medical equipment technical field, specifically, in being a kind of highly conforming properties sustainer art
Three branch stents.
Background technology
At present, when Stanford A types dissection of aorta or aortic aneurysm have influence on the arch of aorta, adopt merely
Inner cavity insulation effect is unable to reach with interventional technique.Open chest surgery is routinely used to such disease, in body
Full Aortic arch replacement is carried out under outer circulation, and three important branch of the arch of aorta are coincide one by one,
Simultaneously under direct-view in descending aorta be implanted into support, and by mount proximal end with displacement after the artificial blood of the arch of aorta
Pipe is coincide, and the operation needs to carry out under Deep Hypothermia Circulatory Arrest, operating time length, anastomosis of blood vessel be more,
Difficulty is high, wound is big, postoperative complications are more, and recovery is slow, successive treatment is costly.What is used at present does
Method is to sew three branches on straight tube support to simplify the purpose performed the operation to reach, but effect is unsatisfactory.
The shortcoming of prior art is：Because the arch of aorta is that height is drawn a bow, straight tube support poor compliance,
And the distance between the branch of arch of aorta individual difference is big, artificial branch is difficult matching；It is direct plus branch
It is sewn on the film of main support, lacks support, therefore branch is easy to be crushed or shifted, and causes blood flow not
Freely.
The content of the invention
In view of the shortcomings of the prior art, it is an object of the invention to provide three points in a kind of highly conforming properties sustainer art
Branch support, can very well fit with the arch of aorta, support is possessed higher compliance, also make support
Possesses preferable versatility.
To reach above-mentioned purpose, present invention is as follows：
Three branch stents in a kind of highly conforming properties sustainer art, including arch covered stnet and with arch covered stnet
Three branches being wholely set, the arch covered stnet includes support bottom, support bow portion and frame upper,
Three branches include branch one, branch two and branch three；
The degree of crook in the support bow portion is consistent with the structure of the arch of aorta, the branch one, the and of branch two
Branch three is separately positioned in support bow portion, positional structure and the master of the branch one, branch two and branch three
The three big branched structures that arch of aorta upper limb is sent are corresponded.
What is reached has the technical effect that：The structure that three branches are constituted with covered stnet and arch of aorta upper limb
The structure that three big branches are formed matches, and the support in surgical procedure in this programme can perfect and active
Arcus haemalis is fitted, and is simplified modus operandi, is greatly shortened the time of Deep Hypothermia Circulatory Arrest, solves three branches
Be difficult to identical problem, reduce the difficulty of operation, mitigate the wound of operation, make complication and the death rate big
Big reduction, and shorten the expense of length of stay and reduction operation.
Further, the support bow portion and frame upper are telescopic artificial blood vessel structure respectively,
The artificial blood vessel liner nitinol alloy wire is used as support frame.Be so designed that can cause three branches away from
Adjustable from distance, it is adaptable to a variety of anatomical structures, support bottom is the tubular structure that Polyester Fibers are made,
Also liner " Z " font nitinol alloy wire is used as support frame to the tubular structure.
Further, the distance between described branch one and branch three are 50~80 millimeters.
Further, the length of the branch one, branch two and branch three is respectively 20~30 millimeters.
It is preferred that, the skeleton of the arch covered stnet and three branch's connecting portions uses nitinol alloy wire one
It is body formed, support force can be improved, wherein nitinol alloy wire is arranged by " Z " font structure.
It is preferred that, the length of the support bottom is 140~180 millimeters, and its bore is 24~28 millimeters,
The bore of the frame upper is 28~32 millimeters.
The present invention remarkable result be：Had influence on actively in Stanford A types dissection of aorta or aortic aneurysm
During arcus haemalis, modus operandi can be simplified using the support, the time of Deep Hypothermia Circulatory Arrest is greatly shortened, reduced
Identical, the difficulty of reduction operation of three branches, mitigates the wound of operation, makes complication and the death rate significantly
Reduction, and shorten the expense of length of stay and reduction operation.
