Capable artificial blood vessel proximal end Four branches aortic graft and descending aorta bracket trunk is separation design, is needed in operation to two
Point carry out identical, and arch of aorta distal anastomosis position is deep, dissection complexity, it is very challenging, profound hypothermia can be extended and stop following
Ring time and operating time, influence blood coagulation system, are easy to damage recurrent nerve and oesophagus etc..
Utility model content
The purpose of this utility model is to provide a kind of total aortic arch replacement integration artificial blood vessels, can shorten operation
Time reduces the generation of complication.
To achieve the above object, it is artificial to provide a kind of total aortic arch replacement integration for the technical solution of the utility model
Blood vessel, including main pipeline, the main pipeline include first part, second part and be located at the first part and described second
Part III between part；
Branch artificial blood vessel and perfusion pipeline are provided in the first part；
It is provided with releasable first elastic metal rack on the inside of the second part, is set on the inside of the Part III
Be equipped with releasable second elastic metal rack, first elastic metal rack and second elastic metal rack by
Metal wire knitted forms, and the metal wire knitted density of second elastic metal rack is greater than first elastic metal rack
Metal wire knitted density.
Further, the enabling capabilities for the metal material that second elastic metal rack uses are greater than first elasticity
The enabling capabilities for the metal material that metallic support uses.
It further, further include snap ring structure, the snap ring structure is used for the Part III and the third portion
Exceptionally the human vas of side wraps up fastening.
Further, the snap ring structure includes soft band and for adjusting the elastic buckle of the soft band.
Further, the snap ring structure is made of degradable absorbing material.
Further, second elastic metal rack is made of degradable absorbing material.
Total aortic arch replacement integration artificial blood vessel provided by the utility model, when can be avoided dissection of aorta operation
Coincideing for distal end, simplifies operation, shortens surgical stapling and distal ischemia time, reduces difficulty of coincideing, and reduces complicated by postoperative
The generation of disease, meanwhile, by using degradable absorbing material, stress can be reduced and cause lasting inflammatory reaction, tissue edema,
The generation for reducing complication, is more favorable for the further genralrlization of the art formula.
Detailed description of the invention
Fig. 1 is a kind of signal for total aortic arch replacement integration artificial blood vessel that the utility model embodiment provides
Figure；
Fig. 2 is a kind of schematic diagram for snap ring structure that the utility model embodiment provides.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.
It is a kind of total aortic arch replacement integration artificial blood vessel that the utility model embodiment provides referring to Fig. 1, Fig. 1
Schematic diagram, total aortic arch replacement integration artificial blood vessel includes main pipeline 1, the main pipeline include first part 1a,
The second part 1b and Part III 1c between the first part 1a and the second part 1b；
Wherein, main pipeline 1 is integrated pipeline, such as can be a terylene pipeline；
Wherein, three branch artificial blood vessels 2 corresponding with head arm blood vessel and perfusion are provided on the first part 1a
Pipeline 3；
Releasable first elastic metal rack is provided on the inside of the second part 1b, the Part III 1c's is interior
Side is provided with releasable second elastic metal rack, first elastic metal rack and second elastic metal rack
It is formed by metal wire knitted, and the metal wire knitted density of second elastic metal rack is greater than first elastic metallic
The metal wire knitted density of bracket；
Drop is formed actively by second part 1b, Part III 1c, the first elastic metal rack, the second elastic metal rack
Pulsation frame trunk can open true chamber, close false chamber, interlayer is promoted to stablize, since main pipeline 1 is integrated pipeline, and due to
The metal wire knitted density of second elastic metal rack is greater than the metal wire knitted density of the first elastic metal rack, the second elasticity
Metallic support composition exempts from stapling apparatus, when the first elastic metal rack and the second elastic metal rack are released, compared to the
One elastic metal rack, the second elastic metal rack are capable of providing preferably from swollen performance, and Part III 1c is enable tightly to paste
It closes on the aorta wall of human body, prevents blood from overflowing, play " match result "；
Preferably, in order to further improve compactness, the first elastic metal rack is compared, the second elastic metal rack can
To use the better metal material of enabling capabilities, i.e. the enabling capabilities for the metal material that the second elastic metal rack uses are greater than the
The enabling capabilities for the metal material that one elastic metal rack uses, it is preferable that second elastic metal rack can use can
Degradation absorbing material is made, for example, the metal material that the second elastic metal rack uses can be magnesium base alloy material, the first bullet
The metal material that property metallic support uses can be Nitinol；
Preferably, in order to further strengthen the fitting effect between artificial blood vessel and aorta wall, the utility model is implemented
Total aortic arch replacement integration artificial blood vessel in mode further includes snap ring structure, and the snap ring structure is used for the third
