Think, therefore for the problems referred to above, it is proposed that a kind of Self-expandable encephalic artery holder device.
Utility model content
The purpose of this utility model is that provides a kind of Self-expandable encephalic artery to prop up rack-mounted to solve the problems referred to above
Put.
This utility model is achieved through the following technical solutions above-mentioned purpose, and this utility model provides a kind of self-inflated intracranial
Arterial bracket, including upper conduit, pouch, support, downcomer, the first drawn yarn, expanded film, the second drawn yarn and pouch mouth；Institute
State internal stent and be provided with the first drawn yarn and the second drawn yarn being connected with described first drawn yarn, and described first drawn yarn
And the junction between described second drawn yarn is provided with pouch, described first drawn yarn, the second drawn yarn and described pouch
Between form square structure, and the foursquare expanded film that is internally provided with, the two ends of described pouch be provided with upper conduit and under
Conduit, the cross section of described support is circular configuration, and the two ends diameter of described support is less than the diameter of described mid-stent, described
The surface configuration of pouch is truncated cone-shaped structure after having pouch mouth, and the expansion of described pouch.
Preferably, described upper conduit is funnel-shaped structure with the inside of described downcomer, and the diameter of described upper conduit is big
Diameter in described downcomer.
Preferably, it is helix structure between described first drawn yarn and described second drawn yarn.
Preferably, described pouch mouth is circular configuration, and described pouch mouth caves in pouch inside line.
The beneficial effects of the utility model are: entocranial artery can be helped to carry out suitable expansion, help the circulation of blood,
Stable connection between each the first drawn yarn and second drawn yarn, upper conduit and downcomer have certain buffering velocity of blood flow
Effect, expanded film can expand in certain scope.

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Refer to Fig. 1-4, a kind of Self-expandable encephalic artery support, including upper conduit 1, pouch 2, support 3, downcomer 4, the
One drawn yarn 5, expanded film the 6, second drawn yarn 7 and pouch mouth 21；Described support 3 be internally provided with the first drawn yarn 5 and with institute
State the second drawn yarn 7 that the first drawn yarn 5 connects, and the junction between described first drawn yarn 5 and described second drawn yarn 7
It is provided with pouch 2, between described first drawn yarn the 5, second drawn yarn 5 and described pouch 2, forms square structure, and square
Shape be internally provided with expanded film 6, the two ends of described pouch 2 are provided with upper conduit 1 and downcomer 4, and the cross section of described support 3 is
Circular configuration, and the two ends diameter of described support 3 is less than the diameter in the middle part of described support 3, the surface configuration of described pouch 2 has capsule
It is truncated cone-shaped structure after bag mouth 21, and described pouch 2 expansion.
As a kind of technical optimization scheme of the present utility model, described upper conduit 1 is funnel with the inside of described downcomer 4
Shape structure, and the diameter of described upper conduit 1 is more than the diameter of described downcomer 4, it is simple to the flowing of blood, facilitate pouch to expand.
As a kind of technical optimization scheme of the present utility model, between described first drawn yarn 5 and described second drawn yarn 7
For helix structure, easily stretch after expansion.
As a kind of technical optimization scheme of the present utility model, described pouch mouth 21 is circular configuration, and described pouch mouth
21 cave in pouch 2 inside line, it is possible to maximized carrying blood, help tremulous pulse to expand.
Arterial bracket in use, is implanted to the inside of blood vessel by this utility model, owing to blood is flowed into from upper conduit
The inside of support, the blood being flowed within pouch can be stored by the pouch of internal stent so that pouch expands, pouch
Expansion can cause volume to increase so that support volume becomes big slowly, and the first drawn yarn and the second drawn yarn are along with support volume
Change big, and be stretched, play the effect supporting ductus arteriosus wall.
The beneficial effects of the utility model are: entocranial artery can be helped to carry out suitable expansion, help the circulation of blood,
Stable connection between each the first drawn yarn and second drawn yarn, upper conduit and downcomer have certain buffering velocity of blood flow
Effect, expanded film can expand in certain scope.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, it is possible to realize this practicality in other specific forms new
