1, the outer wall of the netted intravascular stent 1 is equipped with the plugging device for leak stopping, first air bag 7, the second air bag 8 and third
Air bag 9 is set on the charge and discharge tracheae 6, and the inflation pump 11 is connected with the charge and discharge tracheae 6, the charge and discharge tracheae 6
Be equipped with several control valves 12, the charge and discharge tracheae 6 by the control valve 12 respectively with first air bag 7, the second air bag 8
It is connected with third air bag 9, the controller 10 is used to control the inflation/deflation and the control valve 12 of the inflation pump 11
It opens and closes, the section of the first air bag 7 and third air bag 9 after inflation is trapezoidal, and the section of the second air bag 8 after inflation is in
Rectangle, the controller 10 are used to control the opening and closing of the inflation/deflation and the control valve 12 of the inflation pump 11, lead to
The unlatching that the controller 10 controls the control valve 12 respectively is crossed, and then to first air bag 7, the second air bag 8 and third
The inflation that air bag 9 is distinguished, different parts that in operation can according to actual needs to the netted intravascular stent 1
It is strutted accordingly, and by the structure of first air bag 7 and third air bag 9 after inflation, so that the netted blood
The both ends of pipe holder 1 can be easily formed bell-mouthed shape, and easy to operate, so that 1 energy of netted intravascular stent
Blood vessel is enough blocked, prevents netted intravascular stent 1 from shifting in the blood vessels, additionally makes the closure outside netted intravascular stent 1
Device is closer in conjunction with blood vessel, and the present apparatus is operationally also relatively simple, when completing the Process of Leaking Stoppage of blood vessel, only
It needs respectively to deflate first air bag 7, the second air bag 8 and third air bag 9, and the charge and discharge tracheae 6 is extracted out.
Specifically, several lateral through-holes 13 are equipped on first air bag 7, the second air bag 8, third air bag 9, due to
First air bag 7, the second air bag 8, third air bag 9 can block the inside of the netted intravascular stent 1 in inflation, to lead
Cause blood circulation unsmooth, and the through-hole 13 can be unsmooth to human body to avoid the blood circulation caused by carrying out during leak repairing
Caused by damage, improve the present apparatus use when safety.
Specifically, first air bag 7, the second air bag 8 and third air bag 9 are on the charge and discharge tracheae 6 according to the second gas
The sequence of capsule 8, third air bag 9 and the first air bag 7 arranges, and second air bag 8 is adjacent with the inflation pump 11, by described
The relationship of the arrangement position of first air bag 7, the second air bag 8 and third air bag 9, between first air bag 7 and third air bag 9
First air bag 7 is first inflated by the length that distance is equal to the netted intravascular stent 1 when carrying out practical operation, from
And one end of netted intravascular stent 1 far from the inflation pump 11 is propped up, thus by the netted intravascular stent 1 in blood
The position of leakage blood is blocked in pipe, is avoided netted intravascular stent 1 from sliding in the blood vessels, is then inflated the second air bag 8 by net
Shape intravascular stent 1 is whole to be strutted, and charge and discharge tracheae 6 described in pull, so that the first overlay film 2 and the separation of the second overlay film 3, thus
Make the exposure of tissue glue-line 5, the effect that struts due to the second air bag 8 to the netted intravascular stent 1, the tissue glue-line 5 can
It is closely pasted with blood vessel together, when first overlay film 2 and the second overlay film 3 are kept completely separate, 9 meeting of third air bag
It aligns with the other end of the netted intravascular stent 1, then the third air bag 9 is inflated, so that netted blood
The other end of pipe holder 1 is also softened, thus by the bell shape structure at netted 1 both ends of intravascular stent by the net
Shape intravascular stent 1 is effectively fixed.
Specifically, the plugging device includes around the first overlay film 2 and the second overlay film set on the netted intravascular stent 1
3, adhesion mechanism is equipped between first overlay film 2 and second overlay film 3, first overlay film 2 is set to second overlay film 3
Periphery and connect with 3 brittleness of the second overlay film, second overlay film 3 is connected with the outer wall of the netted intravascular stent 1,
The charge and discharge tracheae 6 is equipped with several flexible connection lines 4 for the first overlay film 2 described in pull, by first overlay film 2,
The cooperation of adhesion mechanism, second overlay film 3 and netted intravascular stent 1, will by the flexible connection line 4 of the charge and discharge tracheae 6
When first overlay film 2 is gradually detached with second overlay film 3 so that the adhesion mechanism be gradually exposed and and blood vessel by
It gradually bonds, and then will completely be blocked at leakage blood, so that bonding effect and plugging effect are more preferable, due to blood vessel meeting after blood loss
It is shunk, when restoring normal, blood vessel then will do it diastole, therefore can be avoided blood vessel by the present apparatus and restoring to original state
The situation that netted intravascular stent 1 caused by after state is subjected to displacement, and can be identical as diastole carry out with the contraction of blood vessel
Movement, improve the applicability of the present apparatus.
Specifically, the adhesion mechanism is the tissue glue-line 5 with mobility, blood is met due to tissue glue-line 5 and is then solidified,
In the case that first overlay film 2 is gradually detached with second overlay film 3, the tissue glue-line 5 can be along the first overlay film 2
It detaches direction gradually to solidify and be gradually bonded together with blood vessel, to improve the adhesiving effect of tissue glue-line 5.
Specifically, the section of first overlay film 2 is in concave shape, the section of second overlay film 3 is L-shaped, passes through
Cooperate between first overlay film 2 and the structure of the second overlay film 3, tissue glue-line 5 is effectively avoided to leak, the first overlay film 2 and described second
The cavity for holding the tissue glue-line 5, when applying certain pull dynamics, described first are formed by between overlay film 3
Overlay film 2 and the brittleness junction of second overlay film 3 will disconnect, and cover so that blood penetrates into the first overlay film 2 with described second
The position of 3 phase of film separation passes through 2 He of the first overlay film so that tissue glue-line 5 is gradually solidified and bonded with blood vessel
The cooperation of second overlay film 3 avoids the blood when being put into the present apparatus from directly contacting with tissue glue-line 5 and lead to tissue glue-line 5
It is solidified in the position far from leakage blood, to improve the reliability when present apparatus uses.
Specifically, the both ends of the netted intravascular stent 1 are in bell shape, pass through netted 1 both ends of intravascular stent
Bell shape the present apparatus is to a certain extent strutted blood vessel, avoid vessel diameter smaller and cause people
Body blood pressure is higher to be happened.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
