Description
Technical field
The present invention relates to field of medical technology, specifically a kind of Artificial Intervention valve adaptation mounting ring.
Background technology
There are four valves in human heart, each valve is one " one-way cock ", control blood along certain direction
Flowing, and ensure to pass through certain flow.Human heart is damaged because of congenital not normal or posteriority lesion, thus develops implant
Enter valve replace lesion in human body heart be always medical field problem.The pure pyrolytic carbon bifolium of domestic production is artificial
Being implanted into valve includes valve frame, limb and annulus, and annulus serves as two effects, one is being connected with valve frame, secondly and human heart
Tissue apposition.
Artificial Intervention valve is widely used in openheart surgery, its in metal annulus outer wrapping fibr tissue suture ring, then
It is fixed to 10-20 pin interrupted sutures line above the fibrous tissue ring of human heart, it is necessary to cardiac arrest more than 30 minutes, and
It is also possible to occurring, because suture is not tight or the weak tear of tissue, causing the leakage blood (i.e. perivalvular leakage) of suture ring periphery, incidence is about
4% or so, now need to perform the operation or stop up a loophole using plugging device again.
The content of the invention
In order to solve the above technical problems, the present invention provides a kind of Artificial Intervention valve adaptation mounting ring, operation can be shortened
Time, the generation of perivalvular leakage event is reduced, it is safe and reliable.
A kind of Artificial Intervention valve is adapted to mounting ring, for assembling Artificial Intervention valve, Artificial Intervention valve include annulus,
Limb and valve frame, the Artificial Intervention valve adaptation mounting ring include the memory metal ring of amphidisc structure above and below compacting formation,
The middle part of memory metal ring forms perforate, and upper disk body, which stretches out, is interval with three lugs, and amphidisc is due to being compressed on up and down
Outside forms one and encloses water jacket, and inner side forms one and encloses inside groove, and Artificial Intervention valve can be stretched into and is caught in from the perforate of memory metal ring
In inside groove, water jacket is used to be caught in part human heart tissue, the upper disk body of memory metal ring and lower disk body when suturing to be set respectively
There is one layer of woven dacron.
The width of Artificial Intervention valve adaptation mounting ring as described above, water jacket and inside groove is about 3mm.
The present invention is by setting mounting ring to be amphidisc structure up and down, and the outer of part human heart tissue can be entered by being consequently formed
Groove and the inside groove for being caught in Artificial Intervention valve, so can be consolidated mounting ring and Artificial Intervention valve by simple three to four pin
Human heart tissue is scheduled on, Artificial Intervention valve is fixed to people body-centered with 10-20 pin interrupted suture lines compared with prior art
Above dirty fibrous tissue ring, operating time is shortened dramatically, and is respectively equipped with the upper disk body of memory metal ring and lower disk body
One layer of woven dacron, can effectively anti-Hemostatic Oral Liquid passed through from memory metal ring, effectively reduce the generation that blood phenomenon is leaked in suture ring periphery.

Embodiment
Below in conjunction with the accompanying drawing in the present invention, the technical scheme in the present invention is clearly and completely described.
Fig. 1 is refer to, the present invention provides a kind of Artificial Intervention valve adaptation mounting ring (abbreviation mounting ring) 1, and it includes note
Recall becket 11, memory metal ring 11 can be suppressed by nickel chromium triangle memorial alloy ring formed above and below amphidisc structure, middle part formed perforate
12, upper disk body, which stretches out, is interval with three lugs 13.Incorporated by reference to Fig. 2 and Fig. 3 is referred to, amphidisc is due to suppressing outside up and down
Side forms one and encloses water jacket 14, and inner side forms one and encloses inside groove 15, the width of water jacket 14 and inside groove 15 (above and below i.e. between amphidisc away from
From) it is about 3mm or so.One layer of woven dacron 6 is respectively equipped with the upper disk body of memory metal ring 11 and lower disk body, for anti-Hemostatic Oral Liquid
Passed through from memory metal ring 11.
Please also refer to Fig. 4 and Fig. 5, Artificial Intervention valve 2 includes annulus 21, limb 22 and valve frame 23.Sutured
During operation, Artificial Intervention valve 2 is put into from the perforate 12 of mounting ring 1 and is positioned in mounting ring 1 so that Artificial Intervention valve 2
Annulus 21 be caught in the inside groove 15 of mounting ring 1, the mounting ring 1 that then will be equipped with Artificial Intervention valve 2 is positioned over people to be performed the operation
At systemic heart tissue 3 and it is caught in part human heart tissue so that mounting ring 1 is placed in Artificial Intervention valve 2 and human heart group
Knit between 3.In suture, by being connected to the double-ended needle of suture 4, one of syringe needle is from the inner side of mounting ring 1, under
The supreme lower disk body for sequentially passing through mounting ring 1, the valve frame 23 for the Artificial Intervention valve 2 being placed in the inside groove 15 of mounting ring 1, mounting ring
1 upper disk body, another syringe needle sequentially passes through lower disk body, the people of mounting ring 1 from bottom to up from the outside of mounting ring 1
The upper disk body of systemic heart tissue 3, mounting ring 1, can be by mounting ring 1 and Artificial Intervention as described above by simple three pin
Valve 2 is fixed on human heart tissue 3, is compared with prior art fixed Artificial Intervention valve with 10-20 pin interrupted suture lines
To above the fibrous tissue ring of human heart, operating time is shortened dramatically, and the upper disk body of memory metal ring 11 and lower disk body
In be respectively equipped with one layer of woven dacron 6, can effectively anti-Hemostatic Oral Liquid passed through from memory metal ring 11, effectively reduce the leakage of suture ring periphery
The generation of blood phenomenon.
Aortic valve in normal film has three semicircle leaflets, and edge is curved to be attached on columnar aorta wall,
Therefore the structure of three triangles is left between three leaflets, three lugs 13 (ear is raised) that the present invention is designed are exactly
In order to adapt to this feature of aortic heart valve ring, three ear projections rise suitable between Artificial Intervention valve 2 and sustainer
The effect of orchestration, during implantation, three lugs 13 can play against three triangles between three leaflets on aorta wall and close this
The effect in three triangle spaces.
Disk below Artificial Intervention valve adaptation mounting ring of the present invention is together with special-shaped disk above, and folder closes human body master
Artery annulus (or pulmonary artery annulus), and Artificial Intervention valve 2 and human body master are closed by prominent lug 13 and circular edge
Gap between artery annulus (or pulmonary artery annulus), therefore, this adaptation mounting ring can reduce the generation of perivalvular leakage, play fixation
The effect of artificial valve, and pass through the use of this adaptation mounting ring, it is only necessary to three pins are fixed in suture, it is possible to when shortening operation
Between, operation wound is reduced, complication is reduced.
The foregoing is only a specific embodiment of the invention, but protection scope of the present invention is not limited thereto, any
Belong to those skilled in the art the invention discloses technical scope in, the change or replacement that can be readily occurred in, all should
It is included within the scope of the present invention.Therefore, protection scope of the present invention should be defined by scope of the claims.
