Description

The adaptive installing ring of Artificial Intervention valve

Technical field

The present invention relates to field of medical technology, specifically the adaptive installing ring of a kind of Artificial Intervention valve.

Background technology

Have four valves in human heart, each valve is one " one-way cock ", controls blood along the flowing of certain direction, and ensures by certain flow.Human heart is because of congenital not normal or posteriority pathological changes damage, and the heart thus developing pathological changes in Artificial Intervention valve replacement human body is the problem of medical circle always.The pure pyrolytic carbon bifolium Artificial Intervention valve of domestic production comprises lobe frame, limb and lobe ring, and lobe ring serves as two effects, and the first is connected with lobe frame, its two with human heart tissue apposition.

Artificial Intervention valve is widely used in operation on heart, it is at metal lobe ring outer wrapping fibrous tissue suture ring, be fixed to above the fibrous tissue ring of human heart with 10-20 pin interrupted suture line again, need cardiac arrest more than 30 minutes, but also likely occur because sewing up not tight or organizing weakness to tear, cause the leakage blood (i.e. perivalvular leakage) of suture ring periphery, incidence rate, about about 4%, now needs again to perform the operation or use stopper to stop up a loophole.

Summary of the invention

For solving the problems of the technologies described above, the invention provides the adaptive installing ring of a kind of Artificial Intervention valve, can operating time be shortened, reduce the generation of perivalvular leakage event, safe and reliable.

The adaptive installing ring of a kind of Artificial Intervention valve, for assembling Artificial Intervention valve, Artificial Intervention valve comprises lobe ring, limb and lobe frame, the adaptive installing ring of described Artificial Intervention valve comprises the memory metal ring that compacting forms upper and lower amphidisc structure, the middle part of memory metal ring forms perforate, upper disk body stretches out and is interval with three lugs, upper and lower amphidisc forms a circle water jacket owing to being compressed on outside, inner side forms a circle inside groove, Artificial Intervention valve can stretch into from the perforate of memory metal ring and snap in inside groove, part human heart tissue is snapped in when water jacket is for sewing up, one deck woven dacron is respectively equipped with in the upper disk body of memory metal ring and lower disk body.

The adaptive installing ring of Artificial Intervention valve as above, the width of water jacket and inside groove is about 3mm.

The present invention is upper and lower amphidisc structure by arranging installing ring, formed thus can enter the water jacket of groups of people's systemic heart tissue and snap in the inside groove of Artificial Intervention valve, installing ring and Artificial Intervention valve can be fixed on human heart tissue by simple three to four pins like this, above the fibrous tissue ring with 10-20 pin interrupted suture line Artificial Intervention valve being fixed to human heart compared to existing technology, operating time shortens dramatically, and be respectively equipped with one deck woven dacron in the upper disk body of memory metal ring and lower disk body, can pass from memory metal ring by effectively anti-Hemostatic Oral Liquid, the generation of blood phenomenon is leaked in effective minimizing suture ring periphery.

Detailed description of the invention

Below in conjunction with the accompanying drawing in the present invention, the technical scheme in the present invention is clearly and completely described.

Please refer to Fig. 1, the invention provides the adaptive installing ring (abbreviation installing ring) 1 of a kind of Artificial Intervention valve, it comprises memory metal ring 11, memory metal ring 11 can be suppressed by nickel chromium triangle memorial alloy ring and form upper and lower amphidisc structure, middle part forms perforate 12, and upper disk body stretches out and is interval with three lugs 13.Incorporated by reference to reference to figure 2 and Fig. 3, upper and lower amphidisc forms a circle water jacket 14 owing to being compressed on outside, and inner side forms a circle inside groove 15, and the width (distance namely between upper and lower amphidisc) of water jacket 14 and inside groove 15 is about about 3mm.Be respectively equipped with one deck woven dacron 6 in the upper disk body of memory metal ring 11 and lower disk body, pass from memory metal ring 11 for anti-Hemostatic Oral Liquid.

Please also refer to Fig. 4 and Fig. 5, Artificial Intervention valve 2 comprises lobe ring 21, limb 22 and lobe frame 23.When carrying out sew application, Artificial Intervention valve 2 is put into from the perforate 12 of installing ring 1 and is positioned over installing ring 1, the lobe ring 21 of Artificial Intervention valve 2 is made to snap in the inside groove 15 of installing ring 1, then the installing ring 1 that Artificial Intervention valve 2 is housed is positioned over human heart to be performed the operation organize 3 places and snap in part human heart tissue, installing ring 1 is placed between Artificial Intervention valve 2 and human heart tissue 3.When sewing up, by being connected to the double needle of stitching thread 4, one of them syringe needle is from the inner side of installing ring 1, from bottom to up successively through the lower disk body of installing ring 1, be placed in the lobe frame 23 of the Artificial Intervention valve 2 of installing ring 1 inside groove 15, the upper disk body of installing ring 1, another one syringe needle is from the outside of installing ring 1, from bottom to up successively through the lower disk body of installing ring 1, human heart tissue 3, the upper disk body of installing ring 1, can installing ring 1 and Artificial Intervention valve 2 be fixed on human heart tissue 3 described above by simple three pins, above the fibrous tissue ring with 10-20 pin interrupted suture line Artificial Intervention valve being fixed to human heart compared to existing technology, operating time shortens dramatically, and be respectively equipped with one deck woven dacron 6 in the upper disk body of memory metal ring 11 and lower disk body, can pass from memory metal ring 11 by effectively anti-Hemostatic Oral Liquid, the generation of blood phenomenon is leaked in effective minimizing suture ring periphery.

Aortic valve in normal film has three semicircle lobe leaves, edge is curved to be attached on columnar aorta wall, therefore three leg-of-mutton structures are just left between three lobe leaves, three lugs 13 (ear is protruding) of the present invention's design, exactly in order to adapt to this feature of aortic heart valve ring, three ear projections play adapter between Artificial Intervention valve 2 and aorta, during implantation, three lugs 13, facing to three triangles between three lobe leaves on aorta wall, can play the effect in these three triangle spaces closed.

Disk below the adaptive installing ring of Artificial Intervention valve of the present invention is together with special-shaped disk above, folder closes human aortic lobe ring (or valve of pulmonary trunk ring), and close the gap between Artificial Intervention valve 2 and human aortic lobe ring (or valve of pulmonary trunk ring) by outstanding lug 13 and circular edge, therefore, this adaptive installing ring can reduce the generation of perivalvular leakage, play the effect of fixing artificial valve, and pass through the use of this adaptive installing ring, stitching is only needed to fix three pins, just operating time can be shortened, reduce operation wound, reduce complication.

The above; be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, anyly belongs to those skilled in the art in the technical scope that the present invention discloses; the change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claim.
