Utility model content
This utility model provides a kind of biological cardiac valves with integral type lobe leaf, to solve above-mentioned problems of the prior art.
This utility model provides a kind of biological cardiac valves with integral type lobe leaf, comprise lobe seat, lobe frame and lobe leaf, described lobe leaf is fixed between described lobe seat and described lobe frame, described lobe leaf is integral type lobe leaf, the middle body hollow of described integral type lobe leaf, described integral type lobe leaf has three hemp nettle lobes, between adjacent petal, part connects, the outer of each described petal and the mating shapes of described lobe seat and described lobe frame, and be conformably fixed between corresponding described lobe seat and described lobe frame, junction between described petal is fixed on the below at described lobe angle, the width of the junction between adjacent described petal is 3mm.
Have the biological cardiac valves of integral type lobe leaf as above, wherein, the hollow space of described integral type lobe leaf is triangle, and described three sides of a triangle are the free edge of institute's integral type lobe leaf.
Have the biological cardiac valves of integral type lobe leaf as above, wherein, the intersection between the outer of adjacent described petal is M shape.
The biological cardiac valves of what this utility model provided have integral type lobe leaf, in the course of the work, due to lobe leaf for integral type designs, its stress is more even, Stress Transfer is to elasticity lobe frame, stress can be cushioned further, reduce the risk of biovalve calcification, thus improve the durability of biological cardiac valves.
Accompanying drawing explanation
In order to be illustrated more clearly in this utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
The schematic diagram one with the biological cardiac valves of integral type lobe leaf that Fig. 1 provides for this utility model embodiment;
The schematic diagram two with the biological cardiac valves of integral type lobe leaf that Fig. 2 provides for this utility model embodiment.
Detailed description of the invention
For making the object of this utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in this utility model embodiment, technical scheme in this utility model embodiment is clearly and completely described, obviously, described embodiment is this utility model part embodiment, instead of whole embodiments.Based on the embodiment in this utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of this utility model protection.
The schematic diagram one with the biological cardiac valves of integral type lobe leaf that Fig. 1 provides for this utility model embodiment; The schematic diagram two with the biological cardiac valves of integral type lobe leaf that Fig. 2 provides for this utility model embodiment.Composition graphs 1 and Fig. 2, the biological cardiac valves of what the present embodiment provided have integral type lobe leaf, comprise lobe seat 101, lobe frame 102 and lobe leaf 103, described lobe leaf 103 is fixed between described lobe seat 101 and described lobe frame 102, described lobe leaf 103 is integral type lobe leaf 103, the middle body hollow of described integral type lobe leaf 103, described integral type lobe leaf 103 has three hemp nettle lobes, between adjacent petal, part connects, the outer of each described petal and the mating shapes of described lobe seat 101 and described lobe frame 102, and be conformably fixed between corresponding described lobe seat 101 and described lobe frame 102, junction between described petal is fixed on the below at described lobe angle 104, the width of the junction between adjacent described petal is 3mm.
Wherein, the hollow space of described integral type lobe leaf 103 is triangle, and described three sides of a triangle are the free edge 105 of institute's integral type lobe leaf 103; Intersection between the outer of adjacent described petal is M shape.
In practical application, the outside of lobe seat 101 and lobe frame 102 is coated with infantees respectively, lobe seat 101 for top be evenly distributed with three depression annulars, protruding platform is formed between two adjacent depressions, lobe frame 102 is by the support with three equally distributed depressions of tinsel around city, the lobe angle 104 that formation three is protruding between the adjacent depression of lobe frame 102.In the use procedure of biological cardiac valves, the three sides of a triangle of the hollow space of integral type lobe leaf 103 are the free edge 105 of integral type lobe leaf 103, can swing between two lobe angles 104.When three free edges 105 are separated, biological cardiac valves is opening, passes through for blood; When three free edges 105 combine, biological cardiac valves is closed condition, stops blood back flow.Thus realize integral type lobe leaf 103 along with the forward flow of blood and open, close along with the reverse flow of blood.
Further, the radian of the radian of outer of each petal in three hemp nettle lobes of integral type lobe leaf 103 and the recess of the recess of lobe seat 101 and lobe frame 102 matches, the outer of each petal all can be conformably fixed between corresponding lobe seat 101 and lobe frame 102, intersection between the outer of adjacent petal is M shape, and the width of junction between adjacent petal is 3mm, the junction between adjacent petal is fixed on the below at lobe angle 104.Periphery, the bottom stitching thread carrying lobe seat 101 is sewed with for biological cardiac valves being sewn to the structural suture ring of inside of human body.
The biological cardiac valves of what the present embodiment provided have integral type lobe leaf, comprise lobe seat, lobe frame and lobe leaf, described lobe leaf is fixed between described lobe seat and described lobe frame, described lobe leaf is integral type lobe leaf, the middle body hollow of described integral type lobe leaf, described integral type lobe leaf has three hemp nettle lobes, between adjacent petal, part connects, the outer of each described petal and the mating shapes of described lobe seat and described lobe frame, and be conformably fixed between corresponding described lobe seat and described lobe frame, junction between described petal is fixed on the below at described lobe angle, the width of the junction between adjacent described petal is 3mm.In the course of the work, due to lobe leaf for integral type designs, its stress is more even, and Stress Transfer, to elasticity lobe frame, can cushion stress further, reduces the risk of biovalve calcification, thus improves the durability of biological cardiac valves.
