Description
Technical field
This utility model relates to technical field of medical instruments, particularly relates to a kind of Novel artificial biological heart valve.
Background technology
Valve is equivalent to entrance guard, stops blood backflow in the ventricle just left, and valve, as the biological valve making blood form directed flow, makes heart promote blood and forms circulation.Between atrium and ventricle, between ventricle and the blood vessel leaving ventricle, there is valve.
For the patient suffering from severe heart valve disease, carrying out Cardiac valve prosthesis replacement by surgical operation is unique effective treatment means.Cardiac valve prosthesis is divided into artificial mechanical heart valve and artificial biological heart valve, because it has excellent biocompatibility and center flow channels compared with mechanical valve prosthesis, is widely used in clinical.And make its long-term survival rate not be better than artificial biological heart valve due to related complications etc. such as artificial mechanical valve prosthesis's anticoagulants, and the research of bioprosthesis valve is constantly made progress, its durability is greatly improved, so that more and more doctor and patient select artificial biological heart valve.Current artificial biological heart valve is heterograft tissue valve, bovine pericardium valve and porcine aortic valve.
Artificial biological heart valve makes according to the structural principle of mankind semilunar valve, mainly there are valve bracket, valve seat, lobe leaf and coated cloth etc., valve seat is generally hard material and makes, and there is certain width, conveniently sew up valve seat and lobe leaf, both junction has the suture ring that coated cloth is made.Valve bracket be tinsel in medical implantable around city three circular arcs of 120 degree each other continuously, the connected mode of valve bracket joint is telescopic joint, but has certain thickness due to sleeve pipe, and causing when making lobe leaf can not full symmetric; And because the corner of valve bracket is relatively more sharp-pointed, easily touches ventricle wall, cause the problems such as ventricle wall damage.
Utility model content
This utility model provides a kind of Novel artificial biological heart valve, to solve the problem mentioned in above-mentioned prior art.
This utility model provides a kind of Novel artificial biological heart valve, comprise valve seat, valve bracket and be attached to three biological tissue's lobe leaves on valve bracket, described valve bracket is that B alloy wire turns to three continuously circular arcs of 120 degree each other, wherein joint adopts telescopic joint, described sleeve pipe skew is in the side of the joint projection of described valve bracket, the coated two-layer woven dacron in outside of described sleeve pipe and described valve bracket, is provided with flexible gasket between the described two-layer woven dacron of the corner of described valve bracket.
Novel artificial biological heart valve as above, wherein, the specification of described flexible gasket is long 9mm, the rectangle pad of wide 2.5mm, thick 1mm.
Novel artificial biological heart valve as above, wherein, described flexible gasket is length is 9mm, and diameter is the cylinder of 2mm.
Novel artificial biological heart valve as above, wherein, the inside cross-sectional shape of described sleeve pipe is hexagon.
The Novel artificial biological heart valve that this utility model provides, at the coated two-layer woven dacron in outside of described sleeve pipe and described valve bracket, and flexible gasket is provided with between the described two-layer woven dacron of the corner of described valve bracket, thus make corner's softness of valve bracket round and smooth, alleviate the damage to ventricle wall, adopt telescopic joint in the joint of valve bracket, and sleeve pipe skew is in the side of the joint projection of valve bracket, valve is made to have more stable hemodynamic performance, better fatigue resistance.
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 sleeve pipe of the Novel artificial biological heart valve that Fig. 1 provides for this utility model embodiment and the schematic diagram of valve bracket;
The sectional view being coated with the corner of woven dacron of the Novel artificial biological heart valve 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 sleeve pipe of the Novel artificial biological heart valve that Fig. 1 provides for this utility model embodiment and the schematic diagram of valve bracket; The sectional view being coated with the corner of woven dacron of the Novel artificial biological heart valve that Fig. 2 provides for this utility model embodiment.Simultaneously with reference to Fig. 1 and Fig. 2, the Novel artificial biological heart valve that the present embodiment provides, comprise valve seat, valve bracket 101 and the three biological tissue's lobe leaves be attached on valve bracket 101, described valve bracket 101 turns to three continuously circular arcs of 120 degree each other for B alloy wire, wherein joint adopts sleeve pipe 102 to connect, described sleeve pipe 102 offsets the side of the joint projection at described valve bracket 101, wherein, the coated two-layer woven dacron in outside of described sleeve pipe 102 and described valve bracket 101, flexible gasket 103 is provided with between the described two-layer woven dacron of the corner of described valve bracket 101.
It should be noted that, the material of sleeve pipe 102 is identical with the material of valve bracket 101, because sleeve pipe 102 has certain thickness, in order to ensure the measure-alike of three bulge-structures, ensure to there is symmetry, in the present embodiment when making lobe leaf simultaneously, the joint of valve bracket 101 offset by certain distance, wherein, the inside cross-sectional shape of described sleeve pipe 102 is hexagon, thus ensures the firmness that valve bracket 101 connects.
In practical application, the specification of described flexible gasket 103 is long 9mm, the rectangle pad of wide 2.5mm, thick 1mm; Or described flexible gasket 103 is length is 9mm, and diameter is the cylinder of 2mm.The present embodiment does not do concrete restriction to this.Wherein, flexible gasket 103 can be the ribbon of the softness be made up of polyester textile.
The Novel artificial biological heart valve that the present embodiment provides, at the coated two-layer woven dacron in outside of described sleeve pipe and described valve bracket, and flexible gasket is provided with between the described two-layer woven dacron of the corner of described valve bracket, thus make corner's softness of valve bracket round and smooth, alleviate the damage to ventricle wall, adopt telescopic joint in the joint of valve bracket, and sleeve pipe skew is in the side of the joint projection of valve bracket, valve is made to have more stable hemodynamic performance, better fatigue resistance.
Last it is noted that above each embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail this utility model with reference to foregoing embodiments, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein some or all of technical characteristic; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the scope of each embodiment technical scheme of this utility model.
