Description

Cardiac valve prosthesis and valve bracket thereof
Technical field
The present invention relates to medical instruments field, relate in particular to a kind of Cardiac valve prosthesis and valve bracket thereof.
Background technology
The cause of disease of valvular heart disease can be divided into congenital and two types of posteriorities.Congenital valvular heart disease is because valve dysplasia of when birth or hypoplasia.For example, aortic valve two lobeizations deformity can cause aortic stenosis or incompetence.If aortic stenosis or incompetence will seriously influence hemodynamics and change, cause the decline of carrying out property valvular function, cause heart failure at last, death.The roughly cause of disease of posteriority valvular heart disease can be divided into infection, degeneration, the change of rheumatism immunity or other reasons.Infection is that antibacterial passes through blood arrival heart inside and invades valve; Degeneration is that valve can be degenerated gradually, and is the most common with aortic valve along with the age is gradually long; The rheumatism immunity changes and mainly to refer to rheumatic heart disease, owing to streptococcal infection, causes immunoreation then and destroys cardiac valve.Other reason can comprise wound, the spontaneous fracture of chordae tendineae etc.The surgical operation therapy of treatment valvular heart disease mainly divides two kinds at present: a kind of is valvoplasty, promptly the valve of infringement is repaired; Another kind is a prosthetic valve replacement, promptly carries out the valve replacement with Cardiac valve prosthesis.
General prosthetic valve replacement all is to carry out through surgical operation.Though wound is bigger, operation is ripe, and success rate of operation is high, and complication rate is low.Cardiac valve prosthesis is categorized as two kinds at present, and a kind of is mechanical prosthetic valve, and a kind of is bioprosthetic valve.Bioprosthetic valve is far superior to mechanical prosthetic valve at aspects such as protection blood, the normal hemodynamics of maintenance; Bioprosthetic valve does not need lifelong oral anticoagulant, and mechanical prosthetic valve needs lifelong oral anticoagulant.Though bioprosthetic valve the persistency aspect be inferior to mechanical prosthetic valve, along with the progress of bioprosthetic valve design and lobe leaf anticalcium property process etc. techniques, the durability of bioprosthetic valve is progressively improve.Therefore, at present no matter the developing direction of valve is in the world or domestic all clear and definite, that is, the application of bioprosthetic valve will progressively replace mechanical prosthetic valve.
But there is following several respects problem in the existing manual biovalve orthopaedic surgical operations operating substitution process:
(1) size is not collapsible.Because all structures of all present bioprosthetic valve lobes are the rigidity structure, and artificial valve's model is limited, can't satisfy the valve demand of all ages and classes section, different weight and different lesions form fully.Under situation about can't mate fully, the doctor usually selects the artificial valve who is slightly less than lobe week for use, and its problem of bringing is, suture ligature is beaten easily and torn, and is fixing unstable, and nearly perivalvular leakage at a specified future date is generation easily also.If the model of selecting is excessive, then rigid snapping in caused tearing, damaging heart tissue easily.So in this case, must add and do lobe widening of the ring art, increase operation risk so undoubtedly.Particularly child or teenager because the lobe ring is little, are selected the bioprosthetic valve of ting model for use during operation; But growth along with age, body weight; The fixed valve of model can't further satisfy the hemodynamics demand, therefore need regularly carry out prosthetic valve replacement, to change bigger bioprosthetic valve; This has not only increased surgery cost, has also increased operation misery and operation risk;
(2) operation stitching difficulty.During the bioprosthetic valve displacement, valve is seamed to active position, needs 12～15 pins at least.Therefore, to how better, sew up quickly, reduce wound relevant and shortening cardiopulmonary bypass time etc. in the operation process, all have higher requirement with operation.Obviously, every many seam one pins all can increase operation risk.
And with respect to operating deficiency, the mode through intervene operation implanted prosthetic heart valve is little with its wound, obtain increasing concern to the invasive of human body is few.But so far, carry out valve replacement with the mode of Wicresoft's intervention apparatus and the problem that exists is more: (1) will be blocked the heart coronary artery opening if position, back, valve location is not good, cause acute myocardial infarction; (2) valve discharges the back if do not fix, and can directly come off, and slides into ascending aorta, causes ascending aorta and corresponding trunk bifurcated thereof to block.And the problems referred to above all might cause severe complications such as death, apoplexy, organ failure, and risk still is difficult to control, and risk can't remedy in case take place.

With reference to Fig. 5, Fig. 5 is the structural representation of artificial cardiac valve the 5th embodiment of the present invention.Be with the difference of the 3rd, the 4th embodiment: this sutural margin 43 is half worker's type sutural margin.This sutural margin 43 is provided with groove 432, and this groove 432 can be adaptive with the lobe ring.After heart is opened, with the excision of pathological changes valve, again Cardiac valve prosthesis is passed through groove 432 earlier; Be placed on the correct position of lobe ring; And this groove 432 also forms with the lobe ring and engage, and then groove 432 two sides and lobe circumferential weld are closed, at last with heart and thoracic cavity stitching.Because can forming with the lobe ring, the groove 432 of this sutural margin 43 engage, so, can reduce the sewing needle number, thereby reach the shortening operating time, the purpose of minimizing operation risk in that to carry out sutural margin 43 fashionable with the lobe circumferential weld.In addition, this sutural margin also has the characteristic of water-swellable, can fit tightly with tissue after the implantation.Perhaps this sutural margin also has the characteristic of climbing of valve bracket being covered gradually degraded with tissue.Therefore, the Cardiac valve prosthesis that has this half worker type sutural margin can also be used for the insertion type mode.For example, deliver to suitable position through conveyer device, sutural margin 43 water-swellables, thus groove 432 can snap in the human body valve wherein, and then expansible groove 432 can cooperate with the lobe ring position, makes between this Cardiac valve prosthesis and the lobe ring more firm.
Above-mentioned lobe leaf 20 is attached at the inner surface of valve bracket 10, and the two ends of lobe leaf 20 are fixed on the connecting portion 111.Lobe leaf 20 intersections are concave inward structure, so can reduce the amplitude of opening of lobe leaf 20, thereby reduce lobe leaf 20 stifled probabilities to arteria coronaria.As shown in Figure 6, the concave inward structure of lobe leaf 20 intersections makes the actual open scope of lobe leaf 20 be limited in the dotted line, reduced valve service time long after, lobe leaf 20 touches the probability of arteria coronaria.
Refer again to Fig. 1; The root of above-mentioned U-shaped opening 30 outwards extends and forms projection 31; This projection 31 can suitably strut the blood vessel of fitting with valve bracket 10; Increase the distance between arteria coronaria mouth and the lobe leaf 20, further reduce Cardiac valve prosthesis behind life-time service, block up the probability of arteria coronaria because of fatigue damage.And the bottom of U-shaped opening 30 is provided with the hollow out mouth 32 corresponding with the arteria coronaria mouth, thereby has guaranteed that blood flow is more smooth and easy, the generation of avoiding intermittent arteria coronaria to stop up.
In addition, the bottom of lower end 12 is inwardly drawn in and is inner buckle structure, thereby can avoid lower end compressing atrioventricular node, influences conductive cardiac tissue.
With reference to Fig. 7, Fig. 7 is the structural representation of artificial cardiac valve the 6th embodiment of the present invention.Be with the difference of first to the 5th embodiment: the outer wall of connecting portion 111 is provided with overlay film 112, and this overlay film 112 can prevent that the metal termination from contacting with blood vessel, thus thorn mill blood vessel.
With reference to Fig. 8, Fig. 8 is the structural representation of artificial cardiac valve the 7th embodiment of the present invention.Be with the difference of first to the 6th embodiment: the connecting portion 111 of upper end 11 upwards also is provided with extension 113, and this extension 113 better supplemental support makes this cardiac valve more stable at the ascending artery place, keep blood flow to; Whether and the axial length of valve bracket increases, and makes that in use discharging 2/3 valve bracket 10 back cardiac valve just starts working, operate the doctor this moment and can judge to regain according to cardiac valve working condition and position and reset.
To describe the process that Cardiac valve prosthesis of the present invention is placed through intervening mode below in detail.
Fixedly ear on valve bracket 10 connecting portions 111 (perhaps extension 112) is embedded in the locating slot of valve bracket fixing head outer wall (position of locating slot and shape are big or small to match with fixing ear); And then the sheath pipe is loaded in Cardiac valve prosthesis in the epitheca pipe in twitching.
Through conveyer device, get into through human body femoral artery otch, Cardiac valve prosthesis is sent to human aortic valve position.Discharge Cardiac valve prosthesis then, it is firm to make it the location.Sheath pipe far-end passes epitheca in the conveyer device; The relative motion of pipe and outer tube in the pulling epitheca just can be realized; When Cardiac valve prosthesis arrives the precalculated position, outer tube is drawn back certain distance, valve bracket 10 parts are exposed in the human body environment; And elder generation discharges 1/3 of valve bracket 10 length, then d/d part valve bracket 10 spreading under the body temperature effect.At this moment, can observe the effect in place of valve bracket 10 according to the situation behind the spreading.For example,, then can hold interior sheath, push away epitheca before the while, thereby drive the valve bracket fixing head if find that there is deviation the position.Because this moment, the fixedly ear of valve bracket 10 also was not released; It still is in the locating slot under the parcel of epitheca; The valve bracket fixing head just can spur fixedly that ear makes valve bracket 10 progress into epitheca, and under the extruding of epitheca inwall, valve bracket 10 can draw in until being got back to the state before discharging by the epitheca parcel fully gradually; Then reorientate again, discharge, until Cardiac valve prosthesis being fixed on best position.
