Description
Technical field
The invention belongs to the field of medical instrument technology, refer in particular to a kind of for replacing the Advancement of Cardiac Valve Surgery of diseased heart valve
The utensil of operation is more specifically to provide a kind of for replacing two leaf bioprosthetic valves of human heart valvular function.
Background technique
In vertebrate, heart is hollow muscular organ, and there are four pump chambers for tool：Left atrium and left and right ventricles, often
A chamber has the one-way valve of its own.Synchronization pump action at left and right sides of heart forms cardiac cycle.The period originates in
Ventricular diastole is known as ventricular diastole.The motive power of promotion blood of human body flowing systemic circulation is the convergent force of ventricular muscles, blood
Stream from ventricle jet stream to venous return to the one-way flow in atrium when valve opening and closing activity realize.Ventricular contraction is kinetic pump,
Valve is valve, limit blood flow one-way circulation, once valve disorder, cannot complete opening and closing function, i.e., to carry out repair with
Replacement.
In department of cardiac surgery, manually the valve of heart valve replacement lesion, starts from generation nineteen sixty, has more than 50 years so far,
There are artificial bio-prosthetic valve and Mechanical Valve Prosthesis two types.Mechanical prosthetic valve is divided to again single flap and two flaps, and single flap is non-central because of its
Blood flow and excessive blood event have almost been abandoned in clinic.But mechanical prosthetic valve needs lifelong anticoagulant to take, valve noise
It influences, the card valve etc. that artificial valve inflammatoryization occurs is still a still scabrous problem.
Today after clinical application 50 years, traditional double leaf mechanical prosthetic valve are designed as cylindrical type, still, in use, still
There is many defects：
1. the joint slot of flap is each provided in circle wall so that bilobed flap it is cylindric it is interior close activity, leaflet joint and
The shearing force that leaflet activity generates damages blood constituent, is easy to cause the events such as blood thrombus, bleeding；
2. cylindrical outer shape and the appearance difference of tricuspid valve approximate ellipsoidal are more obvious, have to the dissection reconstruct of tricuspid valve
Greatly deformation obstructive action；
3. the effective area of columned design limitation valve mouth, causes negative obstacle, also have to myocardial systolic property negative
Influence；
4. having three beams blood flow point in the bivalve mechanical prosthetic valve in cylindrical type, there is energy consumption to increase negative effect blood flow.
Two leaf bioprosthetic valves of the applicant's design are provided because of it in annulus and the two flap places of joining while open and close
Maximized flap open area, can significantly decrease the generation of blood event, also there is simpler merging condition, and Opening Snap is reduced
Deng, overall structure novelty, function of the function closer to human heart leaflet.
Summary of the invention
The purpose of the present invention：It is movable in annulus that a kind of valves pieces such as simple two leaf of design are provided for Advancement of Cardiac Valve Surgery
With two leaves simultaneously open and close, can be reduced or without anticoagulation bioprosthetic valves of new generation, change its profile state completely.For the heart
Dirty surgical valve replacement art provides a kind of novel new bio valve for more meeting physiological requirement.
The invention is realized in this way：
A kind of two leaf bioprosthetic valves, setting include grommet, diaphragm A, diaphragm B, it is characterised in that：It is additionally provided with locating plate, diaphragm A
Lacing film and diaphragm B lacing film；The grommet is round or similar round；The diaphragm A and diaphragm B is respectively equipped with diaphragm point, film
Piece A and diaphragm B is simultaneously equipped with diaphragm A lacing film and diaphragm B lacing film, is sutured after the diaphragm point overlapping of diaphragm A and diaphragm B with fixing line,
Diaphragm A lacing film and diaphragm B lacing film and locating plate are equivalent, and locating plate is fixed on to the other end of grommet, two leaf of diaphragm A and diaphragm B
Valve constitutes two diaphragms handover mouth, diaphragm A arc opening, diaphragm B arc opening and the diaphragm A lacing film and diaphragm B of diaphragm A and diaphragm B
The handover mouth of lacing film.
Further, the area equation of the diaphragm A and diaphragm B.
Further, the overlapping widths of the equal length of the straight flange of the diaphragm A and diaphragm B, diaphragm A and diaphragm B are
0.2-0.4cm。
Further, the diaphragm A lacing film and diaphragm B lacing film and locating plate it is equivalent it is Chong Die after, with lacing film positioning linear slit
Positioning is closed, then the locating plate watchman's wooden clapper root suture of locating plate A is fixed on grommet with fixing line.
Further, the height of the locating plate is 1.8-2.0cm, and the height of locating plate A is with diaphragm A arc opening and film
Subject to piece B arc opening is Chong Die with grommet respectively, and the arc-shaped edges of diaphragm A arc opening and diaphragm B arc opening are no more than the ring of grommet
Top surface.
Further, the compound limit line of grommet setting 2-4 diaphragm A and diaphragm B.
Further, the shape of the arc-shaped edges of the arc-shaped edges and grommet of the diaphragm A arc opening and diaphragm B arc opening is protected
It holds consistent.
The advantages and positive effects of the present invention：
1) grommet of this two leaves bioprosthetic valves and annulus are elliptical shape, are set as two leaf diaphragms, are had closer to physiology, dissection
Area and center blood flow state significantly reduce blood damage, shrink myocardial relaxation closer to physiological status.
2) two leaf diaphragm areas of this two leaves bioprosthetic valves are equal, activity while under by the effect of same pressure, in valve
The open and close simultaneously of on the ring and two flap diaphragm places of joining, provides maximized flap open area, can significantly decrease blood thing
The generation of part, while the volume decline that two flaps can be made to generate, reduce noise.
3) design of this two leaves bioprosthetic valves is simple, and cost is lower, also has simpler merging condition, is conducive to heart valve
Dissection reconstruct, to protection human heart leaflet better adaptability, reduce metabolite stockpiling in leaflet, prevent leaflet
Calcification extends service life phase, use easy to spread.
