Description
Technical field
This utility model relates to medical instruments field, particularly relates to a kind of prosthetic heart valve holder and has this
The Cardiac valve prosthesis of artificial valve's support.
Background technology
Cardiac valve is grown between atrium and ventricle, between ventricle and large artery trunks, play the work of one-way cock
With, help blood flow unidirectional motion.Four valves of human body are called Bicuspid valve, Tricuspid valve, aorta
Lobe and valve of pulmonary trunk.These valves, in the event of pathological changes, will affect the motion of blood flow, thus cause the heart
Dirty dysfunction, ultimately results in heart failure.
The type of valve pathological changes is typically narrow or incompetence.The insufficient amplitude that narrow finger valve opens,
The blood causing entry into the next chambers of the heart reduces；It is not tight that incompetence refers to that valve closes, and causes part blood to return
Stream.Narrow and/or incompetence once occurs, normal blood will be hindered to flow, increase corresponding heart
Burden, thus cause heart normal function to damage, cause heart failure and the change of body multi viscera function.
At present the surgical operation therapy of valvular heart disease mainly divides two kinds of methods: 1) valvoplasty, i.e. to damage
The valve of evil places under repair；2) prosthetic valve replacement, is replaced by Mechanical Valve Prosthesis or bioprosthetic valve.
Valvoplasty is generally used for the slight Bicuspid valve of pathological changes or Tricuspid valve, and for serious cardiac valve
Pathological changes, particularly valvular heart disease, more options prosthetic valve replacement.The main method of valvoplasty
As KeyShi shaping, DeVega shape and utilize the modes such as C-shaped ring shaping.Prosthetic valve replacement system uses people
People's diseased heart valve is replaced, such as mechanical prosthetic valve, bioprosthetic valve etc. by work valve.The mechanical prosthetic valve life-span is long, but
Need to take medicine throughout one's life anticoagulant, easily produces complication, and bioprosthetic valve is not required to lifelong anticoagulant, and but the life-span is short.
In recent years, for mitral stenosis and reflux patient can also percutaneous through the mitral valve of sheath pipe
Replacement, i.e. carries out this operation by intervention, the method for Wicresoft, allows patient avoid the hardship of open chest surgery.
A human heart left side is felt concerned about system (as shown in Figure 1) and is included left atrium 9, left ventricle 1, is positioned at left atrium 9
And the annulus of mitral valve 6 between left ventricle 1, annulus of mitral valve 6 is positioned at the side of left ventricle 1 anterior mitral cusp
5 and PM leaflet 12, and connect Bicuspid valve and the chordae tendineae 8 of left ventricle 1.Of the prior art manually
Valve device includes the valve member within grid framework 7 and framework 7.Framework 7 includes shirt rim 10, framework
Main body 2, front leaflet anchor log 4 and posterior valve leaflet anchor log 3.Shirt rim 10 is positioned at the end of chassis body 2,
And extend towards the direction of the axis approximately perpendicular to chassis body 2 from this end, form flange.Framework master
The inside of body 2 is used for secure valve, and shirt rim 10 is fitted on annulus of mitral valve 6 for preventing the generation of perivalvular leakage,
Front leaflet anchor log 4 and posterior valve leaflet anchor log 3 are respectively used to fixing anterior mitral cusp 5 and Bicuspid valve back lobe
Leaf 12 prevents framework 7 to be shed to left atrium 9 under the impact of blood flow.
Before being individually fixed in Bicuspid valve due to front leaflet anchor log 4 of the prior art and posterior valve leaflet anchor log 3
Leaflet 5 and PM leaflet 12 are to prevent framework 7 to be shed to left atrium 9 under the impact of blood flow, and lobe
Leaf texture is more fragile, therefore, front leaflet anchor log 4 and posterior valve leaflet anchor log 3 not only easy damaged leaflet, and
Easily come off above leaflet, thus directly result in Cardiac valve prosthesis stability on heart valve tissue relatively
Difference, have impact on the service life of Cardiac valve prosthesis, adds the risk of patient's replacement valve again.
