Description
Technical field
The utility model relates to the field of medical instrument technology, more particularly, to the heart valve based on transesophageal echocardiography
Film forming ring.
Background technique
There are four types of valves for the heart of human body, once lesion occurs in valve, blood circulation of human body will be affected, or even can lead
Heart failure and body organ function venereal disease is caused to become.Common valve reparation angioplasty in treatment valve lesion, surgeon borrow at present
The impaired heart valve of body aid outer circulation reparation.In order to keep long-term therapeutic effect, after valve reparation plasty, often
An artificial valve forming ring is implanted into the natural annulus of human body.Artificial valve forming ring generally has three-decker, innermost layer
For metal or high molecular material supporter, middle layer is silica gel, and outermost layer is stitching floor, and wherein the supporter of innermost layer mainly rises
To the effect of effective moulding.
After forming ring is implanted into heart, during heart motion cycle, the shape of forming ring can be sent out with annulus size
It is raw to change, for hard ring, it is not susceptible to deformation, the area of valve mouth but can be due to the area of forming ring thereon is kept constant
It being kept constant, limits the movement of annulus, myocardial compliance is poor, it is unable to satisfy the variation demand of valve orifice area, thus
The own movement of annulus is influenced, and then influences left heart function.Flexi-ring mostly uses greatly high molecular polymer as supporter, flexi-ring
It can deform in systole, not influence the movement of annulus, but flexi-ring is excessively soft, be unable to satisfy annulus and effectively mould
The requirement of shape.
Ideal forming ring is can to effectively adapt to the complicated fortune of cardiac cycle while providing preferable support strength
It is dynamic.
Utility model content
The purpose of the utility model is to provide the valvuloplasty rings based on transesophageal echocardiography, existing to solve
There is above-mentioned technical problem present in technology.
In order to achieve the above object, the utility model provides the following technical solutions:
Valvuloplasty ring based on transesophageal echocardiography, including support inner core, be coated on the support inner core
On silica gel middle layer, and the suture outer layer being coated in the silica gel middle layer, the support inner core includes being intervally arranged to set
The straightway and thread segment set, and two ends of the support inner core are straightway.
Further, the length of the straightway of two ends of the support inner core is the length of the thread segment nature
3 times of degree, the length of the straightway of middle section are 2 times of the length of the thread segment nature.
In a preferred embodiment, the support inner core uses titanium alloy integral molding.
In a preferred embodiment, the material of the suture outer layer is biocompatibility flannelette.
In a preferred embodiment, the support inner core is solid construction.
The valvuloplasty ring based on transesophageal echocardiography of the utility model, the support inner core of the forming ring by
Straightway and thread segment are intervally arranged molding, and the quantity of straightway and length are all larger than thread segment, are being implanted into the forming ring
After human heart, along with the stretching and compression of thread segment, make to be shaped to change with the movement of heart, the forming
The valve orifice area that ring limits can also change with heart movement, to adapt to the free movement rule of annulus, to drop
Influence of the low forming ring to left heart function.The forming ring of the utility model, can be effective while providing preferable support strength
The compound movement of ground adaptation cardiac cycle.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is the valvuloplasty ring structure schematic diagram based on transesophageal echocardiography of the utility model；
Fig. 2 is the structure of the support inner core of the valvuloplasty ring based on transesophageal echocardiography of the utility model
Schematic diagram.
Specific embodiment
Below in conjunction with the attached drawing of the utility model, the technical solution of the utility model is clearly and completely described,
Obviously, the described embodiments are only a part of the embodiments of the utility model, instead of all the embodiments.It is practical based on this
Embodiment in novel, every other reality obtained by those of ordinary skill in the art without making creative efforts
Example is applied, is fallen within the protection scope of the utility model.
According to Fig. 1-2, illustrate the valvuloplasty ring based on transesophageal echocardiography of the utility model, wraps
Include support inner core 1, the silica gel middle layer 2 being coated on above-mentioned support inner core 1, and the seam being coated in above-mentioned silica gel middle layer 2
Close outer layer 3, straightway 101 and thread segment 102 of the above-mentioned support inner core 1 including the setting that is intervally arranged, and above-mentioned support inner core 1
Two ends are straightway 101.The above-mentioned setting of the utility model, sets support plate inner core 1 in the straight line being intervally arranged
Section 101 and thread segment 102, thread segment 102 can make forming ring comply with movement of the natural valve annulus sphincter in cardiac cycle,
So that the perimeter of forming ring changes, to change the area of valve mouth defined by forming ring, meet normal physiological status,
To reduce influence of the forming ring to left heart function.Meanwhile straightway 101 provides preferable support strength, to lesion annulus into
The effective remodeling of row, stablizes annulus structure, eliminates the risk of recurrence deformation, reaches preferable long-term effect, and support inner core 1
The suture outer layer of outer package, the utility model are preferably biocompatibility flannelette, in order to the suture with heart, are conducive to subtract
The rupture of blood platelet and cell caused by blood eddy generation, prevents the generation of haemolysis when few valve-open or closing.
In addition, the length of the straightway 101 of two ends of above-mentioned support inner core 1 is above-mentioned 102 nature of thread segment
3 times of length, the length of the straightway 101 of middle section is 2 times of the length of above-mentioned 102 nature of thread segment, meanwhile,
Two ends of inner core 1 will be supported to be disposed as straightway 101, one is easy in the course of surgery to the behaviour of forming ring end
Make, the size of forming ring be conveniently adjusted, second is that the quantity of entire straightway 101 and length is made to be all larger than thread segment 102, it is therefore an objective to
So that entire forming ring is guaranteed enough support strengths, meets the requirement of the effective moulding of annulus.
Above-mentioned support inner core 1 is arranged using titanium alloy integral molding.Support inner core 1 can be by stainless steel, nickel cobalt (alloy), titanium
The materials such as alloy and Nitinol are made.It is preferably titanium alloy that inner core 1 is supported in the present embodiment.
Supporting inner core 1 can be hollow or part hollow structure, and it is solid that the utility model, which is preferably above-mentioned straightway 101,
Structure, since the support inner core 1 of the utility model has thread segment 102, in order to guarantee the support strength of forming ring, directly
Line segment 101 need to use solid construction.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
In this, anyone skilled in the art within the technical scope disclosed by the utility model, can readily occur in variation
Or replacement, it should be covered within the scope of the utility model.Therefore, the protection scope of the utility model is answered described with power
