Description
Technical field
The present invention relates to technical field of medical instruments, more particularly to a kind of occluder for left auricle.
Background technology
Auricular fibrillation (atrial fibrillation) is that atrial fibrillation is sent out in clinically most common perpetual arrhythmia, general population
Sick rate is 0.5%~1.3%.The topmost harm of atrial fibrillation is easily caused after promoting thrombosis, thrombus breaks loose
The complication such as cerebral apoplexy, peripheral vascular embolism, dramatically increase disability rate and fatal rate.Cerebral apoplexy be atrial fibrillation most
There are about 15,000,000 people suffers from cerebral apoplexy every year in the common, complication that harm is maximum, world wide, wherein
20%~25% is attributed to atrial fibrillation.The cardiogenic thrombus of rheumatic heart disease patients with atrial fibrillation of studies have shown that 60% comes
From more than 90% thrombosis in left auricle of heart, Non-valvular disease patients with atrial fibrillation in left auricle of heart.Therefore, the left heart is intervened
Ear prevents patients with atrial fibrillation thromboembolism, especially palsy, with important theoretical foundation and clinical meaning.
Anticoagulant therapy is currently the standard method for preventing atrial fibrillation palsy complication, but anticoagulant therapy is present necessarily
Limitation.Therefore it is significant using more efficient safe measure prevention atrial fibrillation palsy.It is at present to use more
Utilize the method for the inaccessible left auricle of heart of interventional therapy.Conventional occluder for left auricle has with WATCHMAN
For plunger type plugging device in the monomer of representative and with plug that AMPLATZER Cardiac Plug (ACP) are representative
Disc type occluder for left auricle.
1st, the defect and deficiency of interior plunger type occluder for left auricle
Interior plunger type plugging device is the framework using Nitinol as self-expanding structure, around there is fixed barb, the heart
Room face is covered by polytetrafluoroethylstephanoporate stephanoporate permeable membrane, and blood flow can pass in and out left auricle of heart.
When the apparatus fills in left auricle of heart, due to left auricle of heart oral area shape very irregular, and the deformation of the apparatus
It is limited in one's ability, it is impossible to block left auricle of heart oral area completely, it is difficult to which that elimination causes left auricle of heart portion to be formed due to atrial fibrillation
Thrombus.The planform of left auricle of heart is different, varying depth, also multi-cavity structure, interior plunger type left atrial appendage occlusion
Device can not adapt to the anatomical structure of all left auricle of hearts completely, while stable fixation can not be realized.
2nd, the defect and deficiency of dish-type occluder for left auricle are filled in
Fill in dish-type plugging device be a kind of pair of dish sample left atrial appendage occlusion device, by be placed in left auricle of heart butterfly blade and
Butterfly cap is constituted, and is connected in the middle of the two by the waist being recessed, butterfly blade, which is placed in left auricle of heart, prevents plugging device from moving
Position, butterfly cap seals left auricle of heart oral area.
It is closure disk and fixed disk one to fill in disc type occluder for left auricle, it is impossible to completely independent deforms, works as plug
Son is filled in after left auricle of heart, when disc part is buckled in the oral area of left auricle of heart, can be pulled, make by plug portion
The oral area of left auricle of heart can not be fully fitted in by obtaining disc part, be extremely difficult to optimal plugging effect.Due to plug
The subdivision and length adjustment of disc part is limited is difficult to optimal fixation and bloodstream blocking, while disc knot
Structure is simultaneously not suitable with different left auricle of heart cavity shapes.
In a word, either interior plunger type or plug dish-type occluder for left auricle, for different, varying depth
Left auricle of heart, have certain defect and deficiency, it is therefore necessary in the further investigation of plugging device configuration aspects to solve
Defect present in prior art and weak point.
The content of the invention
It is an object of the invention to provide a kind of occluder for left auricle, to solve existing occluder for left auricle pair
The problem of the adaptability of different, varying depth left auricle of heart is not strong.
In order to solve the above technical problems, the present invention provides a kind of occluder for left auricle, the occluder for left auricle
Including plugging structure and fixed structure, the occluder for left auricle also includes：Detachable adjustment structure, institute
Stating detachable adjustment structure includes first component and can separate or close with the first component second
Part, the first component and the second component can do relative motion, the first component and the envelope
Bridging structure is connected, and the second component is connected with the fixed structure.

For screw nut structure, and the detachable adjustment structure in the present embodiment four is buckle structure.
Specifically, refer to Fig. 7, it is the structural representation of the detachable adjustment structure of the embodiment of the present invention four
Figure.As shown in fig. 7, detachable adjustment structure 42 includes first component 420 and can be with described first
The second component 421 that part 420 is separated or closed, first component 420 and the second component 421 energy
Enough do relative motion, the first component 420 is connected with the plugging structure, the second component 421 with
The fixed structure connection.Wherein, the first component 420 is card and/buckling parts, the second component 421
For fastening/Ka Hebu.
In the present embodiment four, left auricle of heart can be adjusted by the insertion depth between card and portion and buckling parts and sealed
Length/depth of stifled device, so as to adapt to different left auricle of heart depth.
Wherein, the connected mode between the detachable adjustment structure and Flexible Connector and fixed structure
Embodiment one is referred to, the present embodiment four is repeated no more to this.
