Description
Technical field
The present invention relates to the field of medical instrument technology, and in particular, to implantable atrium part flow arrangement.
Background technique
Heart failure (heart failure) abbreviation heart failure, refers to the contractile function and (or) diastolic function due to heart
Obstacle occurs, heart cannot be sufficiently discharged in venous return, lead to venous system sludging, arterial system hemoperfusion
Deficiency shows as pulmonary venous pleonaemia, vena cave extravasated blood so as to cause cardiac cycle obstacle syndrome in such obstacle disease cluster.The heart
Force failure is not an independent disease, but the terminal stage of heart disease development.Wherein most of heart failure
All it is to be started with left heart failure, that is, first appears as pulmonary circulatory stasis.
Atrium sinistrum continuous high-pressure makes left chamber compression increase filling volume, and stroke volume increases and leads to left ventricular hypertrophy, in turn
Lead to chronic heart failure.For duration atrium sinistrum high pressure patient, clinical research finds that artificial atrial septal defect can be effective
Atrium sinistrum high pressure is reduced, left atria volume is reduced, to alleviate left heart function sexual dysfunction.But the artificial room for puncturing manufacture
Every defect, there are the risks of secondary closure.
For this purpose, those skilled in the art are supported by using stoma portion in atrial septum for bracket, so that 78% patient
NYHA cardiac functional grading switchs to II grade by III grade.The Du Ke activity questionnaire index and Kansas cardiomyopathy questionnaire of all patients is commented
Point, it is significantly improved, gait test range averaging increases by 74 meters within 6 minutes.In addition, the pulmonary capillary wedge pressure of patient is also
Decline, average out to 23mmHg when baseline, 3 months whens, drop to 17mmHg (P=0.035).But in the long-term use,
The bracket of implantable is also easy to produce thrombus, so that health is further endangered, for this purpose, a recyclable atrium of research and development shunts dress
Setting is particularly important.
Summary of the invention
For in view of the above drawbacks of the prior art, the main purpose of the present invention is to provide implantable atrium part flow arrangement,
Realize the beneficial effect of convenient recycling.
In order to solve the above technical problems, the embodiment of the invention provides implantable atrium part flow arrangements, including, left disk, the right side

It is take-up beam that the take-up head of the braiding of the left disk, which is mixed into a branch of, and the take-up beam inserts in take-up ball；
The right disk and the left disk are sutured in waist disk two sides respectively；
Left disk connecting line is set on circumferencial direction at the maximum gauge of the left disk, and the end of a thread of the left disk connecting line is located at
The outer surface of take-up beam is simultaneously fixed in take-up ball；When the take-up ball is rotated relative to take-up beam, the left disk connecting line is twined
It is around in take-up beam surface, reduces the maximum gauge of the left disk.
Wherein, right disk connecting line, the line of the right disk connecting line are set on circumferencial direction at the maximum gauge of the right disk
Head is located at the outer surface of take-up beam and is fixed in take-up ball；When the take-up ball is rotated relative to take-up beam, the right disk connects
Wiring is wound in take-up beam surface, reduces the maximum gauge of the right disk.
Wherein, waist disk connecting line is set on the circumferencial direction of the waist disk, and the end of a thread of the waist disk connecting line is located at take-up
The outer surface of beam is simultaneously fixed in take-up ball；When the take-up ball is rotated relative to take-up beam, the waist disk connecting line is wound in
Take-up beam surface makes the diameter reduction of the waist disk.
Wherein, the maximum gauge of the left disk is 22-30mm.
Wherein, the maximum gauge of the left disk is greater than the maximum gauge of right disk.
Wherein, the waist disk inner surface seamed endless membrane material.
Wherein, the material of the annular membrane material is PET or ePTFE.
Wherein, the waist disk is equipped with radiography point.
In embodiments of the present invention, it is designed by novel structure, so that whole implantable atrium part flow arrangement can be at any time
Recycling, solves the irretrievable technical problem of existing implantable atrium part flow arrangement, extends the sufferer service life, and recycle more
It is convenient.
