Technical field
The utility model relates to the field of medical instrument technology, specifically, being a kind of fixation device of Therapy of Left Ventricular Aneurysm.
Background technique
After myocardial infarction, downright bad cardiac muscle is gradually substituted by fibrous scar tissue, and locular wall is thinning, outside bulging, is formed
Aneurysm increases bulk of left ventricle, aggravates the preload of left ventricle, lead to cardiac insufficiency.Aneurysm is most commonly in left ventricle.It is interior
Section's drug therapy and surgery left ventricular volume reduction are clinically used treatment methods.Surgery left ventricular volume reduction is curative for effect, but
Operating difficulty is big, risk is high, and perform the operation case fatality rate and complication rate are high, and to the more demanding of patient, clinical application by
Limit；And medical curative effect is not good enough.
Surgery ventricular aneurysmectomy or surgery aneurysm fundoplication at present need mid-sternal incision, cut breastbone, and
The complex operations such as extracorporal circulatory system are needed, patient restores slow, and risk is big, and intervention aneurysm fundoplication can generate bulk of left ventricle
It reduces, cardiac output is caused to reduce, damage heart function.
Interventional therapy method:
1, parachute technology: may cause cardiac rupture, and aneurysm blocks not exclusively, malignant arrhythmia and cardiogenic sudden
It waits indefinitely, clinical use is stopped at by U.S. FDA in 2017.
2, minimally invasive joint intervenes left ventricle Reconstruction --- left room fundoplication: at present in clinical experimental stage, but can subtract
Few bulk of left ventricle makes it below normal value, and cardiac ejection amount is reduced, and heart function cannot effectively improve.

Technical problem:
The utility model and above-mentioned 2 kinds of therapeutic modalities are entirely different, by the minimally invasive method intervened of combining by the room of bulging
Wall tumor is fixed, and in ventricular systole not bulging, is reduced bulk of left ventricle but is not less than normal value, increase left room output quantity, improve the heart
Dirty Ejection function.
Summary of the invention
The purpose of this utility model is to provide a kind of fixation device of Therapy of Left Ventricular Aneurysm.
To achieve the above object, the technical solution adopted by the present invention is that:
A kind of fixation device of Therapy of Left Ventricular Aneurysm, the fixation device of the Therapy of Left Ventricular Aneurysm include skeleton (1) and film
(2)；The skeleton (1) is in integrally umbrella frame shape, and the skeleton (1) is by 6 nitinol alloy wires (3) and 1 steel cap (4) group
At；One end of 6 nitinol alloy wires (3) cover be fixed in steel cap (4), the other end is inclined outwardly 30 ° of formation tips
(5)；The film (2) is integrally in umbrella cover shape, and the film (2) covering is stitched on skeleton (1).
The material of the skeleton (1) is Nitinol.
The material of the film (2) is PTFE.
Described tip (5) a length of 0.5cm.
Described nitinol alloy wire (3) the curved radian can arbitrarily be set.
The utility model advantage is:
1, the fixation device of the Therapy of Left Ventricular Aneurysm of the utility model has wound small relative to current treatment method, extensive
It is multiple fast, since aneurysm is fixed, reduce the left ventricular volume of increase, protection directly is generated to heart function, improves heart function.
2, the fixation device of the Therapy of Left Ventricular Aneurysm of the utility model, by the minimally invasive method intervened of combining by the locular wall of bulging
Tumor is fixed, and in ventricular systole not bulging, is reduced bulk of left ventricle but is not less than normal value, increase left room output quantity, improve heart
Ejection function.
