Description
Technical field
The present invention relates to medicine equipment heart valve repair techniques field, more particularly to a kind of accommodating intraocular bicuspid valve into
Shape ring.
Background technology
Plastic surgery for mitral valve is treatment mitral valve insufficiency Main Means, remains structure under mitral leaflet and valve,
The connection of chordae tendineae papillary muscle and left ventricle is remained, is conducive to diastole ventricle moulding, thus protect Assessment of Left Ventricular Systolic Function,
Operative mortality rate is low, and long-term effect is good.At present, mitral valvuloplasty annuloplasty surgery be carried out by large-scale open chest surgery, it is necessary to
Operated under cardiac arrest using cardiopulmonary bypass.
Plastic surgery for mitral valve treats mitral regurgitation heart valve disease by implantable artificial mitral valve forming ring.People
Work mitral valve forming ring is used as a part for plastic surgery for mitral valve with accessory heart septal defect (such as mitral valve insufficiency)
Correction.Bicuspid valve includes mitral annulus, leaflet, papillary muscle and chordae tendineae.Mitral regurgitation be when left ventricular contraction blood from
The backflow that left ventricle passes through bicuspid valve to atrium sinistrum.The expansion of mitral annulus can prevent the ability of valve, so as to cause valve
The distortion of mouth normal shape.
Artificial mitral valve forming ring is the important component of plastic surgery for mitral valve, is shaped using suitable artificial mitral valve
Ring is, it is necessary to right dimensions and shapes.It is the premise for making the good pairing of leaflet to recover the normal profile of mitral annulus.But it is right
In the selection of artificial mitral valve forming ring, personal experience and the hobby of doctor are heavily dependent at present.Patient inserted
Small artificial valve forming ring may bring mitral stenosis, and insert excessive artificial valve forming ring influence leaflet pairing
Height and area effect forming effect.
Need to be operated under cardiac arrest using cardiopulmonary bypass in traditional plastic surgery for mitral valve.Accurate measurement
Annulus of mitral valve size simultaneously judges that repairing effect is extremely difficult thing.In consideration of it, the present inventor applied on the 26th in September in 2016
No. 201610852365.6 patent of invention:Artificial mitral valve forming ring conveying device and artificial mitral valve forming ring delivery system
System, is improved by traditional mitral valve forming ring, is provided with artificial mitral valve valve forming ring adjustable
Section part, connects specific artificial mitral valve forming ring conveyer, can overcome the shortcoming of Traditional Man mitral valve forming ring.By
In artificial mitral valve forming ring conveying device, in art, doctor can carry out secondary tune to the artificial mitral valve forming ring being implanted into
Whole, adjustment mitral valve forming ring size and shape, the purpose of plastic surgery for mitral valve curative effect is improved to reach in time.The applicant exists
No. 201610850218.5 patent of invention filed in September in 2016 26 days：Artificial mitral valve forming ring, solves existing artificial two
Cusp forming ring implantation after, patient's postoperative recurrence need excessive risk secondary thoracotomy perform the operation be adjusted, and existing bicuspid valve into
Shape ring cannot repeatedly carry out the problem of size adjusting.
In view of the difficulty of processing of current mitral valve forming ring is higher, and it is complex using process, the applicant is devoted to
A kind of new accommodating intraocular mitral valve forming ring is developed, the difficulty of processing of mitral valve forming ring is further reduced, and cause
Mitral valve forming ring has more practical operation in use.
The content of the invention
The purpose of the present invention, exactly proposes that a kind of processing technology is relatively simple, the point of accommodating intraocular two of more practical operation
Valve forming ring.
