Description
Technical field
The present invention relates to field of medical technology, and in particular to a kind of valve cutting mold.
Background technique
In recent years, more and more children's aortic valve diseases need clinic to entangle to control, and become heart disease in children treatment concern
Hot spot.However it is different from adult, children's aortic valve disease often involves multiple leaflets, valve based on congenital dysplasia
Leaf disease complicates seriously, and individual difference is big.Therefore, it is big to repair difficulty for operation forming, then intervenes rate height, becomes heart disease in children and controls
One of the difficult point in treatment field, to pediatric cardiac surgery, doctor brings huge challenge.
The modus operandi of aortic valve disease includes aortic valvuloplasty and valve replacement at present.Single valve replacement
Simply, postoperative artificial valve function is good, is the most common modus operandi of adult aortic's valve lesion.However artificial valve cannot
Growth, mechanical prosthetic valve need anticoagulant throughout one's life, and bioprosthetic valves calcification decays rate height, it is clear that can't be the preferred art formula of child patient.From
The aorta petal (i.e. ROSS operation) of body pulmonary valve displacement lesion is considered as the recommendation hand of children's aortic valve disease treatment
Art avoids the generation of long-term anticoagulant therapy and calcification.However it needs to rebuild right ventricle using artificial valved external conduit in operation
Efferent tract is still suffered from because Outer Tube is decayed the problem of needing Repeated Operation to replace.There are new aorta petal roots for medium-long term simultaneously
Portion expands and the generation backflowed, and aortic root replacement and valve is needed the complicated operation such as to intervene again.It can be seen that ROSS
Operation is possible to " single valve lesion " being transformed into " double-valve diseases ".
Therefore, aortic valvuloplasty operation becomes the preferred modus operandi of children's aortic valve disease.Most common forming
Mode includes have a common boundary incision, leaflet extension, folding, suspention and puncture repair etc..These forming modes are mainly based upon original
It is repaired on the valve of lesion, the effect of forming is often depending on the degree of leaflet lesion, aorta petal list leaf disease become,
The treatment of simple lesion has preferable effect.Even if in this way, its 5 years re-treatm ent rate is still up to 10.
Kalangos and Myers was reported 77 in 2013 and is carried out actively because of rheumatic aortic valve disease using leaflet extension technology
Arteries and veins valve reparation, morning, late mortality each 1,5,10,15 years from being respectively 88.5%, 81.7%, 79.7% in operability.So
And it is complicated for lesion or involve multiple leaflet persons, above-mentioned recovery technique entangles that control effect undesirable, more than more than one third suffering from
10 years internal cause valves of person decay and need to perform the operation again.Miyamoto in 2016 etc. is to 34 because aorta petal Serious Stenosis receives valve
Otomy has carried out follow-up less than 3 monthly age infants, 5,10,15 years from intervening rate be again respectively 85.1%, 78.0%,
53.5%.There is western scholar to think, age of operation is small, bicuspid aortic valve may be risk factor that postoperative valve is decayed.
Vein graft aortic valvuloplasty is a kind of novel aorta petal recovery technique, is put forward for the first time, is answered by Duran etc.
It substitutes the aorta petal of lesion completely with Vein graft to rebuild to complete new aorta petal, the complexity suitable for being difficult to repair is main
Arterial valve lesion.By continuous technological improvement, Vein graft aortic valvuloplasty technology is controlled adult aortic's valve lesion
Good result is obtained in treatment.The application such as Ozaki technology treats adult aortic's valve lesion patient 788, including 534 narrow
With 254 incompetences, serious leaflet deformity includes 224 bicuspid aortic valves, 28 single leaf formula aorta petals, 2
Quadricuspid aortic valve.The follwing-up in average phase is 53.7 months, and postoperative across the valve pressure difference of 8 annual is 15.2mmHg, and only 4.2% suffers from
Person need to perform the operation again.Since postoperative low actual and low re-treatm ent rate, the operation gradually obtain the approval of various countries cardiac surgeon.
Reuthebuch etc. report 2015 to 2017 30, hospital, Univ Basel Switzerland (7 it is narrow, 12 backflow with 11 it is narrow
Narrow merging is backflowed) follow-up of the art formula, the death rate is 3.33% (n=1) in postoperative 30 days, without operator again in postoperative March.
Some cardiac surgeon of the country such as Germany, Spain also use the technology in clinic and carry out aorta petal reparation, early stage
Follow-up results are good.
However Vein graft aortic valvuloplasty technology application example in children's case is still few, lacks experience.Our hospital exists
It is improved and has been innovated in Ozaki operation, take the lead in using the technology in clinic to children's aorta petal serious change or tired out
And more leaflet persons carry out three valve reparation of leaflet, early postoperation follow-up shows good surgical outcome.But operation is complicated, needs
It takes a substantial amount of time to measure the height and width that cut valve.Due to children's aorta petal developmental deformity, often exist
Single leaf formula, bilobal or quaterfoil deformity, though in cloverleaf aorta petal, three leaflets have a common boundary be also it is unequal,
These need to relocate sewing site, determine sewing height, generally require to correct repeatedly, extend operating time.
In conclusion the present invention devises a kind of valve cutting mold.
Summary of the invention
In view of the shortcomings of the prior art, structure is set object of the present invention is to be to provide a kind of valve cutting mold
Meter rationally, valve size corresponding to different aorta petal diameters and sewing site is fixed in this mold, can be standardized
