Problems solved by technology
However, the operation is complicated and it takes a lot of time to measure the height and width of the cut valve
Due to the developmental malformation of the aortic valve in children, there are often unileaflet, bicuspid or quadrileaflet deformities. Even in the tricuspid aortic valve, the junction of the three leaflets is not equal, and these need to be repositioned. point, to determine the sewing height, it often needs to be corrected repeatedly, which prolongs the operation time

Embodiment Construction
[0014] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.
[0015] refer to figure 1 , the specific embodiment adopts the following technical solutions: valve cutting mold, including template 1, model mark 2, valve hole 3 and valve connection overlapping hole 4, template 1 is provided with multiple groups of valve holes 3 with different sizes, and valve holes 3 are two Two valve connection overlapping holes 4 are respectively provided at the two ends, and a model mark 2 is provided on the outside of the valve connection overlapping hole 4 on one side; the valve hole 3 is three equal and connected valve holes, each valve hole has a Mark point 5 for the lowest point.
[0016] The valve hole 3 is three connected U-shaped units.
[0017] When this specific embodiment is used, the patient's own pericardial ti...

The invention discloses a valve cutting die, and relates to the technical field of medical treatment. The die comprises a template, model marks, valve holes and valve connection overlapping holes, wherein a plurality of groups of the valve holes with different sizes are formed in the template and marked as different size models, and the valve connection overlapping holes are respectively formed inboth ends of the valve holes; and the valve holes are three valve holes which are equal and connected, and a lowest mark point is arranged under each valve hole. The die is reasonable in structural design, valve sizes and sewing sites corresponding to different aortic valve diameters are fixed to the die, so that the sewing process can be standardized, the operation time is greatly reduced, and the forming effect is ensured.
Description
technical field [0001] The invention relates to the field of medical technology, in particular to a valve cutting mold. Background technique [0002] In recent years, more and more children with aortic valve disease need clinical correction, which has become a hot spot in the treatment of pediatric heart disease. However, unlike adults, aortic valve lesions in children are mainly congenital abnormalities, often involving multiple valve leaflets, complex and serious valve leaflet lesions, and large individual differences. Therefore, surgical shaping and repair are difficult, and the re-intervention rate is high, which has become one of the difficulties in the field of pediatric heart disease treatment and has brought great challenges to pediatric cardiac surgeons. [0003] The current surgical methods for aortic valve disease include aortic valvuloplasty and valve replacement. Aortic valve replacement is the most common surgical procedure for adults with aortic valve diseas...
