Embodiment Construction
[0028] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0029] Our first purpose is to determine the membranous shell structure of the valve leaflet, and to highlight the characteristics of the valve leaflet more concretely. For this purpose, we need to have a detailed understanding of the structural characteristics of the pulmonary valve and its motion state in a cardiac cycle. According to the observation of the adult heart, it can be seen that when the pulmonary valve is closed, the valve leaflets are combined in a "Y" shape; when the pulmonary valve is open, the valve opening is similar to a circle. The technical solution for the first purpose therefore assumes that it is part of a cylindrical shell in an elastic shell.
[0030] The second purpose of the present invention is to provide the geometric shape and parameter expression of the pulmonary valve, which is the main purpose of the presen...
