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...

Abstract

The invention discloses an establishment method for a mathematical model of the geometrical shape of a pulmonary valve. The method comprises the steps that based on motion characteristics of the pulmonary valve in a cardiac cycle, it is assumed that the valve is in symmetry, and only a single lobe is researched; based on structural and physiological characteristics of the pulmonary valve, it is assumed that the pulmonary valve is a part of a cylindrical shell in an elastic shell body; according to medical images and relevant data, a fitting function is found, and the shape of the lobe and relevant parameters are determined; and the conclusion is verified through data, and the accuracy of the research result is determined. In the research process, based on the similarity between structures and sizes of three lobes, it is assumed that the lobes are in complete symmetry, only one lobe is researched, and therefore the problem is simplified; and the given mathematical model of the geometrical shape of the pulmonary valve has a certain theoretical basis and accuracy, will be beneficial for treating diseases about the pulmonary valve in clinical medicine and is more beneficial for reconstruction of heart valve prosthesis substitute goods in medicine.

Description

technical field [0001] The invention relates to the technical field of mathematical models, in particular to a method for establishing a mathematical model of the geometric shape of a pulmonary valve. Background technique [0002] The heart is a particularly complex and important organ of the human body. It mainly consists of two chambers and two chambers. The atria receive the return blood from the veins, and the ventricles pump the centrifugal blood into the arteries. The connection between the chambers mainly depends on valves. The human heart There are four groups of valves: mitral, tricuspid, aortic, and pulmonary. These valves are delicately combined through close connections. The main function of the heart valves is that the blood in the heart crosses each other in two separate spaces, so that the blood flows in the appropriate direction and supplies oxygen and nutrients to the organs and tissues, preventing heart failure. Reflux phenomenon. In view of the vital rol...
