Problems solved by technology

In this case, the original equal-scale simulated wooden legs used in the test of human legs showed certain shortcomings, such as the entire leg is hardened and cannot be bent, ignoring the difference in the movement posture of the legs may cause The change trend of the pressure value, so that when the experiment is carried out, the influence factors of the micro size change and the different posture changes of the human legs cannot be taken into account, which makes the error of the experiment larger

Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0025] refer to figure 1 As shown, a pressure distribution measurement method based on medical simulation soft legs, the specific steps include:

[0026] Obtain the leg data of the standard vertebral body to build a three-dimensional solid model of simulated soft legs;

[0027] The three-dimensional solid model of the simulated soft leg, that is, the simulated soft leg is mainly composed of skin and bones, and the skin and bones of the simulated soft leg are defined as isotropic and uniform linear elastic materials, wherein the thickness of the skin in the simulated soft leg is 1.5- 2.5cm, hardness 0A, with 300% elongation; the bones are divided into foot bone, tibia and leg bone...

Abstract

The invention relates to the technical field of human body simulation, in particular to a pressure distribution measurement method established based on a medical simulation soft leg. The medical simulation soft leg has the same structure and size as the human leg, the simulated soft leg has an elastic touch sense, knee joints and ankle joints can move and can hover at any position, and the structure is similar to the actual human leg structure. The obtained pressure distribution change value is close to the pressure distribution change value measured by the legs of the human body. The experiment process becomes simple, the experiment result is more accurate. Meanwhile, a better effect is achieved for an experiment for measuring human leg pressure distribution, the obtained pressure distribution value accurate value is also larger than the pressure distribution value of the equal-proportion simulation wooden leg, and wide application prospects are achieved.

Description

technical field [0001] The invention relates to the technical field of human body simulation, and relates to a pressure distribution measurement method based on medical simulated soft legs. Background technique [0002] At present, with the advancement of science and technology, human body simulation technology has shown obvious advantages in measurement and calculation. In this case, the original equal-scale simulated wooden legs used in the test of human legs showed certain shortcomings, such as the entire leg is hardened and cannot be bent, ignoring the difference in the movement posture of the legs may cause The change trend of the pressure value, so that when the experiment is carried out, the micro size change caused by it and the influencing factors of the different posture changes of the human leg cannot be taken into account, which makes the error of the experiment larger. Contents of the invention [0003] The technical problem to be solved by the present invent...
