人体股前区皮肤生物力学特性的初步研究

采用ＨＬＣ－１型生物活组织力学试验机对正常成年人股前区皮肤进行生物力学测定。结果表明，股前区皮肤垂直于皮纹方向的应力与应变之间呈指数函数关系，当应变在１．２以内时，应变增加而应力增加不明显，而当应变大于１．２时，应力急剧增加。提示不论伤口缝合及植皮手术时皮肤应变范围应在１．２内为宜。

Preliminary Study of Biomechanic Property on Human Forethigh Skin

HLCO- I biomechanical living-tissues testing mechanic was adopted for testing the biomechanical property of normal adult forethigh skin. The figures acquired were calculated using one dimension strain energy function and the constitutive equation of mono-way stress and strain was established. The results showed that the relationship between stress and strain could be expressed by the exponential function. The rise of stress was not ev-ident when th e strain was lower than 1. 2,but the stress rose much sharply when the strain was higher than 1. 2.The curves were nonlinear. This suggests that when we sew up a wound or perform skin transplantation,the strain should be lower than 1, 2.
