【摘要】 研究了猪十二指肠和空肠的生物力学性能 ,结果表明 :其应力 应变关系为指数函数关系。从材料常数C和α比较来看 ,十二指肠和空肠的指数系数α值较接近 ,这说明十二指肠和空肠应力应变趋势是一致的。在一定应变下 ,十二指肠的增量弹性模量大于空肠的增量弹性模量。这说明 ,空肠更容易发生变形。本试验研究为研制体内运行的医用微型机器人提供基础数据。更多还原

【Abstract】 The biomechanics behavior of pig such as duodenum and jejunum are studied and a formulation of the stress-strain relation is presented.The results indicate that the exponential coefficient α of each is almost the same and the incremental elastic modulus of duodenum is larger than those of jejunumand.That is to say,the jejunum can be more easily deformed and the biomechanics behavior of the duodenum and the jejunum is almost the same.The results are necessary for study on the Noninvasive method to drive a Medical Microrobot.更多还原
