软组织弹性模量测量难度主要体现在其位移无法精确获取，夹具是一个难题（对于拉应力而言），以及软组织的尺寸切割不精确。文中通过多种模具切割软组织，利用步进电机驱动偏心轮旋转，压迫组织产生形变，通过距离传感器记录组织产生的形变，再用压力传感器记录组织的受力情况，计算机采集并存储相应数据，经过模拟计算出组织的弹性参数。本文设计着重于组织的形变量的精确获取以及应力的精确获取。

It's hard to measure the elastic modulus of the soft tissue accurately.Because the stretched length of the soft tissue is diffi-cult to obtain.For tensile stress,the fixture of soft tissue is a problem,and cutting size of soft tissue is inexact.In the paper,the soft tissue is cut by the various molds.The stepper motor is used to drive the eccentric wheel,which compress the tissue.Using the dis-tance sensor records the compressed size and using pressure sensor records the forces.Then the computer collects and stores the data and then calculates the elasticity parameter of the tissue.This paper focuses on the accurate obtaining deformation as well as stress.
