基于LabVIEW的内窥镜手柄工效学评价系统设计

摘要

A system which can make ergonomic evaluation of the endoscope handle is designed. During the sim ulated endoscope surgical procedures, the surface contact pressure between the human hand and the endoscope handle and the SEMG of the forearm are collected. Through data analysis and processing, the curve surface pressure distribution of the endoscopy and the local SEMG characteristics of human are obtained, which provides an objective and valid experiment data for the ergonomic evaluation of the design of an endoscope handle.%设计了一个能够对内窥镜手柄进行工效学评价的系统,在模拟内窥镜手术操作实验的过程中采集人体手部与内窥镜手柄的表面接触压力以及手臂的表面肌电信号.通过对数据的分析与处理得到了内窥镜手术过程中手柄的表面压力分布情况,以及人体局部肌电信号的特征值,为内窥镜手柄设计的工效学评价提供了客观、有效的实验数据.
