摘　　要：基于时频联合分析法(JASA),开展基于表面肌电信号的脊柱手术器械上肢操作肌肉疲劳评估研究,完成脊柱手术器械优化前后操作舒适性的对比测评。共招募17名受试者分别采集其肱桡肌和肱二头肌的表面肌电信号,选取5种优化前后的手术器械进行数据对比,基于RMS和MF特征值计算相同任务下各组器械的操作疲劳时间占比。结果表明完成相同操作任务时,优化前手术器械的操作疲劳时间显著高于优化后器械(P<0.05);操作同一器械,肱桡肌和肱二头肌疲劳状态无显著性差异(P>0.05),这为手术器械的人因学设计及疲劳损伤防护等提供客观数据及参考。Based on the joint analysis of EMG spectrum and amplitude method(JASA),a study on muscle fatigue assessment of spinal surgical instruments based on surface EMG signals was carried out,and a comparative evaluation of the operating comfort before and after the optimization of spinal surgical instruments was completed.A total of 17 subjects were recruited to collect the surface EMG signals of their brachioradialis and biceps.Five surgical instruments before and after optimization were selected for data comparison,and the operating fatigue time proportion of each group of instruments under the same task was calculated based on the RMS and MF eigenvalues.The results showed that when completing the same operation task,the operation fatigue time of the surgical instruments before optimization was significantly higher than that after optimization(P<0.05);there was no significant difference in the fatigue status of brachioradialis and biceps when operating the same instrument(P>0.05).These results provide objective data and reference for the ergonomic design of surgical instruments and fatigue damage protection.
