【摘要】 目的评估经脐入路腹腔镜手术中常用3种Port的灵活性。方法用腹腔镜操作训练箱、薄膜应变片和动静态应变测试采集系统组建应变测力传感装置,比较使用不同Port完成相同操作的用力和时间。结果完成相同标准操作用力Multi-ports组最小,且用力显著小于TriPort组[右手(0.68±0.12)N vs.(1.33±0.22)N,P=0.000;左手(0.66±0.18)N vs.(1.25±0.21)N,P=0.000],SILS Port组用力显著小于TriPort组[右手(0.92±0.29)N vs.(1.33±0.22)N,P=0.003;左手(0.82±0.18)N vs.(1.25±0.21)N,P=0.001]。Multi-ports组完成操作时间最短,显著少于SILS Port组[(76.6±17.8)s vs.(105.9±27.2)s,P=0.030)和TriPort组[(76.6±17.8)s vs.(106.3±23.9)s,P=0.028]。结论 3种置入装置中,完成相同标准操作Multi-ports用力较小、所需时间最少,操作相对更为灵活。更多还原

【Abstract】 Objective To evaluate the flexibility of three common access devices in transumbilical laparoscopic surgery.Methods A strain force measurement system,which was composed of a training simulator,strain gauges and force sensing systems mounted with a dedicated software,was set up.Based on this system,the forces and operaton time were compared among Multi-ports,TriPort and SILS Port,when a standard task was performed.Results Compared to TriPort group,Multi-ports group had significantly lower mean operation force [right hand:(0.68±0.12) N vs.(1.33±0.22) N,P=0.000;left hand:(0.66±0.18) N vs.(1.25±0.21) N,P=0.000].The SILS Port group showed significantly lower mean operation force than TriPort group [right hand:(0.92±0.29) N vs.(1.33±0.22) N,P=0.003;left hand:(0.82±0.18) N vs.(1.25±0.21) N,P=0.001].And Multi-ports group had significantly shorter operation time than both SILS Port [(76.6±17.8) sec vs.(105.9±27.2) sec,P=0.030) and TriPort groups [(76.6±17.8) sec vs.(106.3±23.9) sec,P=0.028].Conclusion Considering its least force and shortest operation time,we recommend Multi-ports as the most flexible device in a training simulator.更多还原
