【摘要】 目的比较经脐入路内镜手术(TUES)3种不同器械置入装置(Multi-ports、TriPort、SILSPort)的灵活性。方法 2010年6月至2011年3月用腹腔镜模拟训练箱和Multi-ports、TriPort、SILSPort组建TUES评估平台,通过万能材料试验机水平牵引实验与力应变反馈实验,对3种TUES置入装置进行评估。结果水平牵引实验中,作用于3组Port的牵引力:Multi-ports组<SILSPort组<TriPort组,3组间牵引力差异均有统计学意义(P<0.05)。力反馈实验操作所用的力,以Multi-ports为最小,Multi-ports组与TriPort组组间、SILSPort组与TriPort组组间差异有统计学意义(P<0.05),而Multi-ports组与SILSPort组组间差异无统计学意义(P>0.05)。结论 3种常用的TUES置入装置中,Multi-ports所需力最小,操作中相对更为灵活。更多还原

【Abstract】 Objective The aim of this study was to evaluate the access devices in transumbilical endoscopic surgery in a training simulator. Methods From June 2010 to March 2011, Multi-ports, TriPort and SILS Port were compared through the horizontal traction experiment and the force feedback experiment, on which a measuring platform was set up with different access devices and a universal testing machine. Results In the horizontal traction experiment, the different forces on the instruments in the access devices were detected significantly ( Multi-ports < SILS Port < TriPort )( P < 0.05 ). In the force feedback experimental, Multi-ports had used least force, the difference between Multi-ports group and TriPort group was statistically significant ( P < 0.05 ). There was marked difference between SILS Port group and TriPort group ( P < 0.05 ), but there was no significant difference between Multi-ports group and SILS Port group ( P > 0.05 ). Conclusions Compared with SILS Port and TriPort, Multi-ports are associated with the least force and relatively the most flexible use in a training simulator.更多还原
