| 摘 要： | 目的 对不同经脐入路腹腔镜手术器械置入装置(Port)进行力学评估,比较在模拟操作过程中这些置入装置的操作灵活性.方法 用腹腔镜模拟训练箱和3种常用的经脐入路腹腔镜手术Port(Multi-ports、TriPort、SILS Port)组建评估平台.用万能材料试验机通过水平、垂直牵引实验产生对应于位移的受力曲线,对3种Port进行水平和垂直方向的力学评估.结果 水平牵引实验中,作用于3组Port的牵引力,Multi-ports组＜SILS Port组＜TriPort组,3组间牵引力差异均有统计学意义(P＜0.05).垂直牵引实验中,手术器械在Port通道中垂直推进时受力,Multi-ports组＜SILS Port组＜TriPort组,3组间差异均有统计学意义(P＜0.05);手术器械在通道中垂直退出时受力,Multi-ports组＜TriPort组＜SILS Port组,3组间差异均有统计学意义(P＜0.05).结论 3种常用的经脐入路手术Port进行水平和垂直方向移动时,Multi-ports所需力最小,操作相对更为灵活.

| Abstract: | Objective To make the horizontal and vertical mechanical evaluation for different access devices (Port) in transumbilical laparoscopic surgery, and to compare the maneuverabilities of these devices during the process. MethodsA laparoscopic training box was combined with Multi-ports, TriPort and SILS Port to construct the evaluation platforms. A universal testing machine was used for evaluating the mechanics of the three devices on horizontal and vertical direction by traction experiments. ResultsIn the horizontal traction experiment, the forces were significantly different on the instruments with different access devices (Multi-ports
