背景资料
近年来，腹腔镜技能培训不断发展。然而，在没有现实的屏幕上视觉提示的情况下，使用传统方法传达导师的指导可能是困难和令人困惑的。为了促进腹腔镜技能转移，增强现实远程指导（ART）平台被设计成将指导者的仪器覆盖到受训者的腹腔镜监视器上。本研究的目的是比较这种新的教学模式的有效性，以传统的方法在新手执行intracerebraltask.MethodsNineteen预医学和医学生被随机分为传统的指导（n = 9）和艺术（n = 10）组腹腔镜手术和打结任务。受试者接受传统的指导或ART 1小时的腹腔镜手术的基本原理，腹腔镜手术任务。记录任务，并对时间和错误进行评分。结果进行了分析，使用平均值，标准差，功率回归分析，相关系数，方差分析，和学生的t test.ResultsUsing赖特的累积平均模型（Y = aXb）的学习曲线斜率显着陡峭，表现出更快的技能获取，为艺术组（B =-0.567，r2 = 0.92）高于对照组（B =-0.453，r2 = 0.74）。在10次重复或1小时的练习结束时，ART组比传统组更快（平均167.4 vs. 242.4 s，p = 0.014）。ART组也有较少的失败（8）比传统组（13）。ConclusionThe ART平台可能是一个更有效的培训技术，在教腹腔镜技能的新手相比，传统的方法。ART提供了更短的学习曲线，这在前4次试验中更为明显。ART减少了失败尝试的次数，并在培训课程结束时缩短了缝合时间。ART可能是一个更有效的培训工具，在腹腔镜手术培训复杂的任务比传统的方法。
AbstractBackground
Laparoscopic skills training has evolved over recent years. However, conveying a mentor’s directions using conventional methods, without realistic on-screen visual cues, can be difficult and confusing. To facilitate laparoscopic skill transference, an augmented reality telementoring (ART) platform was designed to overlay the instruments of a mentor onto the trainee’s laparoscopic monitor. The aim of this study was to compare the effectiveness of this new teaching modality to traditional methods in novices performing an intracorporeal suturing task.MethodsNineteen pre-medical and medical students were randomized into traditional mentoring (n = 9) and ART (n = 10) groups for a laparoscopic suturing and knot-tying task. Subjects received either traditional mentoring or ART for 1 h on the validated fundamentals of laparoscopic surgery intracorporeal suturing task. Tasks for suturing were recorded and scored for time and errors. Results were analyzed using means, standard deviation, power regression analysis, correlation coefficient, analysis of variance, and student’s t test.ResultsUsing Wright’s cumulative average model (Y = aXb) the learning curve slope was significantly steeper, demonstrating faster skill acquisition, for the ART group (b = −0.567, r2 = 0.92) than the control group (b = −0.453, r2 = 0.74). At the end of 10 repetitions or 1 h of practice, the ART group was faster versus traditional (mean 167.4 vs. 242.4 s, p = 0.014). The ART group also had fewer fails (8) than the traditional group (13).ConclusionThe ART Platform may be a more effective training technique in teaching laparoscopic skills to novices compared to traditional methods. ART conferred a shorter learning curve, which was more pronounced in the first 4 trials. ART reduced the number of failed attempts and resulted in faster suture times by the end of the training session. ART may be a more effective training tool in laparoscopic surgical training for complex tasks than traditional methods.
