提供信息丰富的反馈和设定目标往往会激励学员进行更广泛的练习。增强现实模拟器保留了真实触觉反馈的好处，并在培训期间另外生成客观评估和信息性反馈。研究了Promis增强现实模拟器上自适应缝合模块的性能曲线。18名新手参与者接受了MIST-VR的预培训，以熟悉腹腔镜检查。随后，他们在缝合模块上练习16节，并记录评估分数，以评估腹腔镜缝合技能的收益。该评估方法的得分是根据打结时在正确区域花费的时间和打结的质量来计算的。两个独立的客观观察者通过标准化评估表对基线结和性能曲线顶端的结进行评估，以客观化缝合技术的收益。第二个节点的得分(平均值72.59，标准差(SD)16.28)与性能曲线顶端的得分(平均值95.82，SD3.05；p>0.001，配对t检验)相比，差异有统计学意义。客观观察者的得分也有显著差异(分别为11.83和22.11；SD分别为3.37和3.89；P<0.001)(观察者间信度Cronbach‘sα=0.96)。达到绩效曲线顶端的重复次数的中位数是8次，这也显示出评估得分(平均值88.14SD13.53，P<0.001)和第二个结的客观观察者的得分(平均值20.51SD4.14；P<0.001)之间的显著差异。Promis增强现实腹腔镜模拟器上的这个经过调整的缝合模块是获得腹腔镜缝合技能的有力工具。
Providing informative feedback and setting goals tends to motivate trainees to practice more extensively. Augmented Reality simulators retain the benefit of realistic haptic feedback and additionally generate objective assessment and informative feedback during the training. This study researched the performance curve of the adapted suturing module on the ProMIS Augmented Reality simulator. Eighteen novice participants were pretrained on the MIST-VR to become acquainted with laparoscopy. Subsequently, they practiced 16 knots on the suturing module, of which the assessment scores were recorded to evaluate the gain in laparoscopic suturing skills. The scoring of the assessment method was calculated from the “time spent in the correct area” during the knot tying and the quality of the knot. Both the baseline knot and the knot at the top of the performance curve were assessed by two independent objective observers, by means of a standardized evaluation form, to objectify the gain in suturing skills. There was a statistically significant difference between the scores of the second knot (mean 72.59, standard deviation (SD) 16.28) and the top of the performance curve (mean 95.82, SD 3.05; p < 0.001, paired t-test). The scoring of the objective observers also differed significantly (mean 11.83 and 22.11, respectively; SD 3.37 and 3.89, respectively; p < 0.001) (interobserver reliability Cronbach’s alpha = 0.96). The median amount of repetitions to reach the top of the performance curve was eight, which also showed significant differences between both the assessment score (mean 88.14, SD 13.53, p < 0.001) and scoring of the objective observers of the second knot (mean 20.51, SD 4.14; p < 0.001). This adapted suturing module on the ProMIS Augmented Reality laparoscopic simulator is a potent tool for gaining laparoscopic suturing skills.
