This study was undertaken to compare performance using a surgical robot after training with one of three simulators of varying fidelity.
Eight novice operators and eight expert surgeons were randomly assigned to one of three simulators. Each participant performed two exercises using a simulator and then using a surgical robot. The primary outcome of this study is performance assessed by time and GEARS score.
Participants were randomly assigned to one of three simulators. Time to perform the suturing exercise (novices vs. experts) was significantly different for all 3 simulators. Using the da Vinci robot, peg transfer showed no significant difference between novices and experts and all participants combined (mean time novice 2.00, expert 2.21, = 0.920). The suture exercise had significant differences in each group and all participants combined (novice 3.54, expert 1.90, = 0.001). ANOVA showed -Values for suturing (novice 0.523, expert 0.123) and peg transfer (novice 0.742, expert 0.131) are not significantly different. GEARS scores were different ( < 0.05) for novices and experts.
Training with simulators of varying fidelity result in similar performance using the da Vinci robot. A dry box simulator may be as effective as a virtual reality simulator for training. Further studies are needed to validate these results.
本研究旨在比较在使用三种不同逼真度模拟器之一进行训练后使用手术机器人的操作表现。
八名新手操作员和八名专家外科医生被随机分配到三种模拟器中的一种。每位参与者使用模拟器进行两项练习，然后使用手术机器人。本研究的主要结果是通过时间和GEARS评分评估的操作表现。
参与者被随机分配到三种模拟器中的一种。所有三种模拟器在进行缝合练习的时间（新手与专家）上均存在显著差异。使用达芬奇机器人时，新手和专家以及所有参与者在进行钉转移操作时均无显著差异（新手平均时间2.00，专家2.21，P = 0.920）。缝合练习在每组以及所有参与者中均存在显著差异（新手3.54，专家1.90，P = 0.001）。方差分析显示，缝合（新手0.523，专家0.123）和钉转移（新手0.742，专家0.131）的P值无显著差异。新手和专家的GEARS评分不同（P < 0.05）。
使用不同逼真度的模拟器进行训练，使用达芬奇机器人时的操作表现相似。干式箱模拟器在训练方面可能与虚拟现实模拟器一样有效。需要进一步研究来验证这些结果。
