The primary objective of this study is to determine if training on the Mimic dV-Trainer (MdVT) simulator results in improved ability on the da Vinci surgical system (dVSS) using exercises with inanimate objects.
Twelve trainees (MdVT group) and 10 residents and one fellow (dVSS group) were recruited for the study. Each participant in the MdVT group completed one session of five exercises on the dVSS that were scored for timing and accuracy, followed by four training sessions on the MdVT, and concluded with a final session on the dVSS in which the initial exercises were repeated. Improvement on the dVSS exercises was compared with dVSS group who completed four to six training sessions using the same exercises on the dVSS without any simulator training.
Both groups had similar significant improvements in the Letter Board and String Running exercises for both timing and accuracy. The MdVT group demonstrated significant improvement in the Pattern Cutting and Peg Board times. Only the dVSS group significantly improved in the Knot Tying time and the Peg Board accuracy.
Training with the MdVT provided similar improvement on five exercises performed on the dVSS when compared with training on the dVSS alone. The use of this simulator in resident and student training may help bridge the gap between the safe acquisition of surgical skills and effective performance during live robot-assisted surgery.
本研究的主要目的是确定在 Mimic dV-Trainer（MdVT）模拟器上进行训练是否会通过使用无生命物体的练习来提高达芬奇手术系统（dVSS）的操作能力。
本研究招募了 12 名受训者（MdVT 组）和 10 名住院医师和 1 名研究员（dVSS 组）。MdVT 组的每位参与者都在 dVSS 上完成了 5 项练习，这些练习的时间和准确性都进行了评分，随后进行了 4 次 MdVT 训练，最后在 dVSS 上进行了一次练习，重复了最初的练习。与仅在 dVSS 上使用相同练习进行 4 到 6 次训练的 dVSS 组相比，比较了 dVSS 练习的改进情况。
两组在字母板和线绳跑动练习中，无论是时间还是准确性都有明显的提高。MdVT 组在模式切割和钉板时间上也有显著提高。只有 dVSS 组在打结时间和钉板准确性上有显著提高。
与单独在 dVSS 上训练相比，使用 MdVT 进行训练可在进行 dVSS 五项练习时提供类似的改善。在住院医师和学生培训中使用这种模拟器可能有助于弥合安全获得手术技能与在实际机器人辅助手术中有效操作之间的差距。
