机器人腹腔镜手术彻底改变了腹部疾病治疗的微创手术。然而，目前的培训技术依赖于主观评价。作者试图通过在三个训练任务中比较新手和专家来确定机器人手术表现的客观衡量标准。五名新手（医学生）接受了达芬奇手术系统的三个任务训练。五名受过先进腹腔镜训练的专家也执行了这三项任务。测量任务完成时间（TTC）、总行进距离(D)、速度(S)、曲率（kappa）和相对相位（I断裂垂直杆）。培训前专家组TTC、D、kappa显著小于新手组（p < 0.05），培训前专家组S显著大于新手组（p < 0.05）。新手训练后的表现显著优于专家，TTC、D、kappa值较小，s值较大。这项研究清楚地证明了客观运动学测量在机器人外科训练任务中区分新手和专家表现和训练效果的能力。
Robotic laparoscopic surgery has revolutionized minimally invasive surgery for the treatment of abdominal pathologies. However, current training techniques rely on subjective evaluation. The authors sought to identify objective measures of robotic surgical performance by comparing novices and experts during three training tasks.Five novices (medical students) were trained in three tasks with the da Vinci Surgical System. Five experts trained in advanced laparoscopy also performed the three tasks. Time to task completion (TTC), total distance traveled (D), speed (S), curvature (kappa), and relative phase (I broken vertical bar) were measured.Before training, TTC, D, and kappa were significantly smaller for experts than for novices (p < 0.05), whereas S was significantly larger for experts than for novices before training (p < 0.05). Novices performed significantly better after training, as shown by smaller TTC, D, and kappa, and larger S. Novice performance after training approached expert performance.This study clearly demonstrated the ability of objective kinematic measures to distinguish between novice and expert performance and training effects in the performance of robotic surgical training tasks.
