A robotics practice curriculum was developed utilizing dry lab skills and testing parameters based upon the objective structured assessment of surgical tasks (OSATS) to determine its effectiveness in training novice surgeons. We recruited 20 medical students who were oriented to the DaVinci S console and instrumentation. They were pre-tested with four dry lab skills including manipulation, transection, suturing and knot tying. A control group was instructed to practice once weekly to attain proficiency and the intervention group was provided specific instructions regarding practice goals. Each subject was post-tested after a 6-week time. There were 17 students who completed the post-testing. All participants showed significant improvement in pre-test and post-test scores for manipulation (6.6-11.2, p < 0.0005), transection (3.5-6.9, p < 0.0005), knot tying (0.4-1.7, p = 0.003), and suturing (2.0-3.5, p = 0.001). There was no significant difference in pre-test and post-test scores between the control and intervention groups in manipulation, transection, knot tying, and suturing (p = 0.700, 0.782, 0.682, 0.605, respectively). Our study shows that novice surgeons such as medical students can improve dry lab robotics skills with instruction and practice.
我们利用干式实验室技能和基于手术任务客观结构化评估（OSATS）的测试参数，开发了一门机器人手术实践课程，以确定其在培训新手外科医生方面的有效性。我们招募了20名熟悉达芬奇S控制台和器械的医学生。他们接受了四项干式实验室技能的预测试，包括操作、横断、缝合和打结。对照组被要求每周练习一次以达到熟练程度，干预组则得到了关于练习目标的具体指导。六周后对每个受试者进行了后测。有17名学生完成了后测。所有参与者在操作（6.6 - 11.2，p < 0.0005）、横断（3.5 - 6.9，p < 0.0005）、打结（0.4 - 1.7，p = 0.003）和缝合（2.0 - 3.5，p = 0.001）的预测试和后测试成绩上都有显著提高。在操作、横断、打结和缝合方面，对照组和干预组的预测试和后测试成绩没有显著差异（p分别为0.700、0.782、0.682、0.605）。我们的研究表明，像医学生这样的新手外科医生可以通过指导和练习提高干式实验室机器人手术技能。
