Surgical training of students is one of the most difficult aspects of veterinary medical education. Competing interests of house officers, owners' wishes, and ethical concerns have led to increasing use of inanimate models for basic surgical skills training. Robotic simulators have benefits for psychomotor training but have not been previously investigated in veterinary medicine. Understanding the necessary practice time for new training devices is important when determining their potential value. The aim of this study was to compare the number of attempts needed for veterinary students to reach proficiency in both a basic and advanced robotic simulator task, and to assess the predictive nature of performance variables. Each student performed a basic and advanced tasks on the Mimic dV-Trainer™ until proficiency was reached. Students required a median of eight attempts (95% CI = 7-8, range: 6-11) to reach proficiency for the basic task versus 22 attempts (95% CI = 20-26, range: 11-62) for the advanced task. The median time required to complete training for the basic and advanced task was 13.5 minutes (range: 8-24 minutes) and 26.5 minutes (range: 11-82 minutes) respectively. The difference in task attempts supports the training protocol and confirms proficiency can be attained in a short period of time. The number of attempts to reach proficiency correlated with specific performance variables that can be used by educators to aid in training students on a robotic simulator. Continued investigations on robotic simulators should be performed to investigate their use in improving psychomotor skills in veterinary students.
学生的外科培训是兽医医学教育中最困难的方面之一。住院医师、所有者的意愿和伦理问题之间的利益冲突导致越来越多地使用无生命模型进行基本手术技能培训。机器人模拟器具有运动技能训练的优势，但在兽医领域尚未得到研究。在确定其潜在价值时，了解新培训设备所需的实践时间非常重要。本研究的目的是比较兽医学生达到基本和高级机器人模拟器任务熟练程度所需的尝试次数，并评估性能变量的预测性质。每位学生都在 Mimic dV-Trainer™ 上执行了基本任务和高级任务，直到达到熟练程度。学生需要进行中位数为 8 次尝试（95%CI=7-8，范围：6-11）才能达到基本任务的熟练程度，而高级任务则需要 22 次尝试（95%CI=20-26，范围：11-62）。完成基本和高级任务的中位数培训时间分别为 13.5 分钟（范围：8-24 分钟）和 26.5 分钟（范围：11-82 分钟）。达到熟练程度所需的尝试次数差异支持培训方案，并确认可以在短时间内达到熟练程度。达到熟练程度所需的尝试次数与特定的性能变量相关，教育者可以使用这些变量来帮助学生在机器人模拟器上进行培训。应继续对机器人模拟器进行研究，以调查它们在提高兽医学生运动技能方面的应用。
