目的：我们评估了新的da芬奇（R）技能模拟器（TM）使用的da芬奇Si（TM）外科医生控制台作为Surgeon interfaces.Materials和Methods：我们评估了一种新的机器人手术模拟器的机器人手术使用的da芬奇Si外科医生控制台和Mimic（TM）虚拟现实。受试者被分类为新手-没有手术培训，中级-手术培训少于100个机器人病例或专家-100个或更多的主要外科医生机器人病例。每个参与者完成了10个虚拟现实练习，重复3次，并完成了一份1至10视觉模拟量表的问卷，以评估模拟器的真实性（表面有效性）和培训有用性（内容有效性）。模拟器根据特定指标记录性能。使用Kruskal-Wallis检验比较了专家、中间人和新手的表现（结构有效性）。结果：我们研究了16名新手、32名中间人，中位手术经验为6年（范围1至37），中位机器人病例为0（范围0至50），15名专家，中位机器人病例为315例（范围100至800）。参与者将虚拟现实和控制台体验评为非常逼真（中位数视觉模拟量表评分为8/10），而专家外科医生将模拟器评为非常有用的住院医师（10/10）和研究员（9/10）培训工具。专家在几乎所有指标上都优于中级和新手（组间总得分中位数分别为88.3%、75.6%和62.1%，P
Purpose: We evaluated the face, content and construct validity of the novel da Vinci(R) Skills Simulator (TM) using the da Vinci Si (TM) Surgeon Console as the surgeon interface.Materials and Methods: We evaluated a novel robotic surgical simulator for robotic surgery using the da Vinci Si Surgeon Console and Mimic (TM) virtual reality. Subjects were categorized as novice-no surgical training, intermediate-surgical training with fewer than 100 robotic cases or expert-100 or more primary surgeon robotic cases. Each participant completed 10 virtual reality exercises with 3 repetitions and a questionnaire with a 1 to 10 visual analog scale to assess simulator realism (face validity) and training usefulness (content validity). The simulator recorded performance based on specific metrics. The performance of experts, intermediates and novices was compared (construct validity) using the Kruskal-Wallis test.Results: We studied 16 novices, 32 intermediates with a median surgical experience of 6 years (range 1 to 37) and a median of 0 robotic cases (range 0 to 50), and 15 experts with a median of 315 robotic cases (range 100 to 800). Participants rated the virtual reality and console experience as very realistic (median visual analog scale score 8/10) while expert surgeons rated the simulator as a very useful training tool for residents (10/10) and fellows (9/10). Experts outperformed intermediates and novices in almost all metrics (median overall score 88.3% vs 75.6% and 62.1%, respectively, between group p
