机器人手术是微创手术的辅助手段，但培训仅限于控制台时间。虚拟现实（VR）模拟已被证明是有效的腹腔镜培训，所以我们试图验证一种新的VR机器人模拟器。美国泌尿协会（AUA）教育办公室批准了这项研究。在2007年AUA年会上报名参加机器人培训课程的受试者在一个达芬奇干实验室模块和一个虚拟现实机器人模块中接受了技能培训，其中包括一个三维（3D）VR机器人模拟器。人口统计学和可接受性数据，并从模拟器的性能指标进行了比较有经验的和无经验的机器人专家之间的环转移任务。15名受试者--4名具有以前的机器人手术经验，11名没有参与。9名受试者仍在接受泌尿科培训，近一半的人报告说玩过电子游戏。da芬奇系统和模拟器的总体性能被认为是可接受的，Likert量表（0-6）评分分别为5.23和4.69。有经验的受试者在三个指标上优于无经验的受试者：总任务时间（96 s vs 159 s，P < 0.02），运动经济性（1，301 mm vs 2，095 mm，P < 0.04），以及遥控操作器在平台工作空间中心之外花费的时间（4 s vs 35 s，P < 0.02）。这是虚拟现实机器人模拟器的脸和结构有效性的最佳演示。最终需要进一步研究评估预测有效性，以支持将VR机器人模拟纳入培训课程。
Robotic surgery is an accepted adjunct to minimally invasive surgery, but training is restricted to console time. Virtual-reality (VR) simulation has been shown to be effective for laparoscopic training and so we seek to validate a novel VR robotic simulator. The American Urological Association (AUA) Office of Education approved this study. Subjects enrolled in a robotics training course at the 2007 AUA annual meeting underwent skills training in a da Vinci dry-lab module and a virtual-reality robotics module which included a three-dimensional (3D) VR robotic simulator. Demographic and acceptability data were obtained, and performance metrics from the simulator were compared between experienced and nonexperienced roboticists for a ring transfer task. Fifteen subjects-four with previous robotic surgery experience and 11 without-participated. Nine subjects were still in urology training and nearly half of the group had reported playing video games. Overall performance of the da Vinci system and the simulator were deemed acceptable by a Likert scale (0-6) rating of 5.23 versus 4.69, respectively. Experienced subjects outperformed nonexperienced subjects on the simulator on three metrics: total task time (96 s versus 159 s, P < 0.02), economy of motion (1,301 mm versus 2,095 mm, P < 0.04), and time the telemanipulators spent outside of the center of the platform's workspace (4 s versus 35 s, P < 0.02). This is the Wrst demonstration of face and construct validity of a virtual-reality robotic simulator. Further studies assessing predictive validity are ultimately required to support incorporation of VR robotic simulation into training curricula.
