目的验证机器人辅助手术技能收购使用增强现实（AR）为基础的模块urethrovesical吻合术（UVA）。MethodsParticipants在三个机构被随机分配到动手术手术培训（主机）技术组或对照组。HostST组在基于AR的HostST环境中接受了基于程序的UVA培训。对照组不接受任何训练。完成任务后，对照组被提供交叉到主机组（交叉组）。在HostT之后进行的问卷调查确定了该技术的可行性和可接受性。在daVinci手术系统（Intuitive Surgical Inc.，桑尼维尔，CA，USA）使用UVA评估分数和机器人技能的全球评估性评估（GEARS）分数进行评估。参与者完成了美国国家航空航天局任务负荷指数（NASA TLX）的认知评估问卷，作为结果的措施。A Wilcoxon秩和检验被用来比较各组之间的结果（主机组与对照组和对照组与交叉组）。UVA评价评分显示，HostST组与对照组在针驱动（3.0 vs 2.3; P = 0.042）、针定位（3.0 vs 2.4; P = 0.033）和缝线放置（3.4 vs 2.6; P = 0.014）方面存在显著差异。HostST组的GEARS评分显著更高（14.4 vs 11.9; P 0.012）。NASA TLX显示HostST组的时间需求和努力较低（分别为5.9 vs 9.3; P = 0.001和5.8 vs 11.9; P = 0.035）。在所有的，70%的参与者发现，主机是类似的真实的外科手术，75%的人认为，主机可以提高信心进行的真实的intervention.ConclusionTraining在UVA在AR环境中提高了技术技能的收购与最小的认知需求。
ObjectiveTo validate robot-assisted surgery skills acquisition using an augmented reality (AR)-based module for urethrovesical anastomosis (UVA).MethodsParticipants at three institutions were randomised to a Hands-on Surgical Training (HoST) technology group or a control group. The HoST group was given procedure-based training for UVA within the haptic-enabled AR-based HoST environment. The control group did not receive any training. After completing the task, the control group was offered to cross over to the HoST group (cross-over group). A questionnaire administered after HoST determined the feasibility and acceptability of the technology. Performance of UVA using an inanimate model on the daVinci Surgical System (Intuitive Surgical Inc., Sunnyvale, CA, USA) was assessed using a UVA evaluation score and a Global Evaluative Assessment of Robotic Skills (GEARS) score. Participants completed the National Aeronautics and Space Administration Task Load Index (NASA TLX) questionnaire for cognitive assessment, as outcome measures. A Wilcoxon rank-sum test was used to compare outcomes among the groups (HoST group vs control group and control group vs cross-over group).ResultsA total of 52 individuals participated in the study. UVA evaluation scores showed significant differences in needle driving (3.0 vs 2.3; P = 0.042), needle positioning (3.0 vs 2.4; P = 0.033) and suture placement (3.4 vs 2.6; P = 0.014) in the HoST vs the control group. The HoST group obtained significantly higher scores (14.4 vs 11.9; P 0.012) on the GEARS. The NASA TLX indicated lower temporal demand and effort in the HoST group (5.9 vs 9.3; P = 0.001 and 5.8 vs 11.9; P = 0.035, respectively). In all, 70% of participants found that HoST was similar to the real surgical procedure, and 75% believed that HoST could improve confidence for carrying out the real intervention.ConclusionTraining in UVA in an AR environment improves technical skill acquisition with minimal cognitive demand.
