Full-procedure virtual reality (VR) simulator training in robotic-assisted radical prostatectomy (RARP) is a new tool in surgical education.
Description of the development of a VR RARP simulation model, (RobotiX-Mentor®) including non-guided bladder neck (ngBND) and neurovascular bundle dissection (ngNVBD) modules, and assessment of face, content, and construct validation of the ngBND and ngNVBD modules by robotic surgeons with different experience levels.
Simulator and ngBND/ngNVBD modules were rated highly by all surgeons for realism and usability as training tool. In the ngBND-task construct, validation was not achieved in task-specific performance metrics. In the ngNVBD, task-specific performance of the expert/intermediately experienced surgeons was significantly better than that of novices.
We proved face and content validity of simulator and both modules, and construct validity for generic metrics of the ngBND module and for generic and task-specific metrics of the ngNVBD module.
全流程虚拟现实（VR）模拟器培训在机器人辅助根治性前列腺切除术（RARP）中是一种新的手术教育工具。
描述了一种 VR RARP 模拟模型（RobotiX-Mentor®）的开发，包括非引导性膀胱颈部（ngBND）和神经血管束解剖（ngNVBD）模块，并由具有不同经验水平的机器人外科医生评估 ngBND 和 ngNVBD 模块的表面效度、内容效度和结构效度。
所有外科医生都对模拟器和 ngBND/ngNVBD 模块的真实性和可用性给予了高度评价，认为它们是一种很好的培训工具。在 ngBND 任务的结构中，在特定任务的表现指标上没有达到验证标准。在 ngNVBD 中，专家/中级经验外科医生的特定任务表现明显优于新手。
我们证明了模拟器和两个模块的表面效度和内容效度，以及 ngBND 模块的通用指标和 ngNVBD 模块的通用和特定任务指标的结构效度。
