背景手术模拟器可以实施手术training的评估，其结构效度should be assessed.Methods九个新手（NOV），九个医学生（MS），和九个居民（RES）进行了腹腔镜技能培训的虚拟现实（VR）模拟器圈导师（R）。评估腹腔镜技能的基础上测量的参数由计算机系统的培训before and after training.Results之间存在显着差异RES和NOV在7的9个任务之前的VR模拟器上培训。在某些任务的培训后，观察到经验组（RES）和非经验组（MS和NOV）之间或医疗组（RES和MS）和非医疗组（NOV）之间的显着差异。结论Lap-Mentor（R）的性能参数可以用来区分不同的腹腔镜经验的受试者。
Background Before surgical simulators can be implemented for assessment of surgical training, their construct validity should be assessed.Methods Nine novices (NOV), nine medical students (MS), and nine residents (RES) underwent a laparoscopic skills training on the virtual reality (VR) simulator Lap Mentor (R). Assessment of laparoscopic skill was based on parameters measured by the computer system before and after training.Results Significant difference existed between RES and NOV at seven of nine tasks before training on the VR simulator. After the training in some tasks significant differences were observed between the experienced group (RES) and the nonexperienced groups (MS and NOV) or between medical groups (RES and MS) and nonmedical group (NOV).Conclusions Performance parameters of the Lap-Mentor (R) can be used to distinguish between subjects with varying laparoscopic experience.
