摘　　要：目的比较虚拟现实和模拟训练箱在医学生腹腔镜模拟教学中的效果。方法选择在北京协和医学院八年制,即将进入临床无外科手术操作训练的见习生30人。该30人平均随机分配到两组:A组[虚拟现实组(VR组),使用虚拟现实训练系统Lap Mentor进行培训]; B组[模拟训练箱组(box组),使用simbox进行培训]。两组均进行腹腔镜基本技能的培训,培训结束后,分别要求两组在模拟训练箱内在一个乳胶手套上宽度为5 mm的圆形标记线内剪切出直径100 mm的圆,记录两组完成的时间、精确度和准确度,比较两组培训效果的差异。结果分别通过虚拟现实和模拟训练箱进行培训的两组,在腹腔镜基本技能水平上没有差异。结论通过虚拟现实和模拟训练箱进行腹腔镜技能培训的效果差不多,模拟训练箱的性价比要高于虚拟现实。Objective Laparoscopic basic skills can be learned in simulators as virtual-reality(VR)or box-trainers.However,there is no clear recommendation for either box or VR trainers as the most appropriate tool for the training of acquired laparoscopic basic skills for medical students.Methods Surgical novices without prior surgical experience(medical students,n=30).Both training tools were compared in the acquirement of basic skills.Participants completed either a box-or VR-trainer curriculum and then were asked to cut out a circle marked on a stretchable material.All groups were assessed after 1 week on both VR or box-trainers.Three main parameters were assessed,namely time,precision and accuracy.Results There were no significant differences in time,precision and accuracy in these two groups.Conclusions VR or box-trainers can both be used for simulation training for laparoscopic skills.The box-trainers have much more cost-effect than VR,and it may be applied in the training of laparoscopic skills in primary level hospitals.
