To evaluate virtual reality as a laparoscopic training device in helping surgeons to automate to the "fulcrum effect" by comparing it to time-matched training programs using randomly alternating images (ie, y-axis inverted and normal laparoscopic) and normal laparoscopic viewing conditions.
Twenty-four participants (16 females and 8 males), were randomly assigned to minimally invasive surgery virtual reality (MIST VR), randomly alternating (between y-axis inverted and normal laparoscopic images), and normal laparoscopic imaging condition. Participants were requested to perform a 2-minute laparoscopic cutting task before and after training.
In the test trial participants who trained on the MIST VR performed significantly better than those in the normal laparoscopic and randomly alternating imaging conditions.
The results show that virtual reality training may provide faster skill acquisition with particular reference to automation of the fulcrum effect. MIST VR provides a new way of training laparoscopic psychomotor surgical skills.
通过将虚拟现实作为一种腹腔镜训练设备，与使用随机交替图像（即y轴倒置和正常腹腔镜图像）以及正常腹腔镜观察条件的时间匹配训练程序进行比较，评估其帮助外科医生实现“支点效应”自动化的效果。
24名参与者（16名女性和8名男性）被随机分配到微创外科虚拟现实（MIST VR）组、随机交替（y轴倒置和正常腹腔镜图像之间）组和正常腹腔镜成像条件组。要求参与者在训练前后各进行一项2分钟的腹腔镜切割任务。
在测试试验中，接受MIST VR训练的参与者表现明显优于正常腹腔镜和随机交替成像条件组的参与者。
结果表明，虚拟现实训练可能会更快地掌握技能，特别是在支点效应自动化方面。MIST VR提供了一种训练腹腔镜手术心理运动技能的新方法。
