The study investigated whether 3D vision and haptic feedback in combination in a virtual reality environment leads to more efficient learning of laparoscopic skills in novices.
Twenty novices were allocated to two groups. All completed a training course in the LapSim virtual reality trainer consisting of four tasks: 'instrument navigation', 'grasping', 'fine dissection' and 'suturing'. The study group performed with haptic feedback and 3D vision and the control group without. Before and after the LapSim course, the participants' metrics were recorded when tying a laparoscopic knot in the 2D video box trainer Simball Box.
The study group completed the training course in 146 (100-291) minutes compared to 215 (175-489) minutes in the control group (p = .002). The number of attempts to reach proficiency was significantly lower. The study group had significantly faster learning of skills in three out of four individual tasks; instrument navigation, grasping and suturing. Using the Simball Box, no difference in laparoscopic knot tying after the LapSim course was noted when comparing the groups.
Laparoscopic training in virtual reality with 3D vision and haptic feedback made training more time efficient and did not negatively affect later video box-performance in 2D. [Formula: see text].
本研究调查了虚拟现实环境中3D视觉与触觉反馈相结合是否能使新手更有效地学习腹腔镜技能。
20名新手被分为两组。所有人都在LapSim虚拟现实训练器中完成了一个培训课程，该课程由四项任务组成：“器械导航”“抓持”“精细解剖”和“缝合”。研究组在有触觉反馈和3D视觉的条件下进行训练，而对照组则没有。在LapSim课程前后，记录参与者在2D视频盒训练器Simball Box中打腹腔镜结时的各项指标。
研究组完成培训课程用时146（100 - 291）分钟，而对照组用时215（175 - 489）分钟（p = 0.002）。达到熟练水平所需的尝试次数显著更少。研究组在四项单独任务中的三项——器械导航、抓持和缝合中，技能学习速度明显更快。使用Simball Box进行比较时，在LapSim课程后两组在腹腔镜结打结方面未发现差异。
在虚拟现实中进行的具有3D视觉和触觉反馈的腹腔镜训练使训练更具时间效率，并且对之后在2D视频盒中的操作表现没有负面影响。[公式：见正文]
