The aim of this study was to evaluate four training programmes intended to help laparoscopic surgeons automate to the "fulcrum effect".
A total of 32 participants (16 men, 16 women), were randomly assigned to one of four different image-viewing conditions: full binocular, y-axis inverted, normal laparoscopic and randomly alternating (between y-axis-inverted and normal laparoscopic). The subjects were requested to perform 10 trials of a simple laparoscopic cutting task, each lasting 2 minutes. Each then completed a 2-minute test under normal laparoscopic imaging conditions.
In the final test trial, participants who trained under the randomly alternating imaging conditions (y-axis inverted and normal laparoscopic) performed significantly better than those from the other groups.
Training under a randomly alternating viewing condition helps laparoscopic trainees automate to the "fulcrum effect" faster.
本研究旨在评估四项旨在帮助腹腔镜外科医生实现“支点效应”自动化的培训方案。
共有32名参与者（16名男性，16名女性）被随机分配到四种不同的图像观察条件之一：全双眼视觉、y轴倒置、正常腹腔镜视觉以及随机交替（y轴倒置和正常腹腔镜视觉之间交替）。要求受试者进行10次简单的腹腔镜切割任务试验，每次持续2分钟。然后每个人在正常腹腔镜成像条件下完成一次2分钟的测试。
在最终测试试验中，在随机交替成像条件（y轴倒置和正常腹腔镜视觉）下训练的参与者表现明显优于其他组的参与者。
在随机交替观察条件下进行训练有助于腹腔镜学员更快地实现“支点效应”自动化。
