触觉反馈已被证明有利于各种腹腔镜手术任务的性能。然而，在训练的早期阶段向新手学员提供触觉反馈可能会分散注意力。进行了对照实验，以探讨触觉反馈对复杂的腹腔镜缝合和打结任务的学习曲线的影响。假设受试者在使用支撑襻时比不使用支撑襻时表现更好，并且更早达到学习曲线的第一个平台。20名新手参加了18个一小时的培训课程。结果表明，在五个小时的训练后，有触觉的训练与没有触觉的训练没有显著差异。然而，那些通过触觉反馈学习的人在任务表现上更一致，学习曲线更短。因此，触觉反馈可以省略腹腔镜手术模拟器在早期培训，提供广泛的培训是可能的。
Haptic feedback has been shown to benefit performance in various laparoscopic surgery tasks. However, providing haptic feedback to novice trainees in the early stages of training may be distracting. A controlled experiment was conducted to investigate the effect of haptic feedback on the learning curve of a complex laparoscopic suturing and knot-tying task. It was hypothesized that subjects would perform better and reach the first plateau in the learning curve earlier with haptics than without. Twenty novices participated in eighteen one-hour training sessions. Results indicated that training with haptics was not significantly different from training without haptics after five hours of practice. However, those who learned with haptic feedback were more consistent in their task performance and had a shorter learning curve. Therefore, haptic feedback may be omitted in a laparoscopic surgical simulator in early training provided that extensive training is possible.
