Abstract
The benefits of haptic feedback in laparoscopic surgery training simulators is a topic of debate in the literature. It is hypothesized that novice surgeons may not benefit from the haptic information, especially during the initial phase of learning a new task. Therefore, providing haptic feedback to novice trainees in the early stage of training may be distracting and detrimental to learning. The ProMIS and the MIST-VR surgical simulators were used to represent conditions with and without haptic feedback, respectively. Twenty novice subjects (10 per simulator) were trained to perform suturing and knot-tying and practiced the tasks over eighteen one-hour sessions. At the end of the 3-week training period, subjects performed equally fast but more consistently with haptics (ProMIS) than without (MIST-VR). Subjects showed slightly higher learning rate and reached the first plateau of the learning curve earlier with haptic feedback. In general, learning with haptic feedback was significantly better than without haptic feedback for a laparoscopic suturing and knot-tying task, but only in the first 5 hours of training.
