The use of a telemanipulator with endoscopic instruments requires special training and surgical performance is associated with a learning curve. The aim of this study was to demonstrate the potential value of Haptic-Visual over Visual-Only passive Training in Telemanipulator-assisted surgery.
Two Telemanipulator consoles (da Vinci, Intuitive Surgical) were linked through an Application Interface (API) allowing the surgeon at the training console to passively follow the motions of the instructor (Haptic-Visual Learning group, hv). Both the trainee and the instructor shared the same 3D vision. Alternatively, subjects received only standard visual training (Visual-Only Learning group, v). Before starting the trial a standardized demonstration of tasks and the system was given for both groups. Participants (n=20 without previuos experience with telemanipulation per group) performed a set of various tasks in a randomized order. Study endpoints were time and accuracy required to perform the different task.
The first task, with moving items to appropriate locations showed no significant differences in the time to perform the task (mean: 2.43min [hv] vs. 3.04min [v]) but accuracy of performance (number of mistakes, number of trials before the task could be accomplished) was enlarged in the visual-only passive learning group with summary: 14.3 [v] vs. 2.4 [hv]. With more challenging tasks (cut off a round figure out off elastic material [cut] and performing double dot suture lines [sti]) the number of mistakes were significantly less in the hv group (summary: 7.6[cut] and 9.9[sti] compared to the v group (summary 16.8[cut] and 24.4[sti]). The time to perform the tasks decreased in the hv group with mean: 5.02min [cut] and 7.11min[sti] compared to the v group with mean: 6.42min[cut] and 9.02min[sti].
This study demonstrated the impact of haptic-visual passive learning in computer-assisted surgery.
