    Abstract

    Background Advanced flexible endoscopes and instruments with multiple degrees of freedom enable physicians to perform challenging procedures such as the removal of large sections of mucosal tissue. However, these advanced endoscopes are difficult to control and require several physicians to cooperate. Methods In this article, we present a robotic system that allows the physi- cian to control an instrument in an intuitive way, using a haptic device. Perfor- mance with the robotic and conventional control methods were compared in a human subjects experiment. Subjects used both methods to tap a series of tar- gets. They performed four trials while looking at the endoscopic monitor, and two trials while looking at the instrument directly. Results Subjects were significantly faster using the robotic method, 54 s vs 164 s. Their performance in the second trial was significantly improved with respect to the first trial. Conclusions This study provides evidence that the robotic control method can be implemented to improve the performance of physicians using advanced flexible endoscopes.
