Background: The aim was to develop a new type of robotic wide-angle view endoscope that does not require rotation or bending of the endoscope to move the field of view. This endoscope allows the surgeon to make extensive observations in a small space. It is safe because it avoids the possibility of hitting organs accidentally. Methods: The system consists of an endoscope with a zoom facility and two wedge prisms at the tip. Each prism is set on its own sleeve at the end of the endoscope, and both prisms rotate independently about the axis of the endoscope. Results: In the in vivo experiment, the high quality of the image was confirmed, and almost whole liver could be observed without the observer moving the endoscope itself. Conclusions: This system provides safe robotic endoscopic surgery because of the high quality of the image. It has great significance for future clinical use.
