COVER : Compact Oblique-Viewing Endoscope Robot for laparoscopic surgery

We developed a new laparoscopic manipulator to substitute for the human assistant, which utilizes the property of oblique viewing laparoscopes. Instead of panning around the fulcrum to move the laparoscopic field of view to left/right in the case of the "straight-viewing" laparoscope, only the scope cylinder of the "obliqueviewing" laparoscope attached to the manipulator rolls about its axis. By implementing this mechanism, we have developed more compact, simple, and easier laparoscope manipulator than ever. To evaluate the validity of this system, we conducted a laparoscopic surgery experiment in an in vivo environment. As conclusions, the proposed oblique-viewing endoscope manipulator could substitute for the human assistant during the operation.
