Overview

In this research, a stereoscopic endoscope that can obtain depth information in real time is applied for development of a new autonomous laparoscope manipulation robot. (a) First of all, an algorithm for real-time visual tracking of surgical instruments is developed. (b) The surgeon’s upper limb and the robotic manipulator that holds the stereoscopic endoscope are then regarded as an integrated hand-eye system, and the goodness of the field of view (FOV) is estimated during surgery based on the surgeon’s joint angle information from ergonomic sensors and the depth information of the instruments tracked in endoscopic images. A new methodology of autonomous endoscope manipulation for assistant-free robotic laparoscopic surgery is finally established.
