This paper deals with the development of a new generation of augmented laparoscopy system. We propose to equip a traditional endoscope, or a robotic endoscope holder, with a miniature stereovision device. The system includes two miniature high resolution CMOS cameras mounted around the endoscope as a pair of glasses that provides a global view of the abdominal cavity completing the traditional view. Each camera can reach a frame rate of 30 images/second with a resolution of 1600 _ 1200 pixels. A deployment, fixation and rapid extraction system of the proposed device through the trocar was designed and validated through preclinical experiments (testbench and human cadaver). The main benefit of the proposed system in the minimally invasive surgery domain is to provide simultaneously local/global views, and with perspectives in 3D reconstruction of the organ being treated.
