| Research Abstract |
This study aims to realize a three-dimensional (3D) endoscope with multiple degrees of freedom (DOFs) and a variable convergence angle mechanism for laparoscopic surgery with a narrow operation field. This 3D endoscope provides an optimal 3D image view with a feeling of natural depth by wide convergence and multiple DOFs. We developed a tip-lateral Full HD CMOS image sensor 3D endoscope having a bending mechanism with 1 DOF and a variable convergence angle mechanism. Using this device, we could provide a 3D image with a feeling of natural depth and a wide range without a sense of incongruity.
