Robotic Surgery Overcomes Many of the Drawbacks of Conventional Laparoscopy

Evolution of Robotic Surgery

� NASA and the military : Conceptualized telesurgery to provide surgical expertise to remote locations

� Telesurgery “drove” first development of robotic surgery platforms… limited by bandwidth limitations

� Telepresence surgery: today’s modern robotic surgery

Evolution of Robotic Surgery

� AESOP (Computer Motion, Goleta, CA): first robotic-assisted surgical technology: robot only controlled camera

� Zeus Robotic System : (Computer Motion, Goleta, CA): the first robotic system to provide instrument control� 2 dimensional image

� Intuitive Surgical (Sunnyvale, CA) purchased Computer Motion; Zeus Robotic System; abandoned in favor of da Vinci® Robotic Surgical System
