Chirurgie robotique : de l'apprentissage à l'application

Abstract : The huge expansion of minimally invasive robotic devices for surgery ask the question of the training of this new technology. Progress of robotic-assisted surgical techniques allows today mini- invasive surgery to be more accurate, providing benefits to surgeons and patients for complex surgical procedures. But, it resulted from an increasing need for training and development of new pedagogical strategies. Indeed, the surgeon has to master the telemanipulator and the procedure, which is different from a simple transposition of a laparoscopic skill. The first part of this work treats about historical development of minimal invasive surgery from laparoscopy to robotic surgery. We also develop the evolution of training program in surgery. Virtual simulators provide efficient tools for laparoscopy training. The second part of this work, study some possible solutions for robotic training. We assess the validity of a new robotic virtual simulator (dV-Trainer). We demonstrate the usefulness of this tool for the acquisition of the basic gesture for robotic surgery. Then, we evaluate the impact of a previous experience in micro-surgery on robotic training. We propose a prospective study comparing the surgical performance of micro-surgeons to that of general surgeons on a robotic simulator. We want to determine if this experience in micro-surgery could significantly improve the abilities and surgeons performance in the field of basic gesture in robotic surgery. The last part of the study also looks to the future. Currently, telesurgery need sophisticated dedicated technical resources. We want to develop procedures for clinical routine used. Therefore, we evaluate the impact of the delay on the surgical procedure. Also, reducing data volume allow decreasing latency. An appropriate solution to reduce the amount of data could be found by introducing lossy compression for the transmission using the well-known MPEG-2 and H-264 standards
