Preparedness in robotically assisted interventions.

For many years, robots have been used in manufacturing to perform a variety of delicate tasks. Their use is now being generalized to other fields, such as biology, domestic applications, and especially medicine, in which they are poised to make a significant contribution. This evolution comes from the progress made in the field of robotics and from recent changes in medical and surgical techniques, namely, developments in medical imaging and a new desire for minimally invasive interventions. This emerging combination of high-precision robotic manipulators, new medical diagnostic techniques, and efficient minimally invasive surgery has not yet been perfected. After a brief discussion of state-of-the-art robotic systems used in urology, this article discusses new challenges presented by robotic minimally invasive surgery. A computer-integrated approach aimed at increasing the efficiency of such interventions through better preparedness is presented. This approach is illustrated by a case study in human nephrectomy and a cardiac animal experiment.
