A comparative experimental study evaluating the performance of surgical robots Aesop and Endosista

The aim of this study was to experimentally assess and compare the accuracy of the surgical robots Aesop and Endosista as camera holders for use in la paroscopic surgery. The performance of these two robotic systems was examin ed for linear (upwards, downwards, diagonal), complex, and "in and out" mov ements using laparoscopic training boxes. Standard distances and tests were used for each system, and the time required to achieve each task was measu red. The majority of the linear movements of the verbal and preprogrammed m odes of Aesop were quicker than those of Endosista. Diagonal movements were significantly faster with the preprogrammed mode Aesop. Complex or three-d imensional movements were also significantly faster with both modes of Aeso p than with Endosista. Under the experimental conditions, Aesop, particular ly in the preprogrammed mode, is quicker and more accurate than Endosista.
