A Comparative Experimental Study Evaluating the Performance of Surgical Robots Aesop and Endosista

Abstract

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 laparoscopic surgery. The performance of these two robotic systems was examined for linear (upwards, downwards, diagonal), complex, and “in and out” movements using laparoscopic training boxes. Standard distances and tests were used for each system, and the time required to achieve each task was measured. The majority of the linear movements of the verbal and preprogrammed modes of Aesop were quicker than those of Endosista. Diagonal movements were significantly faster with the preprogrammed-mode Aesop. Complex or three-dimensional movements were also significantly faster with both modes of Aesop than with Endosista. Under the experimental conditions, Aesop, particularly in the preprogrammed mode, is quicker and more accurate than Endosista.
