Freehand is a modification of Prosurgics EndoAssist. The Freehand is intended for use in minimally invasive laparoscopic, thoracoscopic, urological, gynecological and cardiac surgery where a rigid laparoscope/endoscope is intended for use, and allows the surgeon directly to control movements of a rigid endoscope by head movements. Changes that have been made are to provide simpler control mechanisms that should result in greater reliability, as well as several convenience features. From the surgeon's point of view, the two devices are the same as far as their operation and functions are concerned.
