HEAD-MOUNTED VIDEO MONITOR FOR GLOBAL VISUAL ACCESS IN MINI-INVASIVE SURGERY - AN INITIAL REPORT

Video-assisted technology for minimally in invasive surgery uses the c oaxial approach (working field between surgeon and video monitor), Com plex procedures and two-team approaches disrupt this relationship caus ing paradoxic motion. In an effort to obviate these issues, a head-mou nted monitor display has been used by the surgeon in 74 of these compl ex operative procedures, The head-mounted display (HMD) eliminates the negative effects of yaw, roll, and pitch - each of which is detriment al to the performance of complex operative procedures. There has been no visual strain or ocular fatigue observed, In contrast. the HMD allo wed increased concentration without subjective muscle strain for as lo ng as 640 mins. The authors conclude that the HMD improves efficiency in complex procedures Increases safety, diminishes cost, and allows op timum visualization of the operative field by the sur eon and assistan ts in congested operating-room environments.
