Introduction Laparoscopic ventral hernia repair (VHR) is associated with decreased morbidity and shorter length of stay (LOS) when compared to open VHR. Despite evidence of the benefits of laparoscopy, its utilization in VHR has lagged behind that of other complex surgical procedures. We hypothesized that utilization is further reduced in emergency cases. The aim of this study was to evaluate the...
Leonardo is a prototype interactive augmented reality system designed to aid a surgeon in port-placement prior to performing robot-assisted laparoscopic surgery. The system components consist of a computer, a projector, and a motion and color tracking device. The human-computer interface through which the surgeon interacts with the system is the patient's abdomen itself. Based on the parameters of...
Minimally invasive surgery uses optical cameras and special surgical tools in order to operate from an environment one step removed from the body cavity of interest to the surgeon. It has been suggested that constraints posed by this arrangement, in particular the lack of direct haptic feedback to the surgeon, may affect the surgeon's ability to identify tissues and accurately maneuver inside the...
