Abstract:
A transabdominal magnetic anchoring and guidance system (MAGS) deploys multiple instruments through a single 15-mm diameter, transabdominal trocar. These instruments are positioned in the peritoneal cavity and controlled by externally placed magnets to reduce the need for multiple transabdominal trocars. To assess the feasibility of MAGS technology in a single keyhole, complex laparoscopic procedure, nonsurvival porcine nephrectomies were completed without complications via a single 15-mm transumbilical trocar using a prototype MAGS camera and a magnetically anchored, robotic arm cauterizer.
