Gaining access to the peritoneal cavity through a natural orifice is potentially the next paradigm shift in minimally invasive surgery. Natural Orifice Translumenal Endoscopic Surgery (NOTES) provides distinct patient advantages, but is surgically challenging. Access to the peritoneal cavity is limited by the size and complex geometry of the natural lumen,(More)
Minimally invasive surgery (MIS) reduces patient trauma and shortens recovery time, but also limits the dexterity of the surgeon because degrees of freedom are lost due to the fulcrum effect of the entry incisions. Visual feedback is also limited by the laparoscope, which typically provides two-dimensional feedback and is constrained by the entry incision.(More)
robotic systems have a great impact on the application of laparoscopic surgeries in the operating room. The advent of externally operated surgical robots has prompted the first significant shift in general laparoscopic surgeries. Miniature in vivo robots that can be completely inserted in to the abdomen are also being studied to reduce patient trauma.(More)
