Abstract
The added precision and steadiness of a robotically held camera enables the performance of more complex procedures laparoscopically. In contrast to typical laparoscope holders, the modified lightweight robotic endoscope, the ViKY system is particularly compact, simple to set up and use, and occupies no floor space. Ease and safety of setup was confirmed in a porcine model and several common general surgical procedures were performed. The sterilizable endoscope manipulator is sufficiently small to be placed directly on the operating room table without interfering with other handheld instruments during minimally invasive surgery. The endoscope manipulator and its user interface were tested and evaluated by several surgeons during a series of 5 minimally invasive surgical training procedures in a porcine model. The endoscope manipulator described has been shown to be a practical device with performance and functionality equivalent to those of commercially available models, yet with greatly reduced size, weight, and cost.
