Abstract
A robotic system for use in Minimally Invasive Surgery (MIS) is provided that, in various aspects of this specification, comprises at least one elongated shaft known as the robotic arm. In certain aspects, the robotic arm is provided with an independent roll wrist mechanism, which can allow for imparting the roll motion to the end effectors while mitigating or potentially eliminating the need of rotating the entire robotic arm, thus ensuring independent movement of end effectors. The independent movement of the end effectors sweeps a considerably smaller conical volume, as compared to that swept by the entire robotic arm, thereby reducing the likelihood of collisions with neighboring tissues or organs.
