An apparatus for controlling an end-effector assembly is provided. The apparatus includes a elongated element configured to engage the end-effector assembly and a drive assembly. A first motion transfer mechanism is disposed at an end of the elongated element. The first motion transfer mechanism is configured to transfer a rotational motion of the elongated element to a motion of the end-effector assembly. A second motion transfer mechanism is disposed at the second end of the elongated element. The second motion transfer mechanism is configured to transfer a motion of the drive assembly to the rotational motion of the elongated element.

Apparatus and method for controlling an end-effector assembly

An apparatus for controlling an end-effector assembly having a first working member and a second working member is provided. The apparatus includes a first set of at least one cable, a second set of at least one cable, a first pulley configured to guide the first set of at least one cable, a second pulley configured to guide the first set of at least one cable when the second pulley is in a first position, a third pulley configured to guide the second set of at least one cable, and a rotatable element rotatable about a first axis.

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.
