An end effector for use and connection to a robot arm of a robotic surgical system, wherein the end effector is controlled and/or articulated by at least one cable extending from a respective motor of a control device of the robot surgical system, is provided. The end effector includes a jaw assembly defining a longitudinal axis and including a pair of jaws. Each jaw includes a proximal portion pivotally connected to the distal hub assembly； and a distal portion extending distally of the proximal portion thereof. The end effector additionally includes an actuation cable having a distal end operatively connected to the pair of jaws and a proximal end operatively connected to the at least one motor. In use, axial translation of the actuation cable results in one of an opening and a closing of the jaw assembly.
