1. An end effector assembly of a robotic surgical instrument, the end effector assembly comprising:
a clevis having a proximal end configured to attach to a shaft assembly of the robotic surgical instrument, the clevis including a first side wall, an upper wall having a cut-out, and a second side wall opposite the first side wall and defining a linear slot;
a first jaw member including a distal body portion, and a proximal flange portion extending proximally from the distal body portion, the proximal flange portion configured to move within the cut-out, the proximal flange portion defining an angled cam slot configured for receipt of a cam pin, the cam pin configured to move longitudinally through the angled cam slot defined by the proximal flange portion and the linear slot defined by the second side wall; and
a second jaw member including a distal body portion, and at least one proximal flange portion extending proximally from the distal body portion of the second jaw member and received between the first and second side walls, wherein the proximal flange portion of the first jaw member and the at least one proximal flange portion of the second jaw member are pinned to each other such that at least one of the first or second jaw members is configured to pivot relative to the other between a closed state in which the first and second jaw members are closer to one another, and an open state in which the first and second jaw members are further apart from one another.
