In one embodiment of the invention, a replaceable electrosurgical end effector cartridge is provided to couple to a mechanical wrist of a surgical instrument for a robotic surgical system. The replaceable electrosurgical end effector cartridge includes two pluggable end effectors and a pair of spring latches. The two end effectors are moveable end effectors having a jaw portion, an off-center portion, and a base portion in one embodiment. The replaceable electrosurgical end effector cartridge may further include a fastener to rotatably couple the end effectors together.
