a housing including at least one actuator configured to receive an input for remotely activating an end effector of an articulating surgical instrument; and
a driving assembly disposed within the housing, the driving assembly including a spring configured to be compressed in response to the least one actuator receiving the input to cause a drive wire to activate the end effector, the driving assembly including a compression tab and a cam piston configured to move the compression tab proximally to compress the spring, wherein the spring stretches as a result of the end effector being disposed in an articulated position thereby placing the drive wire under increased tension as a result of a spring force on the stretched spring.
