1. A surgical device, comprising:
a handle portion;
an elongate shaft extending distally from the handle portion;
an outer sleeve having a plurality of radially-extending slots formed therein;
an inner guide disposed within the outer sleeve;
a first articulation mechanism;
a second articulation mechanism;
an end effector configured to engage tissue and to be articulated relative to the elongate shaft;
wherein the outer sleeve and the inner guide cooperate to define a first longitudinal channel, in which the first articulation mechanism extends, and a second longitudinal channel, in which the second articulation mechanism extends; and
movement of the first articulation mechanism within the first longitudinal channel and movement of second articulation mechanism within the second longitudinal channel are configured to cooperate to cause the articulation of the end effector relative to the elongate shaft.
