Claim 11:
12. An adapter assembly of a surgical instrument, the adapter assembly comprising:
an outer tube;
a surgical loading unit having a proximal end portion pivotably coupled to a distal end portion of the outer tube;
an articulation rod extending through the outer tube and having a proximal end portion configured to be operably coupled to a drive member, and a distal end portion, the articulation rod being configured to translate within the outer tube;
a spring disposed about the articulation rod, wherein the spring is configured to exert a proximally-oriented bias against the articulation rod;
an articulation link having a proximal end portion pivotably coupled to the distal end portion of the articulation rod, and a distal end portion configured to be pivotably coupled to a surgical loading unit to articulate the surgical loading unit relative to the outer tube in response to translation of the articulation rod;
a proximal pivot housing fixed to the distal end portion of the outer tube; and
a distal pivot housing fixed to a proximal end portion of the surgical loading unit, the distal pivot housing defining a proximally extending slot for receipt of the distal end portion of the articulation link.
