Claim 10:
11. An adapter assembly for interconnecting an end effector and a surgical device, the adapter assembly comprising:
a housing;
an outer tube extending distally from the housing along a longitudinal axis;
a distal end portion extending distally from the outer tube;
proximal and distal universal joints disposed within the distal end portion; and
a gimbal disposed around the distal universal joint, the gimbal configured to rotate and cause a corresponding directional movement of at least one of the proximal or distal universal joints to articulate the distal end portion relative to the outer tube,
wherein the distal end portion includes:
a first segment that is longitudinally fixed relative to the outer tube, the proximal universal joint rotatably coupled to the first segment;
a second segment having a proximal section disposed around the proximal universal joint and rotatably secured within the first segment, and a distal section disposed around the gimbal and the distal universal joint; and
a third segment disposed over the distal section of the second segment, the distal section of the second segment rotatable therein.
