1. An adapter assembly for selectively interconnecting a surgical loading unit that is configured to perform a function and a surgical device that is configured to actuate the surgical loading unit, the surgical loading unit including an axially translatable drive member, and the surgical device including a plurality of rotatable drive shafts, the adapter assembly comprising:
a housing configured and adapted for connection with the surgical device and to be in operative communication with each rotatable drive shaft of the plurality of rotatable drive shafts of the surgical device; an outer tube defining a longitudinal axis and having a proximal end supported by the housing and a distal end portion configured and adapted for connection with the surgical loading unit, the distal end portion in operative communication with the axially translatable drive member of the surgical loading unit; an articulation assembly including a gimbal supported in the distal end portion of the outer tube and a plurality of threaded sleeves supported in the housing, the plurality of threaded sleeves coupled to the gimbal by at least one cable; and a firing assembly including a firing shaft supported within the housing and the outer tube, the firing shaft including at least one universal joint, wherein rotation of at least one of the plurality of rotatable drive shafts of the surgical device translates at least two of the plurality of threaded sleeves to articulate the gimbal relative to the longitudinal axis of the outer tube with the at least one cable, and wherein articulation of the gimbal articulates the at least one universal joint of the firing shaft and the surgical loading unit about the distal end portion of the outer tube. |
