Abstract

The present disclosure relates to a surgical instrument including an adapter assembly and an articulation surgical loading unit. The adapter assembly includes an articulation nut, an articulation link, and a drive belt operably coupled to a distal portion of the articulation link. The articulation link has a proximal end portion operably coupled to the articulation nut such that rotation of the articulation nut causes translation of the articulation link. The drive belt has a distal portion configured to be operably coupled to the proximal portion of the surgical loading unit such that movement of the drive belt articulates the surgical loading unit relative to the adapter assembly.
