Abstract
An articulation assembly for use with a surgical device includes a drive bar, a locking pin, a drive gear, and a yoke. The drive bar includes a base and a stem extending therefrom. The base includes first teeth. The locking pin engages the first teeth of the drive bar. The drive gear is operatively coupled to the drive bar. The drive gear includes second teeth defining a gap between adjacent second teeth. The gap is configured to receive a portion of the locking pin. The yoke is operatively coupled to the drive gear such that rotation of the drive gear causes axial displacement of the yoke. Rotation of the drive bar transitions the locking pin from a locked state to an unlocked state and rotates the drive gear when the locking pin is in the unlocked state such that the yoke is axially displaced.
