Abstract

A drive assembly for an adapter assembly of a surgical device includes an input shaft, a middle shaft, and an output shaft. The input shaft includes a proximal portion configured for operable engagement with a drive member of a handle assembly and a distal portion including a first castellated portion. The middle shaft includes a proximal portion having a first lobed portion in operable engagement with the first castellated portion of the input shaft, and a distal portion having a second lobed portion. The output shaft includes a proximal portion having a second castellated portion in operable engagement with the second lobed portion.
