Abstract
A method for powered surgical stapling instrument rotation adjustment includes measuring a change in position of a first motor shaft of the surgical stapling instrument relative to a stored rotation verification position of the first motor shaft resulting from manual rotation of an adapter assembly of the surgical stapling instrument in relation to a handle assembly of the surgical stapling instrument, determining a distance traveled by a first drive assembly of the adapter assembly of the surgical stapling instrument resulting from the change in position of the first motor shaft, comparing the determined distance traveled to a first stored rotation verification position of the first motor shaft, determining if the compared distance falls into a predetermined acceptable range of rotation positions, and adjusting the position of the drive shaft if the compared distance is not within the predetermined range.
