An electromechanical instrument, comprising: a handle housing supporting a plurality of drive connectors; a drive mechanism supported in the handle housing and configured to selectively rotate the plurality of drive connectors; an end effector supporting an axially translatable drive member; an adapter assembly selectively connectable between the handle housing and the end effector, the adapter assembly includes: an outer tube; an inner tube supported within the outer tube; a proximal drive shaft coupled to a first one of the plurality of drive connectors of the handle housing, the proximal drive shaft rotatable in response to rotation of the first one of the plurality of drive connectors; a distal drive shaft supported within the inner tube and operably coupled to the proximal drive shaft; a drive coupling nut threadably coupled to the distal drive shaft and supported within the inner tube such that inner tube prevents the drive coupling nut from rotating, the drive coupling nut slidably movable along the inner tube as the distal drive shaft rotates; and a drive tube coupled to the drive coupling nut and axially movable as the drive coupling nut slides along the inner tube, the drive tube operably coupled to the axially translatable drive member of the end effector. |
