The present disclosure relates to electromechanical surgical systemsconfigured for usewith removable disposable loading units and/or single use loading units forclamping, cuttingand/or stapling tissue. A force transmitting assembly of surgical instrumenttransmits a rotationof a rotatable drive member of the surgical instrument to the rotationreceiving member of theend effector. A distal neck assembly of the surgical instrument includes atleast one gear systemconfigured to convert a rotational input of the rotatable drive member into atleast two outputforces to the end effector； and an articulating neck assembly interconnectingthe tubular bodyand the distal neck housing. The articulating neck assembly is configured toenable off-axisarticulation of the distal neck assembly. The rotatable drive member extendsthrough thearticulating neck assembly.
