Claim of US Patent No. 11,109,860

1. A surgical end effector configured for interchangeable use in connection with a hand-held surgical system and a robotically-controlled surgical system, said surgical end effector comprising:a cartridge mounting portion configured to operably support a surgical staple cartridge therein;
a firing member supported for movable travel within said cartridge mounting portion upon applications of rotary drive motions thereto;
an anvil movably supported on said cartridge mounting portion for selective travel between an open position and a closed position; and
an end effector shaft assembly configured to be interchangeably attachable to a proximal shaft portion protruding from one of the hand-held surgical system or the robotically-controlled surgical system such that said surgical end effector is selectively articulatable relative to the proximal shaft portion about multiple axes that are transverse to a shaft axis that is defined by the proximal shaft portion, wherein said end effector shaft assembly comprises:an end effector drive shaft assembly that is configured to receive said rotary drive motions from the proximal shaft portion and apply said rotary drive motions to said firing member; and
an end effector coupler portion comprising a distal flanged joint arrangement operably attachable to a proximal flanged joint arrangement on either one of the proximal shaft portions protruding from the hand-held surgical system or the robotically-controlled surgical system by engaging said distal flanged joint arrangement with the proximal flanged joint arrangement in a first installation direction that is transverse to the shaft axis and without applying a rotary installation motion to either of the proximal flanged joint arrangement or said distal flanged joint arrangement.
