Surgical stapling instruments with rotatable staple deployment arrangements

A surgical attachment assembly configured to be operably attached to a surgical robot, wherein said surgical attachment assembly comprises:

• a housing, comprising:
• an attachment portion configured to be mounted to the surgical robot, wherein said attachment portion comprises a perimeter defined by a first lateral side, a second lateral side, a third lateral side, and a fourth lateral side, wherein said first lateral side is positioned opposite said second lateral side, and wherein said third lateral side is positioned opposite said fourth lateral side;
• an interface defined within said perimeter;
• and
• a drive system configured to generate rotary motions, wherein said drive system comprises:
• a first rotatable drive input configured to be coupled with a first robot drive output of the surgical robot when said surgical attachment assembly is mounted to the surgical robot;
• a second rotatable drive input configured to be coupled with a second robot drive output of the surgical robot when said surgical attachment assembly is mounted to the surgical robot;
• a third rotatable drive input configured to be coupled with a third robot drive output of the surgical robot when said surgical attachment assembly is mounted to the surgical robot;
• and
• a fourth rotatable drive input configured to be coupled with a fourth robot drive output of the surgical robot when said surgical attachment assembly is mounted to the surgical robot, wherein said first rotatable drive input, said second rotatable drive input, said third rotatable drive input, and said fourth rotatable drive input are arranged within said perimeter and are openly accessible at said interface;
• an elongate shaft defining a longitudinal axis;
• a first jaw;
• a second jaw rotatable relative to said first jaw;
• a firing beam comprising a first cam configured to engage said first jaw and a second cam configured to engage said second jaw during a firing stroke;
• a translatable intermediate firing link positioned proximally with respect to said firing beam;
• and
• an actuator operably interfacing with said first rotatable input drive, wherein said actuator is actuatable by a pulling force in response to a rotation of said first rotatable drive input, wherein said actuator is configured to convert the pulling force to a distal firing motion of said firing beam, and wherein said translatable intermediate firing link transmits the distal firing motion from said actuator to said firing beam.

A robotic surgical stapler, comprising:

• a housing comprising a drive system configured to transmit rotary motions, wherein said drive system comprises a plurality of motor-driven rotary inputs, and wherein said plurality of motor-driven rotary inputs comprises a firing drive rotary input;
• an elongate shaft extending from said housing;
• a first jaw;
• a second jaw rotatable relative to said first jaw;
• a firing beam movable distally toward a distal end of said first jaw and said second jaw, wherein said firing beam comprises a first cam configured to engage said first jaw and a second cam configured to engage said second jaw during a firing stroke;
• a firing link positioned proximally with respect to said firing beam;
• and
• a firing actuator operably interfacing with said firing drive rotary input, wherein said firing actuator is actuatable by a pulling force in response to a rotation of said firing drive rotary input, wherein said firing actuator is configured to convert the pulling force to a distal firing motion of said firing beam, wherein said firing link transmits the distal firing motion from said firing actuator to said firing beam, and wherein said firing actuator comprises an endless cable loop.
