  • Patent number: 12239317
    Abstract: A surgical stapling assembly is disclosed. The assembly can include a cartridge body having cavities defined therein forming a pattern of openings in the deck of the cartridge body. The pattern can include longitudinally-repeating clusters of cavity ends. The assembly can also include fasteners removably positioned in the cavities. The pattern of openings can comprise openings on a first side of the cartridge body comprising inner openings each defining an inner proximal-to-distal axis oriented parallel to the longitudinal axis, outer openings each defining an outer proximal-to-distal axis obliquely-oriented relative to the longitudinal axis at an outer angle, and intermediate openings each defining an intermediate proximal-to-distal axis obliquely-oriented relative to the longitudinal axis at an intermediate angle, wherein the intermediate angle is different than the outer angle.

  • Patent number: 12226099
    Abstract: A surgical stapler having an end effector, a firing drive electric motor, and a control circuit is disclosed. The firing drive electric motor is configured to actuate a staple firing stroke of the end effector. The control circuit can be configured to provide a pulse width modulated (PWM) electrical signal to the firing drive electric motor and adjust a duty cycle of the PWM electrical signal based at least in part on a speed of the staple firing stroke. The control circuit can further be configured to provide a pulse width modulated (PWM) electrical signal to the firing drive electric motor, adjust a duty cycle of the PWM electrical signal based at least in part on a target speed of a staple firing stroke, and lower the target speed in response to the duty cycle exceeding a safety threshold value.

  • Patent number: 9980777
    Abstract: An apparatus includes an interface assembly and a shaft assembly. The interface assembly is configured for use with a robotic system and includes a first drive assembly and a mounting plate. The mounting plate includes an opening. The first drive assembly is positioned within the opening such that the first drive assembly is laterally translatable within the opening from a first position to a second position. The shaft assembly is removably coupled with the interface assembly. The shaft assembly includes an end effector and a first coupling feature. The first drive assembly of the interface assembly actuates the end effector of the shaft assembly. The first coupling feature is longitudinally aligned with the first drive assembly. The first drive assembly engages the first coupling feature of the shaft assembly when the first drive assembly is laterally translated from the first position to the second position.
