  • Publication number: 20230051361
    Abstract: A method of operating a robotically controlled surgical instrument that includes an end effector, a driving assembly, and a lockout, the method includes inhibiting actuation of the driving assembly when the lockout is in a locked configuration in response to an unspent staple cartridge being absent from a first jaw of the end effector. The method also includes inserting the unspent staple cartridge into the first jaw of the end effector to switch the lockout to an unlocked configuration. The method also includes actuating the driving assembly to pivot the first jaw, which includes the staple cartridge, toward a second jaw of the end effector to at least one of staple or cut tissue with the end effector when the lockout is in the unlocked configuration.

    Abstract: A surgical stapling instrument includes a shaft assembly and an end effector. The end effector includes a first jaw having an anvil, and a second jaw. The instrument also includes a stapling assembly supported by the second jaw and including a plurality of staples, a staple actuator, and a driver assembly. The driver assembly includes a laterally-opposed pair of distal drivers that receive respective staples, a proximal driver that receives a respective staple, and a cam surface. The staple actuator is configured to engage the cam surface during distal translation of the staple actuator to drive the respective staples into contact with the anvil. The staple actuator and the cam surface are configured such that, when the respective staples contact the anvil, the engagement between the staple actuator and the cam surface is centered at a location along the cam surface distal of a centroid of the first driver assembly.

  • Publication number: 20230045893
    Abstract: A surgical instrument includes a body, a shaft assembly, an end effector, a stapling assembly, and a restriction feature. The shaft assembly extends distally from the body. The end effector being on a distal end of the shaft assembly and incudes a first second jaw. The stapling assembly is supported by one of the first jaw or the second jaw. The stapling assembly includes a wedge sled. The wedge sled is configured to move relative to the one of the first jaw or the second jaw to drive movement of one or more staples. The restriction feature is configured to releasably hold the wedge sled in a predetermined position within the stapling assembly while the stapling assembly is in a pre-fired configuration. At least a portion of the restriction feature is configured to respond to movement of the edge sled to release the restriction feature from the wedge sled.

  • Publication number: 20230051222
    Abstract: A surgical stapling instrument includes a shaft assembly and an end effector. The end effector includes a first jaw having an anvil, a second jaw configured to removably receive a staple cartridge, and a driving assembly translatable distally through the second jaw for pivoting the second jaw toward the first jaw to clamp tissue between the first jaw and the second jaw. The instrument also includes a lockout mechanism configured to transition between a first state in which the lockout mechanism prevents distal translation of the driving assembly through the second jaw, and a second state in which the lockout mechanism permits distal translation of the driving assembly through the second jaw. The lockout mechanism is configured to transition from the first state to the second state when the staple cartridge is removably received by the second jaw.

  • Publication number: 20220387026
    Abstract: A surgical instrument system is disclosed which comprises a distal end and a staple cartridge assembly comprising staples removably stored therein. The instrument system further comprises a firing drive including an electric motor and a firing member operably couplable with the electric motor. The electric motor is operable to advance the firing member toward the distal end during a staple firing stroke to eject the staples from the staple cartridge. The electric motor is operable to retract the firing member away from the distal end during a retraction stroke. The surgical instrument system further comprises a manually-operated bailout mechanism operable to perform the retraction stroke in lieu of the electric motor, a controller, and a display in communication with the controller. The controller is configured to display the progress of the retraction stroke when the firing member is being manually retracted by the bailout mechanism.
