Abstract: A powered handle for a surgical stapler has a drive system including an electric motor. The powered handle includes a shaft recognition mechanism such that when a reload shaft for use with the surgical stapler is installed, a control system can actuate the drive system with the recognized shaft. The powered handle further comprises a LED light ring driven by a light control scheme to display a handle status. The control system also includes a startup module to assess hardware and control system performance before use. The startup module assesses different criteria depending on whether the handle is new, previously used, or previously reset. The control system of the powered handle further includes a lockout module configured to identify when a lockout has been encountered. The lockout module applies different criteria depending on whether the motor is operating at a maximum speed state or less than a maximum speed state.

Abstract: The present disclosure relates to systems, devices, and subsystems for robotic surgeries. The surgical instrument is a robotic attachment that includes an articulation subsystem comprising a rotatable shaft, a distal channel retainer coupled to an end effector that is pivotable about an articulation pivot point, an articulation bushing slidable between a proximal position and a distal position, an articulation rod extending distally from the articulation bushing and coupled at a distal end to the distal channel retainer; and a rack movable with respect to the longitudinal axis of the rotatable shaft. Movement of the rack with respect to the longitudinal axis imparts an axial force onto the articulation bushing moving the articulation bushing between the proximal position and the distal position. Movement of the articulation bushing between the distal position and the proximal position actuates the articulation rod causing the distal channel retainer to pivot about the articulation pivot point.

Abstract: Systems and subsystems for articulating an end effector of a stapler are disclosed.

The surgical instrument includes an articulation subsystem that moves independently of other subsystems that are operable independently of each other.

Abstract: A powered handle for a surgical stapler can have a drive system including an electric motor. The powered handle can include a manual return mechanism. The powered handle can also include a retention mechanism to prevent unintentional movement of drivetrain components upon actuation of the manual return mechanism. For example, the retention mechanism can apply a direction-dependent frictional force on an actuation shaft of the handle assembly to prevent unintentional movement of the actuation shaft towards a distal end of the handle assembly. The retention mechanism can include a featherboard-like configuration with a plurality of ribs oriented transversely to the actuation shaft to restrict movement of the actuation shaft in one direction while allowing movement of the shaft in the opposite direction.

Abstract: A tissue sensor is used with a surgical stapling instrument to sense tissue characteristics and to provide accurate tissue measurements. The tissue sensor includes a flexible substrate, a sensor array, and a controller. The flexible substrate is disposed between the tissue and the surgical stapler. The sensor array comprises sensors disposed on the flexible substrate, senses a parameter, and generates a signal indicative thereof in response to a clamping force that is applied by the surgical stapler to clamp the tissue and the tissue sensor together. The controller is disposed in or on the flexible substrate and is configured to receive the signal from the sensor array, process the signal to determine a measurement of the parameter based on the processed signal, and provide an indication of the measurement of the parameter to a user of the surgical stapler.

More specifically, the present disclosure relates to systems, devices, and subsystems for attachments for robotic surgeries. The surgical instrument is a robotic attachment that includes a closure subsystem for a surgical instrument comprising a first closure input puck engageable with a first closure robotic output, a cam gear rotatably engaged with the first closure input puck, and a yoke pin coupled to a closure tube and movable from a first position to a second position in response to a rotation of the cam gear. Movement of the yoke pin from the first position to the second position translates the closure tube distally onto an anvil ramp of an anvil.

Abstract: Systems and subsystems for using a robotic instrument are disclosed. The method includes engaging a first closure input puck with a first closure robotic output. The method includes rotating the first closure robotic output to cause the first closure input puck to rotate. The method includes rotating a cam gear via the rotation of the first closure input puck. Rotation of the cam gear causes a yoke pin to track through a cam track in the cam gear, and the yoke pin is coupled to a closure tube. Tracking of the yoke pin through the cam track causes the yoke pin to translate from a first position to a second position, thereby translating the closure tube.
