Patent number: 11992209Abstract: A surgical instrument includes a shaft assembly, an end effector, a driving assembly, at least one motor, and a motor controller. The at least one motor is configured to actuate the driving assembly to deploy staples. The motor controller is in communication with the motor. The motor controller is configured to determine whether values of first and second trigger variables exceed predetermined thresholds. The motor controller is configured to modify at least one motor control parameter in response to determining that the values of the first and second trigger variables exceed the predetermined thresholds. The motor control parameters include a motion profile instituted by the motor controller for the motor, a waiting period during which power to the motor is reduced or stopped, or the predetermined threshold relating to current or force for proximal retraction to be different from the predetermined threshold relating to current or force for distal advancement.Type: GrantFiled: August 16, 2021Date of Patent: May 28, 2024Assignee: Cilag GmbH InternationalInventors: Frederick E. Shelton, IV, Kevin M. Fiebig, Shane R. Adams, Nicholas J. Ross, Matthew D. Cowperthwait, Curtis A. Maples

Patent number: 11992210Abstract: A surgical stapling instrument includes a shaft assembly, an end effector at a distal end of the shaft assembly and having a first jaw with an anvil and a second jaw operable to cooperate with the first jaw to clamp tissue, and a cartridge inserted into the second jaw. The cartridge includes staples, a movable member translatable distally during a firing stroke to discharge the staples into tissue, a first sensor assembly configured to monitor a first condition of the cartridge, and a second sensor assembly configured to monitor a second condition of the cartridge. A first processor is coupled with the first and second sensor assemblies and is configured to receive first and second signals from the sensor assemblies, respectively, where each signal is indicative of the respective condition of the cartridge. The first processor is configured to selectively permit or restrict the firing stroke based upon the signals.Type: GrantFiled: August 16, 2021Date of Patent: May 28, 2024Assignee: Cilag GmbH InternationalInventors: Frederick E.

Publication number: 20240108335Abstract: A surgical instrument is disclosed including an end effector configurable between an open state and a clamped state, a firing member movable from an unfired position toward a fired position during a firing stroke, a manually-driveable closure system, a motor-powered firing system, and a control system. The motor-powered firing system is configured to drive the firing member through the firing stroke. The control system is configured to detect, at a first time point, the end effector reaching the clamped state with the manually-driveable closure system, detect, at a second time point, the actuation of the motor-powered firing system, set a firing motion parameter of the motor-powered firing system based on an elapsed time from the first time point to the second time point, and drive the firing member through the firing stroke with the motor-powered firing system using the firing motion parameter.Type: ApplicationFiled: September 30, 2022Publication date: April 4, 2024Inventors: Frederick E. Shelton, IV, Shane R. Adams, Taylor W. Aronhalt, Nicholas J. Ross, Matthew D. Cowperthwait

Publication number: 20240108340Abstract: A surgical instrument system comprising a motor system and a control circuit is disclosed. The motor system comprises a motor and a drive train movable by the motor to actuate a firing member through a staple firing stroke. The control circuit is coupled to the motor, wherein, during the staple firing stroke, the control circuit is configured to perform a first sensory action to determine if a speed of the motor can be increased to a first target speed, monitor a result of the first sensory action, adjust a parameter of a subsequent sensory action based on the monitored result of the first sensory action, and perform the subsequent sensory action with the adjusted parameter.Type: ApplicationFiled: September 30, 2022Publication date: April 4, 2024Inventors: Frederick E. Shelton, IV, Jason L. Harris, Kevin M. Fiebig, Matthew D. Cowperthwait, Nicholas J. Ross, Shane R. Adams

Publication number: 20240108338Abstract: A surgical stapling system includes a motor, a gear reducer assembly, a drive train, and a motor controller. A method of controlling the motor includes applying a first signal to the motor, receiving drive train operational data, comparing the drive train data to baseline data, and applying a signal having a different shape than the first signal to the motor. A method of characterizing the motor includes transmitting a perturbation signal, receiving motor function parameters, determining stapler system characteristics, and adjusting a controller function. A method of controlling a stepper motor includes applying a signal to the stepper motor, receiving stepper motor operational data, comparing the data to baseline data, and adjusting the signal. Another method of controlling the motor includes receiving motor rotational data, receiving gear rotation data, calculating a mechanical transfer function, determining non-idealities of the stapling system, and modifying a control signal based on the non-idealities.Type: ApplicationFiled: September 30, 2022Publication date: April 4, 2024Inventors: Frederick E.
