Abstract: A software for driving a motor in a powered surgical stapler can include driving a firing assembly through an end effector during a firing stroke, detecting when the firing assembly enters a final distance of the firing stroke, decreasing a target speed of the firing assembly for the final distance, and impacting a distal portion of the firing assembly to the end effector. The firing assembly may be intentionally driven into the end effector. The software may cease driving the firing assembly in response to detection of the impact. The reduction in target speed can be accomplished by adjusting a motor drive signal to a motor driving the firing assembly.

Abstract: A method of driving a motor in a powered surgical stapler can include a pausing monitoring process that may be effective to improve staple form and/or increase localized compression of tissue. The pausing monitoring process monitors firing speed of a firing bar driving by the motor and pauses the motor when the firing speed passes a speed error threshold. Before pausing the motor, the pausing monitoring process may also require that a pulse width modulated (PWM) electrical signal driving the motor has a duty cycle over a duty cycle threshold while the firing speed is beyond the speed error. The pausing monitoring process may force the firing bar through a predetermined distance immediately after pausing. The pausing monitoring process may be limited in the number of pauses that can be taken during a firing stroke.
