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.
