Abstract
A method of operating a surgical stapler includes advancing a knife assembly at a first velocity until a predetermined force is detected, advancing the knife assembly at a second velocity when the predetermined force is detected, the second velocity being less than the first velocity, and continuing to advance the knife assembly at the second velocity until the knife assembly travels a cutting stroke distance.
