1. A surgical cutting and stapling instrument comprising:

  • at least one processor and operatively associated memory, the instrument configured to;

    store a parameter, wherein the parameter comprises a rate of average tissue pressure change;

    store an acceptable value for the parameter, wherein the acceptable value includes a predetermined threshold value for the rate of average tissue pressure change;

    store a first control measure associated with the parameter; and

    determine, in response to determining that a measured value of the rate of average tissue pressure change is equal to or greater than the predetermined threshold value, that a second control measure be identified,wherein the second control measure is associated with a closure rate of a first jaw and a second jaw of the instrument, and the second control measure comprises decreasing the closure rate during a closing phase based on a reference closing speed in response to determining that the measured value of the rate of average tissue pressure change is equal to or greater than the predetermined threshold value,wherein the second control measure is modified by setting forth a new acceptable value.
