1. A powered surgical cutting and stapling instrument comprising:
- at least one sensor to measure at least one parameter associated with the instrumentat least one processor; and
a memory operatively associated with the processor, the memory including machine executable instructions that when executed by the processor cause the processor to;
monitor the at least one sensor over a predetermined time period; and
determine a rate of change of the measured parameter.

Abstract
A powered surgical cutting and stapling instrument is disclosed. The instrument includes at least one sensor to measure at least one parameter associated with the instrument, at least one processor, and a memory operatively associated with the processor. The memory includes machine executable instructions that when executed by the processor cause the processor to monitor the at least one sensor over a predetermined time period and determine a rate of change of the measured parameter.

9. A powered surgical cutting and stapling instrument comprising:
-
an end effector comprising a first jaw member and a second jaw member, wherein at least one of the first and second jaw members is movable relative to the other jaw member, and wherein the at least one sensor is positioned on at least one of the first and second jaw members. a pressure sensor or strain gauge positioned in at least one of the first or second jaw members; at least one processor; a memory operatively associated with the processor, the memory including machine executable instructions that when executed by the processor cause the processor to; monitor the pressure applied to tissue grasped between the first and second jaw members; and determine a type of tissue grasped between the first and second jaw members based on the tissue pressure measurement. - View Dependent Claims (10, 11, 12)
