Abstract: In some embodiments, torque compensation in a clamping instrument includes control electronics obtaining an initial torque limit for the clamping instrument, adjusting the initial torque limit based on a temperature of a motor assembly used to operate the clamping instrument, and clamping the clamping instrument according to the adjusted torque limit. The adjusted torque limit corresponds to a maximum torque that may be applied by the clamping instrument to perform the clamping. In some embodiments, torque compensation in a stapling instrument includes control electronics obtaining an initial torque limit for the stapling instrument, adjusting the initial torque limit based on a number of times the stapling instrument has been fired, and firing the stapling instrument according to the adjusted torque limit. The adjusted torque limit corresponds to a maximum torque that may be applied by the stapling instrument to perform the firing.

Abstract: A method of controlling a surgical instrument comprising an end effector may comprise detecting a first signal indicating that an end effector component of a surgical instrument is positioned between a first position and a second position; and automatically controlling operation of the end effector component when a second signal is not detected within a predetermined delayed response time period after detecting the first signal, wherein the second signal indicates that the end effector component is in one of the first position or the second position.
