Abstract
A surgical instrument that comprises an end effector comprising a first jaw, a second jaw, a staple cartridge, and at least one electrode. The surgical instrument further comprises a drive member, a motor assembly, and a control circuit. The control circuit is configured to cause the at least one electrode to deliver a therapeutic energy to the tissue in a first phase of a surgical treatment, cause the motor assembly to move the drive member to deploy staples into the tissue in a second phase of the surgical treatment, monitor a first tissue property in the first phase, and switch from the first phase to the second phase if at least one of two conditions is met, set a parameter of the second phase based on at least one measurement of the tissue property determined in the first phase, and monitor a second tissue property, in the second phase.
