1. A surgical instrument, comprising:
an end effector, comprising:
a first jaw;
a second jaw movable relative to the first jaw between an open configuration and a closed configuration to grasp tissue;
a staple cartridge; and
at least one electrode;
a drive member;
a motor assembly configured to generate drive motions to move the drive member; and
a control circuit 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 from the staple cartridge into the tissue in a second phase of the surgical treatment;
monitor a first tissue property in the first phase of the surgical treatment;
monitor an energy delivery time during which the at least one electrode delivers the therapeutic energy to the tissue in the first phase of the surgical treatment;
switch from the first phase of the surgical treatment to the second phase of the surgical treatment based on the first tissue property reaching or exceeding a predetermined threshold of the first tissue property prior to the energy delivery time reaching or exceeding a predetermined threshold time;
switch from the first phase of the surgical treatment to the second phase of the surgical treatment based on the energy delivery time reaching or exceeding the predetermined threshold time of the first phase prior to the first tissue property reaching or exceeding the predetermined threshold of the first tissue property;
set a parameter of the second phase of the surgical treatment based on at least one measurement of the first tissue property determined in the first phase of the surgical treatment; and
monitor a second tissue property, different from the first tissue property, in the second phase of the surgical treatment.
