OG exemplary drawing
 
1. A surgical system, comprising:
an end effector, comprising:
a clamp arm;
a tissue contacting surface, wherein the clamp arm is movable relative to the tissue contacting surface to capture tissue therebetween; and
a circuit defining a plurality of segmented sections within the end effector, wherein the plurality of segmented sections comprises a first segmented section comprising a first impedance sensor, configured to:
derive a parameter associated with tissue positioned in the first segmented section; and
deliver electrosurgical energy to the tissue positioned in the first segmented section;
a motor configured to move the clamp arm relative to the tissue contacting surface;
a current sensor configured to sense a current draw of the motor; and
a control system operably coupled to the circuit and the current sensor, wherein the control system is configured to:
interrogate the first impedance sensor to determine a value of the parameter associated with the tissue positioned in the first segmented section;
interrogate the current sensor to determine the current draw;
compare the value of the parameter associated with the tissue positioned in the first segmented section to a threshold value;
compare the current draw to a threshold current draw; and
deactivate the first segmented section based on the comparisons.
