Abstract
A surgical stapling instrument includes an end effector that has a first jaw; a second jaw movable relative to the first jaw between an open configuration and a closed configuration to grasp tissue between the first jaw and the second jaw; an anvil; and a staple cartridge with staples deployable into the tissue and deformable by the anvil. The surgical stapling instrument further includes a control circuit configured to: determine tissue impedances at predetermined zones; detect an irregularity in tissue distribution within the end effector based on the tissue impedances; and adjust a closure parameter of the end effector in accordance with the irregularity.
