摘要:
A surgical instrument can comprise a handle, a first conductor, a second conductor, and an end effector. The end effector can comprise a first jaw, a second jaw, wherein the first jaw is movable relative to the second jaw in order to capture tissue intermediate the first jaw and the second jaw, a first electrode electrically coupled with the first conductor, and a second electrode electrically coupled with the second conductor, wherein the second electrode is comprised of a material configured to have a first electrical resistance when a first pressure is applied to the material, and wherein the material is configured to have a second electrical resistance when a second pressure is applied to the material. In various circumstances, the material can be configured such that, once the applied pressure has exceeded a switching pressure, the resistance of the material can switch from the first resistance to the second resistance.
