    摘要： A surgical instrument can comprise an end effector including a plurality of jaws which can be configured to compress tissue therebetween. The end effector can further comprise one or more electrodes which can be configured to direct a flow of electrical current through the tissue in order to heat the tissue and denature collagen and/or other proteins within the tissue. As the tissue cools, the collagen and/or other proteins can renature and thereby seal the tissue. In certain embodiments, the end effector of the surgical instrument can further comprise movable portions which can apply a tension force to the tissue surrounding the tissue being sealed. In various circumstances, the tension force can reduce the over-denaturation, shrinkage, and/or other damage to the surrounding tissue caused by heat flowing from the end effector during the sealing process.

    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.

    摘要： A nested trigger assembly for a surgical instrument may generally comprise a first trigger and a second trigger, wherein the first trigger and the second trigger are movable together on a first stroke of the nested trigger assembly, wherein the second trigger is configured to be biased away from the first trigger after the first stroke and before a second stroke, and wherein the second trigger is configured to be moved toward to the first trigger during the second stroke. A surgical instrument may generally comprise a shaft comprising a proximal end and a distal end, a handle extending from the proximal end, wherein the handle comprises a gripping portion, and a nested trigger assembly extending from the handle. The nested trigger assemble may comprise one of a separable trigger assembly and a divisible trigger assembly.
