    摘要: An electrosurgical surgical instrument can comprise a handle and an end effector, wherein the end effector can comprise first and second jaws which can be opened and closed to capture tissue therebetween. One or both of the first and second jaws can comprise a plurality of electrodes which can be sequentially activated. The electrodes can be activated in a pre-determined order in connection with a cutting member being advanced through the tissue. In various embodiments, the electrodes can be deactivated in a predetermined order. In certain embodiments, the electrodes can be comprised of a positive temperature coefficient material which can allow the electrodes to be sequentially deactivated.

    摘要: A surgical instrument can comprise a handle and an end effector, wherein the end effector can comprise first and second jaws which can be opened and closed in order to capture tissue therebetween. The surgical instrument can further comprise a shaft extending between the handle and the effector and means for articulating the end effector relative to the shaft. The articulating means can comprise a portion of the shaft which is rotatable about a first axis in order to articulate the end effector about a second axis. In at least one embodiment, the shaft can comprise a first portion including a cam and a second portion including a cam follower, wherein the rotation of the second portion and the interaction of the cam and cam follower can cause the second portion to pivot relative to the first portion.
