    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 in order to capture tissue therebetween. In various embodiments, the first and second jaws can comprise one or more electrodes configured to apply a voltage across the tissue, wherein at least one of the electrodes can comprise a conductive material positioned within a non-conductive, or high-resistance, material. In use, current flowing through the conductive material can heat the conductive material and cause it to evaporate and leave behind the non-conductive material. In such circumstances, the current flowing through the electrode may cease or may be substantially reduced.

    摘要： In various embodiments, a surgical instrument is provided that may comprise an end effector for performing a surgical procedure on tissue, for example. The end effector may comprise a pair of jaws, a closure beam, and a cutting member. The closure beam and the cutting member may be releasably coupled together by an interlocking member such that movement of the cutting member may cause the closure beam to also move relative to the jaws and cause the jaws to close and grip tissue, for example. The interlocking member may then unlock, allowing the cutting member to move through the gripped tissue and relative to the closure beam. Additionally, the cutting member and closure beam may be operated by a single trigger, which may be configured to provide haptic feedback to a user at various stages. Further, the jaws may be electrically energized to deliver energy and/or seal the gripped tissue.

    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 in order to capture tissue therebetween. In various embodiments, the first and second jaws can comprise one or more electrodes configured to apply a voltage across the tissue, wherein one or both of the first and second jaws can include a plurality of electrodes each comprised of a positive temperature coefficient material having a different switching temperature. The electrical resistances of the electrodes can increase significantly once the temperature of the electrodes exceed their switching temperatures and, owing to the increased electrical resistance, the flow of current through the electrodes can be reduced and/or prevented. In various circumstances, the different switching temperatures of the electrodes can allow some of the electrodes to switch off before the other electrodes.
