    摘要: A surgical instrument (1000) includes an end effector assembly (200) including first and second grasping components (210, 220) each defining a tissue-contacting portion (214, 218, 224, 228). One or both of the first or second grasping components (210, 220 ) is movable relative to the other between an open position and a closed position. In the closed position, the first and second tissue-contacting portions (214, 218, 224, 228) cooperate to define a grasping area therebetween. One or both of the first or second grasping components (210, 220) is configured to apply energy from the tissue- contacting portion (214, 218, 224, 228) thereof to tissue disposed within the grasping area to treat tissue. The tissue-contacting portion (214, 224) of the first grasping component (210) defines a first opening (219) therethrough. The first opening (219) is disposed within the grasping area and in communication with a first lumen (118) defined at least partially through the first grasping component (210). The first lumen (118) is adapted to connect to a source of vacuum (300) to enable aspiration through the first opening (219).

    摘要: An end effector for an electrosurgical instrument is disclosed which includes a first jaw, a first energy delivery surface, a first distal end, and a first proximal end. A second jaw of the end effector includes a second energy delivery surface, a second distal end, and a second proximal end. The end effector also includes an electrically conductive gap setting member which defines a distal gap distance between the first and second energy delivery surfaces. At least one pivot is fixed to one of the jaws to set a proximal gap distance between the first and second energy delivery surfaces. A method for making an end effector and a method for assembling an end effector for an electrosurgical instrument are also disclosed.

    摘要: A device for treating a tissue includes a capsule extending longitudinally from a proximal end to a distal end and including a channel extending therethrough, the capsule releasably coupled to a proximal portion of the device and clip arms, proximal ends of which are slidably received within the channel of the capsule so that the clip arms are movable between an open configuration, and a closed configuration. A core member is coupled to the clip arms, the core member including a proximal portion and a distal portion releasably connected to one another so that, when the core member is subjected to a predetermined load, the proximal and distal portions are separated from one another. An electrically conductive control member is connected to the core member, a proximal end of the connected member connected to a power source for delivering an electrical current to the clip arms.

    摘要: An end effector assembly (100, 200) of an electrosurgical forceps (10, 10') includes first and second jaw members (110, 120, 210, 220). At least one of the jaw members (110, 120, 210, 220) is movable relative to the other between a spaced-apart position and an approximated position. At least one of the jaw members (110, 120, 210, 220) includes an electrically-conductive inner member (115, 125) defining an outer surface, a first electrically-insulative layer (116, 126) disposed on a portion of the outer surface of the electrically-conductive inner member (115, 125), a second electrically-insulative layer (117, 127) disposed on another portion of the outer surface of the electrically-conductive inner member (115, 125), and an electrode (118, 128) disposed on the second electrically-insulative layer (117, 127) and electrically coupled to the electrically-conductive inner member (115, 125). The electrode (118, 128) defines a tissue-treating surface of the corresponding jaw member (110, 120, 210, 220). The first electrically-insulative layer (116, 126) has a thermal conductivity greater than that of the second electrically-insulative layer (117, 127).
