  • Patent number: 11826090
    Abstract: A bipolar forceps includes a mechanical forceps including first and second shafts each having a jaw member extending from a distal end thereof and a handle disposed at a proximal end thereof for effecting movement of the jaw members relative to one another about a pivot. A disposable housing is configured to releasably couple to at least one of the shafts and an electrode assembly is associated with the disposable housing. The electrode assembly includes electrodes releasably coupleable to the jaw members. At least one of the electrodes includes a knife channel configured to receive a knife blade therethrough to cut tissue grasped between the jaw members. A switch is configured to initiate delivery of electrosurgical energy from the source of electrosurgical energy to the electrodes. An actuation mechanism is configured to selectively advance the knife blade through the knife channel to cut tissue.

  • Patent number: 10959770
    Abstract: A method of assembling an electrosurgical instrument includes coupling first and second shafts to each other about a pivot. Each of the shafts has an interior side facing the other shaft and an exterior side opposite the interior side. The method also includes disposing a knife blade at least partially through a passageway defined through the pivot from the exterior side of the first shaft and coupling a knife actuation mechanism to the first shaft from the exterior side of the first shaft. The knife actuation mechanism is configured to move the knife blade through the passageway.

  • Patent number: 10245103
    Abstract: A jaw member includes an insulative member and a substrate. The substrate is formed as a single, integral component that has first and second side portions interconnected by a connector portion. The connector portion has first and second side portions that are interconnected by an arc-shaped portion. The connector portion is configured to be removed before use of the jaw member such that the first and second portions are electrically insulated from one another.

  • Patent number: 9370393
    Abstract: A forceps includes an end effector assembly including a pair of jaw members disposed in opposing relation relative to one another. At least one jaw member is moveable relative to the other between a spaced apart position, a first approximated position, and a second approximated position. The jaw members are configured to apply a pre-determined pressure to tissue disposed therebetween in each of the first and second approximated positions. A sealing pressure is applied to tissue disposed between the jaw members when the jaw members are in the first approximated position. A cutting pressure is applied to tissue disposed between the jaw members when the jaw members are in the second approximated position.
