  • Patent number: 10130414
    Abstract: A sealing instrument (10) including two branches (15, 16) with sealing jaws (19, 20, 36, 37) acted on by a sealing voltage preferably between 80 and 120 volts. Tissue receptacles (53, 54) are separated from one another by a wall-like extension (24), which at its lower edge carries a cutting electrode (31), are defined between the branches (15, 16). A cutting voltage from 300 to 500 volts is applied between a branch (16) and the cutting electrode. When the branches are closed the grasped tissue is sealed simultaneously between the sealing jaws (19, 36 and 20, 37) and is severed by the cutting electrode (31). Even though the tissue is severed completely; for example after 0.3 to 0.5 seconds and the sealing requires more time, the rolls of tissue grasped in the tissue receptacles (53, 54) act as form-fitting protection of the vessel edges in the tool (12).

  • Patent number: 10117704
    Abstract: A surgical instrument includes a housing, energizable member, first activation switch, cable assembly, and second activation switch. The housing is operatively associated with the energizable member. The first activation switch is coupled to the energizable member and is selectively transitionable from an open condition to a closed condition. The cable assembly is coupled to the housing at a first end and includes a plug at a second, opposite end, the plug housing a second activation switch selectively transitionable from an open condition to a closed condition. The plug is adapted to connect to the source of electrosurgical energy, wherein transitioning of the first activation switch from the open condition to the closed condition transitions the second activation switch from the open condition to the closed condition such that the second activation switch communicates with the source of electrosurgical energy to initiate the supply of energy to the energizable member.

  • Patent number: 10045812
    Abstract: A method of surgery includes grasping tissue between tissue-treating plates of first and second jaw members by moving the first and second jaw members from a spaced-apart position to a first approximated position, energizing the tissue-treating plates to conduct energy through the grasped tissue to treat tissue, and separating grasped and treated tissue by moving the first and second jaw members from the first approximated position to a second approximated position. Moving the first and second jaw members from the first approximated position to the second approximated position laterally shifts the jaw members relative to one another from an aligned orientation, wherein the tissue-treating plates are aligned with one another, to an offset orientation, wherein the tissue-treating plates are offset relative to one another.

  • Patent number: 9993288
    Abstract: A forceps includes first and second shaft members, each having a jaw member disposed at a distal end thereof. The first and second shaft members are pivotably coupled to one another toward the distal ends thereof and are moveable relative to one another between an open position and a closed position for moving the jaw members between a spaced-apart position and an approximated position. A knife assembly including a handle and a knife extending from the handle is also provided. The knife assembly is selectively translatable between a retracted position and an extended position, wherein the knife extends between the jaw members. The handle is disposed between the first and second shaft members and is configured to block further closure of the first and second shaft members beyond the closed position, thereby defining a minimum gap distance between the jaw members.
