  • Patent number: 9168088
    Abstract: An end effector of a forceps includes first and second jaw members movable between spaced-apart and approximated positions for grasping tissue. Each jaw member includes a tissue sealing plate that is selectively energizable. The tissue sealing plates are configured to conduct energy therebetween and though tissue to seal tissue. A knife includes a distal surface and an upper surface. The knife is selectively translatable between a retracted position and an extended position wherein the knife extends between the jaw members. The distal surface is configured for dynamic tissue cutting upon translation of the knife from the retracted to the extended position. The upper surface is configured for static tissue cutting with the knife in the extended position. The knife is selectively energizable and is configured to conduct energy between the knife and one or both of the tissue sealing plates and through tissue to electrically cut tissue.

  • Publication number: 20150257818
    Abstract: A forceps includes an end effector assembly having a stop and a plurality of overmold teeth within at least one jaw member. One (or both) of the jaw members is moveable relative to the other between a spaced-apart position and an approximated position for grasping tissue therebetween. One (or both) of the jaw members includes a stop molded within an insulative housing, and an insulator plate with the overmold teeth formed from plastic. The overmold teeth extend through openings within a sealing plate and protrude past the tissue sealing surface of the sealing plate. The stop primarily controls the gap distance between opposing jaw members by bearing most of an applied load and the overmold teeth assist in controlling the gap distance by bearing the remaining applied load.

  • Patent number: 8469992
    Abstract: An endoscopic forceps is provided. The endoscopic forceps includes a housing having a shaft that extends therefrom and defines a longitudinal axis therethrough. An end effector assembly operatively connects to a distal end of the shaft and has a movable jaw member and a non-movable jaw member. The movable jaw member has a substantially flexible medial portion and is movable relative to the non-movable jaw member from an initial position for positioning tissue therebetween, to a subsequent or clamping position wherein the movable and non-movable jaw members cooperate to grasp tissue therebetween. A drive assembly is operably coupled to the housing and includes a drive wire that operably couples to the movable jaw member. Proximal movement of the drive rod causes the medial portion of the movable jaw member to flex inwardly along a substantial length thereof and toward the non-movable jaw member.
