    摘要： An endoscopic bipolar forceps includes a housing and a shaft affixed to the housing. The shaft includes a longitudinal axis defined therethrough and a pair of jaw members attached to a distal end thereof. The forceps also includes a drive assembly for moving one of the jaw members relative to the other jaw member from a first position wherein the movable jaw members are disposed in spaced relation relative to each other to a second position wherein the jaw members are closer one another for manipulating tissue. A movable handle is included which is rotatable about a pivot to force a drive flange of the movable handle into mechanical cooperation with the drive assembly to move the jaw members from the open and closed positions. The pivot is located a fixed distance from the longitudinal axis and the drive flange is located generally along the longitudinal axis. The forceps is connected to a source of electrosurgical energy connected to each jaw member such that the jaw members are capable of conducting bipolar energy through tissue held therebetween to effect a tissue seal.

    摘要： An endoscopic bipolar forceps includes a housing and a shaft, the shaft having an end effector assembly at its distal end. The end effector assembly includes two jaw members for grasping tissue therebetween. The jaw members are adapted to connect to an electrosurgical energy source which enable them to conduct energy through the tissue to create a tissue seal. A drive assembly is disposed within the housing which moves the jaw members. A switch is disposed within the housing which activates the electrosurgical energy. A knife assembly is included which is advanceable to cut tissue held between the jaw members. A movable handle is connected to the housing. Continual actuation of the movable handle engages the drive assembly to move the jaw members, engages the switch to activate the electrosurgical energy source to seal the tissue, and advances the knife assembly the cut the tissue disposed between the jaw members.

    摘要： An endoscopic bipolar forceps includes an elongated shaft having opposing jaw members at a distal end thereof. The jaw members are movable relative to one another from a first position wherein the jaw members are disposed in spaced relation relative to one another to a second position wherein the jaw members cooperate to grasp tissue therebetween. The forceps also includes a source of electrical energy connected to each jaw member such that the jaw members are capable of conducting energy through tissue held therebetween to effect a seal. A generally tube-like cutter is included which is slidably engaged about the elongated shaft and which is selectively movable about the elongated shaft to engage and cut tissue on at least one side of the jaw members while the tissue is engaged between jaw members.
