    摘要： An endoscopic forceps includes a housing having a shaft attached thereto, the shaft including a pair of jaw members disposed at a distal end thereof. The forceps also includes a drive assembly disposed in the housing which moves the jaw members 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 are closer to one another for manipulating tissue. A pair of handles is operatively connected to the drive assembly and the handles are movable relative to the housing to actuate the drive assembly to move the jaw members. Each of the jaw members is adapted to connect to a source of electrical energy such that the jaw members are capable of conducting energy for treating tissue. The forceps also includes a first switch disposed on the housing which is activatable to selectively deliver energy of a first electrical potential to at least one jaw member for treating tissue in a monopolar fashion. A second switch is disposed on the housing and is activatable to selectively deliver energy of a first electrical potential to one jaw member and selectively deliver energy of a second electrical potential to the other jaw member for treating tissue in a bipolar fashion.

    摘要： A cable cooling apparatus, for dissipating heat generated by a cable, includes a housing disposed on a portion of a cable and defining a fluid-tight cavity therewithin. The housing is configured to cool at least a portion of the cable. The housing also includes one or more inlets, configured to receive fluid in the housing, and one or more outlets in fluid communication with an inlet for discharging the fluid from the housing. The fluid enters the housing through an inlet, circulates through a portion of the housing and absorbs thermal energy from a portion of the cable.

    摘要： An endoscopic forceps for treating tissue includes a housing having a shaft affixed thereto which has first and second jaw members attached to a distal end thereof. The forceps also includes an actuator for moving jaw members 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. Each of the jaw members is adapted to connect to a source of electrosurgical energy such that the jaw members are selectively capable of operating in a bipolar mode which enables the jaw members to conduct bipolar energy through tissue held therebetween to treat tissue. The forceps also includes a monopolar element housed within the first jaw member and integrally associated with the knife. The monopolar element is selectively movable from a first position within the first jaw member to a second position distal to the first jaw member. The monopolar element is adapted to connect to the source of electrosurgical energy such that the monopolar element is selectively activateable independent of the bipolar mode.

    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.
