Abstract: A surgical instrument includes an end effector assembly and a switch assembly. The end effector assembly includes a monopolar assembly and a bipolar assembly. The switch assembly includes first and second bipolar inputs, first and second bipolar outputs, a monopolar input, and a monopolar output. The switch assembly is transitionable between a first condition, wherein the first and second bipolar inputs are coupled to the first and second bipolar outputs, respectively, for supplying energy to the bipolar assembly, and a second condition, wherein the monopolar input and the monopolar output are coupled to one another for supplying energy to the monopolar assembly.

Abstract: A surgical instrument includes an end effector and a housing mechanically coupled to the end effector. The end effector includes a first actuating device configured to perform a first surgical procedure and a second actuating device integrally associated with the first actuating device and configured to perform a second surgical procedure, the second surgical procedure being independently operable and different than the first surgical procedure. An outer portion of the first actuating device and an outer portion of the second actuating device form a portion of an outer housing of the end effector. The housing includes a first actuator, mechanically coupled to the first actuating device and configured to impart movement to the first actuating device and a second actuator, mechanically coupled to the second actuating device and configured to impart movement to the second actuating device.

Abstract: An endoscopic forceps is provided and includes a housing having a shaft. An end effector assembly operatively connects to a distal end of the shaft and has a pair of first and second jaw members. One of the first and second jaw members is movable relative to the other jaw member from an open position, to a clamping position. One of the first and second jaw members includes one or more cam slots defined therein and configured to receive a cam member that upon movement thereof rotates the movable jaw member from the open position to the clamping position. A resilient member is operably coupled to the jaw member that includes the one or more cam slots. The resilient member is configured to provide a camming force to the cam slot and to bias the first and second jaw members in the clamping position.

Abstract: An electrosurgical forceps includes a handle having a shaft extending therefrom defining a longitudinal axis. The handle is selectively movable to translate movement of the shaft along the longitudinal axis to actuate a pair of laterally spaced first and second jaw members pivotably connected to a distal end of the shaft. The first and second jaw members are moveable from an open position, wherein the first and second jaw members are in spaced relation relative to a stationary jaw member, to a closed position wherein the first and second jaw members cooperate with the stationary jaw member to grasp tissue therebetween. Each of the jaw members is adapted to connect to an electrosurgical energy source to conduct energy through tissue grasped therebetween to effect a tissue seal.
