ABSTRACT:
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.
