摘要:
An end effector assembly for use with a bipolar forceps includes a pair of opposing first and second jaw members at least one of which being movable relative to the other to grasp tissue therebetween. Each jaw member includes a pair of spaced apart, electrically conductive tissue sealing surfaces. Each tissue sealing surface is adapted to connect to a source of electrosurgical energy to conduct electrosurgical energy through tissue held therebetween to effect a tissue seal. The forceps also includes an insulator disposed between each pair of electrically conductive sealing surfaces and an electrically conductive cutting element disposed within each insulator and defining a geometrical configuration including a plurality of peaks having a period that is a multiple of an operating frequency of the electrosurgical energy. The cutting elements are adapted to connect to the source of electrosurgical energy to conduct electrosurgical energy through tissue held therebetween to effect a tissue cut.
