Abstract
Open electrosurgical forceps for sealing tissue are provided which include first and second shaft portions pivotably associated with one another. Each shaft portion has a jaw member disposed at a distal end thereof. Each of the jaw members includes an electrically conductive sealing surface adapted to communicate electrosurgical energy through tissue held therebetween and a slot formed through the sealing surface thereof. The forceps includes a cutting mechanism operatively associated with the first and second jaw members. The cutting mechanism includes a cutting element disposed within the slot of the at least one jaw member, the cutting element being movable from a first position wherein the cutting element is retracted within the at least one jaw member and a second position in which the cutting element at least partially projects from a sealing surface of the at least one jaw member.
