ABSTRACT:
An open electrosurgical forceps for sealing tissue includes a pair of first and second shaft members each having a jaw member disposed at a distal end thereof. The jaw members are movable from a first position in spaced relation relative to one another to at least one subsequent position wherein the jaw members cooperate to grasp tissue therebetween. Each of the jaw members includes an electrically conductive sealing plate for communicating electrosurgical energy through tissue held therebetween. At least one of the jaw members includes a knife channel defined along a length thereof which is dimensioned to reciprocate a cutting blade therealong. An actuator is included which is operatively connected to one of the shaft members and selectively advances the cutting mechanism from a first position wherein the cutting blade is disposed proximal to tissue held between the jaw members to at least one subsequent position wherein the cutting blade is disposed distal to tissue held between the jaw members. The cutting blade is a generally hourglass-shaped flexible cutting blade having a notch disposed generally midway therealong which facilitates distal translation of the knife within the knife channel.
