ABSTRACT:
A disposable open electrosurgical forceps for sealing tissue is disclosed in the present disclosure. The disposable open electrosurgical forceps comprise a pair of first and second shaft members containing a fiber reinforced thermoplastic blend material having fiber strands of at least 2 millimeters in length. Each shaft member includes a jaw member disposed at a distal end thereof which 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 also 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 mechanism therealong. An actuator is included for selectively advancing the cutting mechanism from a first position wherein the cutting mechanism is disposed proximal to tissue held between the jaw members to at least one subsequent position wherein the cutting mechanism is disposed distal to tissue held between the jaw members. The actuator includes a trigger which cooperates with a rack and pinion system to advance the cutting mechanism from the first to second positions through tissue held therebetween.
