ABSTRACT:
A bipolar electrosurgical instrument is provided having a handle assembly, an elongated body portion, and a tool mechanism. The body portion comprises an outer tubular member and an inner rod member coaxially slidable within the outer tubular member. Attached to a distal end of the body portion is a tool mechanism. The tool mechanism includes pivotally connected jaw members operatively connected to the inner rod member for movement by the handle assembly between open and closed positions. Each jaw member is fabricated from insulating material and is provided with a conductive pathway. The conductive pathways are positioned to permit sparking between the pathways when the jaw members are open. As the jaw members are approximated, the insulating jaw member material blocks the electrical path between the conductive pathways to terminate electrical treatment of tissue positioned between the jaw members.
