1. An electrosurgical instrument for treating tissue, comprising:

  • a housing having a shaft extending therefrom having an axis A-A defined therethrough, the shaft being at least partially flexible and including first and second jaw members attached at a distal end thereof, each jaw member including an electrically conductive tissue contacting surface adapted to connect to a source of electrosurgical energy such that the electrically conductive tissue contacting surfaces are capable of conducting electrosurgical energy through tissue held therebetween;

    a drive assembly disposed in the housing including a first actuator operably coupled to a drive rod for reciprocation thereof wherein actuation of the first actuator reciprocates the drive rod which, in turn, moves the jaw members from a first position in spaced relation to one another to a second position closer to one another for engaging tissue; and

    a second actuator disposed on the housing being actuatable to articulate the shaft.
