Abstract:
An electrosurgical instrument (12, fig. 1) including an elongated shaft (22) and a non-conductive handle (20) is disclosed. The shaft defines a proximal section (40), a distal section (42), and an internal lumen (50) extending from the proximal section. The distal section forms an electrically conductive tip (44) and defines at least one passage (52) for distributing fluid. Further, the shaft is adapted to be transitionable from a straight state to a first bent state (fig. 5). The shaft is capable of independently maintaining the distinct shapes associated with the straight state and the first bent state. The handle is rigidly coupled to the proximal section of the shaft. With this in mind, an exterior surface of the shaft distal the handle and proximal the distal section is electrically nonconductive. In one preferred embodiment, the shaft is comprised of an elongated electrode body surrounded by an electrical insulator.
