ABSTRACT:
Several embodiments of an electrocautery probe with a variable morphology electrode are disclosed. In one embodiment, the probe has two arms and the electrode is attached to distal ends of the arms. Movement of the distal ends of the arms relative to each other changes the morphology of the electrode. Several electrode embodiments and several ways of moving the distal ends are also disclosed. In another embodiment the electrocautery probe with a variable morphology electrode includes a hollow probe arm within which the electrode is mounted for movement relative to the hollow probe arm. Movement of the electrode relative to the hollow probe arm changes the morphology of the electrode. Several electrode embodiments for use with the hollow probe arm are disclosed.
