Claim 0:
1. A tool assembly for use with an electrosurgical device, the tool assembly comprising:
a base portion;
an electrical insulator extending distally from the base portion and defining a slot configured to receive a camming pin, the camming pin configured for movement within the slot;
a return lead adapted to be electrically coupled to a return terminal, the return lead movably supported on the electrical insulator;
an active lead adapted to be electrically coupled to an active terminal, the active lead fixed to the electrical insulator, wherein the return lead is rotatable about a pivot and translatable along a longitudinal axis relative to the electrical insulator and the active lead, wherein, upon activation, electrosurgical energy is transmitted from the active lead through tissue to the return lead to cut tissue in contact with the active lead; and
a spring coupled to the camming pin and configured to bias the return lead to a first rotational position, wherein the return lead is configured to rotate to a second rotational position against the bias of the spring.
