Claim 13:
14. A tool assembly for use with an electrosurgical device, the tool assembly comprising:
an electrical insulator defining a longitudinal axis;
an active lead fixed to a distal edge of the electrical insulator;
a camming pin received through a slot defined by the electrical insulator, the camming pin configured for axial movement within the slot along the longitudinal axis;
a return lead coupled to the camming pin such that the return lead is configured to:
move axially along the longitudinal axis and relative to the electrical insulator in response to corresponding axial movement of the camming pin along the longitudinal axis; and
rotate about the camming pin relative to the electrical insulator; and

a spring configured to bias the camming pin distally along the longitudinal axis such that proximal axial movement of the return lead is against the bias of the spring.
