12. The electrosurgical electrode assembly as recited in claim 11 further comprising at least one layer of insulating material formed on said electrically-conductive shaft.

13. The electrosurgical electrode assembly as recited in claim 12 further comprising a second layer of insulating material formed on said electrically-conductive shaft and at least partially covering said at least one layer of insulating material, wherein said second layer of insulating material includes a substantially conical shaped portion to prevent over insertion of the shaft member into a source of electrosurgical currents.

14. The electrosurgical electrode assembly as recited in claim 11 wherein said distal end includes a needle-shaped tip portion capable of penetrating the skin of a patient and exposed electrically for applying electrosurgical currents when said shaft member is connected to a source of electrosurgical currents.

15. The electrosurgical electrode as recited in claim 11 wherein the electrode shroud is co-axial with a longitudinal axis of said shaft member.

16. The electrosurgical electrode as recited in claim 11 wherein said distal end is spade-shaped.

17. An electrosurgical electrode shroud comprising:

a hollow member having a first end portion and a second end portion, said first end portion defining an opening which is configured and dimensioned to receive an electrosurgical electrode assembly therein, said second end portion defining an opening which is configured and dimensioned to receive an electrode mounting portion of an electrosurgical instrument, wherein at least said second end portion is formed of a substantially translucent material; and

wherein said second end portion further includes an indicator for indicating a depth of penetration of the electrosurgical instrument within said second end portion.

18. The electrosurgical electrode shroud as recited in claim 17 wherein at least a portion of the hollow member has a shape which is at least one of cylindrical and frusto-conical.

19. The electrosurgical electrode shroud as recited in claim 18 comprising a transition portion between said first end portion and said second end portion.
