Abstract
An electrosurgical electrode shroud including a hollow substantially cylindrical member having a first end portion and a second end portion; the first end portion defining an opening which is configured and dimensioned to receive an electrosurgical electrode assembly therein; the second end portio n defining an opening which is configured and dimensioned to receive an electrode mounting portion of an electrosurgical instrument, wherein at leas t the second end portion is formed of a substantially translucent material. Th e electrosurgical electrode shroud may further include visual or tactile indicator on the second end portion for indicating a depth of penetration of the electrosurgical instrument within the second end portion when viewed by the surgeon through the translucent material.
Claims (16)
1. An electrosurgical electrode shroud comprising:
a hollow substantially cylindrical 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.
a hollow substantially cylindrical 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.
2. The electrosurgical electrode shroud as recited in claim 1 wherein an inside diameter of the opening defined by the first end portion is configured to fit an outside diameter of the electrosurgical electrode assembly received therein.
3. The electrosurgical electrode shroud as recited in claim 1 further comprising a transition portion between said first end portion and said second end portion.
4. The electrosurgical electrode shroud as recited in claim 3 wherein said transition portion is frustoconical in shape.
5. The electrosurgical electrode shroud as recited in claim 1 further comprising a visual indicator on said second end portion for indicating a depth of penetration of the electrosurgical instrument within said second end portion.
6. The efectrosurgical electrode shroud as recited in claim 1 further comprising a tactile indicator on said second end portion for indicating a depth of penetration of the electrosurgical instrument within said second end portion.
7. The electrosurgical electrode shroud as recited in claim 1 wherein an inside diameter of the opening defined by the second end portion is substantially equal to an outside diameter of the electrosurgical instrument received therein.
8. The electrosurgical electrode shroud as recited in claim 1 wherein the shroud is formed of an elastomeric material.
9. The electrosurgical electrode shroud as recited in claim 1 wherein the translucent material is substantially clear.
10. The electrosurgical electrode shroud as recited in claim 1 wherein the translucent material is tinted.
11. In an electrosurgical electrode assembly having an elongate electrically-conductive shaft member with a proximal end for receiving electrosurgical currents from an electrosurgical instrument and a distal end, wherein the improvement comprises:
an electrosurgical electrode shroud comprising a hollow substantially cylindrical 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 the electrosurgical electrode assembly therein; said second end portion defining an opening which is configured and dimensioned to receive an electrode mounting portion of the electrosurgical instrument, wherein said second end portion is formed of a substantially translucent material.
an electrosurgical electrode shroud comprising a hollow substantially cylindrical 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 the electrosurgical electrode assembly therein; said second end portion defining an opening which is configured and dimensioned to receive an electrode mounting portion of the electrosurgical instrument, wherein said second end portion is formed of a substantially translucent material.
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.
