Abstract
An auxiliary tubing probe for converting a monopolar electrosurgery probe having a main electrode at one end, into a bipolar eletrosurgery probe. The auxiliary probe has an inner electrically insulated tube in which the monopolar eletrosurgery probe is slidably inserted. An electric conductor extends externally over and along the inner insulated tube. An auxiliary electrode connected to the electric conductor projects forward away from the inner tube, in such a manner as to be adjacent to the main electrode when the monopolar electrosurgery probe has been inserted in the auxiliary probe. An outer electric insulator covers the electric conductor from the first extremity to the second extremity. The insertion of the auxiliary probe over the monopolar electrosurgery probe, and electricity going through the auxiliary electrosurgery probe and monopolar electrosurgery probe, allows conversion of the monopolar electrosurgery probe into a bipolar electrosurgery probe.

They comprise an electrical conducting cannula having one extremity connected to a power source and a second extremity ended by an emitting electrode.
Because of their single polarity, a grounding element is required under or near the patient. Since the 25 grounding element and the emitting electrode are separated by parts of the patient's body, the electric current emitted by the emitting electrode traverses those body parts .
The electric current sometimes causes damages to 3 o these body parts, damages that could be avoided by having a nearer grounding element.

DE6CRIPTION ~F ~o~REFFoo~n ~ . )r.Tr.~
RefeL~ring to Figure 1, there is shown an auxiliary tubing probe l according to the invention, for converting a monopolar eleL LLO~UL~Ly probe 3 shown in dotted lines into a bipolar ele-;LLU~UL~Ly probe 5.
The monopolar eleuLLu ,uLy~ry probe 3 preferably con6ists of a laparoscopic electrode or an electric conducting cannula. The monopolar ele-:L~u~,u~y~:Ly probe 3 has a main electrode 7 at one end having the shape of a hockey stick, and is electrically connected to a power source 9. The monopolar ele~:LLv~.uL~y probe 3 also has a 3topping flange 11, for stopping its insertion in the auxiliary probe 1. That stopping f lange 11 is star-shaped as shown on Figure 6.
The auxiliary tubing probe 1 comprises an inner electrically insulated tube 13 in whiah the monopolar ele~:LL o .uLyery probe 3 is slidably inserted. The inner electrically insulated tube 13 has a first and a second opposite ends 15 and 17. The insulated tube 13 preferably consists of polycarbonate. It may also consist of any material acting as an electric insulator.
As shown on Figure 2, at least one electric conductor 19 extends externally over and along the inner insulated tube 13 . This electric conductor 19 has a first extremity 21 and a second extremity 2 3 .
The auxiliary tubing probe 1 also comprises an auxiliary electrode 25 projecting forward from the first end 15 of the inner tube 13. The auxiliary electrode 25 preferably has the shape of a J-hook, but may also have the shape of a needle, a hockey stick, a L-hook or a spatula, as is known in this art.
The ~ ry electrode 25 is connected to the f irst extremity 21 of the at least one electric conductor 35 19. When the monopolar ele~LLu,,uLy~ry probe 3 has been ~ .
in3erted in the auxiliary probe 1, the auxiliary electrode 25 is adjacent to the main electrode 7 of the monopolar ele~ lV~ULgery probe 3.
The auxiliary tubing probe 1 further comprises an S outer electric insulator 27 covering the electrical conductor 19 from its first extremity 21 to its second extremity 23. The outer electric insulator 27 also covers the inner electrically insulated tube 13. The outer electric insulator 27 preferably consi6ts of polycarbonate.
It may also consist of any material which is biocompatible and may act as an electrical insulator.
The auxiliary probe 1 also has attachment mean3 for retaining the a~ 1 iAry probe 1 on the monopolar electlo~,uL~ry probe 3. The attachment means can be of any type but preferably comprises a pair of 0-rings 29 mounted in small grooves made in the inner auxiliary probe 1 near the second end 15 of the inner tube 13. The attachment mean6 may also consist in snug-fitting the ~ ry tubing probe 1 over the monopolar ele-;LLU:~ULy~Ly probe 3.
The auxiliary probe further comprises a disengaging flange 31 adjacent to the second end 17 of the inner tube 13, used to separate the auxiliary probe 1 from the monopolar ele.:LLv~uLyt!ry probe 3.
In a 6econd ~ L of the invention, shown on E'igure 4, the electrical conductor 19 is a metallic weaver 23 enveloping the inner insulated tube 13. The metallic weaver disposed in such a manner acts as a Faraday cage surrounding the monopolar ele.:LLu~uruery probe 3. Such a disposition improves the grounding effect of the auxiliary 3 0 tubing probe 1.
In a third c-mho~ t of the invention, shown on Figure 3, the at least one electrical conductor 19 is inserted in grooves 25 made in the inner electrically insulated tube 13.
In a fourth ~ t of the invention, shown on Figure 5, the outer electric insulator 27 and the inner electrically insulated tube 13 are combined in a single tube into which the at least one electric conductor 19 is inserted .
In use, a first connecting path may consist in connecting the monopolar electro,suL~eLy probe to the power source 9, and to use the auxiliary electrosurgery probe 1 as a floating ground. A second connecting path may be to connect the auxiliary ele~:Llo~uLy~:ry probe 1 to the power source 9 and to use the monopolar ele~:LLO~.UL~Ly probe as a floating ground. A third connecting path may consist in connecting the monopolar eleULL-~3UL~t:Ly probe 3 and the auxiliary eleuLl~,uL~ery probe 1 to the power source 9.
In operation, when the auxiliary tubing probe 1 is inserted over the monopolar eleULLO~UL-J~3ry probe 3 and when electricity circulates in the probes 1 and 3, the monopolar eleU~LUt~ULy~Ly probe 3 is converted into a bipolar eleuLLo.,uL Jery probe 5 .
The auxiliary tubing probe easily and temporarily transforms a monopolar electrosurgery probe in a bipolar electrosurgery probe which is electrically safe for both the patient and the surgeon.
Although the present invention has been explained hereinabove by way of preferred ~ r~ ts thereof, it should be pointed out that any modifications to these preferred ~-'i Ls, within the scope of the appended claims are not deemed to change or alter the nature and scope of the present invention.

said monopolar electrosurgery probe is a laparoscopic monopolar electrode;
said auxiliary electrode has the shape of a J-hook and said main electrode has the shape of a hockey stick;
said inner insulated tube and said outer electrical insulator are made of polycarbonate; and said monopolar electrosurgery probe has a stopping flange star-shaped.
15. The combination according to claim 14 further comprising:
a pair of O-rings mounted in small grooves made in an inner portion of said auxiliary probe near the second end of the inner tube; and a disengaging flange connected adjacent to the second end of said inner tube for use to separate said auxiliary probe from said monopolar electrosurgery probe.
a pair of O-rings mounted in small grooves made in an inner portion of said auxiliary probe near the second end of the inner tube; and a disengaging flange connected adjacent to the second end of said inner tube for use to separate said auxiliary probe from said monopolar electrosurgery probe.
16. An auxiliary probe according to claim 5 further comprising attachment means for retaining said auxiliary probe on said monopolar electrosurgery probe.
17. An auxiliary probe according to claim 16 further comprising a disengaging flange connected adjacent to the second end of the inner tube for use to separate said auxiliary probe from said monopolar electrosurgery probe.
18. An auxiliary probe according to claim 16 wherein said attachment means are a pair of O-rings mounted in small grooves made in an inner portion of said auxiliary probe near the second end of said inner tube.
