Abstract

An electrosurgical instrument connectivity system providing monopolar and bipolar plugs each having a plurality of conductors which allow for use of combination monopolar/bipolar electrosurgical devices with industry standard electrosurgical generator outlets.

Claims

1. An electrical cable comprising:

a first plug, including a first, second and third conductor extending therefrom, wherein the first and second conductors are first and second electrosurgical leads and the third conductor is a first electrosurgical activation switch return lead;

a first electrosurgical activation switch connected between one of the electrosurgical leads and the first electrosurgical activation switch return lead;

a second plug adapted to plug including a fourth, fifth and optionally a sixth conductor extending therefrom, wherein the fourth conductor is a third electrosurgical lead and the fifth and sixth conductors are second and third electrosurgical activation switch return leads;

a second electrosurgical activation switch connected between the fourth conductor and the fifth conductor;

a third electrosurgical activation switch connected between the fourth conductor and the sixth conductor;

wherein the third conductor is common with one of the fifth or sixth conductors.

6. The cable of claim 1, wherein the cable includes exactly five conductors.

7. The cable of claim 1, wherein the fourth conductor is common with either the first or second conductor.

8. The cable of claim 1 wherein:

(i) the first plug engages a bipolar outlet;

(ii) the second plug engages a monopolar outlet;

(iii) the first electrosurgical activation switch is a bipolar activation switch; and

(iv) the second and third electrosurgical activation switches are monopolar activation switches.

9. The cable of claim 8, wherein the fifth conductor is a monopolar cut switch return lead.

10. The cable of claim 8, wherein sixth conductor is a monopolar coag switch return lead.

11. The cable of claim 8, wherein the third conductor is common with the fifth conductor.

12. The cable of claim 8, wherein the third conductor is common with the sixth conductor.

2. An electrical cable for a monopolar/bipolar device comprising:

a first plug configured to plug into a bipolar outlet and including three conductors extending therefrom wherein a first and second conductor are bipolar HF leads, and a third conductor is a bipolar switch return lead;

a bipolar activation switch connecting one of the bipolar HF leads and the bipolar switch return lead;

a second plug configured to plug into a monopolar outlet and including two conductors extending therefrom wherein a fourth conductor is a monopolar HF lead and a fifth conductor is a monopolar switch return lead;

a monopolar activation switch connecting the monopolar HF lead and the monopolar switch return lead;

wherein the bipolar switch return lead is common with the monopolar switch return leads, so that four or less conductors are used.

3. The cable of claim 2, wherein the monopolar switch lead is a monopolar cut switch return lead or a monopolar coag return lead.

4. The cable of claim 3, wherein the bipolar switch return lead is common with the monopolar cut switch return lead.

5. The cable of claim 3, wherein the bipolar witch return lead is common with the monopolar coag switch return lead.

14. The cable of claim 2, wherein the monopolar HF lead is common with one of the bipolar HF leads so that only three conductors are used.

13. An electrical cable comprising:

a first plug configured to plug into a bipolar outlet, the first plug including a first, second and third bipolar conductor extending therefrom, wherein the first and second bipolar conductors are bipolar HF leads and the third bipolar conductor is a bipolar switch return lead,

a bipolar activation switch connected between one of the bipolar HF leads and the bipolar switch return lead

a second plug adapted to plug into a monopolar outlet, the second plug including a first, second and third monopolar conductor extending therefrom, wherein the first monopolar conductor is a monopolar HF lead and the second and third monopolar conductors are monopolar switch return leads;

a monopolar cut activation switch connected between the monopolar HF lead and the second monopolar switch return lead;

a monopolar coag activation switch connected between the monopolar HF lead and the third monopolar switch return lead;

wherein the bipolar switch return lead also operates as one of the second or third monopolar switch return leads.
