Abstract

An assembly and method for connecting between two electrical components, according to which an electrical current path is established between the two components, and an additional path is established for transmitting any electrical noise generated during operation of the components.

Claims

1. A method for connecting between an electrical surgical instrument (first component) to an electrical power supply (second component), the method comprising establishing an electrical current path between the instrument and the supply, and establishing an additional path for transmitting any electrical noise generated during the operation of the components.

5. The method of claim 17 wherein the second-mentioned step of establishing comprises extending an electrical conductive shield around at least a portion of the conductor, and electrically connecting one end of the shield to one of the components, wherein the other end of the shield is not connected to either component.

6. The method of claim 18 wherein the electrical noise is transmitted to the one component via the shield.

7. The method of claim 19 further comprising connecting the one end of the shield to ground at the one component to dissipate the electrical noise.

8. The method of claim 18 further comprising directing the electrical noise through the shield to a ground connection at the one component.

9. The method of claim 18 further comprising connecting a connector to the conductor, and engaging the connector with the one component to electrically connect the conductor to the one component so that the connector forms a portion of the electrical current path.

10. The method of claim 22 further comprising connecting the connecter to the shield for electrically connecting the shield to ground at the one component so that the shield forms a portion of the additional path.

11. The method of claim 22 wherein the connector is connected to one end of the conductor and further comprising connecting another connector to the other end of the conductor, and engaging the other connector with the other component to electrically connect the conductor to the other component so that the other connector forms a portion of the electrical current path.

12. The method of claim 17 further comprising connecting one connector to one end of the conductor, engaging the one connector with the one component to electrically connect the conductor to the one component, connecting another connector to the other end of the conductor, and engaging the other connector with the other component to electrically connect the conductor to the other component, wherein the connectors each form a portion of the electrical current path.

13. The method of claim 25 further comprising connecting one end of the shield to the one connector, and extending the other end of the shield proximately to the other connector without the shield being connected to the other connector.

14. The method of claim 26 further comprising establishing separate electrical conductive paths in the one connector for the current flowing through the conductor and for the electrical noise flowing through the shield so that the connector forms a portion of the electrical current path and a portion of the additional path.

2. The method of claim 14 wherein the additional path is electrically isolated from the electric current path.

3. The method of claim 14 wherein the additional path is connected to ground at the other component.

4. The method of claim 14 wherein the first-mentioned step of establishing comprises connecting at least one electrical conductor between the two components.
