Claims13
A method of coating a slip ring for use with a surgical instrument, wherein the method comprises the steps of:
- providing a slip ring including a plurality of conductive elements;
- and
- depositing a compressible material onto the conductive elements of the slip ring, the compressible material comprising a first conductivity in an uncompressed configuration and a second conductivity in a compressed configuration;
- wherein the second conductivity is greater than the first conductivity and is less conductive than the conductive elements.
A method of preparing a slip ring for use with a surgical instrument, wherein the method comprises the steps of:
- providing a non-conductive base;
- fixing a plurality of concentric spaced electrical contacts on a first side of the non-conductive base;
- forming interconnecting electrical paths on a second side of the non-conductive base;
- and
- coating the electrical contacts with a compressible material comprising a first conductivity in an uncompressed configuration and a second conductivity in a compressed configuration;
- wherein the second conductivity is greater than the first conductivity and is less conductive than the electrical contacts.
A method of preparing a slip ring for use with a surgical instrument, wherein the method comprises the steps of:
- providing a base;
- providing a plurality of concentric conductors comprised of a carbon-filled polymer;
- fixing the plurality of concentric conductors on a side of the base;
- and
- depositing a compressible material on the concentric conductors, the compressible material comprising a first conductivity in an uncompressed configuration and a second conductivity in a compressed configuration;
- wherein the second conductivity is greater than the first conductivity and is less conductive than the concentric conductors.
