Abstract
A decoupling sleeve for inclusion in a fluid conduit of an ultrasonically-operated instrument, such as a surgical instrument, which is irrigated by irrigating fluid at the operative site. The decoupling sleeve includes a tubular thin-walled body portion defining spaced openings, and a collar member for retaining the decoupling sleeve in a tip cap sleeve member for the instrument. The inclusion of the decoupling sleeve in the irrigating fluid conduit intermediate a portion of an ultrasonically-operated tool and the interior of the tip cap sleeve member defining the fluid conduit impedes the transmission of ultrasonic energy through the fluid medium in the conduit, thus reducing objectionable cavitation and bubble formation at the operative site.
