An ultrasonic surgical instrument is described for use in medical procedures to, for example, dissect or cut living organic tissue. The ultrasonic surgical instrument includes an outer sheath, a waveguide, and an improved acoustic isolation element. The acoustic isolation element is bonded to both the ultrasonic waveguide and the interior surface of the outer sheath, creating an acoustic isolation seal. The improved acoustic isolation element seals the distal end of the ultrasonic instrument, substantially improving its ability to reduce or eliminate penetration by liquids or other contaminants during, for example, soaking or steam autoclave sterilization. |
