An energizable surgical attachment is configured for positioning about a shaft of a surgical instrument. The energizable surgical attachment includes an outer sheath defining a lumen extending longitudinally through the outer sheath, an energizable rod member coupled to the outer sheath, a connector attachment electrically coupled to the energizable rod member, and at least one o-ring disposed within the lumen of the outer sheath. At least a portion of the energizable rod member extends distally from the distal end of the outer sheath. The o-ring(s) are configured to establish a fluid-tight seal between the outer sheath and the shaft of the surgical instrument and to bias the outer sheath towards a stationary position relative to the shaft of the surgical instrument.
