Claim:
A disposable attachment for converting a mechanical surgical instrument having first and second members coupled at a pivot into an electro-surgical instrument, the attachment comprising: a first cover element; and a second cover element, each cover element including a non-conductive sheath defining a single pocket, wherein an outer surface of the sheath comprises a D-shaped cross-section having an arcuate section and a linear section, an electrically conductive element having a bottom surface directly attached to the linear section of the outer surface of the sheath, and a wire extending from the electrically conductive element, wherein no portion of the wire is within the sheath, a proximal end of the first cover element is slidable over a distal end of a first member by inserting the distal end of the first member into the pocket of the sheath of the first cover element, and a proximal end of the second cover element is slidable over a distal end of a second member by inserting the distal end of the second member into the pocket of the sheath of the second cover element, and each cover element is free of an open slot formed within the sheath.
