Protection sleeve for reusable handheld instrument

A medical kit, comprising:

• a medical device comprising an electrically conductive wire;
• a handheld instrument comprising an electrical port having at least one electrical terminal;
• and
• a sterile adapter comprising a sterile sleeve sized to removably contain the handheld instrument, a hub assembly affixed to the sterile sleeve for receiving a proximal end of the electrically conductive wire of the medical device, and an electrically conductive shaft affixed to the hub assembly and contained within the sterile sleeve, the electrically conductive shaft having a distal end affixed to the hub assembly and a proximal end configured for being inserted into the electrical port of the handheld instrument, such that the at least one electrical terminal of the handheld instrument electrically contacts the electrically conductive shaft, the electrically conductive shaft having a lumen into which the proximal end of the electrically conductive wire of the medical device may be slidably disposed when received by the hub assembly, such that electrically conductive wire is electrically coupled to the at least one electrical terminal of the handheld instrument via the electrically conductive shaft of the sterile adapter.
