Surgical instruments can be set up on a Mayo surgical stand with a removable stainless steel tray. The Mayo stand comes in two styles: an easily maneuverable four-wheeled version and a two-wheeled version. The stand may be adjusted to the desired height. Trays should be kept neat and all instruments should be placed so that needle-stick injuries are minimized. Two trays can be prepared and sterilized for use: an excision tray and a repair tray.
The organization of the excision tray is important for safety and efficiency (Fig. 4.10). At the very least it should contain a scalpel handle, a ruler, a curette for debulking tumors, tissue scissors, forceps, and either a marking pen or a cup containing Gentian violet to delineate tumor margins for Mohs micrographic surgery or excision. The excision tray should also contain towel clamps for holding sterile drapes if the drapes are not self-adhering. Sterile gauze, scalpel blades, and Telfa (Tyco Healthcare Group LP, Mansfield, MA) pads to transport surgical specimens to the laboratory should be added when the tray is opened. Cotton-tipped applicators are also useful for hemostasis and the stick can be used for marking with Gentian violet.
The repair tray should contain roughly the same items as the excision tray, plus additional specific instruments (Fig. 4.11). The repair tray may also include a needle holder, undermining and suture-cutting scissors, a variety of forceps, skin hooks, and a cup with sterile saline for storing skin grafts. Sterile gauze, cotton-tipped applicators, scalpel blades, and suture should be added when the tray is opened.
