Here are some features and points about the Mayo trolley:

1. Design: It typically consists of a stainless steel tray on top of a mobile stand. The tray is detachable for cleaning and sterilization.
2. Adjustable Height: The height of the Mayo trolley can be adjusted to cater to the specific needs of the procedure and the comfort of the surgical team.
3. Wheels: The trolley has wheels or casters, making it easy to move around the operating room. These often come with locking mechanisms to ensure stability during surgery.
4. Single-Use Sterile Drapes: Before surgery, the Mayo tray is usually covered with a sterile drape to maintain a sterile field. This drape is typically discarded after the surgery.
5. Instrument Set-Up: Surgical instruments are organized on the Mayo trolley in the order they’ll be used, providing easy and efficient access for the surgeon. This setup is often done by a scrub nurse or surgical technologist.
6. Size: The trolley is usually compact, allowing it to fit comfortably in the operating room without obstructing movement.
7. Multiple Uses: While most commonly associated with surgery, Mayo trolleys can also be found in other medical settings, like dental offices or minor procedure rooms, where they serve similar purposes of holding instruments and supplies.
8. Maintenance: Given their crucial role in surgeries, Mayo trolleys must be meticulously cleaned, and the tray sterilized between procedures to prevent any risk of infection.
