Mayo stands are designed to hold instruments for use in procedures and surgery. They come is several different forms and materials. Most come with removable trays to make cleaning easy. All have a height adjustments but many have different control or locking mechanisms. Some are hand controlled such as knobs while others offer various foot controls.
There are different types and materials used each with a different purpose in mind. The two primary metals used are chrome plated metals, generally steel, and stainless steel.
Chrome plated materials can be chipped plus corrode making them unsuitable in high volume areas or where they may get bumped. Plating is always only as good as the shop that did the work. They are shiny when new and are ideal for an office with limited need. They cost less and generally would not be good for a heavy load of instruments. Many tables are load rated often in pounds.
Stainless steel is a metal ideal for many medical applications. It is durable and has no plating so there is no risk of chipping. It is naturally corrosion resistant and almost impossible to tarnish or scratch. This makes it safe for most disinfectants and general purpose cleaners so the clean look will persist over the years. However, they cost more and are often designed for heavier instrument loads.
Single pole Mayo stands are designed for light duty service and are often height adjustable with a hand locking knob located on the post.
Dual post Mayo stands offer more stability and in general can handle more weight.
Heavier duty Mayo stands are generally made with stainless steel often offer thumb or foot controls as an alternative to the hand knob to lock in the height.
Lift Assist and Ventric Mayo Tables are designed for large heavy instrument sets such as those needed for ortho. These tables crank up and down then you can store the crank on the main pole. Additionally they offer larger overall surface area.
