Suppport pad coupling mechanism for surgical table extension unit and surgical table
A support pad coupling mechanism for a surgical table extension unit and a surgical table are disclosed. The surgical table extension unit includes an extension adapter and a support pad. A lower side of the support pad is provided with two coupling plates that are perpendicular to the support pad. Each coupling plate is provided with a hook portion and a first position-limiting post. The first position-limiting posts extend along a direction perpendicular to the coupling plates. The extension adapter is provided with two second position-limiting posts that cooperate with the hook portions and two position-limiting recessed portions that cooperate with the first position-limiting posts. When the support pad and the extension adapter are coupled together, the first position-limiting posts are positioned in the position-limiting recessed portions and the hook portions are hooked onto the second position-limiting posts.
