Abstract: Provided are a surgical table and a supporting structure. The surgical table includes a supporting platform, a holding component, a supporting assembly, a releasing component, and a limiting component. The holding component is rotatably installed on the supporting platform in a vertical direction. The supporting assembly is provided at the bottom of the holding component, and includes a first installation end rotatably connected to the supporting platform and a second installation end movably connected to the holding component. A release button is provided at the second installation end of the supporting assembly, and the releasing component is movably connected to the second installation end When the holding component overturns relative to the supporting platform as the holding component is acted upon by a force, the limiting component drives the releasing component to move relative to the second installation end to trigger the release button.
