    Abstract: An adjustable height lift platform for a surgeon to stand on while he or she performs a surgical procedure that is comfortably and beneficially performed at a desired height. The lift platform comprises a base platform having a lower surface that rests on the floor, an upper platform having an upper surface on which the surgeon stands and a lifting mechanism that interconnects the base and upper platforms to raise and lower the upper platform. The lifting mechanism has a first linkage assembly pivotally connected to a second linkage assembly, slotted tracks at each of the base and upper platforms, cam followers associated with the linkage assemblies that are received in the slotted tracks and linear actuators that engage the linkage assemblies to pivot them in a scissor-like manner to raise and lower the upper platform. Preferably, a foot operated switch controls the movement and positioning of the upper platform.
