1. A surgical table comprising:
a base for standing on a floor;
a column of adjustable height mounted on and extending from the base;
a tabletop providing a patient support surface;
a movable framework mounted between the tabletop and the column for enabling at least a part of the tabletop to be rotatable about a trend axis, the trend axis extending in a transverse direction across the tabletop; and
an actuator mechanism coupled to the movable framework and arranged to raise and lower the movable framework relative to the column and to raise and lower the trend axis and to rotate the movable framework about the trend axis, wherein the actuator mechanism comprises first and second actuators, the first actuator being connected to a first portion of the movable framework by a first pivot coupling between the actuator mechanism and the movable framework, and the second actuator being connected to a second portion of the movable framework by a second pivot coupling between the actuator mechanism and the movable framework, the first and second portions being mutually spaced and located on opposite sides of the trend axis; and
a control mechanism arranged to be operable to control the actuator mechanism to cause the trend axis to be movable between first, second and third configurations, wherein in the first configuration the trend axis is aligned with a physical axis of the first pivot coupling, in the third configuration the trend axis is aligned with a physical axis of the second pivot coupling, and in the second configuration the trend axis is a virtual axis located between the physical axes of both of the first and second pivot couplings, wherein the control mechanism comprises a speed and direction controller for controlling the speed and movement direction of the first and second actuators, the controller being arranged to be operable, for achieving translational motion of the trend axis between the first, second and third configurations, independently to control the first and second actuators and/or independently to control the speed and movement direction of each of the first and second actuators.
