Robotic surgical table with relatively high resonant frequency structure to reduce efficiency of energy transmission between attached robotic arms

A surgical table, comprising:

• a support column having an upper end that has a periphery in a plane transverse to a vertical axis of the support column;
• a table top;
• a pivot assembly coupling the table top to the support column, the pivot assembly including:
• a support flange fixedly coupled to and disposed on top of the upper end of the support column and having a horizontal top surface that extends outside the periphery of the upper end of the support column,
• a primary load support, a first actuator, and a second actuator that are each mounted on the horizontal top surface,
• wherein the primary load support has an upper end having a pivot joint coupled to the table top,
• wherein the first actuator has an upper end having a pivot joint coupled to the table top, and is variable in length in a vertical direction with respect to the vertical axis to pivot the table top about the pivot joint of the primary load support along at least a lateral pivot axis with respect to the table top that runs through the pivot joint of the primary load support,
• wherein the second actuator has an upper end having a pivot joint coupled to the table top, and is variable in length in the vertical direction to pivot the table top about the pivot joint of the primary load support along at least a longitudinal pivot axis with respect to the table top that runs through the pivot joint of the primary load support,
• wherein the first and second actuators maintain a fixed vertical orientation with respect to the vertical axis while at least one of the first and second actuators varies in length in the vertical direction,
• wherein the primary load support, the first actuator, and the second actuator are arranged in a triangle on the horizontal top surface such that each of the primary load support, the first actuator, and the second actuator are positioned at a vertex of the triangle, and
• wherein a first side of the triangle from the first actuator to the primary load support extends along the longitudinal pivot axis and a second side of the triangle from the second actuator and the primary load support extends along the lateral pivot axis.

An apparatus, comprising:

• a pivot assembly that is coupled to a surgical table that has a table top, a support column, and a base, the pivot assembly coupling the table top to the support column that extends upward from the base, the support column having an upper end that has a periphery in a plane transverse to a vertical axis of the support column,
• the pivot assembly having:
• a support flange attached to and disposed on top of the upper end of the support column and having a horizontal top surface that extends outside the periphery of the upper end of the support column, and
• a primary load support, a first actuator, and a second actuator that are each mounted on the horizontal top surface,
• wherein the primary load support has an upper end having a pivot joint coupled to the table top,
