1. An instrument assembly support apparatus for supporting an instrument assembly relative to a patient positioned adjacent to an external frame, comprising: a base fixedly mountable onto the external frame;a pivot assembly mounted relative to the base and including a housing, a first pivot structure pivotably mounted to the housing and fixedly mounted to the base, and a second pivot structure pivotably mounted to the housing, the housing being configured to pivot relative to the first pivot structure and the external frame about a first pivot axis, and the second pivot structure being configured to pivot relative to the housing about a second pivot axis, wherein the housing includes two opposed and spaced side portions and a base portion connecting the two side portions to define a gap between the two side portions, the second pivot structure being disposed within the gap with at least one surface of the second pivot structure extending through the gap over a range of pivot positions about the second pivot axis;an arm assembly extending along a longitudinal axis and having a first portion mounted to the at least one surface of the second pivot structure for pivoting relative to the housing, and a second portion extending distally of the first portion;a support assembly mounted to the second portion and configured to support the instrument assembly on the arm assembly; anda first lock assembly mounted to the housing and configured to be remotely actuated to lock the first pivot structure relative to the housing, the first lock assembly including first and second opposing planar faces intersected by the first pivot axis, a first stop, and a biasing mechanism, wherein the first face is mounted to the first pivot structure, wherein the second face is disposed to move normal to the first face, wherein the first stop is configured to prevent pivoting of the second face about the first pivot axis, and wherein the biasing mechanism is configured to selectively bias the second face toward the first face. 2. The instrument assembly support apparatus of claim 1, further comprising a second lock assembly mounted to the housing and configured to be remotely actuated to lock the second pivot structure relative to the housing, wherein the second lock assembly includes third and fourth opposing planar faces, wherein the second pivot structure includes fifth and sixth opposing planar faces, and wherein the third and fourth faces are disposed to move normal to the fifth and sixth faces. 3. The instrument assembly support apparatus of claim 2, wherein the biasing mechanism is configured to selectively bias the third and fourth faces toward the fifth and sixth faces, respectively. 4. The instrument assembly support apparatus of claim 3, wherein the biasing mechanism includes a control device connected to a pressurized gas supply, wherein the control device is configured to selectively provide pressurized gas to the first lock assembly to urge the second face toward the first face. 5. The instrument assembly support apparatus of claim 4, wherein the control device is configured to selectively provide the pressurized gas to the second lock assembly to urge the third and fourth faces toward the fifth and sixth faces, respectively. 6. The instrument assembly support apparatus of claim 1, wherein the first pivot structure includes one of at least a first pin and a first groove, and the housing includes the other of the at least a first pin and a first groove, the at least a first pin being received in the first groove and the first groove being configured to limit pivoting of the housing relative to the first pivot structure within a first predetermined number of degrees. 7. The instrument assembly support apparatus of claim 6, wherein the second pivot structure includes one of at least a second pin and a second groove, and the housing includes the other of the at least a second pin and a second groove, the at least a second pin being received in the second groove and the second groove being configured to limit pivoting of the second pivot structure relative to the housing within a second predetermined number of degrees. 8. The instrument assembly support apparatus of claim 1, wherein the base includes a grip assembly and a connector assembly, the grip assembly including a grip and an elongate support member, the grip being configured to selectively grip the external frame and the elongate support member extending away from the grip, the connector assembly being attached to the elongate support member and configured to selectively receive the first pivot structure. 9. The instrument assembly support apparatus of claim 8, where the external frame includes a rail that extends along a rail axis, wherein the first pivot structure is selectively received in the connector assembly such that the first pivot structure extends along an axis parallel to the rail axis.
