1. An instrument access system for robotic surgery, comprising:
a robotically controlled surgical instrument;
an access port including:
a longitudinal axis;
a proximal ring-shaped base for location externally of an opening in a body;
a distal ring for location within the opening in the body; and
a retraction sleeve extending between the proximal base and the distal ring; and
a proximal extension forming cavity proximal to the proximal ring-shaped base, the proximal extension including:
a cap located at a proximal end of the proximal extension, the cap including
a robot-instrument-receiving main port having a first diameter and being in a fixed location on the cap, the robot-instrument-receiving main port configured to receive the robotically controlled surgical instrument, and
an auxiliary port with a second diameter smaller than the first diameter of the robot-instrument-receiving main port;
a second auxiliary port, wherein the auxiliary port is rotatable about the robot-instrument-receiving main port without rotating the second auxiliary port; and
a sidewall between the ring-shaped base and cap, wherein the sidewall includes a sleeve portion, wherein a shortening of a length of the retraction sleeve between the proximal base and the distal ring does not require movement of the sidewall.
