1. A patient side support system comprising:
- a base;
a first link coupled to the base at a first rotational joint, the first rotational joint having a rotational axis around which the first rotational joint rotates;
a platform supported by the first link, the platform having a roll axis around which the platform rotates;
a plurality of manipulator assemblies coupled to the platform;
a plurality of instruments, each of the plurality of instruments being coupled to a different one of the plurality of manipulator assemblies, each of the plurality of instruments including a body and a shaft, the shaft extending from the body; and
a rigid guide tube common to the plurality of instruments;
wherein a first part of the shaft of each individual one of the plurality of instruments extends between the body and the rigid guide tube, and a second part of the shaft of each individual one of the plurality of instruments extends through the rigid guide tube;
wherein the rigid guide tube is positioned so that a remote center of motion point of the platform is located on the rigid guide tube, the remote center of motion point being adjacent a location at which the rigid guide tube is configured to enter a patient;
wherein the rotational axis of the first rotational joint is vertically aligned with and extends through the remote center of motion point;
wherein the roll axis of the platform is aligned with and extends through the remote center of motion point; and
wherein the first part of the shaft of one or more of the plurality of instruments being resiliently bent between the body of the one of the plurality of instruments and the rigid guide tube.
