1. A method comprising:
advancing a distal end of a straight first rigid surgical instrument body tube through a first channel of a guide tube, the distal end of the first rigid surgical instrument body tube being coupled to an end component, wherein as the distal end of the first rigid surgical instrument body tube advances through the guide tube, a portion of the first rigid surgical instrument body tube proximal to and outside the guide tube is resiliently bent; and
advancing a second straight rigid surgical instrument body tube of a second surgical instrument through a second channel of the guide tube, a portion of the second rigid surgical instrument body tube proximal to and outside the guide tube being resiliently bent, the guide tube being coupled to a platform, each of the first and second surgical instruments being coupled to the platform by a different teleoperated manipulator assembly, and the platform being coupled to a robotic manipulator arm of a patient side support system.

rotating the guide tube around a remote center point.
3. The method of claim 2 :
wherein a guide tube longitudinal axis is defined through proximal and distal ends of the guide tube; and
wherein the rotating the guide tube comprises rotating the guide tube around an axis perpendicular to the guide tube longitudinal axis.
4. The method of claim 2 :
wherein a guide tube longitudinal axis is defined through proximal and distal ends of the guide tube; and
wherein the rotating the guide tube comprises rotating the guide tube around the guide tube longitudinal axis.
5. A method of operating a patient side support system comprising:
advancing a first distal portion of a first straight rigid surgical instrument body tube of a first surgical instrument through a first channel of a guide tube, with a first proximal portion of the first rigid surgical instrument body tube being resiliently bent between a first transmission mechanism of the first surgical instrument and a proximal end of the guide tube as the first distal portion of the first rigid surgical instrument body tube advances through the first channel of the guide tube;
wherein the first transmission mechanism is coupled to the first proximal portion of the first rigid surgical instrument body tube;
wherein a first surgical end effector is coupled to the first distal portion of the first rigid surgical instrument body tube and is coupled to the first transmission mechanism;
wherein the guide tube is coupled to a platform;
wherein the first transmission mechanism is coupled to a first teleoperated manipulator assembly of a plurality of teleoperated manipulator assemblies; and
wherein the plurality of teleoperated manipulator assemblies is coupled to the platform; and
wherein the platform is coupled to a robotic manipulator arm of the patient side support system.
6. The method of claim 5 , further comprising:
moving the first surgical end effector in at least one of the six Cartesian degrees of freedom independently of degrees of freedom of the guide tube.
7. The method of claim 6 :
wherein the moving the first surgical end effector further comprises:
applying a force on the first transmission mechanism by the first teleoperated manipulator assembly of the plurality of teleoperated manipulator assemblies, wherein the force on the first transmission mechanism moves the first surgical end effector.
8. The method of claim 6 , further comprising:
moving the first surgical end effector in a seventh degree of freedom that is independent of the six Cartesian degrees of freedom.
9. The method of claim 8 :
wherein the moving the first surgical end effector in the seventh degree of freedom further comprises:
applying a force on the first transmission mechanism by the first teleoperated manipulator assembly of the plurality of teleoperated manipulator assemblies, wherein the force on the first transmission mechanism moves the first surgical end effector in the seventh degree of freedom.
10. The method of claim 6 , wherein the moving the first surgical end effector comprises:
moving a stereoscopic image capture component.
11. The method of claim 5 , wherein the advancing the first distal portion of the first rigid surgical instrument body tube further comprises:
moving the one teleoperated manipulator assembly of the plurality of teleoperated manipulator assemblies.
12. The method of claim 11 , wherein the moving the one teleoperated manipulator assembly of the plurality of teleoperated manipulator assemblies further comprises:
actuating a linear actuator coupled to a housing of the first transmission mechanism.
13. The method of claim 5 , further comprising:
moving the platform in at least one of the six Cartesian degrees of freedom; and
wherein the moving the platform moves the guide tube.
14. The method of claim 13 , wherein the moving the platform further comprises:
moving the robotic manipulator arm coupled to the platform.
15. The method of claim 14 , further comprising:
advancing a second distal portion of a second rigid surgical instrument body tube of a second surgical instrument through a second channel of the guide tube, with a second-proximal portion of the second rigid surgical instrument body tube being resiliently bent between a second transmission mechanism and the proximal end of the guide tube as the second distal portion of the second rigid surgical instrument body tube advances through the second channel of the guide tube, while the first distal portion of the first rigid surgical instrument body tube is inserted in the first channel of the guide tube;
wherein a second transmission mechanism is coupled to the second proximal portion of the second rigid surgical instrument body tube; and
wherein a second surgical end effector is coupled to the second distal portion of the second rigid surgical instrument body tube and is coupled to the second transmission mechanism; and
wherein the second transmission mechanism is coupled to a second teleoperated manipulator assembly of the plurality of teleoperated manipulator assemblies.
16. The method of claim 5 , further comprising:
moving the first surgical end effector in at least five of the six Cartesian degrees of freedom independently of degrees of freedom of the guide tube.
17. The method of claim 5 , further comprising:
moving the platform in at least four of the six Cartesian degrees of freedom.
