Abstract

A method of operating a manipulator arm comprising a manipulator interface configured to removably couple with and transmit actuation force to a medical instrument includes mounting a cannula to a cannula mount coupled to the manipulator arm; mounting a medical instrument to the manipulator interface; inserting a shaft of the medical instrument through an entry guide mounted to the cannula; rotating the manipulator interface and the medical instrument relative to the cannula mount; and rotating the entry guide relative to the cannula mount about a longitudinal axis of the cannula.

Claims (49)

1. A method of operating a manipulator arm comprising a manipulator interface configured to removably couple with and transmit actuation force to a medical instrument, the method comprising:

mounting a cannula to a cannula mount coupled to the manipulator arm;

mounting a medical instrument to the manipulator interface;

inserting a shaft of the medical instrument through an entry guide mounted to the cannula;

rotating the manipulator interface and the medical instrument relative to the cannula mount; and

rotating the entry guide relative to the cannula mount about a longitudinal axis of the cannula.

2. The method of claim 1 ,

wherein the rotating of the medical instrument relative to the cannula mount causes the rotating of the entry guide relative to the cannula mount.

3. The method of claim 2 ,

wherein the rotating of the medical instrument relative to the cannula mount causes the shaft of the medical instrument to impart force to the entry guide to drive the rotating of the entry guide relative to the cannula.

4. The method of claim 1 ,

wherein rotating the manipulator interface and medical instrument comprises rotating the manipulator interface and the medical instrument about a roll axis that is aligned with a remote center of motion of the manipulator arm.

5. The method of claim 4 ,

wherein the remote center of motion is located along the cannula.

6. The method of claim 1 ,

wherein rotating the manipulator interface and medical instrument comprises rotating the manipulator interface and medical instrument about a roll axis aligned with the longitudinal axis of the cannula.

7. The method of claim 1 ,

wherein the manipulator arm comprises a plurality of manipulator interfaces including the manipulator interface.

8. The method of claim 7 ,

wherein rotating the manipulator interface relative to the cannula mount further comprises rotating the plurality of manipulator interfaces as a group relative to the cannula mount.

9. The method of claim 7 ,

wherein rotating the manipulator interface further comprises rotating the plurality of manipulator interfaces as a group around a common roll axis aligned with the longitudinal axis of the cannula.

10. The method of claim 7 ,

wherein the entry guide comprises a plurality of channels and inserting the medical instrument through the entry guide comprises inserting the medical instrument through one of the plurality of channels.

11. The method of claim 10 ,

wherein each of the plurality of channels of the entry guide is radially offset from the longitudinal axis of the cannula.

12. The method of claim 1 ,

wherein inserting the medical instrument through the entry guide comprises inserting the medical instrument through a channel of the entry guide, the channel being radially offset from the longitudinal axis of the cannula.

13. A method, comprising:

moving a cannula mount from a retracted position to an extended position by pivoting an extension arm of the cannula mount relative to a link of a manipulator arm, the extension arm being coupled to the link;

mounting a cannula to a mounting mechanism of the cannula mount, the mounting mechanism at a free end portion of the extension arm;

mounting a proximal portion of a medical instrument to a manipulator interface rotatably coupled to the link of the manipulator arm, the manipulator interface configured to transmit actuation force to the medical instrument; and

inserting a distal portion of the medical instrument through the cannula.

14. The method of claim 13 ,

wherein in the extended position of the cannula mount, a remote center of motion of the manipulator arm is located along the cannula mounted to the mounting mechanism.

15. The method of claim 13 ,

wherein inserting the distal portion of the medical instrument through the cannula comprises inserting the distal portion of the medical instrument through an entry guide mounted to the cannula.

16. The method of claim 15 , further comprising:

rotating the manipulator interface, the medical instrument, and the entry guide relative to the cannula mount about a longitudinal axis of the cannula.

17. The method of claim 16 ,

wherein rotating the medical instrument relative to the cannula mount causes the rotating of the entry guide relative to the cannula mount.

18. The method of claim 15 ,

wherein the manipulator arm comprises a plurality of manipulator interfaces including the manipulator interface, and

wherein inserting the distal portion of the medical instrument through the entry guide comprises inserting the distal portion of the medical instrument through one of a plurality of channels of the entry guide arranged to receive respective distal portions of other respective medical instruments in a mounted state at the respective manipulator interfaces, each of the plurality of channels being radially offset from a longitudinal axis of the cannula.

19. The method of claim 13 ,

wherein the manipulator arm comprises a plurality of manipulator interfaces including the manipulator interface, and

wherein the method further comprises rotating the plurality of manipulator interfaces as a group relative to the cannula mount.

20. The method of claim 18 ,

wherein, in the extended position of the cannula mount, the plurality of manipulator interfaces rotate as a group around a common roll axis aligned with a longitudinal axis of the cannula mounted to the mounting mechanism.
