Laparoscopic ultrasound robotic surgical system
A LUS robotic surgical system is trainable by a surgeon to automatically move a LUS probe in a desired fashion upon command so that the surgeon does not have to do so manually during a minimally invasive surgical procedure. A sequence of 2D ultrasound image slices captured by the LUS probe according to stored instructions are processable into a 3D ultrasound computer model of an anatomic structure, which may be displayed as a 3D or 2D overlay to a camera view or in a PIP as selected by the surgeon or programmed to assist the surgeon in inspecting an anatomic structure for abnormalities. Virtual fixtures are definable so as to assist the surgeon in accurately guiding a tool to a target on the displayed ultrasound image.
1. A method for providing robotic assisted laparoscopic ultrasound, comprising:
capturing an ultrasound image using an ultrasound probe disposed at a position and orientation;
storing information of the position and orientation;
generating a clickable thumbnail of the ultrasound image;
associating the stored position and orientation with the clickable thumbnail;
displaying the clickable thumbnail on a display screen;
storing a current ultrasound probe position and orientation upon detection of a start of training indication;
moving the ultrasound probe; and
periodically storing ultrasound probe positions and orientations as the ultrasound probe is moving to define a trajectory of positions and orientations until detection of an end of training indication.
2. The method according to claim 1 , wherein the start and end of training indications are generated by user voice commands.
3. The method according to claim 1 , wherein the start and end of training indications are generated by user selections using a graphical user interface.
4. The method according to claim 1 , wherein the start and end of training indications are generated by positions of one or more switch mechanisms.
5. The method according to claim 1 , further comprising: associating the trajectory of positions and orientations with a first voice command.
6. The method according to claim 5 , further comprising: causing the ultrasound probe to move along the trajectory of positions and orientations upon detection of the first voice command.
7. The method according to claim 5 , further comprising: causing the ultrasound probe to move back and forth along the trajectory of positions and orientations upon detection of the first voice command and until detection of a second voice command.
8. The method according to claim 1 , wherein the clickable thumbnail is associated with a position and orientation of the ultrasound probe that are included as a pair in the trajectory of positions and orientations, and
the method further comprising: associating the trajectory of positions and orientations with the clickable thumbnail.
9. The method according to claim 8 , further comprising: causing the ultrasound probe to move along the trajectory of positions and orientations upon detection of the clickable thumbnail having been clicked upon and until a stop indication is received.
10. The method according to claim 1 , further comprising: associating the trajectory of positions and orientations with a first switch position.
11. The method according to claim 10 , further comprising: causing the ultrasound probe to move along the trajectory of positions and orientations upon detection of a switch being in the first switch position and until detection of the switch being in a second switch position.
12. A method for providing robotic assisted laparoscopic ultrasound, comprising:
capturing an ultrasound image using an ultrasound probe disposed at a position and orientation;
storing information of the position and orientation;
generating a clickable thumbnail of the ultrasound image;
associating the stored position and orientation with the clickable thumbnail;
displaying the clickable thumbnail on a display screen;
receiving information of a user having clicked on the clickable thumbnail; and
causing the ultrasound probe to be disposed at the position and orientation associated with the clicked upon clickable thumbnail.
