Abstract
A method of using a surgical robotic system includes positioning a surgical instrument in a body cavity, the surgical instrument being one that is carried by a robotic arm. An image of an operative site within the body cavity is captured and used to identify a structure to be avoided. A user uses an input device to give input to the robotic system to cause movement of the surgical instrument at the site. The system determines determining whether the surgical instrument is approaching contact with the structure and, if it is, initiates an avoidance step.
Claims5
A method of using a surgical robotic system, comprising the steps of:
- positioning a surgical instrument in a body cavity, the surgical instrument carried by a robotic arm;
- capturing an image of an operative site within the body cavity;
- using the image, identifying a structure to be avoided;
- using an input device to give input to the robotic system to cause movement of the surgical instrument at the site;
- automatically determining whether the surgical instrument is approaching contact with the structure;
- and
- initiating an avoidance step if the system determines the surgical instrument is approaching contact with the structure.
A method of identifying structures within a body cavity using structured light techniques, the structured light techniques are carried out using structured light illumination using light sources on a trocar,
A trocar adapted to illuminate body tissue in a pattern for use in structured light techniques.
