  • Patent number: 11116578
    Abstract: Methods and system perform tool tracking during minimally invasive robotic surgery. Tool states are determined using triangulation techniques or a Bayesian filter from either or both non-endoscopically derived and endoscopically derived tool state information, or from either or both non-visually derived and visually derived tool state information. The non-endoscopically derived tool state information is derived from sensor data provided either by sensors associated with a mechanism for manipulating the tool, or sensors capable of detecting identifiable signals emanating or reflecting from the tool and indicative of its position, or external cameras viewing an end of the tool extending out of the body. The endoscopically derived tool state information is derived from image data provided by an endoscope inserted in the body so as to view the tool.

  • Publication number: 20210220078
    Abstract: A measurement system accesses first and second images captured respectively from first and second vantage points by first and second cameras included within a stereoscopic endo scope located at a surgical area associated with a patient. The measurement system receives user input designating a user-selected two-dimensional (ā€œ2Dā€) endpoint corresponding to a feature within the surgical area as represented in the first image, and identifies, based on the user-selected 2D endpoint, a matched 2D endpoint corresponding to the feature as represented in the second image. Based on the user-selected and matched 2D endpoints, the measurement system defines a three-dimensional (ā€œ3Dā€) endpoint corresponding to the feature within the surgical area. The measurement system then determines a distance from the 3D endpoint to an additional 3D endpoint corresponding to an additional feature within the surgical area. Corresponding systems and methods are also described.

  • Patent number: 10932649
    Abstract: A system may control an illuminator to illuminate a surgical site with non-white light and control a camera to capture light reflected from the surgical site. The camera may separate the captured light into a plurality of color components. The plurality of color components may be captured by the camera as a plurality of sets of pixels of a frame in a video stream, and each set of the plurality of sets of pixels may be in a different color channel of the camera. The system may further control, based on color component characteristics of the light captured by the camera, the illuminator to configure the non-white light such that each color channel of the camera has an about equal response to the light captured by the camera for a subsequently captured frame in the video stream.
