  • Patent number: 9005112
    Abstract: The present invention is directed to an articulate minimally invasive surgical endoscope with a flexible wrist having at least one degree of freedom. When used with a surgical robot having a plurality of robot arms, the endoscope can be used with any of the plurality of arms thereby allowing the use a universal arm design. The endoscope in accordance to the present invention is made more intuitive a to a user by attaching a reference frame used for controlling the at least one degree of freedom motion to the flexible wrist for wrist motion associated with the at least one degree of freedom. The endoscope in accordance to the present invention attenuates undesirable motion at its back/proximal end by acquiring the image of the object in association with the at least one degree of freedom based on a reference frame rotating around a point of rotation located proximal to the flexible wrist.

  • Publication number: 20150025392
    Abstract: An apparatus is configured to show telestration in 3-D to a surgeon in real time. A proctor is shown one side of a stereo image pair, such that the proctor can draw a telestration line on the one side with an input device. Points of interest are identified for matching to the other side of the stereo image pair. In response to the identified points of interest, regions and features are identified and used to match the points of interest to the other side. Regions can be used to match the points of interest. Features of the first image can be matched to the second image and used to match the points of interest to the second image, for example when the confidence scores for the regions are below a threshold value. Constraints can be used to evaluate the matched points of interest, for example by excluding bad points.

  • Publication number: 20150005622
    Abstract: In one embodiment of the invention, a method is disclosed to locate a robotic instrument in the field of view of a camera. The method includes capturing sequential images in a field of view of a camera. The sequential images are correlated between successive views. The method further includes receiving a kinematic datum to provide an approximate location of the robotic instrument and then analyzing the sequential images in response to the approximate location of the robotic instrument. An additional method for robotic systems is disclosed. Further disclosed is a method for indicating tool entrance into the field of view of a camera.

  • Publication number: 20130245375
    Abstract: In one embodiment of the invention, a method for a minimally invasive surgical system is disclosed. The method includes capturing and displaying camera images of a surgical site on at least one display device at a surgeon console; switching out of a following mode and into a masters-as-mice (MaM) mode; overlaying a graphical user interface (GUI) including an interactive graphical object onto the camera images; and rendering a pointer within the camera images for user interactive control. In the following mode, the input devices of the surgeon console may couple motion into surgical instruments. In the MaM mode, the input devices interact with the GUI and interactive graphical objects. The pointer is manipulated in three dimensions by input devices having at least three degrees of freedom. Interactive graphical objects are related to physical objects in the surgical site or a function thereof and are manipulatable by the input devices.

  • Publication number: 20130046137
    Abstract: A surgical instrument has a distal end portion with an outer surface with an outer radius. One or more image capture elements are movably mounted in the distal end portion. In a first state, the one or more image capture elements are un-deployed. In the first state, a surface having an aperture of at least one of the one or more image capture elements is enclosed within the outer surface of the surgical instrument so that the surface having the aperture does not extend beyond the outer surface. In a second state, the one or more image capture elements are deployed. In the second state the surface having the aperture of the at least one of the one or more image capture elements extends beyond the outer surface.

  • Patent number: 8228368
    Abstract: An illumination channel, a stereoscopic optical channel and another optical channel are held and positioned by a robotic surgical system. A first capture unit captures a stereoscopic visible image from the first light from the stereoscopic optical channel while a second capture unit captures a fluorescence image from the second light from the other optical channel. An intelligent image processing system receives the captured stereoscopic visible image and the captured fluorescence image and generates a stereoscopic pair of fluorescence images. An augmented stereoscopic display system outputs a real-time stereoscopic image comprising a three-dimensional presentation of a blend of the stereoscopic visible image and the stereoscopic pair of fluorescence images.
