  • Patent number: 12605209
    Abstract: A minimally invasive surgical system is disclosed including a processor coupled to a stereoscopic endoscope and a stereoscopic video display device. The processor generates an operative image of an anatomic structure in the surgical site, overlays the operative image onto the captured stereo video images for display on the stereoscopic video display device, generates and overlays a pointer onto the operative image or the captured stereo video images to display the pointer on the stereoscopic video display device with a three dimensional appearance, and switches between a first mode for input devices of a surgeon console used to couple motion into surgical instruments and a second mode used to control an interactive graphical user interface to allow interactions with the pointer and the operative image in three dimensions using input devices having at least three degrees of freedom.

  • Patent number: 11928838
    Abstract: A calibration platform may obtain measurements for aligning a real-world coordinate system and a display coordinate system. For example, the calibration platform may display, via an optical see-through head-mounted display (OST-HMD), a three-dimensional virtual object and receive, from a positional tracking device, information that relates to a current pose of a three-dimensional real-world object to be aligned with the three-dimensional virtual object. The calibration platform may record a three-dimensional position of a plurality of points on the three-dimensional real-world object based on the current pose of the three-dimensional real-world object, based on an indication that the plurality of points on the three-dimensional real-world object respectively corresponds with a plurality of points on the three-dimensional virtual object.

  • Patent number: 11861062
    Abstract: A calibration platform may display, via an optical see-through head-mounted display (OST-HMD), a virtual image having at least one feature. The calibration platform may determine, based on information relating to a gaze of a user wearing the OST-HMD, that the user performed a voluntary eye blink to indicate that the at least one feature of the virtual image appears to the user to be aligned with at least one point on the three-dimensional real-world object. The calibration platform may record an alignment measurement based on a position of the at least one point on the three-dimensional real-world object in a real-world coordinate system based on a time when the user performed the voluntary eye blink. Accordingly, the alignment measurement may be used to generate a function providing a mapping between three-dimensional points in the real-world coordinate system and corresponding points in a display space of the OST-HMD.

  • Patent number: 10531828
    Abstract: The present invention is directed to a method and system for photoacoustic imaging for guiding medical procedures. A transducer is placed near the site of the procedure. The optical fiber, coupled to an electromagnetic source, such as a laser, is attached to a medical device. During the procedure, the device and optical fiber are inserted into the procedure site where the optical fiber illuminates the procedure site, which has a thickness of approximately 2 mm. Photoacoustic images are acquired to visualize the procedure site as the procedure is proceeding in order to provide real-time guidance. This system is applicable to multiple surgical and interventional procedures, such as transsphenoidal surgery.
