Disclosed herein are systems and devices for performing computer-aided surgical navigation. Specifically, a system for augmented reality assisted trauma fixation, which displays various views of one or more tracked items, including a guide device, a fixation plate, a surgical tracking device, and an augmented reality display. The guide device having a tip, a handle, and a fixation guide. The fixation plate having at least one aperture designed to receive the tip of the guide. The surgical tracking device configured to track one or more trackable objects associated with the guide, fixation plate, and display, and thereby calculate a location of a fixation device, such as a screw, relative to the fixation plate.

A computer-implemented medical visualization method includes identifying a three-dimensional model of an anatomical item of a particular mammal; automatically identifying an open path in three-dimensional space through the anatomical item; fitting a smooth curve to the open path; and displaying the anatomical item and a visual representation of the smooth curve to a user on a three-dimensional imaging system.

A trajectory guidance alignment system configurable to receive input data from an image, interactively track at least one user position, interactively track a tool position, automatically generate output data by way of data transformation using at least one of the input data, the user position data, and the tool position data, and transmit the output data to the display of a navigation system for rendering a real-time interactive navigation view corresponding to a surgical view for facilitating navigation of a medical procedure.

Devices and methods for performing a surgical step or surgical procedure with visual guidance using an optical head mounted display are disclosed.

The present invention relates to user guiding during X-ray imaging. In order to provide further guidance during X-ray imaging, a guiding device (10) for visual guidance during X-ray imaging is provided. The guiding device (10) comprises a camera arrangement (12), a display arrangement (14) and a housing structure (16). The housing structure comprises a housing (18) of an X-ray imaging system for housing an X-ray source or an X-ray detector. Further, the camera arrangement is configured to capture image data of a region of interest of a subject in front of the housing. Furthermore, the display arrangement is configured to present the captured image data as a live presentation of the region of interest. Still further, the camera arrangement is mounted to the housing on a first side (20) of the housing, and the display arrangement is mounted to the housing on a second side (22) of the housing, the second side being at least one of the group of lateral and opposite to the first side. Hence, the display arrangement is configured to provide a presentation comprising live images from the first side to a user located on the second side of the housing.

The invention relates to video glasses and a stereoscopic microscope with video glasses for use in microsurgical procedures. The video glasses comprise a support device configured to fasten the video glasses to a head of a user, an image display unit for outputting images, a joint with a rotational axis, which connects the support device with the image display unit rotationally about the rotational axis between an operating position, in which the image display unit is arranged in front of the eyes of the user and images can be displayed to the user, and a rest position, in which the image display unit is arranged upwards out of the visual field of the user, and a locking device. The locking device comprises a latching device and a catch arranged to let the latching device upon rotation in a rotational direction about the rotational axis engage the catch in a holding position and to release the latching device from the catch upon further rotation in the rotational direction, and wherein a rotation in the opposite rotational direction beyond the holding position is impeded as long as the latching device is engaged in the catch.

A camera tracking system for computer assisted navigation during surgery operatively determines a first pose of a second extended-reality (XR) headset relative to stereo tracking cameras located on a first XR headset based on first tracking information from the stereo tracking cameras. The camera tracking system determines a second pose of eyes of a user wearing the second XR headset relative to the stereo tracking cameras located on the first XR headset based on second tracking information from the stereo tracking cameras. The camera tracking system also calibrates an eye-to-display relationship defining pose of the eyes of the user wearing the second XR headset to a display device of the second XR headset based on the determined first and second poses. The camera tracking system also controls where symbols are displayed on the display device of the second XR headset based on the eye-to-display relationship.

A virtual representation of an operating room is generated based on robot information and sensing of the OR with depth cameras. One of the depth cameras is integrated with a portable electronic device, operated by a local user in the operating room. The virtual representation of the OR is communicated to the virtual reality headset, with three-dimensional point cloud data. A virtual reality environment is rendered to a display of the virtual reality headset, operated by a remote user. A virtual representation of the remote user is rendered in augmented reality to a display of the portable electronic device.

Described herein are systems, methods, and techniques for spatially-aware displays for computer-assisted interventions. A Fixed View Frustum technique renders computer images on the display using a perspective based on a virtual camera having a field-of-view facing the display and automatically updates the virtual position of the virtual camera in response to adjusting the pose of the display. A Dynamic Mirror View Frustum technique renders computer images on the display using a perspective based on a field-of-view of a virtual camera that has a virtual position behind the display device. The virtual position of the virtual camera is dynamically updated in response to movement of a user's viewpoint located in front of the display device. Slice visualization techniques are also described herein for use with the Fixed View Frustum and Dynamic Mirror View Frustum techniques.

An offsite device for remote augmented reality communication for guided surgery configured to receive, by an offsite device, a plurality of representations of a plurality of frames and a plurality of indices, wherein the plurality of indices includes at least a first frame index and at least a second frame index, display, by the offsite device and to an offsite surgeon, a second frame of the second frame index, input, by the offsite device, an illustration from the offsite surgeon, wherein the illustration is drawn on the second frame, register, by the offsite device, the illustration to the second frame, wherein registering produces registration data, and transmit, by the offsite device, the illustration and the registration data.
