Abstract: Various embodiments of the invention provide systems and methods to assist or guide an arthroscopic surgery (e.g., surgery of the shoulder, knee or hip) or other surgical procedure by the placement of arbitrary landmarks in one or more locations in surgical field of view. The systems and methods comprise steps of receiving a video stream from an arthroscopic or other imaging device; receiving one or more sets of coordinates of one or more landmarks; overlaying the one or more landmarks on the video stream; and displaying the overlay on one or more display devices intraoperatively so as to be used by an operator during the arthroscopic or other medical procedure.

Abstract: Various embodiments provide probes, systems and methods to assist an arthroscopic, endoscopic or other surgical procedure by the placement of digital landmarks in selected locations in a surgical field of view. Many embodiments utilize a specialized probe having a tip with a spherical or other selected geometry of known dimensions to assist with placement of the landmark. The probe is placed at a desired anatomical location and imaged by an arthroscopic/endoscopic video camera. Embodiments may use a deep learning network to analyze the image data encoded by the camera, identify the probe and generate a segmented outline. Then, computer vision/shape fitting algorithms are used to generate a refined outline of the probe wherein the dimensions of the probe tip are used to improve the accuracy of the image including the tip. The improved tip image accuracy in turn improves the accuracy of the placement of a landmark using the tip.

Abstract: Various embodiments of the invention provide systems and methods to assist or guide an arthroscopic surgery or other surgical procedure e.g., surgery of the shoulder, knee or hip. The method comprises steps of receiving an image from an interventional imaging device, identifying a feature in the image using an image recognition algorithm, overlaying the features on a video feed on a display device and making recommendations or suggestions to an operator based on the identified feature in the image.

Abstract: Methods and apparatuses (e.g., devices and systems, including software) for automatically detecting a one or more features from a video (video file, video stream, etc.) of a surgical procedure. In some examples these methods and apparatuses may include identifying a stage of a surgical procedure (e.g., a surgical stage) of a video or portion of a video of a surgical procedure.

Abstract: Al-based systems and methods to annotate images and video from a surgical procedure may include extracting feature points (FP) from a still image (SI) of the procedure and each frame of a group of frames (GOF) from a procedure video and comparing FPs of the SI to FPs of each frame of the GOF to determine a match between the SI and a given frame from the video and a location in the video where the match occurred. Then the portion of the video containing the matched image is copied to create a video clip (VC) having a selected duration. Frames in the VC are analyzed to identify image features (IF), where a fidelity of IF identification is substantially unaffected when the IF is non-localizable or obscured. Then the SI and/or VC is annotated with information from the procedure, the information including or derived from the IFs.

Abstract: Various embodiments of the invention provide systems and methods to assist or guide an arthroscopic surgery (e.g., surgery of the shoulder, knee, hip or spine) or other surgical procedure by providing measurements intraoperatively. The systems and methods comprise steps of receiving a video stream from an arthroscopic imaging device; receiving one or more sets of coordinates of one or more points, paths, or area; calculating a length, a surface area, or a volume measurement based at least in part on the one or more sets of coordinates; overlaying the selected one or more sets of coordinates and the measurement on the video stream or on an expanded view of a region of surgery; and displaying the overlay on one or more display devices intraoperatively so as to be used by an operator during the arthroscopic procedure.
