In an embodiment, the present disclosure relates to a system for performing arthrography, comprising a physical grid positioned on skin of a patient proximate a region of interest of a joint on which the arthrography is to be performed, and processing circuitry configured to receive medical images of the patient, the received medical images being acquired by a same imaging modality and having visible a portion of the physical grid, determine a trajectory between an entry point identified on the physical grid and a target point identified within the region of interest of the joint, and generate a target entry angle based on the determined trajectory between the identified entry point and the identified target point, wherein a needle guide device, configured to releasably-hold a needle, is positionable according to the identified entry point and target entry angle.

A technique of providing user guidance for surgical navigation is provided. A method implementation of the technique includes obtaining a predetermined spatial relationship between an optical tracking pattern and a through-hole extending through an implant, obtaining image data of the optical tracking pattern acquired by an imaging unit attached to a surgical instrument, obtaining a spatial relationship between the surgical instrument and the imaging unit at a point in time when the image data have been acquired, determining a spatial relationship between the surgical instrument and the through-hole, obtaining a plurality of predefined spatial relationships between the surgical instrument and the through-hole, and triggering simultaneous display of an indication of the plurality of predefined spatial relationships and an indication of the spatial relationship between the surgical instrument and the through-hole.

Methods, non-transitory computer readable media, serial monitor devices, fiducial tracking knee braces devices, and systems that facilitate generation of improved three-dimensional models from two-dimensional multi-planar images are disclosed. With this technology, correspondence of a patient's knee angle is substantially maintained across x-ray images to improve fiducial-marker-to-bone relationships within the images and facilitate improved scaling and registration of the images to generate a three-dimensional model of the knee. In particular, orientation sensor(s) attached to an improved knee brace device allows a user to substantially match the position of the knee across anterior/posterior and lateral x-ray images so that the images can be scaled and oriented more effectively, resulting in more accurate three-dimensional models and improved preoperative planning for patients.

The present disclosure relates generally to a surgical system. The surgical system comprises one or more surgical instrument assemblies and a surgical navigation system. The surgical instrument assemblies comprises a tracking device capable of being tracked by the surgical navigation system. The surgical system is also configured to allow the user to define one or more alert zones relative to anatomical structures of the patient and/or a surgical pathway. The surgical system further comprises an alert device in communication with the surgical navigation system, such that the alert device is configured to provide a user-perceptible alert to the surgeon or medical professional based on the position of the surgical instrument, as determined by the surgical navigation system, relative to the defined alert zones and/or surgical pathway.

Systems, methods, and devices are provided for assisting or performing guided interventional procedures using specialized catheters and inserts. A bend altering device is introduced into a conduit in an organ causing it to take on a tortuous path and to assist in its visualization. A scan is performed of a patient's anatomy to identify targets critical structures and the path of the conduit. A bend altering device containing position indicating elements is placed into the conduit in the same path as before the scan. During a procedure, the pre-procedure scans may be registered to the patient using the location of the position indicating elements in the conduit. This registration may be used in an intervention to guide instruments and templates to obtain diagnostic information or provide therapy to the targets identified in the scans.

A camera tracking system is disclosed for computer assisted navigation during surgery. The camera tracking system is configured to identify a reference array tracked by a set of tracking cameras attached to an extended reality (XR) headset, and determine whether the reference array is registered as being paired with characteristics of one of a plurality of surgical tools defined in a surgical tool database. The camera tracking system is further configured to, based on the reference array being determined to not be registered and receiving user input, register the reference array to be paired with characteristics of one of the plurality of surgical tools selected based on the user input. The camera tracking system is further configured to provide a representation of the characteristics to a display device of the XR headset for display to the user.

Multimodality markers for delineation of a region of interest (ROI) within a patient's body are disclosed. The markers may comprise a hermetic bio-compatible container and an external element that is associated with the hermetic bio-compatible container. A unique collective identification (ID) is assigned to each of the markers. The collective ID can comprise a visible component seen on an imaging system and an electronic component stored in a microelectronic chip and embedded within the hermetic bio-compatible container.

A surgical instrument is disclosed having an elongated body portion having a proximal end and a distal end. The body portion is formed from a plastically deformable material such that the body portion can be bent between the proximal and distal ends from a first configuration to a second bent configuration and maintains the bent configuration. A flexible circuit having at least a pair of lead wires disposed around the body portion. The pair of lead wires are configured to conform to the bent configuration of the body portion such that they do not break during bending of the body portion. A tracking device adapted to cooperate with a navigation system to track the distal end of the instrument is coupled to the flexible circuit.

A surgical system includes a detector that includes an array of pixels configured to detect light reflected by a surgical device and generate a first signal. The first signal includes a first dataset representative of a visible image of the surgical device. The surgical system also includes a processor configured to receive the first signal and a second signal representative of one or more operating parameters of the surgical device. The processor is also configured to generate a modified image of the surgical device that includes information related to one or more operating parameters.

Disclosed is an instrument assembly usable in a procedure. The instrument includes a connection for a working portion and to a tool handle. The assembly includes a method and system for interconnection and/or identification of the working portion and the handle. The instrument may also include various trackable features to allow for a navigated procedure.
