A surgical device includes an body extending from a proximal end to a distal end. The distal end of the body defines a notch sized and configured to receive a reamer. A coupling assembly is supported by the body and includes a reamer guide body disposed at the distal end of the body. The reamer guide body configured to move between a first position and a second position in which the reaming guide body extends at least partially across the notch. A locking assembly is supported by the body and is configured to releasably engage the coupling assembly to maintain the reamer guide body in the second position.

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

Computer-assisted surgery device and a method for operating the same which allows a more efficient positioning and application of an implant with respect to a bony structure, and in particular a shorter operation time and less intensity of x-ray exposure for a patient. A device for computer-assisted surgery includes a reference structure, a first arm, a second arm, a position determining unit and a motion controlling unit.

Surgical systems and methods are provided that utilize augmented reality navigation and visualization techniques for transferring aspects of a preoperative surgical plan to an actual surgical site. The surgical systems and methods may be utilized to achieve accurate alignment of a surgical positioning object, such as a guide pin for guiding surgical reaming procedures, between the preoperative surgical plan and the intraoperative anatomy associated with the actual surgical site. Augmented reality may be utilized to achieve visualization of both an entry point and a drilling trajectory of the surgical positioning object in a manner that avoids occluding the intraoperative anatomy during the procedure.

Systems, methods and devices for use in tracking are described, using optical modalities to detect spatial attributes or natural features of objects, such as, tools and patient anatomy. Spatial attributes or natural features may be known or may be detected by the tracking system. The system, methods and devices can further be used to verify a calibration of a tool either by a computing unit or by a user. Further, the disclosure relates to detection of spatial attributes, including depth information, of the anatomy for purposes of registration or to create a 3D surface profile of the anatomy.

A surgical instrument assembly may include a processor, a surgical instrument configured to operate on an anatomical structure, and a display coupled to the processor and attached to the surgical instrument. The processor can be configured to determine a position of the medical imaging device, from which the medical imaging device can generate an X-ray image that includes holes of an intramedullary nail shown as circles, for instance perfect circles. In an example, the processor identifies the intramedullary nail, so as to determine an intramedullary nail identity, and determines the position of the medical imaging device based on a portion of at least two locking holes of the intramedullary nail and based on the intramedullary nail identity.

A system and method provide for image-guided implant placement as a function of at least one intraoperative image during a surgical procedure. At least one computing device is configured by executing code stored in non-transitory processor readable media to process at least one preoperative image to assess axial rotation and/or sagittal pelvic inclination. Further, as a function of a plurality of identified anatomical landmarks in the at least one preoperative image, at least one of distances, angles, and areas is measured. Thereafter, as a function of calculations associated with the at least one of distances, angles, and areas, axial rotation associated with at least one image is measured. Thereafter, at least one value associated with placement of an implant during the surgical procedure is adjusted and information associated therewith is provided via a graphical user interface.

Surgical systems and methods for tracking physical objects near a target site during a surgical procedure are provided, the surgical system employs a navigation system and a surgical instrument; an instrument tracker is provided on the surgical instrument and a patient tracker is provided on the patient's target tissue; the system and method is configured to detect an error condition compromising accuracy of the navigation guidance and to track and monitor a tool-to-bone offset.

Systems and methods are disclosed in which changes in the position and/or orientation of an anatomical structure or of a surgical tool can be measured quantitatively during surgery. In some embodiments, the systems and methods disclosed herein can make use of inertial motion sensors to determine a position or orientation of an instrument or anatomy at different times and to calculate changes between different positions or orientations. In other embodiments, such sensors can be utilized in conjunction with imaging devices to correlate sensor position with anatomical landmarks, thereby permitting determination of absolute angular orientation of a landmark. Such systems and methods can facilitate real-time tracking of progress during a variety of procedures, including, e.g., spinal deformity correction, etc.

The inventive subject matter is directed to an artificial intelligence intra-operative surgical guidance system and method of use. The artificial intelligence intra-operative surgical guidance system is made of a computer executing one or more automated artificial intelligence models trained on data layer datasets collections to calculate surgical decision risks, and provide intra-operative surgical guidance; and a display configured to provide visual guidance to a user.
