A surgical navigation system for providing computer-aided surgery. The surgical navigation system includes a handheld surgical tool with computer-aided navigation, a graphical user interface module, and optionally an imaging device. The handheld surgical tool includes a handle that may comprise at least one sensor for detecting orientation of the. A computing device and at least one display device are associated with the handheld surgical tool and configured to display a target trajectory of the handheld surgical tool for the surgical 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.

An implanted article physical referencing apparatus comprises a guide body, a first guide shaft and a second guide shaft. The guide body includes a plurality of guide shaft receptacles therein. A longitudinal axis of each of the guide shaft receptacles extends substantially parallel to a longitudinal reference axis of the guide body. The first and second guide shafts each have a proximate end portion and a distal end portion. The proximate end portion of the first guide shaft includes an exterior surface adapted for being engaged with a corresponding interior surface of a selected one of the guide shaft receptacles to constrain unrestricted relative movement between the first guide shaft and the guide body. The proximate end portion of the second guide shaft is attached to the guide body. A longitudinal axis of the second guide shaft extends substantially parallel to the longitudinal reference axis of the guide body.

A method is provided for determining the shape of a surgical linking device that is to be attached to a bony body structure such as the spinal column based on digitized locations of a plurality of attachment elements engaged to the bony structure. The method is implemented by a computer system through a GUI to generate an initial bend curve to mate with the plurality of attachment elements. The initial bend curve may be simplified based on user input to the GUI to reduce the number of bends necessary to produce a well-fitting linking device and may be altered to help obtain the goals of surgery.

The present disclosure presents a trajectory array guide system for defining a trajectory to a target location in the brain of a subject and for guiding an elongated tool along the trajectory. The trajectory array guide system can comprise: a base, an array guide, an imaging unit, and an elongated handle configured for connection with a stereotaxic navigation system. The present disclosure presents a method of using a trajectory array guide system for defining a trajectory to a target location in the brain of a subject and for guiding an elongated tool along the trajectory.

A surgical navigation system comprising a spatial positioning marker component (600) on a surgical instrument, a tracer on a bone structure, a binocular camera (501), and a computer (502). The tracer is provided with a navigation tracer surface (200). The spatial positioning marker component (600) comprises a navigation surface (601). The binocular camera (501) is connected to the computer (502), and transmits acquired information of the tracer and the spatial positioning marker component (600) to the computer (502). The computer (502) and a computer readable storage medium each separately store a computer program for performing a surgical navigation method. The method comprises; generating three-dimensional models of a bone and the surgical instrument, and obtaining tracer registration information and calibration information of the spatial positioning marker component (600); receiving real-time information of the tracer and the spatial positioning marker component (600) acquired by the binocular camera (501); and calculating spatial position information of the bone and the surgical instrument, and fusing, in real-time, the information with the three-dimensional models to obtain a dynamic image of a real-time positional relationship therebetween. The invention eliminates intraoperative registration used for surgical navigation, simplifies surgical processes, and improves surgical precision.

Provided herein are platforms and methods for mapping a three-dimensional (3D) dental anatomy of a subject.

Various embodiments of an apparatus, methods, systems and computer program products described herein are directed to Field Visualization Engine. The Field Visualization Engine tracks one or more collimator poses relative to one or more Augmented Reality (AR) headset device poses. Each respective collimator pose and each respective headset device pose corresponds to a three-dimensional (3D) unified coordinate space (“3D space”). The Field Visualization Engine generates an AR representation of a beam emanating from the collimator based at least on a current collimator pose and a current headset device pose. The Field Visualization Engine further generates an AR visualization of emanation of the beam throughout an AR display of medical data.

Systems and methods for generating multiple registrations is provided. An image depicting a portion of a patient's anatomy and a tracking device affixed to an accurate robot may be received. A first registration of a patient coordinate space to a robotic coordinate space may be generated based on the image. A second registration of the patient coordinate space to a navigation coordinate space based at least in part on a position of second markers on the tracking device detected by a navigation system may be generated. The first registration and the second registration may be independent of each other.

A system and method is provided for planning a surgical procedure. The system includes a model of an anatomical region including simulated bone, a tracked tool, a tracking system, a display device, and a computer system configured to receive information from the tracking system, generate and display the model and the tracked tool, and store the tracking system information in a computer readable memory that is portable to a surgical navigation system. The method includes acquiring volumetric data of a patient anatomical region, extracting, providing and registering a three-dimensional model with the volumetric data, using a tracked tool to perform a simulated surgical procedure including removing and replacing a bone section on the model, viewing the model and the tracked tool on a display device, recording the procedure with a tracking system, storing the procedure in a computer readable memory, and porting the procedure into a surgical navigation system.
