Methods and systems for preparing a bone for a cementless joint implant are described. A first bone removal operation is performed using a burring device that has a first plurality of settings. The settings for the burring device are adjusted to a second plurality of settings, and a second bone removal operation is performed using the burring device. The adjustment to the settings may allow a surgeon to perform bulk bone removal in the first instance and fine bone removal in the second instance. The process of adjusting and performing subsequent bone removal operations may be performed any number of times during the bone preparation process. The adjustments to the settings may be received automatically from a computer-assisted surgical system, manually entered by a medical professional, or a combination of the two.

Systems and methods for performing an osteotomy with robotic assistance are disclosed. The disclosed systems and methods includes receiving a three-dimensional model of a patient bone, receiving a surgical plan, determining, based on the three-dimensional model and the surgical plan, one or more corrective cuts to be made to the patient bone, and performing, using a tracked end effector interfaced to a robotic arm, the one or more corrective cuts. A surgeon may utilize software, tracking, robotics, and the like to plan and execute bone resection in complex and/or intricate shapes not previously possible.

A method for using an assembled three-dimensional image to construct a three-dimensional model for determining a path through a lumen network to a target. The three-dimensional model is automatically registered to an actual location of a probe by tracking and recording the positions of the probe and continually adjusting the registration between the model and a display of the probe position. The registration algorithm becomes dynamic (elastic) as the probe approaches smaller lumens in the periphery of the network where movement has a bigger impact on the registration between the model and the probe display.

Methods and systems for providing treatment planning information for a neurology procedure, including neurosurgical procedures. A database containing historical data about historical procedures is accessed. Historical data relevant to a neurology procedure is determined, based on a determination of similarity to a set of data characterizing the neurology procedure. Historical instances of procedure parameters relevant to the neurology procedure are determined and displayed.

An aspect of the disclosure relates to a method for generating a reference information item of an eye, wherein at least one characterization information item that characterizes a rhexis size and/or a rhexis position of a potential actual rhexis on an anterior capsular bag wall of the eye is input into an input unit of an ophthalmic surgical apparatus and, depending on the characterization information item, a reference rhexis is determined as at least a constituent part of the reference information item of the eye by an evaluation unit of the ophthalmic surgical apparatus, wherein the determined reference rhexis is optically displayed by an optical display unit of the ophthalmic surgical apparatus. The disclosure further relates to an ophthalmic surgical apparatus.

A method for creating surgical simulation information by a computer includes creating a virtual body model corresponding to a body state of a patient for surgery, simulating a specific surgical process on the virtual body model to obtain virtual surgical data, dividing the virtual surgical data into minimum surgical operation units, each unit representing one specific operation, and creating cue sheet data composed of the minimum surgical operation units, wherein the cue sheet data represents the specific surgical process.

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.

A surgical planning system for use in surgical procedures to repair an anatomy of interest includes a preplanning system to generate a virtual surgical plan and a mixed reality system that includes a visualization device wearable by a user to view the virtual surgical plan projected in a real environment. The virtual surgical plan includes a 3D virtual model of the anatomy of interest. When wearing the visualization device, the user can align the 3D virtual model with the real anatomy of interest, thereby achieving a registration between details of the virtual surgical plan and the real anatomy of interest. The registration enables a surgeon to implement the virtual surgical plan on the real anatomy of interest without the use of tracking markers.

Systems and methods are provided to aid in planning at least a portion of a total knee arthroplasty procedure. The system and method automatically aligns the implant components and the bones according to a desired clinical alignment goal with minimum user input. The system and method further allows the user to adjust the position and orientation of the femur, tibia, or implant in a clinical direction regardless of a pre-adjusted position and orientation of the femur, tibia, or implant. The graphical user interface is provided that includes a three-dimensional (3-D) view window, a view options window, a patient information window, an implant family window, a workflow-specific tasks window, and a limb and knee alignment measures window.
