Systems, methods, software and techniques for generating a milling path for a tool of a surgical system are provided. The milling path is designed to remove a resection volume associated with an anatomical volume. A reference guide is defined with respect to the resection volume. Sections are defined along the reference guide in succession. Each section intersects the reference guide at a different intersection point and is at a specified orientation relative to the reference guide at the intersection point. Each section further intersects the resection volume. A section path is generated to be bounded within each section and defined relative to the resection volume. A plurality of transition segments are generated and each transition segment connects section paths of successive sections along the reference guide.

The present disclosure relates to a method for manufacturing nose implant, including obtaining a 3-dimensional image of a nasal bone and a 3-dimensional image of a nasal cavity; modeling a nasal cartilage by applying information of anatomy between the nasal bone, nasal cavity, and nasal cartilage, to the 3-dimensional image of the nasal bone and the 3-dimensional image of the nasal cavity; and modeling an inner shape of where the implant may be seated, from the 3-dimensional image of the nasal bone and the modelled nasal cartilage.

A surgical system includes a robotic device, a surgical tool mounted on the robotic device, and a processing circuit. The processing circuit is configured to receive image data of an anatomy, generate a virtual bone model based on the image data, identify a soft tissue attachment point on the virtual bone model, plan placement of an implant based on the soft tissue attachment point, generate a control object based on the placement of the implant, and control the robotic device to confine the surgical tool within the control object.

Systems and methods for visualizing navigation of a medical device with respect to a target using a live fluoroscopic view. The methods include displaying, in a screen, a three-dimensional (3D) view of a 3D model of a target from the perspective of a medical device tip. The methods also include displaying, in the screen, a live two-dimensional (2D) fluoroscopic view showing a medical device, and displaying a target mark, which corresponds to the 3D model of the target, overlaid on the live 2D fluoroscopic view. The methods may include determining whether the medical device tip is aligned with the target, displaying the target mark in a first color if the medical device tip is aligned with the target, and displaying the target mark in second color different from the first color if the medical device tip is not aligned with the target.

Examples of systems and methods described herein may utilize augmented reality devices and pointers in generating intra-operative plans and providing guidance for knee surgery. A pointer may indicate one or more anatomical points. An augmented reality device may detect positions of knee anatomical features based on a position of the pointer and positions of fiducials associated with a marker affixed to body part proximate to a knee, such as a femur or a tibia. The augmented reality device may generate a planned resection plane based on the positions of the knee anatomical features, and determine an actual resection plane based on a view of a resection guide having a marker inserted in the guide. The augmented reality device may provide guidance to position the guide to align the actual resection plane with the planned resection plane.

Methods, systems and devices for pre-operatively planned shoulder surgery guides and implants. Pre-operative planning methods for designing glenoid placement guides and depth-control pins based on considerations of multiple factors affecting the outcome of shoulder surgery. Methods of using surgery guides and implants, including glenoid placement guides and depth-control pins, in patients undergoing shoulder surgery.

A spinal disorder diagnosis and treatment planning system is provided. The diagnosis and treatment planning system includes a mixed reality holographic display including at least one processor, at least one camera, at least one sensor, and being configured to acquire data points corresponding to a surface of a body adjacent to vertebral tissue. A computer database is configured to transmit imaging of the body including the vertebral tissue to the mixed reality holographic display. The mixed reality holographic display is configured to display a first holographic image of the vertebral tissue superimposed with a body image including the surface. Methods are also disclosed.

An example physical tracking tool includes a main body defining a channel configured to receive a tool, the channel having a longitudinal axis; and one or more physical tracking features attached to the main body, each physical tracking feature comprising a plurality of planar faces, each planar face of the plurality of planar faces including different a graphical pattern of a plurality of graphical patterns.

Logic may determine how to reduce bone segments. Logic may communicate one or more images to display with at least two bone segments. Logic may identify a first reduction point and a third point on a first bone segment and identify a second reduction point and a fourth point on the second bone segment. Logic may identify a fifth point on the first bone segment and a sixth point on the second bone segment. Logic may also divide the one or more images along a line or plane between the bone segments, bring the second reduction point and the associated image segment to the first reduction point, align the line or plane of the second bone segment with a line or plane of the first bone segment. Furthermore, logic may adjust alignment and record the movement of the image segments or compare original and final positions, to determine deformity parameters.

A spinal correction rod implant manufacturing process includes: estimating a targeted spinal correction rod implant shape based on a patient specific spine shape correction and including spine 3D modeling, one or more simulation loops each including: first simulating an intermediate spinal correction rod implant shape from modeling mechanical interaction between the patient specific spine and: either, for the first simulation, the implant shape, or, for subsequent simulation, if any, an overbent implant shape resulting from the previous simulation loop, a second simulation of an implant shape overbending applied to the targeted spinal correction rod implant shape producing an overbent spinal correction rod implant shape representing a difference between: either, for the first loop, the targeted spinal correction rod implant shape, or, for subsequent loop, if any, the overbent spinal correction rod implant shape resulting from the previous simulation loop, and the intermediate spinal correction rod implant shape.
