A method for creating a patient-specific surgical plan includes receiving one or more pre-operative images of a patient having one or more infirmities affecting one or more anatomical joints. three-dimensional anatomical model of the one or more anatomical joints is created based on the one or more pre-operative images. One or more transfer functions and the three-dimensional anatomical model are used to identify a patient-specific implantation geometry that corrects the one or more infirmities. The transfer functions model performance of the one or more anatomical joints as a function of anatomical geometry and anatomical implantation features. surgical plan comprising the patient-specific implantation geometry may then be displayed.

The present disclosure relates to a method of manufacture of a dental implant for a molar, including acquiring, structural data corresponding to bones of the facial skeleton, the bones of the facial skeleton being proximate the molar, selecting, as a dental implant fixation surface, a surface of the bones based upon a determined thickness of the bones, generating, based on the selected dental implant fixation surface, a contoured surface of the dental implant, and fabricating, based upon an instruction transmitted by processing circuitry, a bone plate extending from a buccal end of a cylindrical plate of the dental implant, the cylindrical plate having support lattices extending therefrom, at least one support lattice of the support lattices being arranged on a lingual end of the cylindrical plate, the cylindrical plate having an opening in a central region thereof, the opening being configured to receive a dental post.

A number of improvements are provided relating to computer aided surgery. The improvement relates to both the methods used during computer aided surgery and the devices used during such procedures. Some of the improvement relate to controlling the selection of which data to display during a procedure and/or how the data is displayed to aid the surgeon. Other improvements relate to the structure of the tools used during a procedure and how the tools can be controlled automatically to improve the efficiency of the procedure. Still other improvements relate to methods of providing feedback during a procedure to improve either the efficiency or quality, or both, for a procedure.

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.

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.

A system is suggested comprising an optical sensing means and a processing unit. The optical sensing means may include an optical guide with a distal end, wherein the optical guide may be configured to be arranged in a device to be inserted into tissue in a region of interest. The processing unit may be configured to receive information of a region of interest including different tissue types as well as of a path through the tissues, to determine a sequence of tissue types along the path, to determine a tissue type at the distal end of the optical guide based on information received from the optical sensing means, to compare the determined tissue type with the tissue types on the path, to determine possible positions of the distal end of the optical guide on the path based on the comparison of tissue types, and to generate a signal indicative for the possible positions.

A surgical system includes an arm extending from the base and having a distal end configured to be coupled to a tool, a first marker coupled in fixed relation to the base, and a tracking system. The tracking system is configured to collect first data indicative of a position of the first marker and collect second data indicative of a position an anatomical feature of a patient. The surgical system also includes a processor configured to calculate a position of the tool relative to the anatomical feature based on the first data and the second data.

A system for assessing laxity of a joint of a patient is disclosed. The system comprises a tensioner tool having a substantially rigid portion that may be inserted within the joint to apply a force against a bone surface thereof. The system further comprises a tensioner sock having a flexible body with an opening to receive the tensioner tool and a sensor array disposed on the flexible body. Each sensor of the sensor array is configured to contact the bone surface and detect a pressure when the force is applied against the bone surface. The system further comprises a processor configured to receive the detected pressure from each sensor and calculate the force applied to the bone surface based on the detected pressures.

A computer-implemented method plans a position of a tracking reference device for referencing a position in a medical environment. The method includes a determination of avoidance regions in which a tracking reference device should not be placed so as to safeguard proper tracking of the tracking reference device and/or an instrument tracking reference device which is attached to a medical instrument. The avoidance region is a region lying, from the point of view of a tracking device for tracking the tracking reference device, in the shadow of an envelope surrounding at least one medical instrument. Additionally or alternatively, an avoidance region may lie in between the position of the tracking device and the envelope to avoid a shadowing, by the tracking reference device, of an instrument tracking reference device attached to the medical instrument. Information describing the position of the at least one avoidance region is displayed to a user, and also information about the position of a region which is suitable for placement of the tracking reference device can be displayed to the user.
