A training simulator for intraoperative neuromonitoring (IONM) systems includes channels where at least one of the channels is identified as an active stimulation channel and a subset of the rest of the channels is identified as reference or pick up sites. Channels of the subset having signal data that exceed a predefined threshold are retained for further processing, while channels with signal data that do not exceed the threshold are eliminated from further reporting. Response data for the remaining channels are generated in advance of a future time when the response would occur. The generated data is time stamped and stored for display at a time window when requested by the system.

A system and method of training how to use a medical device using an instrument such as a mock ultrasound probe or syringe to be tracked in 3D space with six degrees of freedom using an internal optical camera, a light source (e.g. infrared LEDs), and a display of markers arranged on a surface. By extracting corner information for each marker, a 3D transformation can be established, allowing the system to know the instrument's position and orientation in 3D space relative to that marker. Each marker also encodes a numerical value corresponding to its predetermined position and orientation on the surface, allowing the instrument to determine its own position and orientation relative to the surface. Thus, as long as the instrument is able to see at least one marker on an optical surface, the system will know its full 3D position and orientation relative to the whole optical surface.

Ultrasound (US) simulation systems and methods are provided, which utilize computer tomography (CT) data to generate US simulation images, offline or online. Systems and methods repeatedly derive and display consecutive US simulation images that correspond to consecutively-derived corresponding US slices (according to the changing locations and orientations of a dummy US transducer mimicking the US transducer with respect to a physical patient model)—that define geometrically US simulation regions. The US simulation images are at least partly derived from CT data using a CT to US conversion model. Acoustic parameters (e.g., tissue density, acoustic attenuation and impedance) are calculated and integrated per pixel, along beams in the US slice, to form the US image. Additional modelling may be used to calculate reflection and scattering and their effects on the image pixels, and enhancements such as animation and flow data may be added.

Aspects of the present disclosure relate to systems, devices and methods for performing a surgical step or surgical procedure with visual guidance using an optical head mounted display. Aspects of the present disclosure relate to systems, devices and methods for displaying, placing, fitting, sizing, selecting, aligning, moving a virtual implant on a physical anatomic structure of a patient and, optionally, modifying or changing the displaying, placing, fitting, sizing, selecting, aligning, moving, for example based on kinematic information.

A method of managing suture deployment onto a target organ tissue involves applying a label to a first portion of a first suture extending externally from a target organ, the first suture having a second portion deployed onto the target organ tissue within the target organ. The method further involves attaching a suture tab to the first portion or another portion of the first suture extending externally from the target organ, and applying tension to the first suture, wherein applying tension to the first suture comprises coupling the first suture to a tension guide and determining whether the tension is within a target range.

The present disclosure relates generally to the field of energy transfer mapping, including fixtures with two-dimensional and three-dimensional sensor arrays. In particular, the present disclosure relates to devices and methods for mapping of energy transfer from and/or to an instrument inserted within and/or into body tissue, including the depths and patterns of penetration and/or amounts of energy transfer to and/or from an instrument delivered within biological tissue or materials that mimic biological tissue, including within fixtures with three-dimensional temperature sensor arrays configured to simulate anatomical geometries such as the gastrointestinal (GI) or respiratory tract.

Instruments, guides, systems and related methods for total ankle prostheses are disclosed. The instruments, guides, systems and related methods facilitate preparation of a tibia and/or talus of a patient for implantation of a total ankle prosthesis therein. The instruments, guides, systems and related methods also facilitate selection of a particular size of a tibial component, a talus component and/or a tibial insert of the total ankle prosthesis that suits the patient. The instruments, guides, systems and related methods include a tibial trial component, a talar trial component and tibial insert trial component that replicate one or more aspects of the tibial component, the talus component and the tibial insert, respectively, of the total ankle prosthesis. The talar trial component includes an articulation surface that articulates with the tibial insert trial component, and slots that facilitate chamfered resection of the patient's talus for the implantation of the talus component thereon.

Systems and methods are provided for improving registration of AR (augmented reality) units at a surgery scene. Systems comprise augmented reality (AR) unit(s) comprising and/or in communication with head mounted display(s) (HMDs) used by a user, and physical device(s) made of sterilizable biocompatible material and configured as a registration template. The AR unit and/or segmentation software associated therewith may be configured to align a device representation of the physical device onto an imaging model of a patient, and the AR unit and/or the HMD may be configured to register, on the HMD, the device representation with the aligned imaging model onto the physical device, which is positioned with respect to the patient and is viewed through the HMD—to display the imaging model or parts thereof in a corresponding spatial relation to the patient. Registration using the physical device simplifies the coordination among real and virtual devices.

System and methods for simulating a surgical procedure are provided. The system includes a non-transitory computer-readable medium including instructions, which when executed by one or more processors, are configured to execute a surgical planning program. The surgical planning program is configured to track a tool relative to a model of an anatomy during a preoperative surgical simulation, generate a planning parameter based on the tracking of the tool relative to the model of the anatomy during the preoperative surgical simulation, and store the generated planning parameter. The system also includes a surgical system configured to load the generated planning parameter from the surgical planning program, and facilitate intraoperative surgery based on the generated parameter.
