MEDICAL DEVICE, METHOD AND SYSTEM THEREOF
Embodiments of the invention are directed towards a medical device, method and system thereof for the placement or passage of patches, sutures, anchors, tags, tissue sensors and more particularly to a medical device for repairing female pelvic organ or tissue prolapsed region. The device may be used for the placement of stereotactic markers into tissue near joints or tumors for guidance during orthopedic or neurosurgical procedures.
Method for measuring a subject's eye movement and scleral contact lens
Method and contact lens (3) for measuring a subject's three dimensional eye movement including torsional movement. A video camera (1) is provided for recording an image of the subject's eye (2). The contact lens (3) is provided for placement over the subject's eye (2). The contact lens (3) comprises one or more markers (3a,3b) that are detectable by the video camera (1) and are positioned at a lateral offset (D) with respect to a central part (3p) of the contact lens (3). The one or more markers (3a,3b) are configured for detecting torsional rotation (R) of the subject's eye (2) around a line of sight axis (C) of the subject's eye (2) by using the video camera (1) to track a position of the one or more markers (3a,3b).
Mixed-reality surgical system with physical markers for registration of virtual models
An example method includes obtaining, a virtual model of a portion of an anatomy of a patient obtained from a virtual surgical plan for an orthopedic joint repair surgical procedure to attach a prosthetic to the anatomy; identifying, based on data obtained by one or more sensors, positions of one or more physical markers positioned relative to the anatomy of the patient; and registering, based on the identified positions, the virtual model of the portion of the anatomy with a corresponding observed portion of the anatomy.
Method and system for hand tracking in a robotic system
A method and system for hand tracking in a robotic system includes a hand tracking system and a controller coupled to the hand tracking system. The controller is configured to receive, from the hand tracking system, a plurality of locations of a hand; determine if the hand is in a first hand pose based on the plurality of locations; in response to determining that the hand is in the first hand pose, and switch the robotic system to a hand trajectory detection mode. While in the hand trajectory detection mode, the control unit is configured to detect, based on hand tracking information from the hand tracking system, that the hand has performed a first hand trajectory of a plurality of known hand trajectories; and in response to detecting the first hand trajectory, change a mode of operation of the robotic system.
SURGICAL PERFORATION BETWEEN THE AORTA AND LEFT ATRIUM
Apparatuses and methods are disclosed for the perforation of a communication between the aorta and left atrium. The method includes introducing the apparatus, positioning the apparatus at a location along the aorta, and energizing the apparatus to create a perforation. For example, one method may include: introducing a flexible wire into the left atrium, advancing a dilator along the flexible wire to position the flexible wire adjacent a selected location along the aorta and energizing the flexible wire to create a perforation from the left atrium into the aorta.
METHODS FOR OPTICAL TRACKING AND SURFACE ACQUISITION IN SURGICAL ENVIRONMENTS AND DEVICES THEREOF
A computer assisted system is disclosed that includes an optical tracking system and one or more computing devices. The optical tracking system includes an RGB sensor and is configured to capture color images of an environment in the visible light spectrum and tracking images of fiducials in the environment in a near-infrared spectrum. The computer assisted system is configured to generate a color image of the environment using the color images, identify fiducial locations using the tracking images, generate depth maps from the color images, reconstruct three-dimensional surfaces of structures based on the depth maps, and output a display comprising the reconstructed three-dimensional surface and one or more surgical objects that are associated with the tracked fiducials. The computer assisted system can further include a monitor or a head-mounted display (HMD) configured to present augmented reality (AR) images during a procedure.
Techniques for patient-specific milling path generation
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.
NEEDLE LOCALIZATION REFLECTORS, SYSTEMS, AND METHODS
Apparatus, systems, and methods are provided for localization of a needle within a patient's body using markers. In an exemplary embodiment, a probe includes a distal end for placement against a surface of the region and one or more antennas for transmitting electromagnetic signals into and receiving reflected signals from the region. A processor processes the modulated reflected signals at one or more of the surface locations to determine marker locations along the needle and generate a three-dimensional model of the body region and needle.
DETERMINING AN AVOIDANCE REGION FOR A REFERENCE DEVICE
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.
SYSTEMS AND METHODS FOR C-SHAPED SPINES FORMING A SPHERICAL BASKET FOR IMPROVED TISSUE CONTACT AND CURRENT DELIVERY
The disclosed technology includes a medical probe comprising a tubular shaft extending along a longitudinal axis and including a proximal end and a distal end. The medical probe further comprises an expandable basket assembly proximate the distal end of the tubular shaft. The basket assembly comprises a plurality of C-shaped spines and one or more electrodes coupled to each of the spines, each electrode defining a lumen through the electrode so that a spine extends through the lumen of each of the one or more electrodes. The spines converge at a central spine intersection at a distal end of the basket assembly. Each spine comprises a respective end connected to the distal end of the tubular shaft.
