    摘要: An ablation instrument includes a shaft that extends from a grip portion. A curved portion of the shaft is shaped to allow insertion into the head of a patient, and to position an ablation tip that extends from a distal tip of the shaft proximate to an ablation target, such as the posterior nasal nerve. When activated the ablation tip projects radiofrequency energy to ablate nearby tissue. An ablation assistance features of an image guided surgery navigation system is configured to segment and identify ablation targets within a set of pre-operative images. When a position tracked ablation instrument is configured for use, the system begins to monitor the proximity of the ablation tip to the ablation targets. When the tip is within an effective distance of the target for ablation, the system provides an alert and activates the instrument so that RF energy may be projected.

    摘要: Tools used within a surgical area may be equipped with sensors that allow them to be tracked within the magnetic field of an image guided surgery (IGS) system. The IGS system may be configured to detect various movement patterns of the tools, which may be mapped to and associated with corresponding actions or inputs to the IGS system. In one example, a registration probe may be moved along the x-axis and y-axis, with detected movements identified and received by the IGS system as movements of a mouse cursor on a display of the IGS system. In another example, the registration probe may be moved in a circular pattern, or quickly moved along any of the x-axis, y-axis, or z-axis, with each being configured to cause the IGS system to zoom a display, change a view, record video, or other actions.

    摘要: A visualization system may be implemented with an image guided surgery navigation system for use during ENT procedures. Correlated datasets such as surgical paths and pre-operative image slices may be correlated with the coordinate system of the navigation system for reference during a procedure. A surgeon may wear a head mounted display (“HMD”) having a transparent screen through which the patient anatomy may be viewed. The orientation and distance of the head mounted display relative to the patient anatomy may be determined using magnetic position tracking, image analysis of images captured by a camera of the HMD, or both. Correlated datasets may then be transformed based on the relative distance and orientation and may be displayed via the transparent screen to overlay directly viewed patient anatomy. Some implementations may include optical fiducials integrated with a patient tracking assembly to aid in tracking the patient and determining perspective of the HMD.
