A system for manipulating a guide catheter within a patient's nasal passages or sinus cavities includes a guide catheter formed from an elongate flexible member having a lumen passing there through. A wire guide is slidably disposed within the lumen of the guide catheter. The system further includes a steering member fixedly secured to a proximal end of the wire guide and a proximal hub secured to a proximal end of the guide catheter. The system further includes a recessed handle having a first recess for fixedly receiving the proximal hub of the guide catheter and a second recess for receiving the steering member, the second recess being dimensioned to permit axial and rotational movement of the steering member while disposed in the second recess.

Surgical systems, computer-implemented methods, and software programs for producing a patient-specific virtual boundary configured to constrain movement and/or operation of a surgical tool in response to the surgical tool interacting with the patient-specific virtual boundary. The implementations include obtaining a generic virtual boundary including a generic surface with a generic edge, and positioning the generic virtual boundary relative to a virtual anatomical model such that the generic surface intersects the virtual anatomical model. The implementations include computing an intersection of the generic surface and the virtual anatomical model to define a cross-sectional contour of the virtual anatomical model, and morphing the generic edge to the cross-sectional contour to produce a customized surface with a patient-specific edge. The implementations include generating a customized face extending from, and along, the patient-specific edge, and producing the patient-specific virtual boundary by merging the customized surface and the customized face.

A system, including a needle guide defining a path of travel of a needle inserted through the guide, and a tissue manipulator configured to approximate tissue and said needle guide and to position at least a portion of the tissue in the path of travel of the needle, and wherein the tissue manipulator and the needle guide are alignable such that the path of travel crosses a same surface of the tissue a plurality of times.

Surgical sealing ports for use with surgical instruments for access of a natural body orifice are provided. In one exemplary embodiment, a surgical sealing port includes a seal housing and at least one retention element. The seal housing is configured to be at least partially disposed within a natural body orifice and defining a plurality of ports. The plurality of ports includes at least one first port configured to control the ingress and egress of fluid between an interior volume of the natural body orifice and an ambient environment, and at least one second port that is configured to form a seal around an instrument inserted therethrough. The at least one retention element is arranged on an exterior surface of the housing and configured to affix the housing to the natural body orifice. Methods for using the same are also provided.

An optical tracking system is provided. The optical tracking system comprises an autoclavable fiducial marker assembly including an opaque housing, a light source, a window panel configured to refract light rays from the light source therethrough, and a metallized coating forming a hermetic seal at an interface of the window panel and the opaque housing. The fiducial marker assembly is configured to shield a peripheral edge of the window panel from the light rays. The system further comprises a tracking device comprising at least two optical sensors configured to detect a position of a light ray emitted by the light source. The system further comprises a processor configured to receive the position of the light rays from the optical sensors, shift the position of each light ray based on a calculated refraction deviation, and triangulate the location of the light source based on the shifted position of each light ray.

Systems, devices and methods are provided for facilitating surgical guidance using a surface detection device. In some example embodiments, a trackable surface detection device is disclosed that includes, in a spatially-fixed relationship, a surface detection subsystem, one or more reference markers that are detectable by a tracking system, and an integrated reference feature that is detectable by the surface detection subsystem for calibration thereof. The trackable surface detection device, which may be handheld, facilitates the determination of a calibration transform that relates a frame of reference of the surface detection subsystem to a frame of reference of the tracking system, which in turn may be employed, in combination with a transform obtained by performing surface-to-surface registration of intraoperatively detected surface data and pre-operative image data pertaining to a subject, when generating an intraoperative display, in a common frame of reference, of the pre-operative image data and a tracked surgical tool.

A surgical instrument comprising a first jaw and a second jaw is disclosed. At least one of the first and second jaws comprises a proximal portion and a distal tip rotatable relative to the proximal portion.

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.

This invention is a system and method for utilizing artificial intelligence to operate a surgical robot (e.g., to perform a laminectomy), including a surgical robot, an artificial intelligence guidance system, an image recognition system, an image recognition database, and a database of past procedures with sensor data, electronic medical records, and imaging data. The image recognition system may identify the tissue type present in the patient and if it is the desired tissue type, the AI guidance system may remove a layer of that tissue with the end effector on the surgical robot, and have the surgeon define the tissue type if the image recognition system identified the tissue as anything other than the desired tissue type.

Presented are methods and systems for determining, monitoring, and displaying the relative positioning of two rigid bodies such as during a surgery. In particular, the present disclosure relates to methods and systems for positioning a prosthesis relative to a bone during a surgery as well as to systems and methods for verifying resulting relative positioning of adjacent bones.
