Abstract: An external fixator system may be used for a procedure on a patient. The external fixator system may include a hexapod, which for example may include a plurality of components. Example components may include one or more rings and one or more struts. For example, the hexapod may include an upper ring, a lower ring, and a strut. The strut may be included in a plurality of struts, for example of various sizes. A system may include a computer-readable medium used to determine a subset of components. The computer-readable medium may be stored, for example in a memory and may include instruction stored thereon instructions. The instructions may be executed by a processor. When executed, the system may determine the subset of components. The system may determine the subset of components based on one or more of the constraints and/or the range of possible values for the constraint.

Abstract: A fixation apparatus may be attached to first and second anatomical structure segments. Images of the fixation apparatus and the attached anatomical structure segments may then be captured. In some examples, the images need not necessarily be orthogonal with respect to one another. Configuration information associated with the fixation apparatus may then be received. Additionally, first image information may be received, for example including indications of one or more locations, within the images, of at least part of one or more elements of the fixation apparatus. Additionally, second image information may be received, for example including indications of one or more locations, within the images, of at least part of the first and the second anatomical structure segments. Manipulations to the fixation apparatus for correction of the anatomical structure deformity may then be determined, and indications of the determined manipulations may then be provided to one or more users.

Abstract: First and second images are displayed of anatomical structure segments with an attached fixator. Indications may be received of first image hinge locations of a plurality of hinges of the fixator in the first image. Projected second image hinge locations may be determined based at least in part on the first image hinge locations. Hinge candidates may be detected in the second image having shapes associated with the plurality of hinges. The hinges candidates may be detected by computer software using automated software-based image analysis techniques. Adjusted second image hinge locations may then be calculated based at least in part on the projected second image hinge locations and candidate second image hinge locations. The adjusted second image hinge locations may be used to determine physical locations of the fixator and anatomical structure segments in three-dimensional space, which may be used to determine manipulations to the fixator for deformity correction.

Abstract: A plurality of three-dimensional fixator graphical representations may include graphical indications of a strut swap range. A plurality of replaced strut graphical representations may change from a first rendering state in a swap start fixator graphical representation to a second rendering state in a swap end fixator graphical representation. A plurality of replacement graphical representations may change from the second rendering state in the swap start fixator graphical representation to the first rendering state in the swap end fixator graphical representation. In some examples, the plurality of replaced strut graphical representations may gradually fade out from a swap start stage to a swap end stage, and the plurality of replacement strut graphical representations may gradually fade in from a swap start stage to a swap end stage. Additionally, a treatment plan including at least one interfamily strut swap may be generated for manipulating a fixator to correct a deformity.

Abstract: A guided frame matching technique may be employed in which a graphical projection of a fixator is used to guide and assist a user in identifying fixator elements within an image. Upon being overlaid on an image, the graphical projection of fixator may be manipulated to align with, and overlay, fixator elements displayed within the image. Additionally, a three-dimensional overview of an imaging scene of the fixator may be generated. The three-dimensional overview may include a three-dimensional graphical model that displays representations of images of the fixator attached to anatomical structure segments as well as representations of imaging sources, reference locations, fixator elements, and anatomical structure segments. When the images are not truly orthogonal, a modified second image representation may be displayed to represent a second image that is truly orthogonal to a first image.

Abstract: The invention relates to a holder device (1) for medical instruments, including endoscopes, or cannulas, such as those that are used within the framework of minimally invasive surgery or interventional radiology. Proceeding from a state of the art in which the treating physician knows holder devices (1) and guidance systems, an improved holder device (1) is proposed within the framework of the invention, which makes it possible, at any time, to uncouple the holder device (1) and, if applicable, the guidance system connected with the holder device (1), from the medical instruments or cannulas held with the holder device (1), without having to retract or remove the instruments or cannulas.
