The system also includes an instrument assembly that is used for performing spinal surgery where the instrument assembly includes a mounting platform and a jig.

Disclosed are systems, methods, and techniques for registering a HMD coordinate system of a head-mounted display (HMD) and a localizer coordinate system of a surgical navigation localizer. A camera of the HMD captures at least one image of a registration device having a registration coordinate system and a plurality of registration markers. The registration markers are analyzed in the at least one image to determine a pose of the HMD coordinate system relative to the registration coordinate system. One or more position sensors comprised in the localizer detect a plurality of tracking markers comprised in the registration device to determine a pose of the registration coordinate system relative to the localizer coordinate system. The HMD coordinate system and the localizer coordinate system are registered using the registration device, wherein positions of the registration markers are known with respect to positions of the tracking markers in the registration coordinate system.

Systems and methods are disclosed for use in electronic guidance systems for surgical navigation. A sensor is provided with an optical sensor, to provide optical information, and a measuring sensor, to provide measurements for determining a direction of gravity. The sensor communicates optical information and measurements to an inter-operative computing unit. In an embodiment, the inter-operative computing unit receives first optical information for a registration device and a patient anatomy and a measurement to determine a direction of gravity to perform a registration step. The inter-operative computing unit receives second optical information for the patient anatomy and an object and determines and presents measurements relative to the anatomy. The measurements relative to the anatomy are determined from the second optical information, and in relation to the registration of the anatomy of the patient.

An apparatus includes a cylindraceous sleeve body, a navigation sensor, and an interface feature. The cylindraceous sleeve body includes an open proximal end, an open distal end, and a lumen extending from the open proximal end to the open distal end. The lumen is sized and configured to receive a shaft of a medical instrument. The navigation sensor is positioned at the open distal end of the cylindraceous sleeve body. The interface feature is configured to couple the navigation sensor with an image guidance system. The navigation sensor is configured to cooperate with an image guidance system to provide feedback indicating a position of the navigation sensor in three-dimensional space.

A system for controlling ablation treatment and visualization is disclosed where the system comprises a tissue ablation instrument having one or more deployable stylets and a first electromagnetic sensor and an ultrasound imaging instrument which may be configured to generate an ultrasound imaging plane and further having a second electromagnetic sensor. An electromagnetic field generator may also be included which is configured for placement in proximity to a patient body and which is further configured to generate an output indicative of a position the first and second electromagnetic sensors relative to one another. Also included is a console in communication with the ablation instrument, ultrasound imaging instrument, and electromagnetic field generator, wherein the console is configured to generate a representative image of the tissue ablation instrument oriented relative to the ultrasound imaging plane and an ablation border or cage based upon a deployment position of the one or more stylets.

Presented herein are methods, systems, devices, and computer-readable media for image management in image-guided medical procedures. Some embodiments herein allow a physician to use multiple instruments for a surgery and simultaneously provide image-guidance data for those instruments. Various embodiments disclosed herein provide information to physicians about procedures they are performing, the devices (such as ablation needles, ultrasound transducers or probes, scalpels, cauterizers, etc.) they are using during the procedure, the relative emplacements or poses of these devices, prediction information for those devices, and other information. Some embodiments provide useful information about 3D data sets and allow the operator to control the presentation of regions of interest. Additionally, some embodiments provide for quick calibration of surgical instruments or attachments for surgical instruments.

Disclosed is a method to remove distortion from a navigation system. The navigation system may be used to perform a procedure on a subject. The procedure may be any appropriate procedure. The navigation system may be used to account for the distortive effects of various conductive objects positioned near the subject on which the procedure is performed.

A surgical system for operating on a bone of a patient is described. The surgical system includes a reference device including one or more radiopaque markers, a first sensor configured to generate a first signal pertaining to orientation data of the reference device relative to a first coordinate system, a surgical instrument for coupling to an end effector, a second sensor configured to generate a second signal pertaining to orientation data of at least one of the end effector and the surgical instrument relative to a second coordinate system, and a navigation system. The navigation system is configured to determine an orientation of at least one of the end effector and the surgical instrument and superimpose a virtual representation of at least one of the end effector and the surgical instrument over the image based on the determined orientation and user input.

A method for creating a patient-specific surgical plan includes receiving one or more pre-operative images of a patient having one or more infirmities affecting one or more anatomical joints. three-dimensional anatomical model of the one or more anatomical joints is created based on the one or more pre-operative images. One or more transfer functions and the three-dimensional anatomical model are used to identify a patient-specific implantation geometry that corrects the one or more infirmities. The transfer functions model performance of the one or more anatomical joints as a function of anatomical geometry and anatomical implantation features. surgical plan comprising the patient-specific implantation geometry may then be displayed.

A system for performing a surgical procedure includes a controller including a memory and a processor, the memory storing instructions, which when executed by the processor cause the processor to receive an image captured by a camera, generate a segmented image by applying a first threshold value to the image captured by the camera, identify a lumen within the segmented image, determine a centroid of the lumen within the segmented image, and align a portion of a surgical device operably coupled to the controller with the centroid of the lumen.
