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.

Devices, systems, and methods for visualizing a reference location of an electrophysiology device in an anatomical image are provided. According to one embodiment, an electrophysiological mapping and guidance system includes a processor circuit in communication with a catheter carrying a plurality of electrodes. The processor circuit controls the plurality of electrodes to obtain electrical measurements (e.g., voltage measurements) of an electrical field induced within an anatomical cavity.

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 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.

A surgical system comprises an articulated mechanical arm comprising arm segments connected serially by arm joints that flex and rotate, and first and second input-devices. The second input-device comprises a handle configurable to be oriented in any orientation in an x-y-z space, and the handle comprises segment members and joint members corresponding to the arm segments and arm joints of the arm. The arm joints can be actuatable by, and have the same degrees of freedom as, the handle joint member. A method of using the surgical system includes retroflecting the arm, transitioning control of the arm from the first input device to the second input device, and performing a surgical action, during which a displacement vector or a reorientation arc of the handle member through the x-y-z space is translated to a corresponding displacement vector or corresponding reorientation arc of the end effector in the same x-y-z space.

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.

Disclosed is a localizer system. The localizer system may be incorporated into a navigation system for tracking a tracking device. Generally, the localizer may include a transmitting coil array and a field shaping assembly.

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.

A method for adjusting the operation of a surgical instrument using machine learning in a surgical suite is disclosed. The method comprises the steps of gathering data during surgical procedures, wherein the surgical procedures include the use of a surgical instrument, analyzing the gathered data to determine an appropriate operational adjustment of the surgical instrument, and adjusting the operation of the surgical instrument to improve the operation of the surgical instrument.
