Systems and methods for visualizing navigation of a medical device with respect to a target using a live fluoroscopic view. The methods include displaying, in a screen, a three-dimensional (3D) view of a 3D model of a target from the perspective of a medical device tip. The methods also include displaying, in the screen, a live two-dimensional (2D) fluoroscopic view showing a medical device, and displaying a target mark, which corresponds to the 3D model of the target, overlaid on the live 2D fluoroscopic view. The methods may include determining whether the medical device tip is aligned with the target, displaying the target mark in a first color if the medical device tip is aligned with the target, and displaying the target mark in second color different from the first color if the medical device tip is not aligned with the target.

A medical arm control system circuitry configured to generate autonomous operation control information to autonomously operate a medical arm based on external input information; simulate an operation performed using the medical arm; and correct the autonomous operation control information in real time based on a result of the simulation of the operation of the medical arm.

An exemplary robotic system and control method is disclosed that employs magnetic-resonance imaging (MRI) guided visual-servo positioning of a medical robot system. In an example, an MR Elastography (MRE) actuator system is disclosed that employs the exemplary MRI-guided visual servoing to assess tissues based on its mechanical properties. The exemplary MRI-guided positioning is directly and solely used as a feedback sensor through its visual output to control multiple degrees of movement of the MRE actuators. The exemplary MRI-guided positioning may be employed in various diagnostics, minimally invasive surgery, or medical procedures for any number of a medical instrument and interventional procedures that can be conducted in an MRI environment or in proximity to an MRI scanner.

A system and method for selectively treating aberrant cells such as cancer cells through administration of a train of electrical pulses is described. The pulse length and delay between successive pulses is optimized to produce effects on intracellular membrane potentials. Therapies based on the system and method produce two treatment zones: an ablation zone surrounding the electrodes within which aberrant cells are non-selectively killed and a selective treatment zone surrounding the ablation zone within which target cells are selectively killed through effects on intracellular membrane potentials. As a result, infiltrating tumor cells within a tumor margin can be effectively treated while sparing healthy tissue. The system and method are useful for treating various cancers in which solid tumors form and have a chance of recurrence from microscopic disease surrounding the tumor.

A system, including various apparatus and methods, for surgical navigation is provided. The system is configured to track the spine of a patient by capturing images via one or more cameras. The cameras are configured to capture images of one or more arrays. The system transmits the images to a computer system. The one or more arrays are releasably secured with the spine of the patient, such as by a spine pin or a spine clamp. The system can determine the spatial position and orientation of relevant anatomical features, implants, and instruments using and processing the captured images.

A computer-assisted medical device includes a first articulated arm, the first articulated arm having an end effector, a first joint set, a second joint set and a control unit. The control unit configures one or more joints in the first joint set to a floating mode, detects movement of the first joint set caused by a movement of the surgical table, drives the second joint set based on the movement of the surgical table, receives an instrument motion command to move the end effector while the surgical table is moving, and moves the end effector based on the instrument motion command. In some embodiments, the instrument motion command is relative to an imaging coordinate frame. In some embodiments, the imaging coordinate frame is based on a pose of an imaging device saved prior to the movement of the surgical table.

A system to control the interaction between a user-interface of a teleoperated surgical system and an input device of the teleoperated surgical system, the system comprising a first master controller communicatively coupled to the teleoperated surgical system, a feedback control communicatively coupled to the first master controller, and a display device communicatively coupled to the teleoperated surgical system and configured to display the user interface. The feedback control is configured to restrict the movement of the first master controller based on a state of the user interface changing from a previous state.

This disclosure provides techniques and apparatuses for displaying stereoscopic video data of a target surgical site. An example ophthalmic imaging apparatus includes first and second stereoscopic lens sets configured to receive light from the target surgical site. In some embodiments, first stereoscopic lens set includes at least a first fixed focal length lens configured to magnify the received light according to a first fixed magnification level. In some embodiments, the second stereoscopic lens set includes at least a second fixed focal length lens configured to magnify the received light according to a second fixed magnification level different from the first fixed magnification level. The ophthalmic imaging apparatus also includes first and second pluralities of image sensors configured to receive the light and generate first and second image data. The first and second image data may be converted into first and second stereoscopic video data for display on a display monitor.

A console for performing a medical procedure has connection ports for electrically coupling equipment. Each connection port may have an associated indicator that signals whether a piece of equipment should be connected to the respective connection port. The indicators may be selectively activated depending on the procedure being performed with the console.

Presented herein are systems, methods, and architectures related to augmented reality (AR) surgical visualization of one or more dual-modality probe species in tissue. As described herein, near infrared (NIR) images are detected and rendered in real time. The NIR images are registered and/or overlaid with one or more radiological images (e.g., which were obtained preoperatively/perioperatively) by a processor [e.g., that uses an artificial neural network (ANN) or convolutional neural network (CNN) reconstruction algorithm] to produce a real-time AR overlay (3D representation). The AR overlay is displayed to a surgeon in real time. Additionally, a dynamic motion tracker tracks the location of fiducial tracking sensors on/in/about the subject, and this information is also used by the processor in producing (e.g., positionally adjusting) the AR overlay. The real-time AR overlay can improve surgery outcomes, for example, by providing additional real-time information about a surgical site via an intuitive visual interface.
