A method and system utilizes an imaging device that generates images of target tissue of a patient during a surgical procedure that acts on the target tissue imaged by the imaging device. The method and system enables visual detection of patient movement during the surgical procedure by marking at least one spatial attribute of one or more identifiable features of the target tissue illustrated in an image presented in a display window. Prior to acting on the target tissue, a visual indicator of the spatial attribute(s) is superimposed on one or more subsequent images captured by the imaging device and displayed to the operator. The operator can visually compare a position of the visual indicator to a position of the operator-identified feature in order to detect movement of the patient during the procedure. The system and methodology also facilitates realignment that corrects for detected patient movement.

A surgical system includes a first surgical instrument having a selected configuration and an image guide disposed relative to a sensor to communicate a signal representative of a position of the image guide. A passive image guide is fixed with vertebral tissue and is disposed relative to the sensor to communicate a signal representative of a position of the passive image guide. The passive image guide includes a first surface. A second surgical instrument is connectable with the first surgical instrument and includes a second surface engageable with the first surface in a mating configuration to provide verification of the selected configuration. Surgical instruments, implants, spinal constructs and methods are disclosed.

A system comprises a robotic arm in a robotic arm coordinate system, a camera in a fixed pose in a navigation coordinate system, at least one processor, and memory including instructions that when executed by the at least one processor, cause the at least one processor to determine a pose of the robotic arm within the navigation coordinate system, map the robotic arm coordinate system to the navigation coordinate system based on the pose of the robotic arm, and control, based on output of the camera, the robotic arm in the navigation coordinate system.

The present invention is a method for controlling a Davinci surgical device. Firstly, controlling an operation part of a remote operation device to enter the inner of a body for executing a surgical operation. Then, an image capturing unit captures a plurality of corresponding surgical images to a control device, and the control device obtains a first torque component, a second torque component and an element action of the remote surgical device according to the surgical images to operate an output strength of the remote surgical device for further generating corresponding strength feedback by the output strength. Thus, the user can get the control status of the remote surgical device to prevent accidental iatrogenic injury from over-force and to proceed with the operation with improved accuracy.

A method for displaying guidance information using a graphical user interface during an medical procedure comprises displaying, in a first mode of the graphical user interface, first image data from a perspective corresponding to a distal end of an elongate device. The first image data includes a virtual roadmap. The method also comprises transitioning from the first mode of the graphical user interface to a second mode of the graphical user interface. The transition is based on an occurrence of a triggering condition. The method also comprises displaying, in the second mode of the graphical user interface, second image data from a perspective corresponding to the distal end of the elongate device. The second image data includes a target indicator corresponding to a target location and an alignment indicator corresponding to an expected location of the medical procedure at the target location.

Systems and methods for capturing and rendering light fields for head-mounted displays are disclosed. A mediated-reality visualization system includes a head-mounted display assembly comprising a frame configured to be mounted to a user's head and a display device coupled to the frame. An imaging assembly separate and spaced apart :from the head-mounted display assembly is configured to capture light-field data. A computing device in communication with the imaging assembly and the display device is configured to receive light-field data from the imaging assembly and render one or more virtual cameras. Images from the one or more virtual cameras are presented to a user via the display device.

A method may be provided to operate a medical system. First data may be provided for a first 3-dimensional (3D) image scan of an anatomical volume, with the first data identifying a blood vessel node in a first coordinate system for the first 3D image scan. Second data may be provided for a second 3D image scan of the anatomical volume, with the second data identifying the blood vessel node in a second coordinate system for the second 3D image scan. The first and second coordinate systems for the first and second 3D image scans of the anatomical volume may be co-registered using the blood vessel node identified in the first data and in the second data as a fiducial.

Systems and methods for treating tissue are disclosed. The target tissue is ablated. A real-time image of the target tissue is generated during the ablation. The real-time blood perfusion level of the target tissue is determined from the real-time image and compared to an initial blood perfusion level of the target tissue. The comparison provides a metric for the progress of the ablation, and ablation is halted when the real-time blood perfusion drops below a threshold level relative to the initial blood perfusion level.
