A system and method for navigating to a target using fluoroscopic-based three dimensional volumetric data generated from two dimensional fluoroscopic images, including a catheter guide assembly including a sensor, an electromagnetic field generator, a fluoroscopic imaging device to acquire a fluoroscopic video of a target area about a plurality of angles relative to the target area, and a computing device. The computing device is configured to receive previously acquired CT data, determine the location of the sensor based on the electromagnetic field generated by the electromagnetic field generator, generate a three dimensional rendering of the target area based on the acquired fluoroscopic video, receive a selection of the catheter guide assembly in the generated three dimensional rendering, and register the generated three dimensional rendering of the target area with the previously acquired CT data to correct the position of the catheter guide assembly.

An augmented reality interventional system which provides contextual overlays (116) to assist or guide a user (101) or enhance the performance of the interventional procedure by the user that uses an interactive medical device (102) to perform the interventional procedure. The system includes a graphic processing module (110) that is configured to generate at least one contextual overlay on an augmented reality display device system (106). The contextual overlays may identify a component (104) or control of the interactive medical device. The contextual overlays may also identify steps of a procedure to be performed by the user and provide instructions for performance of the procedure. The contextual overlays may also identify a specific region of the environment to assist or guide the user or enhance the performance of the interventional procedure by identifying paths or protocols to reduce radiation exposure.

Embodiments are directed to a medical robot system including a robot coupled to an end-effectuator element with the robot configured to control movement and positioning of the end-effectuator in relation to the patient. One embodiment is a method for removing bone with a robot system comprising: taking a two-dimensional slice through a computed tomography scan volume of target anatomy; placing a perimeter on a pathway to the target anatomy; and controlling a drill assembly with the robot system to remove bone along the pathway in the intersection of the perimeter and the two-dimensional slice.

A virtual model a planned instrument attachment can be provided to ensure correct selection of a physical instrument attachment. An XR headset controller can generate a shape and a pose of the virtual model of the planned instrument attachment based on predetermined information associated with the planned instrument attachment and based on a pose of an instrument relative to the XR headset. An XR headset can display the virtual model on a see-through display screen of the XR headset that is configured to allow at least a portion of a real-world scene to pass therethrough.

A robotic medical system can include a motorized arm that is supported by a column of the system. The robotic arm can be operated by rotating a link of the motorized arm by actuating an actuator to drive rotation of a rotary joint. A brake can then be applied to the rotary joint to stop rotation of the link. The arm can also include an arbor that can be actuated to increase a torsional stiffness of the rotary joint.

Provided is a laser projection apparatus, a control method thereof, and a laser guidance system including the laser projection apparatus. The laser projection apparatus for projecting planned operation information of an insertion location and an insertion angle on a C-arm image photographed using a C-arm fluoroscopy device directly onto an affected part includes a line laser module configured to generate a line laser and to form a plane by rotating around an origin, a matching unit configured to calculate a coordinate representing the insertion location in a C-arm coordinate system based on C-arm fluoroscopy, calculate an insertional vector according to the coordinate representing the insertion location and the insertion angle, and calculate a vector perpendicular to the plane formed by the line laser in the C-arm coordinate system according to the insertional vector, and a control unit configured to control the line laser module based on the vector perpendicular to the plane.

Certain aspects relate to systems and techniques for articulating medical instruments. In one aspect, the instrument includes a wrist having at least two degrees of freedom of movement, and an end effector coupled to the wrist. The end effector can include an upper jaw, a lower jaw, and a firing mechanism configured to form staples in tissue. Actuation of the firing mechanism can be decoupled from the movement of the wrist in the at least two degrees of freedom.

A path preparation system for preparing a path for a device. The path preparation system includes an ultrasound transmitter and a tracking system. The tracking system is configured to determine a current position of the device on the path. The ultrasound transmitter is configured to focus an ultrasound wave onto a focus position that lies in front of the device in the direction of the path, in spatial relation to the current position of the device.

Systems and methods are provided for processing X-ray images, wherein the methods are implemented as a software program product executable on a processing unit of the systems. Generally, an X-ray image is received by the system, the X-ray image being a projection image of a first object and a second object. The first and second objects are classified and a respective 3D model of the objects is received. At the first object, a geometrical aspect like an axis or a line is determined, and at the second object, another geometrical aspect like a point is determined. Finally, a spatial relation between the first object and the second object is determined based on a 3D model of the first object, a 3D model of the second object, and the information that the point of the second object is located on the geometrical aspect of the first object.

A technique of generating surgical information from intra-operatively acquired image data of vertebrae and pre-operatively acquired image data of the vertebrae is presented. A method implementation includes obtaining first image segments each containing a different vertebra, and second image segments each containing a different vertebra. The first image segments have been derived by processing the pre-operatively acquired image data, and the second image segments have been derived by processing the inter-operatively acquired image data. The method includes identifying one of the second image segments and one of the first image segments that contain the same vertebra, and determining a transformation that registers the identified first image segment and the identified second image segment. The method includes generating surgical information based on the transformation and the identified first image segment.
