Abstract:
A minimally-invasive surgical system includes a slave surgical instrument having a slave surgical instrument tip and a master grip. The slave surgical instrument tip has an alignment in a common frame of reference and the master grip, which is coupled to the slave surgical instrument, has an alignment in the common frame of reference. An alignment error, in the common frame of reference, is a difference in alignment between the alignment of the slave surgical instrument tip and the alignment of the master grip. A ratcheting system (i) coupled to the master grip to receive the alignment of the master grip and (ii) coupled to the slave surgical instrument, to control motion of the slave by continuously reducing the alignment error, as the master grip moves, without autonomous motion of the slave surgical instrument tip and without autonomous motion of the master grip.

Abstract:
A robotic system includes a processor that is programmed to determine and cause work site measurements for user specified points in the work site to be graphically displayed in order to provide geometrically appropriate tool selection assistance to the user. The processor is also programmed to determine an optimal one of a plurality of tools of varying geometries for use at the work site and to cause graphical representations of at least the optimal tool to be displayed along with the work site measurements.
Abstract:
An operator telerobotically controls tools to perform a procedure on an object at a work site while viewing real-time images of the object, tools and work site on a display. Tool information is provided by filtering a part of the real-time images for enhancement or degradation to indicate a state of a tool and displaying the filtered images on the display.
Abstract:
Embodiments of an instrument manipulator are disclosed. An instrument manipulator can include a track; a translational carriage coupled to ride along the track; a shoulder yaw joint coupled to the translational carriage; a shoulder pitch joint coupled to the shoulder yaw joint, the shoulder pith joint including an arm, a wrist mount coupled to the arm, struts coupled between the wrist mount and the shoulder yaw joint, and a shoulder pitch mechanism coupled to the arm; a yaw-pitch-roll wrist coupled to the wrist mount, the yaw-pitch-roll wrist including a yaw joint and a differentially driven pitch-roll joint; and an instrument mount coupled to the wrist. The various joints and carriages can be driven by motors.
Abstract:
A method is provided to produce a multi-modality image of a surgical scene comprising: capture light reflected from the surgical scene; producing first image information corresponding to a first modality image; producing second image information corresponding to a second modality image; selecting a portion of the second image modality based at least in part upon anatomical structure information included within the selected portion; and producing simultaneously within a display at least a portion of the first modality image of the surgical scene and the selected portion of the second modality image.
Abstract:
A bifurcated navigation control system is configured to identify a navigation condition associated with a navigation of a component of a computer-assisted medical system component along a path from an initial location to a target location; determine, based on the navigation condition, a propulsion limitation configured to be imposed on operator-provided commands related to a propulsion of the component during the navigation of the component along the path; and direct the component to navigate, in a bifurcated navigation control mode, along at least part of the path from the initial location to the target location. In the bifurcated navigation control mode, the bifurcated navigation control system is configured to autonomously control a steering of the component while allowing operator control of the propulsion of the component based on the operator-provided commands as limited by the propulsion limitation.
Abstract:
A region-based augmentation system is configured to determine that a viewpoint of a user of a display device is directed within an anchor region of a physical world containing the user. In response, the system directs the display device to present augmented content in an evident manner. The evident manner comprises anchoring the augmented content relative to the viewpoint, such that the augmented content follows the viewpoint as the user moves the viewpoint within the anchor region. The system further determines that the viewpoint is directed outside of the anchor region by the user. In response, the system directs the display device to present the augmented content in a less evident manner. The presenting of the augmented content in the less evident manner comprises presenting the augmented content less visibly than the evident manner and/or unanchoring the augmented content relative to the viewpoint. Corresponding methods and systems are also disclosed.
Abstract:
A system comprises: a robotic arm operatively coupleable to a tool comprising a working end; and an input device communicatively coupled to the robotic arm. The input device is manipulatable by an operator. The system further comprises a processor configured to cause an image of a work site, captured by an image capture device from a perspective of an image reference frame, to be displayed on a display. The image of the work site includes an image of the working end of the tool. The processor is further configured to determine a position of the working end of the tool in the image of the work site and render a tool information overlay at the position of the working end of the tool in the image of the work site. The tool information overlay visually indicates an identity of the input device.
Abstract:
A computer-assisted system includes a manipulator arm coupled to an active imaging device and one or more processors configured to perform a process comprising: automatically directing a display device to display a shape overlay overlaid with an external view of a body, wherein the shape overlay is indicative of an extent of a field of view of the active imaging device relative to the body, and automatically directing the display device to display an auxiliary shape overlay overlaid with the external view of the body, wherein the auxiliary shape overlay is indicative of an extent of a potential field of view of the active imaging device relative to the body, the potential field of view distinct from the field of view.
