摘要:
In a minimally invasive surgical system, a plurality of video images is acquired. Each image includes a hand pose image. Depth data for the hand pose image is also acquired or synthesized. The hand pose image is segmented from the image using the depth data. The segmented image is combined with an acquired surgical site image using the depth data. The combined image is displayed to a person at a surgeon's console of the minimally invasive surgical system. Processing each of the video images in the plurality video images in this way reproduces the hand gesture overlaid on the video of the surgical site in the display.

A stereo imaging system comprises a stereoscopic camera having left and right image capturing elements for capturing stereo images; a stereo viewer; and a processor configured to modify the stereo images prior to being displayed on the stereo viewer so that a disparity between corresponding points of the stereo images is adjusted as a function of a depth value within a region of interest in the stereo images after the depth value reaches a target depth value.

Provided are a system and method for image sharpening is provided that involves capturing an image, and then decomposing the image into a plurality of image-representation components, such as RGB components for example. Each image-representation component is transformed to obtain an unsharpened multi-resolution representation for each image-representation component. A multi-resolution representation includes a plurality of transformation level representations. Sharpness information is transported from an unsharpened transformation level representation of a first one of the image-representation components to a transformation level representation of an unsharpened multi-resolution representation of a second one of the image-representation components to create a sharpened multi-resolution representation of the second one of the image-representation components. The sharpened multi-resolution representation of the second one of the image-representation components is then transformed to obtain a sharpened image. The improved and sharpened image may then be displayed.

In a minimally invasive surgical system, a hand tracking system tracks a location of a sensor element mounted on part of a human hand. A system control parameter is generated based on the location of the part of the human hand. Operation of the minimally invasive surgical system is controlled using the system control parameter. Thus, the minimally invasive surgical system includes a hand tracking system. The hand tracking system tracks a location of part of a human hand. A controller coupled to the hand tracking system converts the location to a system control parameter, and injects into the minimally invasive surgical system a command based on the system control parameter.

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.

摘要:
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.

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.

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.
摘要:
A surgical method is provided for use with a teleoperated surgical system (surgical system), the method comprising: recording surgical instrument kinematic information indicative of surgical instrument motion produced within the surgical system during the occurrence of the surgical procedure; determining respective kinematic signatures associated with respective surgical instrument motions; producing an information structure in a computer readable storage device that associates respective kinematic signatures with respective control signals; comparing, during a performance of the surgical procedure surgical instrument kinematic information during the performance with at least one respective kinematic signature; launching, during a performance of the surgical procedure an associated respective control signal in response to a match between surgical instrument kinematics during the performance and a respective kinematic signature.
