摘要： An illustrative apparatus may perform gaze-based auto-exposure management of image frames. For example, the apparatus may determine, for an image frame within an image frame sequence captured by an image capture system, auto-exposure values for pixel units into which the image frame is divided. The apparatus may then assign weight values to the pixel units based on a gaze direction of a viewer viewing the image frame sequence. Based on the auto-exposure values determined for the pixel units and the weight values assigned to the pixel units, the apparatus may update one or more auto-exposure parameters for use by the image capture system to capture an additional image frame within the image frame sequence. Corresponding apparatuses, systems, and methods for gaze-based auto-exposure management of image frames are also disclosed.

摘要： Modified animal tissues, organs, and organ systems for use in simulated surgical procedures are disclosed. The tissues, organs, and/or organ systems can be modified by enhancing their electrical conductivity, by including simulated contents mimicking what would normally be present in live animals, and by having fake blood perfusing through them. Portions of different tissues, organs, or organ systems, which can be from the same or different animals, can be adhered to provide hybrid/chimeric tissues, organs, or organ systems, and also used for simulated surgical procedures. These modifications can provide surgeons with a more realistic experience during a simulated surgical procedure.

摘要： A computer-assisted surgical system simultaneously provides visible light and alternate modality images that identify tissue or increase the visual salience of features of clinical interest that a surgeon normally uses when performing a surgical intervention using the computer-assisted surgical system. Hyperspectral light from tissue of interest is used to safely and efficiently image that tissue even though the tissue may be obscured in the normal visible image of the surgical field. The combination of visible and hyperspectral images are analyzed to provide details and information concerning the tissue or other bodily function that were not previously available.

摘要： A medical imaging system comprises a teleoperational assembly which includes a medical instrument including an instrument tip and an imaging instrument including an imaging instrument tip. The medical imaging system also comprises a processing unit including one or more processors. The processing unit may be configured to determine an instrument tip position for the instrument tip, determine an instrument tip position error relative to the imaging instrument, and determine at least one instrument tip bounding volume based on the determined instrument tip position, the determined instrument tip position error, and a ratio between an error radius of the instrument tip position error and a size of a display screen.

摘要： A computer-assisted medical system includes a manipulator arm and an instrument holder physically coupled to the manipulator arm. The instrument holder is configured to releasably couple to an instrument. The instrument holder includes an adjustable assembly and a cannula clamp physically coupled to the adjustable assembly. A physical adjustment of the adjustable assembly moves the cannula clamp relative to the manipulator arm. The cannula clamp is configured to releasably couple to a cannula configured to receive the instrument.

摘要： Devices and methods for minimally invasive suturing are disclosed. One suturing device for minimally invasive suturing includes a proximal section a distal end, and an intermediate region therebetween. The device includes a suture head assembly having a suturing needle with a pointed end and a second end. The suturing needle is capable of rotating about an axis approximately perpendicular to a longitudinal axis of the device, wherein the pointed end of the suturing needle is positioned within the suture head assembly prior to deployment of guides that are adapted and configured to guide the needle around a circular path when advanced by a drive mechanism having a needle driver for engaging and rotating the suturing needle.

摘要： A measurement system accesses first and second images captured respectively from first and second vantage points by first and second cameras included within a stereoscopic endo scope located at a surgical area associated with a patient. The measurement system receives user input designating a user-selected two-dimensional (“2D”) endpoint corresponding to a feature within the surgical area as represented in the first image, and identifies, based on the user-selected 2D endpoint, a matched 2D endpoint corresponding to the feature as represented in the second image. Based on the user-selected and matched 2D endpoints, the measurement system defines a three-dimensional (“3D”) endpoint corresponding to the feature within the surgical area. The measurement system then determines a distance from the 3D endpoint to an additional 3D endpoint corresponding to an additional feature within the surgical area. Corresponding systems and methods are also described.

摘要： Implementations relate to detecting user touch on a controller handle. In some implementations, a non-controlling mode of a control system is activated, and in the non-controlling mode, one or more actuators are controlled to cause a vibration to be provided on a handle of a controller. The vibration is sensed with one or more sensors, and a difference in the vibration is determined to have occurred relative to a reference vibration using the one or more sensors, where the difference satisfies one or more predetermined thresholds. A controlling mode of the system is activated in response to determining the difference in the vibration, and the vibration is modified on the handle in response to detecting the change in the vibration.
