  • Patent number: 10716568
    Abstract: A surgical stapling assembly comprising a staple cartridge carrier, an anvil, an outer surface, a closure member, a staple cartridge, and a firing system is disclosed. The anvil is rotatable between a first position and a second position. The closure member is slideable along the outer surface to hold the anvil in the second position. The closure member comprises a clearance opening. The staple cartridge is positioned within the staple cartridge carrier. The staple cartridge comprises staples removably stored therein. The staple cartridge and the anvil define a tissue gap therebetween when the anvil is in the second position. The clearance opening is aligned with the tissue gap when the anvil is in the second position. The firing system is configured to eject the staples from the staple cartridge during a staple firing stroke. The firing system engages the staple cartridge carrier and the anvil during the staple firing stroke.

  • Patent number: 10637911
    Abstract: Embodiments of the disclosed subject matter include a communication interface and protocol for allowing communication between devices, circuits, integrated circuits, and other electronic components having, for example, different communication capacities or clock domains. The interface supports communication between any components having any difference in capacity and over any distance. The interface utilizes request and acknowledge phases and signals and an initiator-target relationship between components that allow each side to throttle the communication rate to an accepted level for each component or achieve a desired bit error rate. Other devices, methods, and interfaces are disclosed.

  • Publication number: 20200078108
    Abstract: A system includes a controller communicatively coupled to an illuminator and to a camera configured to capture a scene including tissue. The controller may change the output optical power of the illuminator from a first output optical power to a second output optical power so that a subsequently captured frame is captured by the camera from reflected light, the reflected light being light from the illuminator having the second output optical power prior to being reflected. The controller may determine that an endoscope contacted the tissue if the change of the output optical power of the illuminator results in a change of a reflected luminance that is less than a predetermined threshold, the change of the reflected luminance being a change from a first reflected luminance for the first output optical power to a second reflected luminance for the second output optical power.

  • Publication number: 20200077870
    Abstract: A system may control an illuminator to illuminate a surgical site with non-white light and control a camera to capture light reflected from the surgical site. The camera may separate the captured light into a plurality of color components. The plurality of color components may be captured by the camera as a plurality of sets of pixels of a frame in a video stream, and each set of the plurality of sets of pixels may be in a different color channel of the camera. The system may further control, based on color component characteristics of the light captured by the camera, the illuminator to configure the non-white light such that each color channel of the camera has an about equal response to the light captured by the camera for a subsequently captured frame in the video stream.

  • Patent number: 10512512
    Abstract: Scenes captured with an endoscope (201) of a teleoperated surgical system (200) and displayed on a display unit (251) maintain a consistent brightness even though optical output power of an illuminator (210) changes, and working distance (204) between tissue (203) and the distal tip of the endoscope changes. Teleoperated surgical system (200) also automatically detects when endoscope (201) contacts tissue (203) and adjusts the output optical power of illuminator (210) so that tissue damage does not occur.

  • Patent number: 10506914
    Abstract: Non-white light from an endoscope (201) of a teleoperated surgical system (200) is used to illuminate a surgical site (203). A camera (220L) captures an image of the surgical site, and the image is displayed on a monitor (251). The non-white light illumination minimizes noise in the images of the surgical site presented on the monitor relative to images captured using white light illumination and displayed on the monitor.

  • Publication number: 20190200848
    Abstract: 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.
