  • Patent number: 11307430
    Abstract: An optical device, generally a camera head connected to an endoscope, provides multiple modes of operation, producing images with varying depth of field and/or resolution characteristics. Light from the endoscope passes through a variable aperture and a beam splitter and is directed to two or more independent image sensors. The image sensors may be moved, relative to each other, along their optical paths. An image processor combines the collected images into a resultant image. Adjustment of the relative positions of the image sensor and/or the diameter of the variable aperture permits the selection of optical properties desired, with a larger depth of field, and/or higher resolution than possible with a conventional system. Images may be collected through multiple acquisition periods, and a further enhanced image may be generated therefrom. The camera head may automatically make adjustments based on identifiers of the optical configuration of the attached endoscope.

  • Patent number: 11284790
    Abstract: A Laparoscopic Visualization System comprising a sterile, self-contained, disposable apparatus used in medical procedures for heating and applying an anti-fog solution to the distal end of laparoscopes or surgical devices is presented. It additionally serves as an endoscopic lens protector and cleaner. An efficient heating and narrow range temperature control mechanism is used in combination with an anti-fog solution to provide clear visualization through a distal lens of the surgical device inserted into the system. The configuration prevents the anti-fog solution from spilling out of the system and is designed to also be used as a holder for the surgical scope, protecting the distal lens from impact with a shock absorbent outer shell, prior to, during, and after a medical procedure.

  • Patent number: 11166774
    Abstract: Trocar placement locations may be identified, before forming incisions in a patient, by visualizing reach of a surgical instrument relative to a surgical site within the patient. The reach of the surgical instrument is calculated from the position of a robotic manipulator associated therewith. An image of the reach of the surgical instrument may be generated, which a clinician may utilize to ascertain whether the surgical instrument has adequate access to the surgical site. The clinician may move the robotic manipulator to a new position relative to the surgical site and, as the robotic manipulator is repositioned, the image of the reach of the surgical instrument generated is continuously updated to correspond with the new position into which the robotic manipulator associated therewith has been moved.
