Patent number: 10283220Abstract: A system and method of coordinated motion among heterogeneous devices includes a medical device with one or more movable elements and one or more processors. Any of the processors uses a shared interface to access services. The medical device requests a movement token from a token service through the shared interface, receive the movement token from the token service, exchange configuration data, kinematic data, or planned motion data through the shared interface, plan a first motion for a first movable element of the movable elements based on the movement token and the configuration data, the kinematic data, or the planned motion data, and execute the first motion. In some embodiments, the movement token is selected from a group consisting of an exclusive-motion token, a master follow-me token, a slave follow-me token, a master collision-avoidance token, a slave collision-avoidance token, and a passive collision-avoidance token.Type: GrantFiled: August 14, 2014Date of Patent: May 7, 2019Assignee: INTUITIVE SURGICAL OPERATIONS, INC.Inventors: Mahdi Azizian, Jonathan M.

Publication number: 20180153636Abstract: In a method and an apparatus to provide updated images during a robotically-implemented surgical procedure, 3D data is obtained of a volume of a patient, which includes anatomy involved in the procedure. The anatomy is segmented from a reconstructed image of the volume. During the procedure, the surgeon applies forces on the anatomy, causing a geometric change of the anatomy. Force sensors in the surgical robot detect these forces, which are supplied to a processor that controls display of the segmented anatomy at a display screen. From the applied forces and the physical properties of the anatomy, the processor calculates the geometric change of the anatomy that has occurred and modifies the appearance and/or position of the displayed segmented anatomy on the display screen in real time during the procedure, so as to visualize the geometric change.Type: ApplicationFiled: September 10, 2015Publication date: June 7, 2018Inventors: Mahdi Azizian, Lutz Blohm, Holger Kunze, Christine Niebler, Jonathan Sorger
