  • Publication number: 20230285097
    Abstract: A cannula includes a funnel portion and a tubular portion extending distally from the funnel portion. The tubular portion defines a longitudinal axis. An inner lumen extending through the tubular portion permits a medical instrument to be advanced or retracted through the tubular portion. A first visual indicator on the tubular portion is indicative of a first defined remote center of motion about which the tubular portion is pivotable by a robotic system, and a second visual indicator on the tubular portion and spaced apart axially from the first visual indicator is indicative of a second defined remote center of motion about which the tubular portion is pivotable by a robotic system.
