  • Patent number: 11517325
    Abstract: A motorized surgical instrument is disclosed. The surgical instrument includes a displacement member, a motor coupled to the displacement member, a control circuit coupled to the motor, a position sensor coupled to the control circuit, and a timer circuit coupled to the control circuit. The timer circuit is configured to measure elapsed time and to to receive, from the position sensor, a position of the displacement member in a current zone during a set time interval, measure displacement of the displacement member at a set time at the end of the set time interval, wherein the measured displacement is defined as the distance traveled by the displacement member during the set time interval at a set command velocity for the current zone, and set a command velocity of the displacement member for a subsequent zone based on the measured displacement of the displacement member within the current zone.

  • Publication number: 20220336078
    Abstract: A tracking system of operating room (OR) personnel and is configured to extrapolate the movement, position, orientation, and context of one or more of the active OR participants to determine the specific operation procedure in progress, the surgical instrument being used by the OR participant, and/or anticipated movement of the OR personnel. The system may further be configured to render a virtual element that includes an anticipated position of a surgical instrument, recommendations, guidance, warning, and surgical location information, as augmented reality (AR) content. The AR content is integrated in real-time with the live-feed of the surgical site, and aids the OR personnel in perioperative surgical procedures.

  • Patent number: 11116532
    Abstract: A surgical instrument, has an end effector that includes an ultrasonic blade, and a clamp arm that moves relative to the ultrasonic blade from an opened position toward an intermediate position and a closed position. The clamp arm is offset from the ultrasonic blade to define a predetermined gap in the intermediate position between the opened position and the closed position. A clamp arm actuator connects to the clamp arm and moves from an opened configuration to a closed configuration to direct the clamp arm from the opened position toward the intermediate position and the closed position. A spacer connects with the clamp arm to inhibit movement of the clamp arm from the intermediate position toward the closed position for maintaining the predetermined gap between the clamp arm and the ultrasonic blade.

  • Publication number: 20210244407
    Abstract: Methods of controlling velocity of a firing member in a robotic surgical system are disclosed. One method detects an end effector condition during closure, sets a command velocity of a displacement member based on the closure condition, fires the displacement member at the set command velocity, detects an end effector condition during a firing phase, and sets a command velocity based on the firing condition. Another method receives closure force of a closure member, compares the actual closure force to a threshold, determines a set point velocity based on the comparison, and controls the actual velocity of the closure member based on the set point velocity. Another method receives actual closure force of a closure member, receives actual position of a firing member, and sets a new closure force based on the actual closure force applied to the closure member and the actual position of the firing member.
