  • Publication number: 20210137544
    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.

  • Patent number: 10932772
    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.
