  • Binding and non-binding articulation limits for robotic surgical systems
    Patent number: 12137998
    Abstract: A robotic surgical system and method of selectively binding articulation limits to a surgical instrument includes detecting a proximal or a distal linear movement of the surgical instrument, calculating a distance between a tool center point of the surgical instrument after the proximal or the distal linear movement and a remote center of motion, assigning and binding an articulation limit to the surgical instrument based on the calculated distance when the detected linear movement is distal linear movement, and assigning a non-binding articulation limit to the surgical instrument based on the calculated distance when the detected linear movement is proximal a linear movement.
    Type: Grant
    Filed: October 29, 2019
    Date of Patent: November 12, 2024
    Assignee: Covidien LP
    Inventors: Brian Rockrohr, Eric Taylor, Matthew Hartzsch, Colin Murphy

  • Robotic surgical assemblies
    Patent number: 11179211
    Abstract: A surgical instrument for coupling to a robotic surgical assembly configured to transfer rotational forces to the surgical instrument is provided. The surgical instrument includes an elongated shaft, an end effector coupled to a distal end of the elongated shaft, and a drive assembly operatively coupled to the end effector. The drive assembly includes one or more cables connected to the end effector. Movement of the one or more cables actuates a movement of the end effector. The one or more cables may be coated with parylene.
