  • Publication number: 20240216090
    Abstract: A system comprises a sensing means for sensing an arrangement of a manipulator assembly. The system further comprises a control means for: determining a motion limit of the manipulator assembly based on the sensed arrangement; and selecting a threshold limit from a plurality of pre-stored threshold limits based on which procedure type is to be performed with the manipulator assembly. The selected threshold limit is associated with a procedure type and defines a limit of a range to be potentially travelled by the manipulator assembly to perform a procedure. The control means are further for: comparing the motion limit to the selected threshold limit to determine whether the selected threshold limit is outside a range of motion bounded by the motion limit; and providing a notification indicative of whether the selected threshold limit is outside the range of motion bounded by the motion limit.

  • Patent number: 12016646
    Abstract: A computer-assisted surgical system includes a function selection system configured to detect an actuation and a de-actuation of a user input mechanism associated with a user control mechanism for controlling a surgical instrument coupled to a manipulator arm of a computer-assisted surgical system, the user input mechanism configured to facilitate activation and deactivation of a clutch mode of operation in which the user control mechanism is decoupled from controlling the surgical instrument. Based on the detecting of the actuation and the de-actuation of the user input mechanism, the function selection system determines information associated with the user input mechanism and the user control mechanism, compares the information to a set of defined criteria, and performs, when the information satisfies the set of defined criteria, a function associated with a different mode of operation of the computer assisted surgical system.
