Abstract: A system and method of variable velocity control of an instrument by a computer-assisted device includes a computer-assisted device that includes an actuator and one or more processors. To perform an operation with an instrument coupled to the computer-assisted device, the one or more processors are configured to set a velocity set point of the actuator to an initial velocity, monitor force or torque applied by the actuator to actuate the instrument, when the applied force or torque is above a first force or torque limit, determine whether a total duration of a set of pauses occurring during the operation of the instrument is below a maximum pause threshold, and in response to determining that the total duration is below the maximum pause threshold, pause the operation of the instrument.

Abstract: A medical device drive system can include a rotational input, a coupling member engaged with the rotational input, a first gear having an engagement feature sized and shaped to engage with the coupling member, and a second gear coupled with the first gear, the second gear coupled to a movable element. The system can have a first system state and a second system state. In the first system state the coupling member is not engaged with the engagement feature and the first gear rotates without moving the coupling member. In the second system state the coupling member is engaged with the engagement feature of the first gear and rotation of the rotational input turns the coupling member, the first gear, and the second gear to move the movable element.

Abstract: A surgical device includes an elongated shaft, an end effector, and a wrist assembly. The wrist assembly includes a first outer link, a first inner link, and a second outer link. The first outer link is connected to the shaft and includes first gear teeth. The first inner link is pivotally coupled with the first outer link. The second outer link is pivotally coupled with the first inner link. The second outer link includes second gear teeth that interface with the first gear teeth and control orientation of the first inner link relative to the first outer link and the first outer link throughout a range of orientations of the wrist assembly.

Abstract: A medical device drive system including a lever body having portions defining a lever body cavity, a nut housing in the lever body cavity, and a first nut at least partially in the first nut cavity. The first nut is slideable in the first nut cavity between an engaged position in which the lead screw interface is engaged with the engagement portion of the lead screw, and a disengaged position in which the lead screw interface is not engaged with the engagement portion of the lead screw. The lead screw interface of the first nut is selectively engageable with the engagement portion of the lead screw by sliding the lever body and pin relative to the first nut housing.
