    摘要: Methods, apparatus, and systems for operating a surgical system. In accordance with a method, a position of a surgical instrument is measured, the surgical instrument being included in a mechanical assembly having a plurality of joints and a first number of degrees of freedom, the position of the surgical instrument being measured for each of a second number of degrees of freedom of the surgical instrument. The method further includes estimating a position of each of the joints, where estimating the position of each joint includes applying the position measurements to at least one kinematic model of the mechanical assembly, the kinematic model having a third number of degrees of freedom greater than the first number of degrees of freedom. The method further includes controlling the mechanical assembly based on the estimated position of the joints.

    摘要: Methods, apparatus, and systems for performing minimally invasive surgery through an aperture of a patient. In accordance with a method, parameters are received from an input device associated with a surgeon, the parameters indicating a desired state of an end effector of a surgical instrument oriented through the aperture. The surgical instrument is included in a mechanical assembly having a first set of joints. Instructions are then computed for controlling the mechanical assembly using the received parameters by computing instructions for controlling a second set joints, the second set of joints including the first set of joints and an additional joint, the additional joint being absent from the mechanical assembly. The mechanical assembly is then driven so as to move the end effector toward the desired state based on the computed instructions.

    摘要: A system and method of breakaway clutching in a computer-assisted medical device includes an articulated arm having one or more first joints and a control unit coupled to the articulated arm and having one or more processors. The control unit operates each of the first joints in multiple states. The multiple states include a locked state, wherein movement of respective first joints is restricted, and a float state, wherein movement of the respective first joints is permitted. The control unit further switches one or more second joints selected from the first joints from the locked state to the float state when a stimulus on the second joints exceeds one or more unlock thresholds and switches the second joints from the float state to the locked state when a velocity of each of the second joints is below one or more lock thresholds.
