摘要： A teleoperational system receives a movement command in response to movement of an input device, in response to determining an instrument is being controlled based on the movement of the input device, maps the movement command to a first movement of the instrument in an instrument frame using a first mapping, and in response to determining a tissue probe is being controlled based on the movement of the input device, maps the movement command to a second movement of the tissue probe in a tissue probe frame using a second mapping. The first mapping maps motion in an input direction in the input frame to an instrument direction in the instrument frame. The second mapping maps motion in the input direction to a tissue probe direction in the tissue probe frame. The instrument direction corresponding with the input direction. The tissue probe direction not corresponding with the input direction.

摘要： A system and method of breakaway clutching in a device includes an arm having a first joint and a control unit coupled to the arm. The control unit includes one or more processors. The control unit switches the first joint from a first state of the first joint to a second state of the first joint in response to an external stimulus applied to the arm exceeding a first threshold. Movement of the first joint is more restricted in the first state than in the second state. The control unit further switches the first joint from the second state to the first state in response to a speed associated with the first joint falling below a speed threshold. The first threshold is based on at least one first property of the arm. The speed threshold is based on at least one second property of the arm.

The control unit switches the first joint from a first state of the first joint to a second state of the first joint in response to an external stimulus applied to the arm exceeding a first threshold, wherein movement of the first joint is more restricted in the first state of the first joint than in the second state of the first joint, switches the first joint from the second state to the first state in response to a speed associated with the first joint falling below a speed threshold, and prevents the switching of the first joint from the first state to the second state when the arm is in a predetermined mode.

摘要： A teleoperational medical system comprises an input device and a manipulator configured to couple with and move an instrument. The system also comprises a control system including one or more processors. In response to a determination that the instrument is inserted into an instrument workspace in a corresponding direction to a field of view of the workspace, the control system is configured to map movement of the input device to movement of the instrument according to a first mapping. In response to a determination that the instrument is inserted into the instrument workspace in a non-corresponding direction to the field of view, the control system is configured to map movement of the input device to movement of the instrument according to a second mapping. The second mapping includes an inversion of the first mapping for at least one direction of motion of the instrument.

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.
