    Abstract: A system comprises a flexible instrument, a first user input device spaced from the flexible instrument, and a second user input device including a first state and a second state. The system further comprises a control system configured to, based on an input received from the first user input device, control an orientation of the flexible instrument. The control system is further configured to, based on an input received from the second user input device, adjust a stiffness of the flexible instrument. The stiffness of the flexible instrument is lower when the second user input device is in the first state than when the second user input device is in the second state.

    Abstract: A medical system including a flexible instrument such as a lung catheter or bronchoscope provides a control mode in which direct manual control of insertion can be used with computer-assisted control of instrument characteristics such as the orientation or rigidity of a portion of the instrument. To facilitate manual insertion control, a mechanism can provide low inertia and friction for movement along an insertion axis. One implementation employs a manual grip of the instrument for control of insertion pressure, a joystick or other input device for computer-assisted steering, and a foot pedal for control of stiffness or compliance in the instrument. Another implementation employs a joystick for computer-assisted steering and for control of stiffness or compliance in the instrument.

    Abstract: Control systems and methods for a medical instrument use measurements to determine and control the tensions that actuators apply through instrument transmission systems. The use of tension and feedback allows control of a medical instrument having transmission systems that provide non-negligible compliance between joints and actuators even when the positions of joints cannot be directly related to actuator positions. One embodiment determines joint torques and tensions from differences between desired and measured joint positions. Another embodiment determines joint torques and tensions from differences between desired and measured positions of a tip of the instrument. Determination of tensions from joint torques can be performed using sequential evaluation of joints in an order from a distal end of the instrument toward a proximal end of the instrument.

    Abstract: A medical instrument system includes a plurality of joints, a plurality of actuators, and a plurality of transmission systems. The transmission systems have proximal ends respectively coupled to the actuators. Each of the transmission systems have a distal end attached to an associated one of the joints to allow the transmission of a force for articulation of the medical instrument system. The system also includes a sensor coupled to measure a configuration of the medical instrument; and a control system coupled to receive configuration data, including a current configuration of a tip of the medical instrument from the sensor and a desired configuration of the tip of the medical instrument. Using the difference between the desired configuration and the current configuration of the tip of the medical instrument, the control system generates control signals for the actuators that cause the actuators to apply a set of tensions to the plurality of transmission systems.

    Abstract: 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.

    Abstract: 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.
