Abstract:
A robotic system comprises a display that is viewable by an operator. An operator reference frame is defined relative to the display or the operator viewing the display. The robotic system also includes an input device movable by the operator and a processing unit. The processing unit is configured to present, in the display, a first image of a first tool captured by an imaging device, receive, from the operator, a first indication that a first axis of the input device is aligned with a corresponding axis of the first tool in the first image, and in response to the first indication, determine a first alignment relationship between the imaging device and the first tool based on a second alignment relationship between the operator reference frame and the input device.
Abstract:
Systems and methods for guided port placement selection include receiving a patient model, identifying a plurality of port locations on the patient model for accessing a workspace using a plurality of instruments controlled by a computer-assisted device and displaying one or more of the combinations of the plurality of port locations to a user along with a corresponding aggregate metric. For each of the port locations, the method includes determining a collision volume for portions of the computer-assisted device proximal to the port location, a reachability metric, and an anthropomorphic metric. For each combination of the plurality of port locations, the method includes determining a collision metric based on overlaps of the collision volumes for the port locations in the combination, and an aggregate metric for the combination.
Abstract:
A system and method of recentering imaging devices and input controls includes a medical device having one or more end effectors, an imaging device, one or more input controls for teleoperating the one or more end effectors, and a control unit including one or more processors coupled to the end effectors, the imaging device, and the input controls. The control unit suspends teleoperated control of the end effectors by the input controls in response to a recentering request, determines a view recentering move for the imaging device so that the end effectors are contained within a view space of the imaging device, determines one or more input control recentering moves to provide positional and orientational harmony between each of the input controls and a corresponding one of the end effectors, executes the view and input control recentering moves, and reinstates teleoperated control of the end effectors by the input controls.
Abstract:
A minimally- invasive surgical system (100) includes a slave surgical instrument having a slave surgical instrument (112) tip and a master grip. The slave surgical instrument tip has an alignment in a common frame of reference and the master grip, which is coupled to the slave surgical instrument, has an alignment in the common frame of reference. An alignment error, in the common frame of reference, is a difference in alignment between the alignment of the slave surgical instrument tip and the alignment of the master grip. A ratcheting system (130) (i) coupled to the master grip to receive the alignment of the master grip and (ii) coupled to the slave surgical instrument, to control motion of the slave by continuously reducing the alignment error, as the master grip moves, without autonomous motion of the slave surgical instrument tip and without autonomous motion of the master grip.

Abstract:
A method comprises displaying a surgical environment image. The surgical environment image includes a virtual control element for controlling a component of a surgical system. The method also includes displaying an image of a body part of a user used to interact with the virtual control element. The method also comprises receiving a user input from the user with a gesture based input device while the body part interacts with the virtual control element. The method also comprises adjusting a setting of the component of the surgical system based on the received user input.
Abstract:
Systems and methods for reassigning control by a master controller between a plurality of teleoperational instruments is provided herein. An exemplary method includes detecting activation of an instrument reassignment input, computing proxy positions of at least a first instrument and a second instrument of the plurality of teleoperational instruments, and computing a proxy position of the master controller. The exemplary method may also include receiving input from the master controller associating the proxy position of the master controller with the proxy position of the second medical instrument and assigning control of the second instrument to the master controller based on the association between the proxy position of the master controller with the proxy position of the second instrument.
Abstract:
A method is provided for use with a teleoperated surgical system, the method comprising: determining patient position information during a setup for a performance of the surgical procedure within an instance of the surgical system; determining a match between the determined patient position and a patient position signature; and launching a support arm control signal within the surgical system that corresponds to the matched support arm signature.
Abstract:
A system comprises a teleoperational assembly including an operator control system and a teleoperational manipulator configured for operation by the operator control system. The teleoperational manipulator is coupled to a medical instrument in a surgical environment. The system also comprises a processing unit including one or more processors. The processing unit is configured to retrieve a user profile for a user. The user profile including a parameter established during a prior teleoperational procedure. The processing unit is also configured to provide instructions to configure an operation of the teleoperational assembly based upon the parameter.
Abstract:
A medical imaging system comprises a teleoperational assembly configured to control the movement of a medical instrument including an instrument tip and a processing unit including one or more processors. The processing unit is configured to determine an instrument tip position and determine a position error associated with the instrument tip position. The processing unit is also configured to determine at least one instrument tip bounding volume based upon the position error and determine if the instrument tip is within a field of view of an imaging instrument.
