Abstract:
A surgical instrument is provided that includes a first input mechanism having axial slots formed in a periphery and a second input mechanism having helical slots formed in a surface. The instrument also includes an insert having pins extending from a surface thereof, the insert coupled to the second input mechanism such that the one or more pins extend into the helical slots, and a surgical device coupled to an end. The surgical device is moved in a first degree of freedom in response to a mechanical driving force applied to both the first input mechanism and the second input mechanism, respectively, and the surgical device is moved in a second degree of freedom in response to a mechanical driving force applied to the second input mechanism while the first input mechanism is held stationary.
Abstract:
In a minimally invasive surgical system, a hand tracking system tracks a location of a sensor element mounted on part of a human hand. A system control parameter is generated based on the location of the part of the human hand. Operation of the minimally invasive surgical system is controlled using the system control parameter. Thus, the minimally invasive surgical system includes a hand tracking system. The hand tracking system tracks a location of part of a human hand. A controller coupled to the hand tracking system converts the location to a system control parameter, and injects into the minimally invasive surgical system a command based on the system control parameter.
Abstract:
In one embodiment of the invention, a a minimally invasive surgical system is disclosed. The system configured to capture and display camera images of a surgical site on at least one display device at a surgeon console; switch out of a following mode and into a masters-as-mice (MaM) mode; overlay a graphical user interface (GUI) including an interactive graphical object onto the camera images; and render a pointer within the camera images for user interactive control. In the following mode, the input devices of the surgeon console may couple motion into surgical instruments. In the MaM mode, the input devices interact with the GUI and interactive graphical objects. The pointer is manipulated in three dimensions by input devices having at least three degrees of freedom. Interactive graphical objects are related to physical objects in the surgical site or a function thereof and are manipulatable by the input devices.
Abstract:
A surgical system includes a flexible steerable needle and a shape sensor for measuring the shape of the needle. The surgical system can be manual (e.g., laparoscopic), robotic, or any combination of the two. By directly measuring the shape of the needle, complex and potentially inaccurate modeling of the needle to determine trajectory and insertion depth can be avoided in favor of much more robust direct measurement and modeling of needle shape and/or pose.

Abstract:
A minimally-invasive surgical system includes a slave surgical instrument having a slave surgical instrument 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 (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 is provided for intra-surgical use of a surgical patient health record in a teleoperated surgical system that includes a surgical instrument and a surgical instrument actuator, comprising: receiving user input commands to control movement of a robotic surgical instrument; tracking robotic surgical instrument actuator state in response to the user input commands; and transitioning robotic surgical instrument actuator state to a safety mode in response to the robotic surgical instrument transitioning to a prescribed actuator state.
Abstract:
A system is configured to direct a manipulator cart to navigate, in a first bifurcated navigation control mode, from an initial location to an intermediate location; and direct the manipulator cart to navigate, in a second bifurcated navigation control mode, from the intermediate location to a target location. In the first bifurcated navigation control mode, the system is configured to autonomously control a steering of the manipulator cart while allowing operator control of a propulsion of the manipulator cart using a primary control interface configured to facilitate operator control of both steering and propulsion of the manipulator cart. In the second bifurcated navigation control mode, the system is configured to autonomously control the steering of the manipulator cart while allowing operator control of the propulsion of the manipulator cart using a secondary control interface configured to facilitate operator control of the propulsion and not the steering of the manipulator cart.
Abstract:
A mixed reality presentation system identifies an operating condition associated with an operation performed on a body while an active imaging device captures imagery of an internal view of the body. The mixed reality presentation system also determines, based on the identified operating condition, that a display device is to toggle a display of a shape overlay that is displayed together with an external view of the body and that is indicative of an extent of a field of view of the active imaging device relative to the body. Based on the determining that the display device is to toggle the display of the shape overlay, the mixed reality presentation system directs the display device to toggle the display of the shape overlay. Corresponding systems and methods are also disclosed.
