MULTI-POSITION RESTRAINING MEMBER FOR SLED MOVEMENT
A surgical instrument includes a body, a shaft assembly, an end effector, a stapling assembly, and a restriction feature. The shaft assembly extends distally from the body. The end effector being on a distal end of the shaft assembly and incudes a first second jaw. The stapling assembly is supported by one of the first jaw or the second jaw. The stapling assembly includes a wedge sled. The wedge sled is configured to move relative to the one of the first jaw or the second jaw to drive movement of one or more staples. The restriction feature is configured to releasably hold the wedge sled in a predetermined position within the stapling assembly while the stapling assembly is in a pre-fired configuration. At least a portion of the restriction feature is configured to respond to movement of the edge sled to release the restriction feature from the wedge sled.
Control device and master slave system
Provided is a control device including a control unit that calculates a first positional relationship between an eye of an observer observing an object displayed on a display unit and a first point in a master-side three-dimensional coordinate system, and controls an imaging unit that images the object so that a second positional relationship between the imaging unit and a second point corresponding to the first point in a slave-side three-dimensional coordinate system corresponds to the first positional relationship.
SURGICAL ROBOT PLATFORM
A medical robot system, including a robot coupled to an effectuator element with the robot configured for controlled movement and positioning. The system may include a transmitter configured to emit one or more signals, and the transmitter is coupled to an instrument coupled to the effectuator element. The system may further include a motor assembly coupled to the robot and a plurality of receivers configured to receive the one or more signals emitted by the transmitter. A control unit is coupled to the motor assembly and the plurality of receivers, and the control unit is configured to supply one or more instruction signals to the motor assembly. The instruction signals can be configured to cause the motor assembly to selectively move the effectuator element.
Devices, Systems, and Methods for Anchoring Actuation Wires to a Steerable Instrument
A pull wire attachment system for a minimally invasive medical instrument comprises an anchoring element fixedly attached to the medical instrument. The anchoring element has a first outer diameter. The system also includes a pull wire assembly comprising an elongate pull wire having a proximal end and a distal end and a securing element coupled to the distal end of the pull wire. The securing element includes a second outer diameter sized smaller than the first outer diameter of the anchoring element. The securing element is coupled to the anchoring element to prevent proximal translation of the distal end of the pull wire along a longitudinal axis of the medical instrument past the anchoring element.
Method and system for hand tracking in a robotic system
A method and system for hand tracking in a robotic system includes a hand tracking system and a controller coupled to the hand tracking system. The controller is configured to receive, from the hand tracking system, a plurality of locations of a hand; determine if the hand is in a first hand pose based on the plurality of locations; in response to determining that the hand is in the first hand pose, and switch the robotic system to a hand trajectory detection mode. While in the hand trajectory detection mode, the control unit is configured to detect, based on hand tracking information from the hand tracking system, that the hand has performed a first hand trajectory of a plurality of known hand trajectories; and in response to detecting the first hand trajectory, change a mode of operation of the robotic system.
Force-feedback gloves for a surgical robotic system
A surgical robotic system that includes a robotic arm, glove configured to be worn on a hand of a user and including a force-feedback mechanism, a tracking device, a processor, and memory. The memory includes instructions which when executed by the processor causes the system to determine that the user is performing a hand gesture with the glove to grasp a virtual user input device (UID) based on the tracking device, and in response to the user grasping the virtual UID, apply, via the force-feedback mechanism, a force upon the glove that corresponds to a physical representation of the virtual UID, and engage the robotic arm to be controlled by the virtual UID.
Systems and methods for entering and exiting a teleoperational state
A teleoperational medical system includes a teleoperational control system, a teleoperational manipulator, an operator controller. The control system includes a processing unit configured to: determine a position and orientation of a marker on an operator of the operator controller; determine whether a head portion of the operator is directed toward or away from a display region of a display; based on a determination that the head portion is directed toward the display region, initiate an operator following mode in which a movement of the operator controller provides a corresponding movement to the teleoperational manipulator; and based on a determination that the head portion is directed away, suspend the operator following mode. The determination that the head portion is directed away from the display region of the display device includes determining whether the head portion of the operator is directed away from the display region for a threshold time period.
Communicating closure effort for robotic surgical tools background
A method includes grasping a user input device in communication with a surgical tool of a robotic surgical system, the surgical tool including an end effector with opposing jaws, squeezing the user input device and thereby actuating a motor that closes the jaws and clamps down on tissue at a surgical site, and calculating with a computer system in communication with the surgical tool work completed by the motor to close the jaws and clamp down on the tissue. The computer system generates one or more effort indicators when the work completed by the motor meets or exceeds one or more predetermined work increments corresponding to operation of the motor, and communicates the one or more effort indicators to an operator.
User controller with user presence detection and related systems and methods
The present invention is relates to a user controller having a thumb sheath with an open side defined in the thumb sheath. Further embodiments relate to thumb presence sensors and sensory feedback components associated with the thumb sheath. Additional embodiments relate to an adjustable thumb sheath. Still other embodiments relate to systems comprising such user controllers.
Methods for performing medical procedures using a surgical robot
Embodiments are directed to a medical robot system including a robot coupled to an end-effectuator element with the robot configured to control movement and positioning of the end-effectuator in relation to the patient. One embodiment is a method for removing bone with a robot system comprising: taking a two-dimensional slice through a computed tomography scan volume of target anatomy; placing a perimeter on a pathway to the target anatomy; and controlling a drill assembly with the robot system to remove bone along the pathway in the intersection of the perimeter and the two-dimensional slice.
