Controllers for robotically enabled teleoperated systems
A robotically enabled teleoperated system can include a controller and a robotic tool capable of manipulation by the controller. The controller can include a handle, a gimbal and a positioning platform. The handle can be configured for actuation by an operator to cause a corresponding manipulation of the robotic tool. The gimbal can include a joint and a load cell. The joint can be configured to be manipulated based on an impedance control, such that manipulation of the gimbal causes a corresponding manipulation of the robotic tool based on a displacement of the joint. A portion of the positioning platform can be configured to be manipulated based on an admittance control, such that manipulation of the positioning platform causes a corresponding manipulation of the robotic tool based on a force imparted on the controller and measured by the load cell.
Method and system for color based indication of suture strain
Methods and systems for providing a visual indication of suture strain include detecting a force applied to the suture; obtaining an image including the suture; identifying, based on at least one of an algorithm to convert a plurality of forces to a plurality of colors or in a table that associates a plurality of colors to a plurality of forces, respectively, a color associated with the force applied to the suture; generating an augmented version of the image; and displaying the augmented version of the image, where the identified color is used to represent at least a portion of the suture.
Systems and methods for control of end effectors
Techniques for controlling an end effector include a first engagement member coupled to a first actuator, a second engagement member coupled to a second actuator; and a control unit. The control unit is configured to engage the first engagement member with a third engagement member of an instrument, where movement of the third engagement member causes a movement of a degree of freedom (DOF) of an end effector in a first direction; engage the second engagement member with a fourth engagement member of the instrument, where movement of the fourth engagement member causes a movement of the DOF in a second direction opposite the first direction; actuate the DOF in the first direction to a first detectable position; actuate the DOF in the second direction to a second detectable position; and actuate the DOF to a third position between the first and second detectable positions.
System and user interface for displaying actual operating parameters and ideal operating parameters
A surgical system and a computing device for a surgical system that is configured to calculate actual operating parameters of an electrosurgical instrument, including an actual angle between the jaw members of the electrosurgical instrument, and to display a user interface. The user interface includes an ideal angle range between the jaw members and the actual angle between the jaw members of the electrosurgical instrument relative to the ideal angle range. The computing device is further configured to determine if the actual angle between the jaw members of the electrosurgical instrument is outside the ideal angle range.
System and method for surgical tool insertion using multiaxis force and moment feedback
Devices, systems, and methods for detecting unexpected movement of a surgical instrument during a robot-assisted surgical procedure are provided. The surgical robot system may be configured to measure forces and torques experienced by the surgical instrument during the surgical procedure and determine if the forces and torques are within an acceptable range. The robot system is further configured to notify the user of the presence of the unexpected movement.
SYSTEMS AND METHODS FOR INSTRUMENT ENGAGEMENT
A method of engaging a medical instrument with a medical instrument manipulator comprises receiving an indication that a first input coupling of the medical instrument is positioned adjacent to a first drive output of the manipulator. The first drive output is driven by a first actuating element. In response to receiving the indication, the first drive output is rotated in a first rotational direction. A determination is made, by one or more processors, as to whether a resistance torque is experienced by the first actuating element after rotating the first drive output in the first rotational direction. If the resistance torque is not experienced by the first actuating element after rotating of the first drive output in the first rotational direction, the first drive output is rotated in a second rotational direction. A determination is made, by the one or more processors, as to whether a resistance torque is experienced by the first actuating element after rotating of the first drive output in the second rotational direction.
PATIENT-SPECIFIC SURGICAL METHOD AND SYSTEM
A method of determining patient-specific implant parameters for an implant used in a surgical procedure is described. A surgical system receives one or more initial transfer functions and one or more preoperative input factors for a patient and generates a surgical plan comprising one or more patient-specific implant parameters based on the one or more initial transfer functions and the one or more preoperative input factors for the patient. The surgical system further receives one or more intraoperative input factors for the patient and updates the one or more patient-specific implant parameters based on the one or more intraoperative input factors for the patient. An implant for the patient is selected based on the one or more updated patient-specific implant parameters.
SENSING DEVICE AND CONTROL SYSTEM INCLUDING THE SAME
A sensing device includes a housing including a first side wall member arranged in an up-down direction with respect to a bottom surface; a first handle formed in a closed curve shape, at least a portion of which is exposed to an outside of the housing and placed on a predetermined first surface, and coupled to one side of the first side wall member so as to be capable of orbital movement along an extension direction of the closed curve at a predetermined location on the closed curve; a first rotating body rotating around a predetermined first rotation axis in conjunction with the orbital movement of the first handle; a support member coupled to the housing, and supporting the first handle such that the first handle maintains a fixed position at the predetermined location; and a first sensor sensing information on a rotational movement of the first rotating body.
Medical instrument having a ball bearing or sliding bearing as a generator
A medical, motor-operated or hand-operated or operable instrument includes a number of bearings for supporting a shaft for applying torque to a tool, of which bearings at least two selected or selectable bearings form a bearing pair. A distance sleeve axially spaces apart the bearings of the bearing pair. The instrument includes a component located at least partly radially inside the distance sleeve. The component is or can be rotationally coupled to at least one of the two bearings to rotate together with a rotating part of the at least one of the two bearings, or to form a rotating part of the at least one of the two bearings. At least one permanent magnet is fastened or formed on or in the component. A coil is arranged on or in the distance sleeve.
Adjustable implant, system and methods
Aspects of the disclosure relate to an adjustable implant configured to be implanted into a patient that includes an adjustable portion moveable relative to a housing. The adjustable implant may include various smart components for enhancing operation of the implant. Smart components may include a controller for managing operations and a transducer for communicating ultrasound data with an external interface device. Additional smart components may include a load cell within the housing for measuring an imparted load; a sensor for measuring angular position of the adjustable portion; a dual sensor arrangement for measuring imparted forces; a reed switch; a half piezo transducer; and an energy harvester.
