  • HAPTIC USER INTERFACE FOR ROBOTICALLY CONTROLLED SURGICAL INSTRUMENTS
    Publication number: 20230121745
    Abstract: A powered user interface for a robotic surgical system operates in accordance with a mode of operation in which the actuators are operated to permit motion of the handle in pitch and yaw motion constrained with respect to a virtual fulcrum in a work space of the user interface, and insertion motion is constrained along an axis passing through the virtual fulcrum. In a virtual fulcrum setting mode, a user is prompted to give input to the system selecting a desired point in space for the virtual fulcrum.

  • Haptic user interface for robotically controlled surgical instruments
    Patent number: 11547513
    Abstract: A powered user interface for a robotic surgical system includes a base, a handle mounted to the base and moveable relative to the base in at least six degrees of freedom, and actuators. The interface operates in accordance with a first mode of operation in which the actuators are operated to constrain predetermined ones of the joints to permit motion of the handle in only 4DOF with respect to the base, and a second mode of operation in which the actuators permit motion of the handle in at least 6DOF with respect to the base.

  • Haptic user interface for robotically controlled surgical instruments
    Patent number: 11540890
    Abstract: A powered user interface for a robotic surgical system having a manipulator and a surgical instrument mounted to the manipulator includes a base and a linkage assembly that includes two two-bar linkage mechanisms. The linkage assembly is rotatably mounted to the base at a base joint, and a handle mounted to each of the two-bar linkage mechanisms. Sensors and actuators are arranged to measure and actuate the position and orientation of the user interface.

  • OPEN SOURCE ROBOTIC PLATFORM
    Publication number: 20220104890
    Abstract: An open platform surgical robotic system for use in manipulating and actuating a surgical hand instrument of the type having a handle configured to be grasped by a human hand and actuation members of elements configured to be operated by fingers of a human hand. The system includes a robotic arm including an end effector having a gripper comprising a plurality of digits. The digits are configured to receive the handle of the manual surgical instrument and operate the actuation members.
