  • Publication number: 20210386494
    Abstract: A teleoperational system receives a movement command in response to movement of an input device, in response to determining an instrument is being controlled based on the movement of the input device, maps the movement command to a first movement of the instrument in an instrument frame using a first mapping, and in response to determining a tissue probe is being controlled based on the movement of the input device, maps the movement command to a second movement of the tissue probe in a tissue probe frame using a second mapping. The first mapping maps motion in an input direction in the input frame to an instrument direction in the instrument frame. The second mapping maps motion in the input direction to a tissue probe direction in the tissue probe frame. The instrument direction corresponding with the input direction. The tissue probe direction not corresponding with the input direction.

  • Patent number: 11129683
    Abstract: A teleoperational medical system comprises an input device and a manipulator configured to couple with and move an instrument. The system also comprises a control system including one or more processors. In response to a determination that the instrument is inserted into an instrument workspace in a corresponding direction to a field of view of the workspace, the control system is configured to map movement of the input device to movement of the instrument according to a first mapping. In response to a determination that the instrument is inserted into the instrument workspace in a non-corresponding direction to the field of view, the control system is configured to map movement of the input device to movement of the instrument according to a second mapping. The second mapping includes an inversion of the first mapping for at least one direction of motion of the instrument.

  • Patent number: 9999472
    Abstract: End effectors with closing mechanisms, and related tools and methods may be particularly beneficial when used for minimally invasive surgery. An example surgical tool comprises a first and second jaw movable between a closed grasped or clamped configuration and an open configuration. The tool further comprises a soft grip mode for grasping the tissue at a first force during which a separation parameter between the jaws is measured, and a therapeutic clamping mode in which the jaws clamp on the body tissue at a force greater than the grasping force. The methods comprise grasping the body tissue between jaw members, measuring the separation parameter between jaws, indicating on a user interface the separation parameter for comparison to a desired separation parameter, and then releasing the body tissue for repositioning or therapeutically clamping the body tissue in response to the separation parameter indication.
