    摘要: A robotic control method for a camera (30) having an optical view and a robot (40) having an end-effector (42) and one or more joints (41) for maneuvering end-effector (42). The robotic control method involves an acquisition of a digital video frame (32) illustrating an image as optically viewed by the camera (30), and an execution of a visual servoing for controlling a pose of end-effector (42) relative to an image feature within the digital video frame (32). The visual servoing involves an identification of a tracking vector (vtrk) within an image coordinate system (80) of the digital video frame (32) extending from a tracking point (TR) to a target point (TG) associated with the image feature, a mapping of the tracking vector within a configuration space (100) constructed from a robotic coordinate system (90) associated with the end-effector (42), and a derivation of a pose of the end-effector (42) within the robotic coordinate system (90) from the mapping of the tracking vector (vtrk) within the configuration space (100).

    摘要: An active cannula (10) can include a plurality of hollow tubes (100, 110, 120), a plurality of blocks (200, 210, 220), and a track (1800). Each of the blocks can be connected to one of the hollow tubes. Each of the blocks can be operably connected to the track for movement therealong. In a first position, the blocks can be separate from each other along the track and the plurality of hollow tubes can be nested. In a second position, the blocks can be adjacent to each other along the track and the plurality of hollow tubes can be extended. In the second position, the plurality of hollow tubes can provide access to the targeted anatomical region from outside of the body. Other embodiments are disclosed.
