摘要： A robotic imaging apparatus is disclosed. A robotic imaging apparatus includes a robotic arm, a stereoscopic camera, and a sensor positioned between the robotic arm and the stereoscopic camera. The sensor transmits output data that is indicative of translational and/or rotational force imparted on the stereoscopic camera by an operator. The robotic imaging apparatus also includes a processor that is configured to determine a movement sequence for the robotic arm based on a current position of the robotic arm and the output data from the sensor and to cause at least one of the joints of the robotic arm to rotate based on the determined movement sequence via one or more motor control signals provided to the at least one joint. The rotation of the at least one joint provides power-assisted movement of the robotic arm based on the detected translational and/or rotational forces imparted by the operator.

摘要： A stereoscopic visualization camera and platform are disclosed. An example stereoscopic visualization camera includes a main objective assembly and left and right lens sets defining respective parallel left and right optical paths from light that is received from the main objective assembly of a target surgical site. Each of the left and right lens sets includes a front lens, first and second zoom lenses configured to be movable along the optical path, and a lens barrel configured to receive the light from the second zoom lens. The example stereoscopic visualization camera also includes left and right image sensors configured to convert the light after passing through the lens barrel into image data that is indicative of the received light. The example stereoscopic visualization camera further includes a processor configured to convert the image data into stereoscopic video signals or video data for display on a display monitor.
