Abstract: A robot-assisted surgical system includes a robotic manipulator for robotic positioning of a surgical instrument, and a user input device moveable by a user to cause the robotic manipulator to move the surgical instrument. The system is configured to define virtual boundaries in a workspace of the user input device, based on range limits or user ergonomic limits of the user input device. The system alerts the user if the user input device is moved into proximity of the virtual boundary. This cues the user that it would be useful to clutch and reposition the user input device.

Abstract: A robotic surgical system includes a hydraulic drive system and a surgical instrument removably positioned in operative engagement with the hydraulic drive system.

Abstract: A robotic surgical system in which the system applies a scaling factor between user input from a user input device and corresponding movements of the robotic manipulator. Scaling factors may be applied or adjusted based on detected conditions such as the type of instrument being manipulated, detected distance between multiple instruments being manipulated, user biometric parameters.

Abstract: A robotic surgical system includes a hydraulic drive system and a surgical instrument removably positioned in operative engagement with the hydraulic drive system.

Abstract: A method of controlling a robotic arm in a surgical system comprises manually applying a force to a body of the robotic arm. Force information is received from a gesture force sensor on the robotic arm and a controller determines, using the force information, whether the force is a gesture force input. If the force is determined to be a gesture force input, the controller initiates a predetermined system function. The predetermined system function may be a change in operational state, movement between operational modes, or a movement from a first configuration of the arm's joints to a second, predetermined, configuration of the arms joints.

Abstract: A minimally invasive medical system comprises a manipulator having a plurality of joints, each of the plurality of joints including a torque and/or force sensor. The manipulator includes an effector configured to receive a surgical instrument. The system comprises a programmable computing device programmed for moving the surgical instrument while estimating surgical forces applied to the patient by the surgical instrument using torque and/or force measurements from the plurality of torque and/or force sensors located at the joints.

Abstract: A robotic surgical system includes a fluid drive system and a surgical instrument removably positioned in operative engagement with the drive system. A sterile barrier covers non-sterile portions of the surgical system. Features of the sterile barrier are used to transfer motion output from the fluid drive system to the instrument for actuation of the instrument.
