An adjustable arm support for a surgical robotic system, the arm support comprising: a fixed armrest portion that is fixedly coupled to a console seat of the surgical robotic system; and an adjustable armrest portion that is adjustably coupled to the fixed armrest portion, the adjustable armrest portion

Surgical robotic systems, and methods of verifying functionality of a user interface device of such systems, are described. During a surgical procedure, the user interface device controls motion of a surgical tool. Proximity sensors of the user interface device generate proximity measures throughout the surgical procedure. The proximity measures are used to detect whether the user interface device is dropped and to responsively halt motion of the surgical tool. To verify an accuracy of the proximity sensors that provide the drop detection, a test is performed when the user interface device is placed in a dock. The test compares the generated proximity measures to expected proximity data. When the proximity measures match the expected proximity data, the system determines that the proximity sensors are functioning accurately and verifies that the user interface device is functioning safely. Other embodiments are described and claimed.

Disclosed are systems and methods for maintaining the opening force generated by robotic wrist jaws operating in position mode in which the jaws are commanded to a desired jaw angle prior to being commanded to generate a grip force. In the position mode, the desired jaw angle is above a threshold corresponding to an angle at which both jaws are just simultaneously in contact with an object held between the jaws or, if there is no object, when the jaws begin to touch each other. A feedback loop may analyze the desired jaw angle, the estimated jaw angle, and the measured opening force to determine if the jaws are in the position mode and if the measured opening force is below a minimum opening force threshold. If so, the feedback loop may calculate a jaw opening force error to maintain the jaw opening force above the minimum opening force threshold.

An apparatus for attaching a cannula to a robotic surgical system, the apparatus comprising: a first clamp component configured to transition between an open position and a closed position; a second clamp component spaced from the first clamp component, the first and second clamp components defining a region configured to receive a portion of the cannula and configured to retain the portion of the cannula in the region when the first clamp component is in the closed position; and a locking component configured to lock the first clamp component in the open position and allow the first clamp component to automatically transition to the closed position based on a position of the portion of the cannula within the region.

Disclosed is a console for operating an actuating mechanism, relating to the technical filed of automatic control, and being for use in resolving the technical problem of shift of a controller under the influence of gravity. The console for operating an actuating mechanism includes a controller and a support base. The controller is constrained in both the longitudinal direction and the vertical direction, so that connection between the controller and the support base is tight and reliable, and no displacement would occur in any of three directions (i.e., the longitudinal direction, the horizontal direction, and the vertical direction). Thus, the phenomenon that position information given by the controller is inaccurate due to shift of the controller under the influence of the gravity after long-term usage can be avoided, thereby removing the factors affecting success of surgery, and ensuring the success rate of the surgery.

A user console for a surgical robotic system has a seat having an armrest and an electromagnetic (EM) transmitter coupled to the armrest to generate an EM field in an EM tracking space around the armrest. A user input device having a handheld housing is to be positioned within the EM tracking by an operator who is seated in the seat, during a surgical procedure. Other aspects are also described and claimed.

An ear endoscope device for use in a surgical procedure in an ear includes a handle, a visualization shaft extending from the handle, a tool guide extending from the handle parallel to the visualization shaft and configured to guide a tool into the ear with the visualization shaft, an imaging sensor at a distal end of the visualization shaft, and a light source. In some embodiments, the ear endoscope is combined with a suction device. In other embodiments, it may be combined with another tool.

A method for intraoperatively measuring joint contact mechanics of a patient's joint is provided. The method includes inserting a sensor between first and second bones of a joint. Then a predetermined force is applied to one of the first and second bones. Afterwards, contact mechanics such as, contact stresses, contact areas and/or forces are measured between the first and second bones in response to the applied predetermined force.
