    Abstract: A method for providing a visual indication regarding a state of an instrument comprises sensing usage information about the instrument and using a motor to rotate an indicator body from a first position to a second position in response to sensing the usage information meets a predetermined condition. The method further comprises holding the indicator body in the first position or the second position, respectively. In the first position a first portion of the indicator body is visible on an exterior of the instrument and in the second position a second portion is visible. In the first position, the first portion of the indicator body provides a visual indication that the usage information of the instrument does not meet the predetermined condition, and in the second position the second portion of the visual indicator body provides a visual indication that the usage information of the instrument meets the predetermined condition.

    Abstract: A medical instrument includes cable pairs respectively wound around input spindles and connected to actuate degrees of freedom of an instrument shaft structure. The cables may connect so that rotating the input spindles actuates corresponding degrees of freedom. First pulleys in the instrument may receive first cables from the input spindles and redirect the first cables toward the instrument shaft, and second pulleys may receive second cables from the input spindles and redirect the second cables toward the instrument shaft. In one configuration, the first and second pulleys are respectively mounted at first and second levels, and the second pulleys redirect the second cables through the first level. Additionally or alternatively, one level of cables may cross while the other level of cables does not.

    Abstract: An actuation mechanism for a medical instrument includes a pinion and a face gear that move a push-pull element. The pinion has a mounting that permits rotation of the pinion by an external control system such as a robot. The face gear meshes with the pinion. The push-pull element may have a proximal end coupled to the face gear and a distal end coupled to a tool at a distal end of an instrument shaft. A manipulator coupled for manual rotation of the actuation mechanism may include a slip clutch to prevent manual application of excessive force to the actuation mechanism.
