    Abstract: A remote center manipulator for use in minimally invasive robotic surgery includes a base link held stationary relative to a patient, an instrument holder, and a linkage coupling the instrument holder to the base link. First and second links of the linkage are coupled to limit motion of the second link to rotation about a first axis intersecting a remote center of manipulation. A parallelogram linkage portion of the linkage pitches the instrument holder around a second axis that intersects the remote center of manipulation. The second axis is not coincident with the first axis. Third and fourth links of the linkage are coupled to limit motion of the fourth link to rotation about a third axis intersecting the remote center of manipulation. The third axis is not coincident with either of the first and second axes. Various combinations of hardware-constrained remote center of motion robotic manipulators with redundant mechanical degrees of freedom are disclosed.

    Abstract: A computer-assisted medical system includes robotic manipulators, a user input system operable to generate signals to control the manipulators, and a controller configured to execute instructions to perform operations. A portion of the user input system is movable relative to the plurality of manipulators. The operations include, in a pairing mode, associating a first manipulator of the plurality of manipulators with the portion of the user input system based on movement of the portion of the user input system relative to the first manipulator, and, in a following mode, controlling motion of the first manipulator in accordance with an indication generated by the user input system in response to operation of the portion of the user input system by a user.

    Abstract: A manipulator for a surgical instrument may comprise an instrument holder coupled with the surgical instrument and rotatable in a plane that passes through a remote center. The manipulator may also comprise a linkage assembly coupled to the instrument holder to limit motion of the instrument holder to rotation about an axis that intersects the remote center. The linkage assembly may comprise a first linkage arm comprising first and second pulleys. Each pulley may comprise first and second drive tracks which are substantially co-planar. The first linkage arm may also comprise a first drive member section extending between the first drive tracks of the pulleys and a second drive member section extending between the second drive tracks of the pulleys. The first drive member section may be wound around the first pulley in a first direction and the second drive member section may be wound around the first pulley in an opposite direction.
