    摘要: A surgical system includes a preload assembly in a surgical instrument surgical instrument manipulator that is under the control of a controller. The controller can automatically cause the preload assembly to engage and disengage a preload. A surgical apparatus includes a surgical instrument manipulator assembly and a sterile adapter assembly. The sterile adapter assembly is mounted in the distal face of the surgical instrument manipulator assembly. When the preload assembly configures the surgical instrument manipulator assembly to apply a preload force on the sterile adapter assembly, the sterile adapter assembly is removable from the distal face of the surgical instrument manipulator. The sterile adapter assembly includes a mechanical sterile adapter assembly removal lockout and a mechanical surgical instrument removal lockout.

    摘要: A surgical system (200) includes a surgical instrument (260) that is sensitive to backlash that would adversely affect the transmission of controlled torque and position to the surgical instrument. The surgical instrument (260) is coupled to motors in a surgical instrument manipulator assembly (240) via a mechanical interface. The combination of the mechanical interface and surgical instrument manipulator assembly (240) have low backlash, e.g., less than 0.7 degrees. The backlash is controlled in the surgical instrument manipulator assembly (240). From the drive output disk (545) in the surgical instrument manipulator assembly to the driven disk (964) of the surgical instrument, the mechanical interface has zero backlash for torque levels used in surgical procedures.

    摘要: In one embodiment of the invention, a robotic arm is provided including a linkage assembly and a strap drive train. The linkage assembly includes first, second, third, and fourth links pivotally coupled in series together at first, second, and third joints to define a parallelogram with an insertion axis. The strap drive train includes first and second sets of straps coupled to the linkage assembly. As the linkage assembly is moved about a pitch axis, the first set of straps ensures the third link maintains the same angle relative to the first link, and the first and second set of straps ensures the fourth link maintains the same angle relative to the second link.
