发明名称 VARIABLE INSTRUMENT PRELOAD MECHANISM CONTROLLER
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.

主权项 1. An apparatus comprising: a preload track; and a preload assembly configured to ride on the preload track, and the preload assembly configured to couple to a surgical device assembly, wherein if the preload assembly is positioned at a first location on the preload track, the preload assembly is configured to apply a force proportional to a first force to the surgical device assembly, andwherein if the preload assembly is positioned at a second location on the preload track, the preload assembly is configured to apply a force proportional to a second force to the surgical device assembly, andwherein the second force is larger than the first force.
