Patent number: 12220190Abstract: A surgical system includes a surgical instrument that is sensitive to backlash that would adversely affect the transmission of controlled torque and position to the surgical instrument. The surgical instrument is coupled to motors in a surgical instrument manipulator assembly via a mechanical interface. The combination of the mechanical interface and surgical instrument manipulator assembly have low backlash, e.g., less than 0.7 degrees. The backlash is controlled in the surgical instrument manipulator assembly. From the drive output disk in the surgical instrument manipulator assembly to the driven disk of the surgical instrument, the mechanical interface has zero backlash for torque levels used in surgical procedures.Type: GrantFiled: September 7, 2023Date of Patent: February 11, 2025Assignee: Intuitive Surgical Operations, Inc.Inventors: Thomas G. Cooper, Anthony K. McGrogan, Robert E. Holop, Todd R. Solomon, Eugene F. Duval, Kent M. Anderson

Patent number: 11523732Abstract: A compliant surgical device such as a flexible entry guide employs tendons to operate or steer the device and attaches asymmetric or constant force spring systems to control tension in the tendons. As a result, the surgical device can be compliant and respond to external forces during a surgical procedure without rapidly springing back or otherwise causing a reaction that damages tissue. The compliance also permits manual positioning or shaping of the device during or before insertion for a surgical procedure without damaging the tendons or connections of the tendons within the device or to a backend mechanism.Type: GrantFiled: August 30, 2018Date of Patent: December 13, 2022Assignee: Intuitive Surgical Operations, Inc.Inventors: Giuseppe M.
