Abstract: Sensor-enabled surgical retractor devices, systems, and methods are disclosed herein that can be coupled to a surgical robot during a robotic or robot-assisted surgical procedure to maintain health of retracted anatomy and prolong the amount of time until a surgical procedure must be interrupted to adjust a retractor. In some embodiments, interruption of a surgical procedure can be avoided by providing for minor and, in some cases, automatically administered, adjustment of retractor devices to alleviate pressure on retracted tissue without requiring surgeon attention or intervention. Fine (e.g., minor) adjustments to the retractor can be made automatically over the course of a surgical procedure to prevent damage to retracted anatomy and increase the time until a major adjustment of the retractor is needed.
