Abstract
Featured is a closed loop surgical system including one or more control units that are configured to form a fluid control subsystem for fluid control and a device control subsystem for controlling a surgical device. The two control subsystems in combination provide an automatic self-managed closed loop system for the control of fluid into and out of the surgical site by means of intelligent communication and for maintaining a preselected pressure desired by the surgeon. In particular embodiments, this is accomplished by utilizing empirically correlated motor speed and load measurements, based on supplied current, from the surgical resection device when using its specific resection capability. For example, automatically adjusting fluid flow responsive to changes in loading of a surgical device or automatically sensing a load change for the surgical device during a surgical procedure and automatically changing (increasing or decreasing) fluid flow responsive to the load change.
