Various methods and devices for performing arthroscopic surgery are provided. In particular, methods and devices are provided for reshaping, unclogging, and vibrating tubing of an aspiration pump in a fluid management system. For example, a fluid management system is provided that includes a valve assembly disposed on a housing and configured to selectively pinch closed tubing disposed within a first pathway and a second pathway. The valve assembly is configured to bias tubing disposed within the first and second pathways to an open position after the tubing is pinched closed by the valve assembly. As another example, a fluid management system is provided that includes a vibratory mechanism coupled to a valve and configured to vibrate the valve so as to facilitate the flow of debris through tubing disposed within first and second tubing pathways.
