Anti-Clogging Fluid Management System
First Claim
1. A fluid management system, comprising:
- a housing havingan irrigation pump configured to couple to irrigation tubing for delivering fluid to a tissue site,an aspiration pump configured to couple to aspiration tubing for aspirating fluid from a tissue site,a coupling adjacent to the aspiration pump and having first and second pathways formed therein that are configured to seat a first tubing portion and a second tubing portion of an aspiration tubing coupled to the aspiration pump, anda valve assembly disposed on the housing and configured to selectively pinch closed tubing disposed within the first pathway and the second pathway, the valve assembly being 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.

Abstract
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.

7. A surgical method, comprising:
-
activating a fluid management device to deliver fluid through an irrigation tube to a tissue site and to aspirate fluid from the tissue site through a first aspiration tube; and activating a tool to cause a valve on the fluid management device to move from a first position, in which the first aspiration tube is open and a second aspiration tube is pinched closed, to a second position, in which the first aspiration tube is pinch closed and the second aspiration tube is open such that fluid is aspirated from the irrigation site through the second aspiration tube, the valve applying a force to the second aspiration tube to deform the second aspiration tube open when the valve moves from the first position to the second position. - View Dependent Claims (8, 9, 10)
