Abstract
The debridement tip of the instant invention provides efficient cleaning action and is capable of handling excessive amounts of debris. It also is able to track irregular debridement sites such as canals and gutter wounds. It furthermore visually indicates when it is clogged. The debridement tip comprises an inner cannula and an outer cannula. The outer cannula is flexible so that it tracks the debridement site. The outer cannula surrounds the inner cannula and forms an enlarged collection chamber near a proximal end of the debridement tip for collecting debris. The collection chamber is easily opened to allow removal of the debris. The collection chamber is also flexible so that if the tip becomes clogged either the outer cannula or the collection chamber or both will collapse thus visually indicating the clogged condition. A filter at one end of the collection chamber prevents large debris from leaving the chamber. The filter is shaped to resist clogging. A suction chamber behind the filter ensures suction across the full diameter of the filter to further resist clogging. The distal end of the outer cannula is collapsible to a smaller diameter so that it can extend into narrow passages.
