Debridement extension providing irrigation and mechanical scrubbing for removal of dead, devitalized, or contaminated tissue from a wound

Abstract

A debridement extension including a proximal end and a distal end, with the proximal end being adapted for connection to both an irrigation source and a suction source. The debridement extension includes a fitting adjacent the proximal end which includes both an irrigation port and a suction port. An inner cannula and an outer cannula are both attached to the fitting of the debridement extension and are, respectively, in fluid communication with the irrigation port and the suction port. A debridement tip is affixed to the distal end of the debridement extension and is independently in fluid communication with both the irrigation path and the suction path formed by the inner and outer cannulas, respectively. The debridement tip includes a plurality of irrigation apertures in fluid communication with the irrigation path and spaced about the periphery of the irrigation tip as well as a plurality of suction apertures in fluid communication with the suction path and spaced about the periphery of the debridement tip. The inner and outer cannulas of the debridement extension are flexible so that the debridement extension can be readily inserted into a tract wound for debridement thereof. The debridement tip further includes a plurality of external longitudinal flutes.
