Negative Pressure Tissue Debridement Devices, Systems, and Methods

摘要

In some embodiments, a debridement tool may include a housing, a reduced-pressure lumen, a debridement head, an impeller, and a drive system. The debridement head may be moveable relative to the housing. The impeller may be positioned in fluid communication with the reduced-pressure lumen and be moveable relative to the housing by operation of reduced pressure being applied to the impeller. The drive system may be coupled between the impeller and the debridement head and be configured to impart movement from the impeller to the debridement head.
