The disclosed embodiments include tools for aiding a user in debriding necrotic tissue. For example, in one embodiment, a debridement tool is disclosed that includes a housing having an interior space. A motor and a power source are disposed within the interior space of the housing. The power source is operable to provide power to the motor. A blade is coupled to a first end of the housing. The blade is operable to vibrate when the motor is powered. The debridement tool further includes a lighting element disposed within the housing and beneath a cutting edge of the blade. The lighting element is operable to illuminate the tissue site. In some embodiments, the lighting element operates at a particular wavelength that assists in distinguishing between necrotic tissue and healthy tissue.
