A compound curette for removing tissue samples and delivering liquid and anti-pathogen to the treated area includes a hollow handle that fits a reservoir with a medicated or cosmeceutical solution. A solution is delivered from the reservoir through a channel to a scraping end of the curette by a button activated mechanism. The scraping end of the curette is made of a metal or hard plastic and is covered in anti-pathogen material. The liquid delivery allows placing a medicine or sterilizing solution directly at the locust of the infection. Pathogen inhibition coating provides for a good safeguard to stop or slow bacteria or fungus proliferation. The method of scraping debris and medication delivery is particularly useful for the treatment of onychomycosis, commonly referred to as a fungus infection of the toenail. Main portions of the curette could be detachable, allowing for the easy reservoir replacement and for the use of multiple scraping utensils. Similarly, the device could be manufactured for a single use when all parts are molded together.
