A Minimally Invasive Skin Biopsy for Conditions in the Epidermis
Skin conditions of the epidermis on the face and neck can result in long-term scarring when biopsied using the current standard of care (SOC). We designed a device that removes a skin sample of 4 x 4 mm and a depth of no more than 1mm while maintaining the integrity of the skin sample for pathologist diagnosis. Our design includes a handle and receiving tube that reduces the risk of injury to the dermatologist by inverting the direction of the cut from a pushing method to pulling. Our device reduces current SOC variability by giving the dermatologist more control over the trajectory of the blade. Safety and efficacy will be evaluated through cadaver testing.
