Keyes Dermal Punch 7mm, 10cm

Clinical Application

This dermatologic punch is designed to obtain full-thickness skin cores and perform circular excisions of small lesions. The 7 mm cutting diameter is commonly used for diagnostic punch biopsies that require adequate tissue for histopathology, removal of benign epidermal/dermal lesions, and harvesting small round grafts (for example in hair transplantation). The instrument enables precise, controlled circular cuts with minimal peripheral tissue trauma and facilitates specimen transfer to pathology containers.

Design & Configuration

The instrument features a sharp, cylindrically ground cutting edge that cores tissue as it is rotated and advanced. The hollow core design captures the specimen within the barrel for secure retrieval and reduces fragmentation. The 10 cm overall length provides a balanced working profile for hand control and visibility during office and minor-procedure settings. The straight shaft geometry supports perpendicular approach to the skin surface, which helps produce uniform, reproducible specimens suitable for histologic evaluation and cosmetic closure.
