Keyes Dermal Punch 3mm, 10cm

Clinical Application

Designed for targeted cutaneous tissue sampling and small-lesion excision, this 3 mm dermal punch is sized for diagnostic punch biopsies of papules, nodules, and suspicious lesions where a full-thickness core is required for histopathology. The 3 mm diameter provides an appropriate balance between diagnostic yield and cosmetic outcome, commonly used when primary closure is unnecessary or when a single interrupted suture may be used for closure. Typical users include dermatologists, plastic surgeons, general surgeons, and clinic proceduralists performing in-office biopsies or minor excisions.

Design & Configuration

The instrument features a circular cutting edge that cores a cylindrical tissue sample with a single rotational motion. The 10 cm shaft length provides tactile control and reach for perpendicular entry into the skin and for controlled depth guidance. The compact 3 mm cutting diameter minimizes surrounding tissue trauma and facilitates rapid hemostasis and wound management. The handheld, manually operated design allows direct feedback to the operator for depth and resistance during the punch technique.
