Keyes Trephine

Description

Keyes Trephine

The Keyes trephine is a hand-held punch with a sharp circular edge. A gentle twisting push cuts a round core of skin for biopsy or excision.

Seven diameters

We stock 2, 3, 4, 5, 6, 7 and 8 mm. In addition, small punches take a sample with a tiny wound. Meanwhile, the larger sizes remove a whole small lesion in one pass.

Why a reusable Keyes trephine

A steel punch can be resharpened and sterilised many times. So the cost per biopsy stays low. In addition, the solid handle gives steady control during the twist.

Technique

Stretch the skin across the line of least tension. Then press and rotate the punch until it drops through the dermis. Finally, lift the core with fine forceps and cut its base.

Who uses it

Dermatologists, GPs and plastic surgeons keep a set. Besides, it suits clinic and theatre work alike. Moreover, many choose three or four sizes to cover common lesions.

Edge care

Rinse the punch straight after use. Clean inside the barrel with a small brush, then dry. Store it with a cap on the cutting edge.
