Goulian / Weck Dermatome

The Goulian dermatome — also called the Weck-Goulian or simply Weck blade — is a small handheld dermatome for harvesting limited-area, fine split-thickness grafts. The blade is mounted in a short handle with a calibrated depth guard, producing grafts of uniform thickness over a narrow width.

Design​

  • Disposable blade (Weck brand) with integrated depth-setting guard
  • Short handle for precise hand control
  • Fixed width (~1–3 cm) — suitable only for small grafts
  • Depth settings (0.008"–0.015") built into the blade design

Key Uses​

  • Small-area STSG harvest for discrete defects
  • Urethral reconstruction grafts — historically used for small quilted grafts before buccal mucosa became the dominant urethral graft
  • Penile-shaft resurfacing after limited-area excision
  • Coverage of small hidradenitis excision wounds
  • Teaching and learning — simpler than powered dermatomes

Advantages​

  • Simple, cheap, portable
  • No power or gas supply needed
  • Consistent thickness (once technique is learned) thanks to the integrated depth guard
  • Minimal setup

Limitations​

  • Width limit — large grafts require many passes or a powered dermatome
  • Technique-dependent — draw speed and angle still affect quality
  • Surgeon-specific — some surgeons never adapt to the Weck feel
