ADSON EXTRACTING FORCEPS HORIZONTAL SERRATED

Follicular unit graft extraction and implantation in hair transplant surgery

Adson Extracting Forceps Horizontal Serrated is a tissue forceps and graft-handling forceps of the Adson pattern, manufactured by BusinessMed Instruments®, for use in Hair Transplant Surgery (FUE / FUT), Plastic & Reconstructive Surgery, and Dermatology (Dermatologic Surgery).

Adson Extracting Forceps Horizontal Serrated grasps the follicular unit — a naturally occurring bundle of 1–4 terminal hairs with associated sebaceous glands, arrector pili muscle, and perifollicular connective tissue — at the epidermal collar of the occipital donor scalp, and seats the follicular unit graft into the recipient site slit in alopecic scalp dermis across the FUE graft extraction phase, FUE graft implantation phase, and FUT graft implantation phase.

Longitudinal Serration Jaw Grip and Axial Graft Retention

Fine flat platform tips carry longitudinal horizontal serrations running along the platform tip length — oriented parallel to the instrument axis, lengthwise along the jaw face. This serration geometry creates contact ridges that run in the direction of graft travel during recipient site insertion. The lengthwise orientation resists axial slippage of the follicular unit along the jaw face at the moment of slit entry — the primary slippage mode in techniques where the graft must travel a defined depth before seating — without requiring increased digital closure pressure to maintain grip. Cross-serrated tips resist lateral displacement; longitudinal serrations resist axial displacement: these are mechanically distinct grip geometries, and instrument selection follows the surgeon’s dominant slippage mode in their technique. Spring-action thumb forceps returns the jaws to the open position on release of digital pressure for continuous single-handed graft cycling.

Perifollicular Dermal Tissue Response and Graft Viability

The published acceptable clinical threshold for FUE is ≤5% graft transection rate. The hair follicle bulb — the dermal papilla — is the anatomical structure at risk when forceps grip at bulb depth or premature traction before punch release of subcutaneous follicular attachments produces a transected, non-viable graft that reduces yield and fails to grow post-implantation. Longitudinal serrations preserve the flat platform contact surface that avoids penetrating the epidermal collar while providing the surgeon axial graft retention through the insertion stroke into pre-made recipient site slits of defined depth and direction.

Technical Specifications

Clinical Uses and Applications

• The follicular unit epidermal collar is engaged at the occipital donor scalp during FUE graft extraction; longitudinal serrations resist axial graft displacement along the jaw face without increased digital closure pressure.
• Follicular unit grafts are advanced into recipient site slits in alopecic scalp dermis during the FUE graft implantation phase, with the lengthwise serration geometry retaining graft position axially through the insertion stroke depth.
• Strip-harvested follicular unit grafts are placed into recipient site slits during the FUT graft implantation phase — single-hair units to the hairline zone, multi-hair units to the mid-scalp and crown.
• Graft axial migration along the jaw face is the dominant slippage mode in deeper slit geometries; the horizontal serrated variant addresses this mode where cross-serrated tips do not.
• The follicular unit is delivered into the pre-made recipient site slit at correct angle and depth to prevent graft burial and popping of adjacent units.
• Follicular unit grafts are handled and sorted during the FUT strip harvesting preparation phase to maintain viability before implantation.
• Hair restoration procedures in Dermatologic Surgery use this forceps to place follicular unit grafts into recipient site slits at the alopecic scalp dermis.
