Surgical Forceps, Sorted — Thumb, Tissue, Hemostatic, and How to Tell the Classic Patterns Apart

Every surgical instrument catalog lists hundreds of forceps, but they resolve into a few families once you know what to look for: how they close, what the jaws carry, and whether they lock. This is the identification guide I wish someone had handed me in my first instrument room.

The two mechanical families

Thumb forceps are tweezers: two blades joined at one end, closed by finger pressure, open the moment you relax. Ring (locking) forceps are scissor-shaped, with finger rings and a ratchet between the handles that holds the jaws closed by themselves. Everything else is variation.

Thumb forceps worth knowing

• Adson — short, with a narrow waist and fine tip; the skin-closure forceps. Toothed versions grip the dermis without crushing.
• DeBakey — long atraumatic pattern with a distinctive double row of fine ribs; built for vessels and delicate tissue. The name is shorthand for “don’t bruise anything.”
• Rat-tooth patterns — interlocking teeth for tough tissue like fascia. Never for bowel or vessels.
• Dressing forceps — smooth serrated jaws, no teeth; for packing and dressings rather than living tissue.

Hemostatic forceps: the ratcheted clamps

• Kelly and Crile — the mid-size workhorses, both with transverse serrations. The classic distinction: Crile’s serrations run the full jaw; Kelly’s stop partway. Both clamp bleeding vessels before ligation.
• Mosquito (Halsted) — the smallest pattern, for fine vessels.
• Kocher — serrated jaws plus interlocking teeth at the tip; a firm grip that is by design traumatic. Fascia, not vessels.

Sponge, towel, and specialty patterns

Sponge (Foerster) forceps carry a folded gauze on ringed, often smooth jaws. Towel clamps (Backhaus) pierce and pin drapes. Beyond these lie the specialty trees — obstetric, ENT, orthopedic — each a variation on grip, reach, and how much trauma the target tissue tolerates.

Care is part of identification

Box-lock joints trap debris; instruments are inspected open, cleaned open, and autoclaved open. A forcep whose ratchet no longer holds under a light squeeze is out of service, whatever its name.
