Hemostatic forceps — Mosquito, Crile, Kelly & when to use each
Mosquito, Crile, Kelly, Allis, Adson, Backhaus — six families of hemostatic forceps cover everything from delicate vessel control to towel clipping. Here's how to tell them apart and pick the right one.
Hemostatic forceps are the workhorse of any oral surgery tray. They control bleeding, hold tissue, clamp vessels, secure drapes and grip needles in a pinch. ErgoDenta carries 31 hemostatic forceps spanning the Mosquito (Halsted), Crile, Kelly, Allis, Adson and Backhaus families — straight and curved, in lengths from 12 to 18 cm.
The six hemostatic forceps families
- Mosquito (Halsted-Mosquito) — the smallest and finest. 12 cm, very fine jaws. Used for delicate vessel hemostasis in oral surgery, periodontal flaps and microsurgery.
- Crile — slightly larger than Mosquito (14 cm). Heavier jaws with horizontal serrations. The general-purpose oral surgery hemostat for vessel control and tissue grasping.
- Kelly — similar size to Crile but with serrations only on the distal half of the jaw. Used where the operator wants part of the jaw to grasp without crushing.
- Allis (Allis Tissue Forceps) — toothed jaws designed to grasp and hold soft tissue without crushing. Used for retracting flaps, holding mucosal edges and anchoring drapes.
- Adson — fine-tipped tissue forceps without ratchet locking. Used for delicate handling of mucosal edges, gingival biopsies and microsurgical tissue work.
- Backhaus (Towel Clip) — sharp-pointed jaws designed to clip surgical drapes to the patient or each other. Sharp variant pierces the drape; non-sharp engages it.
Straight vs curved — when each wins
Most hemostatic families come in both straight and curved variants. The choice depends on access angle:
- Straight — best for working in line with the operator's wrist, surface access, and direct vessel control.
- Curved — best for working around tissue corners, posterior access, and clamping vessels at angles where straight jaws can't reach.
For oral surgery specifically, curved versions tend to dominate because intraoral access angles rarely line up with the operator's wrist. Most surgical kits stock both — at minimum a curved Crile and a curved Mosquito.
Chapter 3ErgoDenta's hemostatic kit
The 31-piece ErgoDenta range covers all six families in clinically relevant sizes:
- Mosquito — Halsted-Mosquito 12 cm, straight + curved (Fig. 3406, 3407)
- Crile — 14 cm, straight + curved (Fig. 3454)
- Allis — Allis Tissue Forceps, straight (Fig. 3432)
- Adson — Adson Forceps, straight + curved (Fig. 3461, 3462)
- Backhaus — Sharp variant for towel clipping (Fig. 3470, 3471)
All built from surgical-grade stainless steel, fully autoclavable, with ratchet locking on the Mosquito, Crile, Kelly and Allis variants.
Chapter 4Which hemostat for which task — quick rule
- Bleeding from a small intraoral vessel — curved Mosquito (Halsted), then suture or cauterise.
- General oral surgery hemostasis — curved Crile, the everyday workhorse.
- Holding a flap during periodontal surgery — Allis tissue forceps with toothed jaws.
- Manipulating gingival edges during a biopsy or periodontal microsurgery — Adson with fine tip.
- Securing surgical drapes — Backhaus sharp variant.
- Holding suture material while tying — Mosquito or Crile, whichever is closest.
Care & maintenance
- Lubricate the joint after every cycle — instrument oil at the hinge prevents stiffness and squeaking.
- Test the ratchet before sterilisation — should click crisply through 3–4 positions and hold under jaw closure.
- Inspect the jaw alignment — close the jaws and hold up to light. No light should pass between the closed tips.
- Sharpen the Allis teeth if they round off — the toothed jaw is what makes Allis hold tissue without crushing; rounded teeth slip.
- Replace when the ratchet no longer holds, the joint is permanently stiff, or the jaw alignment cannot be restored.
Six hemostatic forceps families — at a glance
| Family | Length | Jaw geometry | Primary use |
|---|---|---|---|
| Halsted-Mosquito | 12 cm | Very fine, full serration | Small vessel hemostasis, microsurgery |

| Kelly | 14 cm | Distal-half serration | Tissue grasping with partial crush |
| Allis | 15 cm | Toothed jaws | Hold tissue without crushing |
| Adson | 12 cm | Fine tip, no ratchet | Delicate tissue manipulation, biopsy |

What's the difference between Mosquito and Crile forceps?
Mosquito (Halsted-Mosquito) forceps are 12 cm with very fine jaws designed for small vessel hemostasis and microsurgery. Crile forceps are 14 cm with standard heavier jaws — the general-purpose oral surgery hemostat. Most surgical kits stock both: Mosquito for delicate work, Crile for routine vessel control.
When do I need Allis tissue forceps?
Allis forceps have toothed jaws designed to grasp and hold soft tissue without crushing it. Use them when you need to retract a periodontal flap during surgery, hold mucosal edges during suturing, or anchor drapes. They're not interchangeable with Crile or Mosquito — the toothed jaw is the key feature.
Should hemostats be straight or curved for oral surgery?
Curved variants tend to dominate in oral surgery because intraoral access angles rarely line up with the operator's wrist. Straight variants are useful for surface work and when working in line with the wrist. Most kits stock both: a curved Mosquito and a curved Crile at minimum.
What's the difference between Adson and Adson-Brown forceps?
Adson forceps have fine tips with smooth or lightly serrated jaws and no ratchet — used for delicate handling of mucosal edges. Adson-Brown forceps have small teeth at the tip designed to grip tissue more firmly. ErgoDenta carries the standard Adson; Brown variants are typically distinguished by the toothed tip in the catalogue description.
What are Backhaus forceps used for in dentistry?
Backhaus forceps (also called towel clips) have sharp-pointed jaws designed to clip surgical drapes to the patient or to each other during oral surgery. The sharp variant pierces the drape; the non-sharp variant grips it without piercing. Essential for any sterile-field surgical setup.
How do I test if a hemostat ratchet is still good?
Close the jaws slowly. The ratchet should click crisply through 3–4 distinct positions. At each position, the jaws should hold their closure under finger pressure on the handles. If the ratchet skips, slips or fails to hold, the instrument needs servicing or replacement before the next use.
Are hemostats also used for holding sutures?
Yes — Mosquito and Crile forceps are commonly used to hold the free end of suture material while tying knots, especially in deep wounds where finger access is limited. Dedicated needle holders (Mathieu, Mayo-Hegar) are the proper tool for grasping the needle itself, but hemostats are perfectly acceptable for managing the suture tail.
How do I clean dried blood from the jaw serrations?
Soak in enzymatic detergent for 10–15 minutes, then ultrasonic clean for at least 5 minutes with the jaws open. Inspect the serrations under magnification — any residue trapped in the serration grooves needs to be removed before sterilisation, or it will be baked on permanently.
What's the difference between Backhaus 'sharp' and standard variants?
Sharp Backhaus forceps have pointed jaws designed to pierce surgical drape material — the points lock the drape to the underlying tissue or to another drape. Standard (non-sharp) Backhaus forceps grip the drape without piercing. Most surgical kits stock the sharp variant because it provides more secure drape fixation.
Do I need 12 cm and 14 cm versions of the same hemostat?
Generally yes for high-volume surgical practices — the 12 cm gives precision in tight access, the 14 cm gives reach. For smaller practices, choose the size that matches the access requirement of the procedures most commonly performed: 12 cm for periodontal microsurgery, 14 cm for general oral surgery and exodontia.
