Kelly vs Halsted-Mosquito vs Crile Hemostats: Which Hemostat for Oral Surgery?

Selecting the right kelly hemostat — or choosing between a Kelly, a Halstead-Mosquito, and a Crile pattern — comes down to jaw length, serration, and how much clamping surface a given oral surgery case actually needs. All three are classic hemostatic forceps patterns, but they are not interchangeable across procedures.

Revised on October 1, 2026

A dental hemostat is used to clamp a bleeding vessel, stabilize a flap edge, or hold a ligature while a knot is tied, and the wrong pattern in a small surgical field can slow the operator down or crush tissue unnecessarily. Helmut Zepf manufactures each of the common patterns used in oral and maxillofacial procedures, as part of its full Helmut Zepf Dental Instrument Collection, in both straight and curved jaw options.

This comparison breaks down where a Kelly hemostat, a Halstead-Mosquito hemostat, and the Crile pattern each fit in an extraction or flap-surgery workflow, so you can match the instrument to the case rather than defaulting to whatever is already on the tray.

Kelly Hemostat: Half-Serrated Jaws for Larger Vessels and Flaps

The Kelly hemostat has box-lock jaws with transverse serrations on the distal half of the jaw only; the proximal half is smooth. Its longer, heavier jaw still gives it a broader clamping surface than a mosquito pattern. That makes it well suited to larger vessels, thicker soft-tissue flaps, and general hemostasis during extractions, apicoectomies, and minor oral surgery where a mosquito's finer tip would be more delicate than necessary.

Best for: Isolating a bleeding vessel or holding a reflected flap during routine extractions and minor surgery — the Kelly Hemostatic Forceps, Curved, 5-1/4" (No. 23.099.14) gives a secure grip across its serrated distal jaw without excessive tip pressure. A straight Kelly hemostat (No. 23.098.14) is the better choice when direct in-line access is available.

Halstead-Mosquito Hemostat: Precision Clamping in Confined Fields

The mosquito hemostat is a scaled-down pattern with narrower, finer jaws and shorter serrations, built for delicate work rather than bulk clamping. It is the standard choice for isolating small bleeders, holding fine sutures or ligatures, and working in confined intraoral spaces where a Kelly's broader jaw would obstruct visibility.

Best for: Fine bleeder control and ligature handling in a tight surgical field — the Halstead-Mosquito Hemostatic Forceps, Straight, Serrated, 1 x 2 Teeth (No. 23.058.12) and its curved counterpart (No. 23.059.12) both hold securely on small-diameter vessels without excess tissue trauma.

Where the Crile Pattern Fits

The Crile hemostat sits between the Kelly and mosquito patterns in general surgical use: unlike the Kelly, its jaws are serrated along their full length, on a slightly shorter, more tapered profile. It is a common general-purpose clamp in medical operating rooms; in dental and oral surgery, that same general clamping role is most often filled by the Kelly hemostat, since an oral-surgery instrument range is built around patterns proven specifically in intraoral procedures.

Other Hemostat Patterns: Kocher, Rochester-Pean and Hartmann

Kelly, mosquito and Crile are the patterns most people mean by "hemostat", but three more locking patterns in the Helmut Zepf range answer specific needs. They differ in jaw length, serration and whether the tip carries teeth.

Kocher forceps (Kocher clamp). The Kocher is the pattern defined by its teeth: serrated jaws plus 1 x 2 interlocking teeth at the tip, so one tooth on one jaw seats between two on the other. That tip grips tough or fibrous tissue that would slip out of plain serrations, which is why a Kocher clamp is used for holding tissue that is being removed or retracted rather than for fine vessels, where the teeth would do more damage than a smooth-jawed clamp. Zepf makes it at 12 cm (5-1/4") in straight (No. 23.104.14) and curved (No. 23.105.14) versions; see the Kocher Hemostatic Forcep Collection.

Rochester-Pean forceps. The Rochester-Pean is the long, heavy clamp of the group: jaws serrated along their full length, like the Crile, on a larger frame built for clamping bigger vessels and bulkier soft tissue. Zepf offers it in 14, 16 and 18 cm, straight (No. 23.106.14, 23.106.16, 23.106.18) and curved (No. 23.107.14, 23.107.16, 23.107.18). The 14 cm size is the intraoral choice; the 16 and 18 cm lengths suit extraoral and maxillofacial work where reach matters more than a compact handle. Browse the Rochester Pean Forcep Collection.

Hartmann forceps. The Hartmann is the compact pattern: serrated jaws, no teeth, on a 10 cm frame that is shorter than the 12.5 cm Halstead-Mosquito. It is made for confined intraoral fields, anterior work with direct line of sight, and clinicians who want the smallest clamp that still locks securely. Available straight (No. 23.050.10) and curved (No. 23.051.10) in the Hartmann Hemostatic Forcep Collection.

Between the mosquito and the Hartmann sits the 12 cm Micro-Halstead, offered plain or with 1 x 2 teeth, in the Micro-Halstead Hemostatic Forcep Collection. Every pattern on this page is in the full Hemostatic Forcep Collection.

Kelly vs Halstead-Mosquito vs Crile: Side-by-Side

Best for: A single go-to hemostat for general chairside use — the Kelly Hemostatic Forceps, Curved, 5-1/4" (No. 23.099.14) covers the widest range of extraction and minor-surgery clamping needs without switching instruments mid-procedure.

Where the Kelly Hemostat Earns Its Place in Oral Surgery

Beyond general extraction hemostasis, the Kelly pattern covers most of the clamping and holding tasks that come up in oral, periodontal and implant surgery:

• Controlling bleeding during flap surgery, extractions and implant placement
• Grasping and retracting soft tissue
• Clamping small vessels and salivary ducts
• Temporary occlusion in periodontal and regenerative procedures
• Assisting with suture ligation and hemostasis

Using a Kelly Hemostat: Four-Step Technique

1. Select the pattern. Choose the curved Kelly (No. 23.099.14) for better visibility in posterior areas and the straight Kelly (No. 23.098.14) for anterior or in-line access.
2. Apply. Grasp the vessel or tissue with the tip of the jaw, then engage the ratchet for a secure hold.
3. Release. Use a one-handed release for efficiency when ligating or removing the forceps.
4. Maintain. Clean thoroughly after each use, paying attention to the box lock and ratchet, and follow Helmut Zepf reprocessing guidelines so the instrument keeps performing through repeated sterilization cycles.

FAQs

What is the difference between a Kelly hemostat and a mosquito hemostat?
A Kelly hemostat has a longer jaw, serrated on its distal half, built for broader clamping, while a mosquito hemostat is a smaller, finer-jawed pattern designed for delicate vessels and confined surgical fields.

Is a Crile hemostat the same as a Kelly hemostat?
They are closely related patterns, but they differ in serration: the Crile's jaws are serrated along their full length, while the Kelly's are serrated on the distal half only. The Crile's jaw is also typically slightly shorter and more tapered. In oral surgery, the Kelly hemostat is the more commonly stocked of the two.

What size hemostat is typically used for dental extractions?
A 5 to 5-1/4 inch (approximately 12.5 to 13 cm) hemostat, in either the Kelly or Halstead-Mosquito pattern, covers most routine extraction and minor oral surgery needs.

Should I choose a curved or straight hemostat?
Curved jaws improve visibility and access around a flap or in a posterior field, while straight jaws are preferred for direct in-line clamping and ligature work.

Can Halstead-Mosquito forceps be used for ligatures?
Yes — their fine jaw and secure box-lock make them a standard choice for holding suture material or a ligature while a knot is tied.

How should hemostatic forceps be reprocessed between patients?
Follow standard instrument reprocessing protocols — ultrasonic cleaning, inspection of the box-lock and jaw serrations, and autoclave sterilization per the manufacturer's instructions.

What is a hemostat?
A hemostat is a ring-handled forceps with a box lock and a ratchet that holds the jaws closed without continued hand pressure. It is used to clamp a bleeding vessel, hold a flap edge or ligature, and grasp tissue or material that must stay put while you work.

Hemostat vs forceps: what's the difference?
"Forceps" is the family name for any two-bladed grasping instrument, so a hemostat is one kind of forceps, a locking (ratcheted) hemostatic forceps. The forceps it is most often confused with are thumb forceps such as Adson and tissue forceps, which are spring tweezers with no lock: they hold only while you squeeze. Extraction forceps are a third, unrelated group built for tooth removal. Our Surgical Forceps Identification Guide compares all of them side by side.

Needle driver vs hemostat: can I use one for the other?
Not reliably. A needle driver (needle holder) has short, broad jaws with cross-hatched or tungsten carbide inserts that hold a curved needle without letting it rotate; a hemostat has longer, finer jaws with transverse serrations designed to clamp tissue. Holding a needle in a hemostat lets it twist and wears the serrations, and clamping tissue with a needle driver crushes more than it needs to. Keep a dedicated holder on the tray; our needle holder comparison covers the patterns.

What are the types of hemostats?
The common patterns are the Kelly (serrated on the distal half of the jaw), Halstead-Mosquito and Micro-Halstead (small, fully serrated, optionally with 1 x 2 teeth), Crile (fully serrated, a medical OR standard), Kocher (serrated with 1 x 2 teeth at the tip), Rochester-Pean (long, fully serrated, heavy) and Hartmann (compact, 10 cm). Each comes straight or curved. Helmut Zepf makes all of these except the Crile.
