Kelly and Crile forceps are close enough in size and shape that the jaw is the only place the difference actually shows: one is serrated along half its length, the other along the whole thing, and that alone changes what each is meant to grip. Mosquito sits alongside both as the smaller-scale pattern covered in our forceps buyer's guide, not a third variation on the same theme.
The one difference that actually matters: serration length
A Kelly forceps' jaw is serrated only on the distal half — the portion nearest the tip — leaving the back half near the box lock smooth. A Crile forceps carries the same transverse serration pattern along the entire jaw, tip to hinge. That is the defining difference between the two patterns; overall length, curvature options and box-lock construction are essentially shared.
What the serration difference actually changes
- Crile — full-length serration grips medium-to-large or arterial vessels securely under pressure, where slipping is the failure mode to avoid.
- Kelly — half-serrated jaw gives controlled compression on softer or fattier tissue, without the more aggressive full-length grip Crile is built for.
- Both are supplied straight or curved and in broadly comparable lengths, so neither pattern is a "bigger" or "smaller" version of the other — the jaw serration is the actual specification.
Where mosquito fits in
Mosquito forceps aren't a third point between Kelly and Crile on the same scale — they're a separate, smaller pattern (commonly around 12.5cm against Kelly and Crile's 14cm and up) built for fine vessels and delicate work, covered in full in our Kelly, mosquito and artery forceps buyer's guide. Deciding between Kelly and Crile is a question of grip pattern for a given vessel size; deciding to add mosquito is a question of scale for finer work entirely.
What to specify in an RFQ
- Pattern by name — Kelly or Crile, not "artery forceps" generically
- Serration: half-length (Kelly) or full-length (Crile), stated explicitly since this is the actual functional difference
- Straight or curved jaw
- Steel grade and finish (see our steel-grades guide)
- Whether mosquito-scale forceps are also needed alongside, for finer vessel work
