A needle holder has one job — to hold a curved needle firmly at the right angle while it passes through tissue — but getting it right depends on matching the instrument to the needle.
Match the jaw to the needle
- Fine jaws for small needles and fine sutures (roughly 5-0 and finer). Heavy jaws can flatten or bend small needles.
- Heavier jaws for large needles and heavy sutures. Fine jaws can be sprung or damaged by large needles.
- Tungsten carbide jaws grip more securely and resist wear — see our article on carbide instruments.
Match the length to the depth
Use the shortest instrument that reaches comfortably. Short needle holders (around 130–150mm) give the best control for superficial work; longer patterns (180mm and above) reach into deep cavities.
Common patterns
- Mayo-Hegar — the general-purpose UK needle holder in a range of lengths.
- Crile-Wood — narrower jaws for finer work.
- Gillies — combined needle holder and scissors, popular in plastic surgery and minor ops, letting one instrument suture and cut.
- Castroviejo — spring-handled micro needle holders for ophthalmic and microsurgery.
Signs it is time to replace or repair
- Needles rotate in the jaw under light pressure.
- Light passes between the closed jaws.
- The ratchet slips or fails to hold.
- The jaw pattern is visibly worn smooth.
