Needle Holders Guide: Mayo-Hegar, Olsen-Hegar, Micro and TC Explained
A needle holder has one job: hold a curved suture needle firmly at the right angle while it passes through tissue. The pattern, jaw and length you choose decide how well it does that job for a given needle and depth of field. This guide explains the common needle holder patterns, what the jaw options mean, and how to match a needle holder to the suture you use.
The anatomy of a needle holder
- Jaws: short and strong compared with a hemostat, so they grip a needle without letting it rotate. The jaw face can be smooth, serrated or cross-hatched.
- Box lock: the joint. Wear here causes the jaws to misalign.
- Ratchet (lock): holds the needle without constant squeezing. Most general needle holders have one; many micro patterns come with or without.
- Handles: finger rings on most patterns; spring handles on micro patterns such as Castroviejo.
Common general surgery patterns
| Pattern | What sets it apart | Typical use |
|---|---|---|
| Mayo-Hegar | The standard ring-handled needle holder, in lengths from about 5" to 12" | General purpose; medium and large needles |
| Olsen-Hegar | Scissors built into the jaws behind the gripping surface | Suturing and cutting with one instrument, e.g. skin closure |
| Crile-Wood | Narrower, more tapered jaws than Mayo-Hegar | Finer needles and deeper, tighter fields |
| Webster / Halsey | Short and light with small jaws, often smooth | Fine sutures, plastic and superficial work |
| Heaney | Curved jaws | Deep pelvic work, including gynecology |
| DeBakey / Ryder | Fine, slender jaws on longer shafts | Vascular and cardiovascular suturing |

Micro needle holders
For ophthalmic, plastic, hand and microvascular work, micro needle holders use spring handles held like a pencil. The main choices are:
- Straight or curved jaws. Curved jaws help keep the tip in view under magnification.
- With or without lock. A lock holds the needle steady; many surgeons prefer no lock for the smoothest release under the microscope.
- Stainless steel or titanium. Titanium is lighter and non-magnetic.
Examples: Castroviejo Needle Holder, Curved, Delicate, With Lock, Micro Needle Holder 160mm Curved, Without Catch and Titanium Needle Holder Curved Without Catch.
Jaw faces: smooth, serrated or tungsten carbide
- Smooth jaws will not damage fine suture material and are the usual choice for very fine sutures.
- Serrated jaws grip larger needles more securely.
- Tungsten carbide (TC) inserts have a hard cross-hatched face that grips firmly and resists wear better than plain steel. TC needle holders are traditionally identified by gold-coloured handles. See Mayo-Hegar Needle Holder 7" - Tungsten Carbide and the smooth and serrated versions of the TC Halsey Needle Holder 5".
How to choose
- Match the jaw to the needle. Fine jaws for small needles; heavier jaws for large needles. Clamping a large needle in fine jaws bends the needle and springs the jaws.
- Match the length to the depth. Short (5" to 6") for superficial closure; long (8" to 12") for deep abdominal, pelvic or thoracic work.
- Decide on built-in scissors. An Olsen-Hegar saves an instrument change but needs care so the suture is not cut by accident.
- Choose the jaw face. Smooth for fine sutures, serrated or TC for secure grip on larger needles.
- Left-handed users can choose left-handed patterns, such as the left-handed Mayo-Hegar, where the ratchet releases naturally in the left hand.
Care and inspection
- Check that the jaws meet evenly along their length and that a closed needle does not rotate.
- Check the ratchet holds on each tooth and releases cleanly.
- Clean the box lock and jaw face after every use, and process with the ratchet open.
- Retire any needle holder whose jaws no longer hold a needle without it turning; a slipping needle is harder to control.
Frequently asked questions
What is the difference between a needle holder and a hemostat?
A needle holder has shorter, stronger jaws made to stop a needle turning. A hemostat has longer, lighter jaws made to clamp vessels. Using a hemostat as a needle holder damages it.
What is the difference between Mayo-Hegar and Olsen-Hegar?
Both share the same basic shape. The Olsen-Hegar adds scissor blades behind the jaws, so you can cut the suture without picking up separate scissors.
Do I need a lock on a micro needle holder?
It is personal preference. A lock holds the needle for you; a lockless pattern gives a smoother release. We stock both, for example the McPherson Needle Holder with lock and without lock.
