The Mayo-Hegar and the Olsen-Hegar are the two needle holders buyers ask about most. From a distance they look almost the same: ring handles, a ratchet and short, strong jaws. The difference is a small pair of scissor blades built into the Olsen-Hegar just behind the jaws. That one feature changes who should use it, how fast a surgeon can close a wound and how easily a suture gets cut by mistake.
This guide compares Olsen-Hegar vs Mayo-Hegar needle holders side by side so clinics, hospitals and distributors can stock the right pattern.
What is a Mayo-Hegar needle holder?
The Mayo-Hegar needle holder is the standard needle holder of general surgery. It has:
- Ring handles with a three-step ratchet to lock the needle at different pressures
- Short, broad jaws with cross-serrations (or a tungsten carbide insert) to stop the needle rotating
- Lengths from about 14 cm to 26 cm, so the same pattern covers superficial and deep closures
Because it only holds the needle, a second person (or a separate pair of suture scissors) cuts the suture after each knot.
What is an Olsen-Hegar needle holder?
The Olsen-Hegar needle holder combines a needle holder and suture scissors in one instrument. The jaws grip the needle exactly like a Mayo-Hegar, but behind the jaws there is a short pair of cutting blades. The surgeon ties the knot, opens the instrument slightly, slides the suture between the blades and cuts it, all without putting the instrument down.
It is usually made in shorter lengths (around 12-19 cm), because it is designed for superficial suturing rather than deep cavities.
Olsen-Hegar vs Mayo-Hegar: side-by-side comparison
| Feature | Mayo-Hegar | Olsen-Hegar |
|---|---|---|
| Function | Holds the needle only | Holds the needle and cuts the suture |
| Typical lengths | 14-26 cm | 12-19 cm |
| Best for | General, deep and assisted surgery | Skin closure, minor and solo procedures |
| Speed when working alone | Slower (needs separate scissors) | Faster (one instrument) |
| Risk of cutting suture by accident | None | Possible if the jaws are not handled carefully |
| Main users | Hospitals, operating theatres | Veterinary clinics, dermatology, A&E, GP minor surgery, students |
| TC insert available | Yes | Yes |
When to choose a Mayo-Hegar
- Operating theatres with an assistant. The assistant cuts the suture, so built-in scissors add no value.
- Deep closures. Long Mayo-Hegar patterns (20-26 cm) reach into the abdomen or chest; Olsen-Hegar is not made that long.
- Delicate or expensive sutures. There is no blade near the jaws, so there is no risk of cutting the thread while tying.
- Major and laparotomy sets. Most hospital surgical instrument sets specify Mayo-Hegar in two or three lengths.
When to choose an Olsen-Hegar
- Veterinary surgery. Vets often operate without a scrubbed assistant. The Olsen-Hegar is the standard needle holder in spay and castration packs. See our veterinary instruments.
- Minor surgery and skin closure. GPs, dermatologists and emergency departments close small wounds quickly with one instrument.
- Training kits. Medical and veterinary students learn suturing with a single tool.
- Field and mobile kits. Fewer instruments means smaller, lighter kits.
Tungsten carbide or standard jaws?
Both patterns are made with plain stainless steel jaws or with tungsten carbide (TC) inserts. TC jaws have a fine diamond-pattern grip that holds the needle firmly and lasts many times longer before wearing smooth. TC versions are easy to recognise by their gold-coloured handles. For high-volume suturing, TC is better value over the life of the instrument. Read more in tungsten carbide vs stainless steel instruments.
Quality checks before you buy
- Jaw alignment: the jaws should meet evenly along their whole length, with no light visible between them.
- Ratchet: each step should engage cleanly and release smoothly without springing open.
- Needle grip: clamp a needle on the second ratchet step; it should not rotate when pushed.
- Olsen-Hegar blades: the scissor section should cut a suture cleanly at the tip, without chewing it.
- Steel and finish: martensitic stainless steel, passivated, satin finish to reduce glare.

FAQs
What is the difference between Olsen-Hegar and Mayo-Hegar needle holders?
Both hold a suture needle, but the Olsen-Hegar has built-in scissor blades behind the jaws so the surgeon can cut the suture without changing instruments. The Mayo-Hegar holds the needle only.
Why do veterinarians use Olsen-Hegar needle holders?
Vets often operate without an assistant. The Olsen-Hegar lets them suture and cut with one instrument, which saves time and reduces the number of instruments in the pack.
Can an Olsen-Hegar accidentally cut the suture?
Yes, if the suture slips into the scissor section while tying. Careful technique avoids this, which is why many surgeons prefer a Mayo-Hegar for delicate work.
What sizes do Mayo-Hegar needle holders come in?
Common lengths are 14, 16, 18, 20, 24 and 26 cm. Shorter ones are for superficial suturing, longer ones for deep closures.
Can I order needle holders with my own brand?
Yes. Pak Line manufactures Mayo-Hegar and Olsen-Hegar needle holders, standard and tungsten carbide, with laser-marked private labels and custom packaging.
