A Castroviejo needle holder is the spring-handled micro needle holder that periodontists, implant surgeons and oral surgeons reach for when the suture is fine and the tissue is thin. It has no finger rings. A spring opens the jaws, a light thumb-and-finger pinch closes them, and a lock holds the needle until you release it. That design is what makes it the standard instrument for 5-0 to 8-0 sutures under loupes or a microscope.
But "Castroviejo" covers several different designs, and the lock, the spring and the jaw material change how each one feels over a long case. This guide explains the differences and lists every Helmut Zepf Castroviejo and micro needle holder we carry, so you can match the instrument to your technique. The full range is in our Micro & Castroviejo Needle Holders collection.
What is a Castroviejo needle holder used for?
A Castroviejo needle holder is used for fine suturing in periodontal, implant and oral microsurgery: papilla preservation, connective tissue grafts, flap closure around implants, and any procedure where precise needle placement in thin soft tissue matters more than gripping force. Its spring action and ring-free handle let you rotate the instrument between your fingers and open and close it with minimal hand movement, which reduces fatigue over long suturing sequences.
What makes a Castroviejo different from other needle holders
A conventional needle holder, such as a Mayo-Hegar, has finger rings and a ratchet. You close it through the rings and release it by disengaging the ratchet. A Castroviejo skips the rings entirely. A spring holds the jaws open, you close them with a light pencil grip, and a lock (usually a spinlock) holds them shut. Releasing is a small squeeze, and the spring reopens the jaws instantly. For fine sutures, that means more control and less wrist movement. For a side-by-side with the ring-handled patterns, see our dental needle holders comparison.
Lock and spring designs compared
Zepf makes the Castroviejo in several designs. The differences are in how the lock works and how the spring is built:
| Design | Key trait | Best for |
|---|---|---|
| Spinlock | Classic spring action with a twist-style lock | General micro-suturing |
| Lock and protected inner spring | Spring enclosed inside the handle, shielded from debris | High-frequency use and easier reprocessing |
| Double spring (Dr. Axel Kirsch) | Castroviejo pattern with a double spring, designed with Dr. Axel Kirsch | Implant and periodontal surgery |
| TOUCHGRIP | Ergonomic ring-free handle; available with a dedicated lock | Clinicians moving over from ring-handled instruments |
| Double action | Two-stage jaw movement with fine 0.6 mm jaws | Confined microsurgical fields and the finest sutures |
Why tungsten carbide jaws matter
Almost every Castroviejo we carry has tungsten carbide (TC) jaw inserts. Carbide holds its fine cross-cut grip pattern far longer than plain steel, so the needle is less likely to slip or rotate as you drive it, and the jaws keep performing through many more sterilization cycles. When the jaws do wear, the instrument can often be restored through our repair and reconditioning service rather than replacing the whole instrument.
Straight or curved?
Straight jaws suit most anterior and general access. Curved jaws improve your line of sight and reach in posterior and angled sites, and many surgeons keep one of each. Most Zepf patterns come in both.

How to choose
- First Castroviejo, or one instrument for everything: the straight 41.010.17TC spinlock, or the 41.200.17TC if you want the protected spring.
- Posterior and implant sites: add a curved version (41.011.17TC or 41.201.17TC).
- Anterior and confined sites: the shorter 16 cm 41.200.15TC or 41.201.15TC.
- Heavier threads: the wider-jaw TC-M versions (11 x 2.0 mm jaws, max. thread size 4.0).
- Finest sutures under the microscope: the double action 41.017.17 with 0.6 mm jaws.
- Coming from ring-handled needle holders: the TOUCHGRIP with lock (41.012.17HZU).
Pair your needle holder with fine scissors and tissue forceps from the same system. Our Castroviejo scissors guide covers the matching scissors.
Frequently asked questions
What is a Castroviejo needle holder used for? Fine suturing in periodontal, implant and oral microsurgery, where controlled needle placement in soft tissue matters more than gripping force.
Is a Castroviejo the same as a micro needle holder? A Castroviejo is a specific spring-handled pattern within the broader micro needle holder category. Other micro needle holders use different mechanisms, such as the double action or slim-handle designs listed above.
What does "spinlock" mean? A twist-style lock that holds the jaws closed against the spring until you release it, instead of a ratchet between finger rings.
Why choose tungsten carbide jaws? Carbide inserts keep their grip pattern much longer than steel, reducing needle slippage and rotation and extending the life of the instrument.
What suture sizes does a Castroviejo hold? Standard Castroviejo jaws are made for fine sutures, typically 5-0 to 8-0. For heavier threads, the TC-M versions have wider 11 x 2.0 mm jaws rated for a maximum thread size of 4.0.
Can I use a Castroviejo for large flap closures? It is designed for fine, precise work. For larger closures and heavier sutures, a ring-handled needle holder such as a Mayo-Hegar is generally more appropriate.
How should Castroviejo needle holders be sterilized? Follow the manufacturer's reprocessing instructions, and inspect the spring, lock and jaw alignment at each cycle. Protected-spring designs are easier to clean because the spring is enclosed.
