Castroviejo Needle Holders — Pattern and Clinical Use
Ophthalmic suture is measured in microns, and the needles are correspondingly tiny. The Castroviejo holds them with fine jaws under light spring tension rather than ring handles, so the surgeon can rotate the instrument between the fingers to drive a curved needle through cornea or sclera without changing grip. Locking patterns hold the needle securely; non-locking patterns allow faster repositioning.
Jaw fineness and tip alignment are critical at this scale, and tungsten-carbide inserts are effectively standard because a micro needle polishes plain stainless jaws smooth very quickly.

Material, Finish and Quality Control
We forge Castroviejo needle holders from AISI 420 stainless with tungsten-carbide inserts. Jaw tips are aligned and inspected under high magnification, and carbide inserts checked for secure bonding at micro scale. Each batch passes Rockwell hardness testing, dimensional checks on jaw tip alignment under magnification, and visual inspection under our ISO 13485 system before passivation and final finishing. Mirror and satin finishes are both available — satin is usually specified where glare under operating lights is a concern.
Who Sources Castroviejo Needle Holders From Surgical Star
Castroviejo needle holders are a premium ophthalmic and microsurgical line sold to eye hospitals and micro-surgery distributors, with carbide versions the default specification.
OEM, Certification and Ordering
Every Castroviejo needle holders can be produced as a private-label line: your logo laser-marked on the handle, your catalog numbers, and your own printed packaging, manufactured from your drawings or a reference sample. Production runs inside a documented ISO 13485 quality system, with CE marking under EU MDR 2017/745 and US FDA establishment registration behind it. Your shipment carries a certificate of conformity plus the ASTM F899 material certificate for the grade actually used.
Minimums stay deliberately low so a new brand can launch without a heavy first order, and pricing is quoted direct from the factory on volume tiers. Bulk production usually takes four to six weeks from sample approval, shipped DDP with export paperwork and HS codes handled. See how OEM & private label works →

Frequently Asked Questions
Why do Castroviejo holders have round handles?
So the surgeon can rotate the instrument between the fingers to drive a curved needle through tissue without changing grip.
Locking or non-locking?
Locking holds the needle securely for driving; non-locking allows faster repositioning. Preference varies by surgeon, so most buyers stock both.
Are carbide jaws necessary?
Effectively yes at this scale. A micro needle polishes plain stainless jaws smooth very quickly, after which the needle rotates in the jaw.
Can you manufacture these under our own brand?
Yes — full OEM and private label. We laser-mark your logo and catalog numbers, pack in your branded boxes, and work from your drawings, tech pack or a reference sample, with a pre-production sample approved before any bulk run.
