Reference NH 10-242-04: Castroviejo-Jacobson Micro Needle Holder — Smooth Jaws, Curved, Without Ratchet, 20 cm (20.0 cm). The curved jaw improves visibility around tissue edges and around the surgeon’s hand — the standard configuration for most dissection and clamping tasks.
Ramón Castroviejo y Briones, a Spanish-American ophthalmic surgeon in New York from the 1920s onward, pioneered modern corneal transplantation. His name attaches to a family of microsurgical instruments — Castroviejo needle holders, scissors, and forceps — distinguished by spring-action handles (no finger rings), fine tips, and overall lengths optimized for the surgeon working under microscope. Castroviejo scissors are used in corneal and conjunctival cuts, microvascular anastomosis, and nerve repair. Tungsten carbide tips are standard in professional-grade variants. Lengths of 9 cm, 10 cm, and 11 cm cover ophthalmic, plastic, and microsurgical applications. The squeeze-to-cut handle permits much finer control than scissor finger-rings during microsurgery.
