The 4 1/4 Castro Suturing Forceps with .3 Teeth, Titanium are specialized surgical instruments used primarily for handling sutures during delicate procedures, such as those in ophthalmic or microsurgery. Made of titanium, the forceps are lightweight, durable, and resistant to corrosion. Titanium is often used in surgical instruments because it is biocompatible, strong, and non-reactive, making it ideal for use in sensitive environments like surgeries involving the eye or other delicate tissues.
