This Sklar Blue Iris Hook Set features four Iris Hooks with varying hook diameters (1mm, 3mm, 4mm, and 6mm) on a 9 inch slender handle. This instrument is most commonly used in electrosurgical OB/GYN procedures involving the uterus. Sklar Blue electrosurgical instruments feature high quality stainless steel with an insulated coating. This safe coating prevents radio frequency currents from being transmitted through the instrument which reduces the burning of non-targeted tissue. Sklar Blue instruments are fully autoclavable and may also be cleaned ultrasonically. All Sklar Blue coated instruments comply with biological testing requirements for cytotoxicity, sensitization regulatory, and ISO 10993 requirements. They also comply with the Pre-Vacuum and Gravity Cycle Steam Sterilization Validation of ANSI/AAMI ST79. Sklar Blue electrosurgical coatings are guaranteed for one year against manufacturing defects.
