Calipers
Surgical calipers and rulers measure in the operating field. Ophthalmic calipers mark incision and resection distances in fractions of a millimetre; plastic surgeons use keyhole calipers and rulers to plan symmetrical markings; neurosurgeons use calipers to plan burr hole and craniotomy sites.
This collection covers stainless steel calipers and rulers, rigid and flexible. All are reusable and autoclavable, and every instrument carries our 5-year warranty.
