CASTROVIEJO CALIPER 45° ANGLE 20mm SCALE 3 1/2

CASTROVIEJO CALIPER 45° ANGLE 20mm SCALE 3 1/2

The Castroviejo Caliper 45° Angle 20mm Scale 3 1/2 is constructed from German-grade surgical stainless steel with a passivated corrosion-resistant finish. The instrument measures 9 cm (3.5 inches) overall, with two slim crossed shafts joined at a central ball-joint pivot. Its defining feature is the bilateral 0-20mm graduated base scale etched in 1 mm increments, paired with tips angled precisely at 45 degrees — a geometry that separates this variant from both straight and curved alternatives within the Castroviejo family.

The knurled thumb-screw on the lateral shaft makes this fully adjustable, locking the jaw opening firmly once bone or tissue contact is made and preventing drift before the measurement transfers. As a castroviejo curved caliper variant, it tolerates full autoclave sterilization at 134°C and is compatible with ultrasonic cleaning and chemical disinfection. Passivation guards the steel surface between sterilization cycles, and standard boil, performance, and shape quality-control tests confirm reliable reusability before dispatch.

Ophthalmic surgeons use the Castroviejo Caliper 45° Angle 20mm Scale 3 1/2″ during strabismus surgery and scleral measurement procedures. The Castroviejo calipers Angled tip geometry allows the surgeon to approach the extraocular muscle or scleral surface from an oblique angle, reaching posterior anatomical zones inaccessible to straight-tip variants. The surgeon opens the tips across the target tissue, reads the graduation scale directly, and locks the measurement before recording the recession or resection distance.

Instruments built for the orbital field must account for angles the straight line cannot reach, and Leader Surgical sources exactly these variants for that reason. This 45-degree caliper fills a specific gap in the ophthalmic tray, giving surgeons the oblique access and scale accuracy that posterior eye procedures demand, backed by verified material and sterilization standards.

What is the primary use for this specific 45° angled model?
The 45° angled tips are designed for better visibility and access in deep or confined surgical areas. It is commonly used in ophthalmology for strabismus surgery, dentistry for measuring bone structures or dental implants, and plastic surgery (e.g., rhinoplasty).
