House Strut Caliper, 4.0mm Tip, Hexaganal Handle, Malleable Shaft, Overall Length 6.7" (168mm)

Used during stapes surgery to measure prosthesis length between incus and footplate, this House strut caliper carries a 4.0mm tip on a malleable 168mm shaft. The hexagonal handle resists rolling on the Mayo stand and allows the surgeon to bend the shaft into the working angle dictated by middle‑ear anatomy. Stainless steel construction holds calibration through repeated stapedotomy cases and steam sterilization.
