Medical ruler, single-use

This category covers single-use medical rulers designed to measure anatomical structures, instruments, or surgical devices during clinical procedures. These straight-edged strips are marked in inches, millimeters, or centimeters and may be bendable to conform to the surfaces being measured. They serve as disposable tools for accurate length assessment in diagnostic, surgical, or treatment settings.

As single-use items, these devices are intended for one patient application only and are typically supplied sterile or non-sterile depending on the intended use. They are classified as measuring instruments rather than implant sizers or wound-measuring tools. Regulatory classification varies by jurisdiction and is determined on a per-device basis.
