A small straight-edged strip intended to be used to measure the length of internal or external anatomy, devices or instruments in a clinical setting. It is marked in units of length (i.e., inches, millimetres and/or centimetres), and may be an independent bendable strip applied to measured surfaces or a strip incorporated into a form convenient for measuring specific devices (e.g., screws). It is not dedicated to wound measurements. This is a reusable device.
