A container intended to provide a suitable platform for placing/containing many medical/surgical instruments and related items during a clinical procedure; it might in addition be used during, but not dedicated to, reprocessing/sterilization procedures. It may be in the form of a shallow vessel with a raised rim, a deeper cassette-like device, or a flat or angled surface; it might include a lid. It may be designed to fit into other devices such as supply trolleys, storage systems and sterilizers, or designed to attach to a surgical/treatment table where it may be placed over the patient. This is a reusable device.
