Businesses in the surgical equipment category supply instruments and equipment used in operating theatres, treatment rooms and other clinical settings. Their products may include scalpels, scissors, forceps, clamps, retractors, surgical lights, operating tables, suction equipment and devices for monitoring or supporting patients during procedures. Some suppliers focus on particular medical specialities, while others offer a wider range of general-purpose equipment. Customers may be able to obtain reusable instruments, single-use items, storage and sterilisation products, and equipment for setting up or fitting out clinical spaces. Businesses may also provide technical advice on product selection, delivery, installation, maintenance and repair. Reusable equipment needs appropriate cleaning, inspection and sterilisation between uses; the relevant requirements depend on the product and how it is used.
