Structures suspended from the ceiling that are designed to support operating microscopes. These booms typically consist of a ceiling fixture, a support system equipped with a movable arm, a pendant head, and an equipment carrier for the microscope. A steel tube on the ceiling fits the pivot bearing of the support system below it, which generally includes a fixed vertical support arm and a movable single-support arm that allows rotation of the pendant head. The equipment carrier attaches below the pendant and supports the microscope. Operating microscope ceiling-mounted booms are usually installed in surgical rooms and used in procedures such as neurosurgery, microsurgery, and ophthalmology; they may also be installed in dental surgery cabinets.
