DEVICE: Surgical Microscope MM80/YOH (04589698450268)

A general-purpose, surgical, light (optical) magnification instrument, usually stereoscopic, designed to magnify minute structures, e.g., nerves or vessels in the performance of delicate surgical procedures which require high magnification by transmitted light. An operating microscope will often be equipped with motorized focusing, adjustable magnification mechanisms (manual, zoom or both), backup lamps, and inclined tubes that permit the surgeon to see the field from a vertical perspective while keeping the head erect. Dual or multiple observation capability and the optical integration of still, motion picture and video cameras are common features. It can be fixed or mobile.

A light (optical) magnification instrument, usually stereoscopic, designed to magnify minute structures within the neurological fields for surgery, typically the brain or spine or surroundings in the performance of neurological surgical procedures which require high magnification by transmitted light. It will often be equipped with motorized focusing, adjustable magnification mechanisms (manual, zoom or both), backup lamps, and inclined tubes that permit the surgeon to see the field from a vertical perspective while keeping the head erect. Dual or multiple observation capability and the optical integration of still, motion picture and video cameras are common features. It is usually fixed.

A lens or lens group that forms the part of the optical system of a microscope closest to the object. It is used to magnify the viewed image. The objective may be supplied singularly, in pairs, or in sets of increasing magnification.

A light (optical) magnification instrument designed to magnify minute structures (e.g., nerves, vessels) in the performance of ear, nose, and/or throat (ENT) surgery requiring high magnification and adjustable focusing. It typically consists of a stereo microscope (standard or modified) and a mobile floor stand or wall or ceiling mount. It is usually held by an adjustable arm attached to the support mechanism and equipped with motorized focusing, adjustable magnification systems (manual, zoom, or both), backup lamps, and inclined tubes. Dual- or multiple-observation capability and the optical integration of still, motion picture, and TV cameras are common features.

A non-sterile, mains electricity (AC-powered) device assembly designed for viewing intraoperative blood flow in the cerebral vascular area, in bypass grafts during coronary artery bypass graft (CABG) surgery, and during plastic and reconstructive surgery. It enables a surgical microscope to produce excitation light and resolve fluorescence from the fluorescent agent indocyanine green (ICG). Fluorescent signals depict the distribution of the infrared dye in the patient's blood vessels during the operation. The system is attached to a compatible surgical microscope and typically includes an ICG filter, a near infrared (NIR) charge-coupled device (CCD) video camera, and connecting cables.
