Arthroscopes

Arthroscopes are telescopic devices that enable visualization and therapeutic treatment of the interior of a joint (e.g., knee, shoulder, wrist, elbow, hip, ankle). An arthroscope consists of a magnifying-lens system sealed within a rigid tube and is available in two basic optical designs: rod-lens system (long, rod-like lenses separated by small spaces) and single-image fiber system (narrower in diameter and containing one imagetransmitting fiber bundle).

In both designs, the lens system is surrounded by optical fibers that transmit light to the interior of the joint from a distant source. Accessory equipment includes irrigation/distention systems, fiberoptic light sources, camera systems, laser, and electrosurgical and shaver accessories. Diagnostic and operating arthroscopes function similarly.

Once the arthroscope is inserted, the lens system magnifies the inside of the joint by gathering light and focusing that light to form a real image. Surrounding optical fibers transmit light to the far end of the scope to aid visibility. The field of view is proportional to an arthroscope’s diameter and a variety of diameters are offered by manufacturers. An instrument channel can allow tools to be passed down the optical line of the arthroscope.
