25° “Lumina”, “Panoview” Arthroscope and Sheath (Wolf)

Health Sciences · Robert W. Jackson Arthroscopy

A metal optical instrument with a long, thin, cylindrical stem. The instrument consists of two parts: an arthroscope and its corresponding sheath.

A black coloured eyepiece is located one the arthroscope. Protruding from the barrel of the instrument, adjacent to the eyepiece, is a port for a fiber optic light source. There is a narrow red band near the base of this port. There is a light blue band around the barrel of the arthroscope just past the port.

The arthroscope is fitted into a sheath with two ports protruding opposite each other from its perimeter. Where the sheath meets the arthroscope, there is a collar that locks the arthroscope into place.

An arthroscope is an optical instrument for viewing the interior of a joint during a surgical operation. Its development made possible minimally invasive surgery for many knee operations. It significantly improved diagnoses and healing times for many knee conditions. Specialized arthroscopes may also be used on smaller joints.


There are light abrasions, nicks, and scratches across the surface of the instrument. There are small nicks in the flat portion of the barrel of the sheath. Some of the lettering has been damaged, especially on the eyepiece.

Associated Instruments:

2020.JAC.6 is the same model of arthroscope and sheath.
