Function:

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.

This set contains several early examples of the Watanabe “Type 21” Arthroscope. I also contains a number of related artifacts, including several curved metal tubes, whose purpose has not yet been identified.
