What is the medical term for instrument used viewing joints?

The medical term for the instrument used for viewing joints is an arthroscope. Arthroscopy is a minimally invasive surgical procedure that allows a surgeon to visualize, diagnose, and treat problems inside a joint. The arthroscope is a small, flexible tube with a camera on the end that is inserted into the joint through a small incision. The camera displays the images on a video monitor, allowing the surgeon to see inside the joint and perform any necessary repairs.
