Trocar and Sheath (Linvatec)

Health Sciences · Robert W. Jackson Arthroscopy

A metal blunt-tip trocar is inserted into a matching metal arthroscope sheath.

The trocar (model 8467) may be removed by depressing a round, spring-loaded collar. The trocar has a rounded base with a flattened area on its perimeter.

The sheath (model 8462) has a port for a fiber optic light source as well as a single port for an irrigation system. Between them is a rotating collar to secure the arthroscope in place.

A matching arthroscope has not been located within the collection.

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 artifact has very slight signs of wear. For instance, there are some very light scratches on the port for the fibre optic light source.
