A tube-like instrument, apparently broken, with a locking mechanism similar to those used to lock obturators into arthroscope sheaths. The hollow tip appears to be snapped or severed with a portion of the tip missing. There is a dark red and an off-white band of marking tape around the handle.
Note that this artifact was received in a resealable plastic bag labeled “Watanabe Cannulas.” However, it is not a cannula and does not match obturators shown in Watanabe arthroscope trade literature. The locking mechanism is not of the same type used in Watanabe instruments in this collection.
