Abstract
A disposable sterile sleeve is provided which is removably attachable to a video camera of an arthroscope. The sleeve comprises a flexible elongate tubular shroud and a rigid annular mounting collar. The shroud is open ended with the collar rotatably attached to one open end by a connector member providing independent rotation of the collar relative to the shroud. A pull tab is attached to the opposite open end of the shroud to facilitate extension of the shroud over the camera. The sleeve may be compacted for storage prior to use by tightly scrunching the shroud together, thereby folding it onto itself. To attach the sleeve to the camera, the video camera is inserted through the compacted shroud until it engages the collar. A male thread provided on the camera is threaded into a female thread provided on the collar and the shroud is then extended over the camera by pulling on the tab to draw out the folds in the shroud.
