<p>A sleeve-type wound retractor has at least two pieces: a reusable ring and a single-use sleeve. The reusable ring is sterilized before surgery in a conventional fashion. Before surgery and in a sterile environment, such as the operating room, the ring is fasted to one end of the sleeve to form a wound retractor. The other end of the sleeve has another ring which may be permanently attached to the sleeve or which may also be attached to the sleeve in the sterile environment. The completed wound retractor, comprising the two rings and the sleeve, functions as the conventional incremental wound retractor by winding the sleeve around the outer ring during use.</p> |
