    <P style="MARGIN: 0in 0in 10pt">This particular retractor consists of a long rod with two attached loops on either side and a central retractor blade. The loops can be pushed apart to open up the wound, and a ratcheting device holds them in place. The central blade can be raised or lowered to increase the view of the surgical field.</P>
