  • Patent number: 4174816
    Abstract: A sterile surgical cord and tube retractor for use by surgeons while operating to maintain accessories, such as suction tubes and cauterizing forceps, within easy reach of the surgeon without obstructing the surgical field with tubing and cord when not in use. The device comprises a housing adapted to be supported on the usual instrument table positioned adjacent the surgical field, and in turn supports the instrument tray. A plurality of spring tensioned retractors within the housing separately hold lengths of tubing and cord, permitting them to be withdrawn from the housing for use and then retracted back into the housing.
