Abstract
Abstract A surgical aid for retaining displaced material in a surgical site in its displaced position. The aid consists of a wire core of aluminum or aluminum alloy or stainless steel and a covering of a suitable elastomer, such as dimethyl polysiloxane polymer, organo-metallically bonded or otherwise contiguous thereto. The aid is malleable, non-toxic and compatible with cell metabolism. It can be clamped to a retractor frame fixed relative to a surgical site and has major advantages over the use of sponges, towels and other surgical aids now in use. The aid has a body portion and a handle portion which can be held by an assistant or clamped to the frame, allowing the assistant to assume a more productive role in the operation or dispensing with him completely.
