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.
Claims46
A surgical retractor comprising an elongated body of polymeric material having a polymeric surface which is non-toxic to cells and characterized in being three-dimensionally deformable merely by bending and without torsional deformation, with one end of said retractor fixedly secured at a point in space, into a full circle the plane of which may be in any angular orientation relative to said point in space.
A surgical retractor for use in retraction of parts of the patient's body during surgery, comprising:
- a. an elongated portion which is bendable as an integral part of said retractor at any region along said elongated portion without torsional deformation in each of two directions at right angles to each other and to the direction of the longitudinal axis of said elongated portion in said region, and which retains the shape of the bend produced;
- b. said portion including an elongated body of polymeric material having a surface which is polymeric and non-toxic to cells.
A surgical retractor for use in retraction of parts of the patient's body during surgery, comprising:
- a. a handle which is bendable as an integral part of said retractor at any region along said handle in each of two directions at right angles to each other and to said handle's longitudinal axis in said region, and which retains the shape of the bend produced;
- b. said handle having a surface which is polymeric and non-toxic to cells;
- and
- c. a body portion at one end of said handle and integral therewith;
- d. said body portion being bendable and retentive of the shape of the bend produced and having a polymeric surface which is non-toxic to cells.
