Abstract

Modified silhouette facelift surgical suture A modified silhouette facelift surgical suture includes a modified long needle (1) with a blunt lower end (2), a curved slit (3), a bifid upper end (4) and a separate polypropylene suture (7) which has knots (5), cones (6) and a half circle non-cutting small needle (8), such that the suture is stretched over the long needle (1) between the curved slit (3) and the bifid upper end (4) for proper surgical insertion.

Description

Modified silhouette facelift surgical suture

This invention relates to a modified silhouette facelift surgical suture. The use of the ordinary silhouette suture represents a minimal invasive technique for facial tissue suspension. It is composed of eight inch long needle with blunt lower end. The needle is made of stainless steel. A twelve inch long 3-0

polypropylene suture is attached to its terminal end. The suture contains ten silicone cones spaced with knots eight mm apart. It is ended with a half circle non- cutting surgical needle.

The procedure involves a temporal incision for subcutaneous insertion of the sutures. The long blunt needle in inserted under the skin through the temporal incision. Local anesthesia is used to perform the procedure.

The skin of the face is punctured by scalpel to get the needle out of it. This is done for each applied suture.

To overcome this, the present invention proposes a modified needle which can do the task without puncturing the skin of the face. However, temporal incision is required.

Unlike the classical silhouette suture, all the sutures which are required for the procedure can be introduced by one modified needle.

The suture is separate and includes cones and knots similar to the cones and knots of the classical silhouette suture.

The procedure may be done in a shorter time than the classical silhouette suture.

Procedure

The procedure is started with subcutaneous infiltration of local anesthetic. Excess knots are cut before the start of the procedure. The suture is applied over the face for proper decision. A small temporal incision is done under a septic technique. The suture is stretched and fixed over the long needle between the curved slit at the blunt lower end and the bifid upper end. The needle is inserted under the skin in the required direction. When the blunt end reached the targeted point, the suture is untied of the bifid end. When the needle is withdrawn the suture will stay in position by the effect of its knots and cones.

Surgical wax may be required to close the gap of the slit to avoid tissue trauma before needle insertion.

The invention will now be described solely by way of example and with reference to the accompanying drawings in which:

Figure 1 shows a modified long needle with a curved slit near to its blunt lower end , and a bifid upper end,

Figure 2 shows a separate polypropylene suture which is

stretched over the long needle,

Figure 3 shows possible three ways of connection between the lower end of the suture and the curved slit,

Figure 4 shows the classical silhouette suture.

In figure 1, a modified needle 1 is made of stainless steel is eight inch long. It includes a blunt lower end 2 and a curved slit

3 which is 5mm long, situated 5mm far from the blunt lower end. The opening of the slit 3 is just enough to allow the suture to get in. It does not permit the knot to do so.

The long needle 1 is ended with a bifid upper end 4.

A polypropylene suture 7 is separate and contains knots 5, cones

6 and a curved non-cutting small needle 8 at its terminal end similar to the classical silhouette suture.

Figure 2 shows the polypropylene suture 7 which is stretched over the long needle 1 between the curved slit 3 and the bifid upper end 4.

Figure 3 shows how the suture is tied to the curved slit.

SUBSTITUTE SHEET RULE 26 In the first possibility the knot 5 is trapped by the curved slit in the drawing on the left. The second possibility shows a small tie 9 at the end of the suture which is hooked by the curved slit in the middle drawing. The third possibility shows a larger tie 10 which is hooked by the curved slit in the drawing on the right.

Figure 4 shows the classical silhouette suture. The long needle 1 is eight inch long and is made of stainless steel. Its blunt lower end 2 reduces tissue trauma on insertion. A small puncture is required to get the long needle 1 out of the skin of the face after the insertion of the suture through the temporal incision.

The polypropylene suture 7 is 12 inch long and is attached to the upper end of the long needle 1. It has the knots 5 and the cones 6. There are 10 knots and 10 cones. The needle 8 which is attached to the terminal end of the suture 7 is small, half circle and non-cutting.

Claims

1. A modified silhouette facelift surgical suture comprising a long needle which has a curved slit near to its blunt lower end, and a bifid upper end such that a polypropylene suture with cones and knots can be stretched and fixed over the long needle for proper surgical insertion.

2. A modified silhouette facelift surgical suture according to claim 1, in which the curved slit accommodates the suture at its terminal end and does not allow the final knot to pass through it.

3. A modified silhouette facelift surgical suture according to claim 1, in which the bifid upper end fixes the stretched suture tightly in place making the suture ready for proper insertion.

4. A modified silhouette facelift surgical suture according to claim 1, in which the curved slit at the lower end of the needle fixes the terminal end of the suture with either a small tie in anterior position or a larger tie in posterior position as alternatives to the terminal knot.
