SUTURES AND LIGATURES

In surgery all tissue layers are cut to reach the required organ. On closure all these layers must be stitched back in position accurately to its opposing layer to provide anatomical continuity which was interrupted while opening up the body. Surgeons have made use of sutures and ligatures for achieving closure the following are some available techniques for skin closure.

1.      Needle and suture

2.      Metal ligature

3.      Skin clips

4.      Staples

5.      Adhesive closure

         A suture or a stitch holds cut tissue layers or structure together to help the process of healing.

         A ligature or metal ligature is the use of the material to encircle a cut end of a blood vessel so as to control bleeding. Staples have been used to anastemose hollow organs and vessels. Suture can be:

1.      Absorbable or

2.      Nonabsorbable

         And both these varieties may be made of either natural or synthetic fiber.

NEEDLES

•       These can be with an eye where thread has to be passed through so that two strands pass through the tissues causing trauma.

•       The same is true of spring eye needles.

•       Shapes of needles vary from quarter circle to straight and the shape of the tip of the needle shown in Figures above.

•       A traumatic needle come with the suture material (single strong) attached to the needle .

•           These are presterilized and come in double wraps
