LIGATURE AND SUTURE MATERIALS 1
Surgical procedures require superficial tissue layers to be cut, to reach the required Organ.
-On closure at the end of the procedure, all these cut layers, must be stitched back in position, accurately to its opposing layer.
-Anatomical continuity, interrupted while opening up the body needs to be restored.
WHAT ARE THE SUTURES AND LIGATURES IN USE?
Surgeons have made use of sutures for achieving closure.
The following are some available techniques for skin closure.
1. Needle and suture
2. Skin clips
3. Staples
4. Adhesive closure
SUTURE
A suture or a stitch holds cut tissue layers, or structure
Together, this helps the process of healing.
LIGATURE
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 anastomose(join) hollow organs, and vassal
Suture can be:-
1 Absorbable or
2 Nonabsorbable
And both these varieties may be made of either natural or
synthetic fibre have to be used with a needle.
WHAT ARE THE NEEDLES AVAILABLE?
These are pointed metal instruments with an eye where thread has to be passed through so that two strands pass through the tissues causing little trauma.
* The same is true of sprng eye needles Fig.3.4
* Shapes of needles are shown in fig. and vary from quarter circle
to straight and the shape of the tip of the needle Fig.3.1A to D
* Atraumitic needle come with the suture materiel (single
strand) attached to the needle fig.3.2
These are pre-sterilized and come in double wraps. Fig 3.3
