In wound suturing, the most important thing to note after choosing the type of suture is the type of needle that is to be used in performing the surgical procedure. The factors that are considered for the selection of the needle is the size and the purpose i.e. for sifting through tissue or mending it straight away.
Tapered needles for instance are generally used inside the body such as on the bowel, muscle, or fascia places where the tissue is easily accessible and therefore pierced just as easily too. Cutting needles on the other hand are used for very rough tissue ligaments and skin.
The appropriate size of the needle is a very important point as already explained. There are many different sizes and sub-types of needles that are more commonly used for performing wound suturing, and other surgical procedures.
Tapered Suture Needles
This type of suturing needle is also called a round bodied needle due to its shape and blunt point. The needle has a tapered and no cutting edge; therefore, it is generally used for closing soft tissue such as gastrointestinal, vascular, fascia, and other soft tissue that is found below the skin’s surface.
This type of needle are especially designed for separating tissue fibers, rather than cut them. After inserting of the needle, the tissue closes tightly around the suture material, which in turn forms a sort of leak proof barrier which prevents outside contaminants from entering the wound.
Different wire diameters are used in every round bodied needle that is manufactured, and which is made according to the type of tissue and wound to be sutured. For example, fine wire diameters are used to repair bowel tissues, whereas for suturing muscle a heavier wire diameter is used.
TP: Is used to close fascia during abdominal surgery
CT: Is used to close the joint space or deep layers of tissue after general surgery
CT2: Is often used on closing of uterus
SH: Is used to close bowel or tissue layers after breast surgery
CV: Used for nerve repair and delicate vessels.
Cutting Suture Needles
These type of suturing needles is used for general closure of skin, subcutaneous tissue etc, and is sometimes also used for ophthalmic surgery and plastic surgery. The point if the needle is triangular, and with a cutting edge. Other than the conventional cutting needle, most surgeons commonly prefer its sub-type i.e. the reverse cutting needle except for tough tissue. The difference between the two types is the cutting edge of conventional needle is on the inner curvature, as opposed to the reverse cutting edge needle which has it on the outer curvature.
FSLX: Used for large skin closure, when a lot of tension is present
FSL: Is used for the procedures that need a higher tension closure
FS2: Is used for common closing of skin
P3: Is used for closing of small incisions, such as in facial reconstructive surgery and hand surgery
