When it comes to surgical suturing during a procedure, the types of surgical sutures are critical. The factors of the selection of needles are the size and the purpose, such as cutting through tissue or close the wound right away. What are sutures, and what are the different varieties and types of needles and sutures?
Tapered needles are round-bodied needles, and each one is tapered and doesn’t have a cutting edge. Therefore, they are usually used for closing soft tissues at bowels, muscles, or fascia areas and other soft tissues below the surface of the skin.
This type of needle is specially designed for separating tissue fibers rather than cutting them. After inserting 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 sizes are made according to the type of tissue and wound closure. For example, a thin thread is used for repairing bowel tissues while a thick thread is used for suturing muscle.
Cutting needles are used for normal wound closure and are often used for ophthalmic and plastic surgery on ligaments and tough skin tissue. The edge of the needle is triangular and contains a sharp cutting tip. However, when not working with tough tissues, most medical practitioners prefer the reverse cutting needle. The difference between the two is quite apparent. Standard cutting needles have edges on the inside, while a reverse cutting needles have edges on the outside.
There is a wide selection of suture materials today. Many factors contribute to ideal suture material. None of the suture materials available today fully meet all these criteria, and the specific material must be chosen based on the operational requirements for a particular surgical situation.
Suture materials consist of monofilaments and multifilaments. Multifilaments have several strands that are braided together. They are easier to handle and provide better knot security. However, they are easy to hide micro-organisms between strands and are hence prone to serious infection. Monofilaments are less likely to cause infection but are challenging to handle and have relatively poor knot security.
