Sutures Thread with Needle

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

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

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.

Suture Materials

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.

  1. Hello Richard,

    I didn’t know there was so much difference between the needles especially for just stitching wounds. I guess it makes sense that a different needle will be used for plastic surgery than for working on muscle. I wonder if they still use silk as suture materials?

    Thank you for sharing, that was very interesting.

    • Great question, and thanks for the encouragement! Silk is one of the many materials that are used for suture thread. Other materials include Nylon, Polyester, Polypropylene, etc.

  2. I always knew that surgical procedures had there own science to them. However, I definitely didint know about the different types of suture needles! These things are so exact, it makes me feel a lot safer to know that the suture material is so in depth with its specs. Thanks for sharing!

  3. Hey Richard,

    Thanks for this technical information on Sutures Thread with Needle, I didn’t know about this different materials, it make sense, doctors need precision materials to perform the surgeries. Very interesting.

    Thanks for sharing,


  4. Remarkable and very detailed article! I especially like how you explained the usage of each type of surgical needle. Very informative.
    Thank you Richard

  5. Nice article Richard. Well written and easy to follow even for us non-medical types. You’ve used really appropriate graphics and covered off your content in useful bite sized chunks. Thanks for sharing.
