The non-absorbable suture is a medical suture material used to close wounds. Non-absorbable sutures can remain in the body indefinitely, providing a long-term solution for wound closure.

Nylon sutures, polyester sutures, silk sutures, polypropylene sutures, stainless steel sutures are non-absorbable sutures.

Non-absorbable sutures can provide greater strength and durability than absorbable sutures and are less likely to cause irritation or infection. However, they can be more expensive and difficult to remove, so it is important to consider the specific needs of the procedure before deciding which suture to use.
