Wound closure is the process of bringing the edges of a wound together to promote healing. It can be done with stitches, staples, adhesive strips, or skin glue. The type of wound closure that is used will depend on the size and location of the wound. There are four main types of wound closure: 1) Sutures: Sutures are small, thread-like stitches that are used to close wounds. They can be made of different materials, such as nylon, silk, or absorbable sutures. Sutures are usually removed after 7-10 days. 2) Staples: Staples are small, metal fasteners that are used to close wounds. They are often used on larger wounds or wounds that are in difficult-to-reach areas. Staples are usually removed after 5-7 days. 3) Clip Appliers: Clip appliers are medical devices used to close wounds. They work by applying small, metal staples to the skin, which hold the edges of the wound together. Clip appliers are often used on larger wounds or wounds that are in difficult-to-reach areas. 4) Clip Removers: Clip removers are medical devices used to remove skin staples. They work by applying pressure to the staple, which loosens it and allows it to be removed. Clip removers are often used on wounds that have been closed with staples.
