A surgical suture, also known as a stitch or stitches, is a medical device used to hold body tissues together and approximate wound edges after an injury or surgery. . Application generally involves using a needle with an attached length
Needles have different shapes (e.g. j shape, ½ circle, straight) and cutting edges (tapered - round, conventional cutting - triangular) depending on the application and areas of the suture. [21] Sutures can be categorized based on different sizes (e.g.#5-#11, higher numbers represent larger suture diameter) and types (absorbable and ...
Blunt-tip or tapered-tip suture needles can be used to sew muscle and fascia. Though they are more expensive than sharp-tipped needles, this cost is balanced by the reduction in injuries, which are expensive to treat. [7] [20] [21] Sharp-tipped needles cause 51–77% of surgical needlestick injuries. [22]
A standard general surgical needle holder, with a ratchet handle lock. Two specialty needle holders, Mathieu needle holder (above) and Castroviejo needle holder (below). A needle holder, also called needle driver or needle forceps, is a surgical instrument similar to a hemostat, used by doctors and surgeons to hold and push a suturing needle when performing wound closure, ligation and other ...
It is performed by treating the area with an antiseptic, such as iodine-based solution, and then making a small incision to puncture the skin using a sterile instrument such as a sharp needle or a pointed scalpel. This allows the pus to escape by draining out through the incision.
There are several methods that can be implemented to achieve primary closure of a wound, including suture, staples, skin adhesive, and surgical strips. Suture is the most frequently used for closure. [27] There are many types of suture, but broadly they can be categorized as absorbable vs non-absorbable and synthetic vs natural.
The needle is entered 3 mm (0.12 in) from the lateral edge of the future bleb site and 3–4 mm (0.12–0.16 in) away from the limbus. The 8-0 nylon suture is taken under the scleral flap. Once this happens, the suture is reversed and the needle is passed through the conjunctiva from the inside towards the outside position.
At the end of the running suture line, clips can be placed across the suture tail. Barbed suture is a knotless surgical suture that has a pattern of barbs on its surface. These barbs lock the suture into the tissue, eliminating the tying of knots. Barbed sutures are typically used in cosmetic and reconstructive surgery.
