Needles
The three major parts of a surgical needle are the tip (or point), the body, and the shank.
· The most common body configuration in dermatological surgery is curved, with a radius of between 1/4 and 5/8 of a circle.
· The tip is usually triangular with either conventional cutting (sharp edge on the inside arc) or reverse cutting (sharp edge on the outside arc). The more the tip is honed, the sharper and more expensive the needle.
· A reverse cutting needle provides less chance of the tissue tearing during suturing. A round needle with tapered tip is the least likely to cause tissue tearing, and is primarily used for suturing fascia, muscle, and aponeuroses.
· The body may be flattened to facilitate needle-holder grasp, and limit twisting during placement.
