When looking for suture needles, you have plenty of choices. Straight suture needles are usually used when tissue is easily accessible. They are useful for skin closure or microsurgical procedures. Half-Curved needles are usually used in laparoscopic surgeries. 1/4 circle needles have a shallow curvature and used on easily accessible convex surfaces. 3/8 Circle needles are best used in confined locations. 5/8 needles are ideal for deep confined holes. Tapered suture needles have a round bodied needle with a blunt point, they are tapered and have no cutting edge. Tapered needles were designed to separate tissue rather than cutting. Cutting suture needles are used for general skin closure. Some surgeons prefer their subtype reverse cutting edge because the cutting edge is on the outer curvature.
