The ideal surgical needle is made of high quality stainless steel, as slim as possible without compromising strength, stable in the grasp of a needle holder, able to carry suture material through tissue with minimal trauma, sharp enough to penetrate tissue with minimal resistance, rigid enough to resist bending but not break, sterile, and corrosion-resistant.
Surgical Needles may be classified by their point geometry.
Examples include:
Taper (needle body is round and tapers smoothly to a point), cutting (needle body is triangular and has a sharpened cutting edge on the inside curve), reverse cutting (cutting edge on the outside), trocar point or tapercut (needle body is round and tapered, but ends in a small triangular cutting point), blunt points for sewing friable tissues, side cutting or spatula points (flat on top and bottom with a cutting edge along the front to one side) for eye surgery e.t.c.
