Needles- Most common 3/8 circle, triangular-shaped needle point; needle composed of three parts: tip, body and shank (latter where suture material attached); needle driver grasps body of needle
- Reverse cutting needles have advantage of minimizing risk of tearing through wound edge during suture placement
- Surgical yield of needle: amount of angular deformation occurring before permanent deformation of needle
- Ultimate moment of needle: measure of maximum strength by bending needle to 90°
- Types of needles (per one manufacturer): Ethicon P (plastic), PS (plastic skin), PC (precision cosmetic), and FS (for skin)
