This chapter discusses the type of needles that are used. A surgical needle can be identified by three parts: the eye, the shaft, and the point. The needles with an eye may be used more than once, but of course must be examined after use for damage and to inspect the sharpness. The threaded needle shows the short length, that is, one third of the whole length of the suture material. The most common shapes are straight, curved, or half circle but many other varied shapes are available. The point of the surgical needle can be triangular, taper pointed, or trocar. It is important that the theatre nurse gradually learns to recognize the various types of needle used in her particular place of work. When using a needle holder, the needle should be gripped about one third of the way along the needle shaft from the eye end, and grasped only at the tip of the needle holder. The size of the wound and the position that the surgeon is operating also determines the size of the needle. |
