SURGICAL INSTRUMENTS 11 Needle Holders






Needle Holders
Needle holders are modified box-lock forceps designed to hold curved needles. The surgeon should thus be able to manipulate the needle with ease during suturing near the surface (short needle holders) or at a depth (long).
         Since the function of needle holders is to grasp needles the instruments look like artery forceps:
1.      Serration at the tips to prevent slipping of needle.
2.      Shafts with rings for thumb and fingers.
3.      Locking device.
         Fine needle holders are damaged by large needles and small needles are damaged by large needle holders. The varieties in use are:
•       Mayo needle holder (Fig. 8.73)
•       Gillies needle holder (Fig. 8.74)
•       Naunton Morgan needle holder (Fig. 8.75)
•       Kilner needle holder (Fig. 8.76)
•       Mayo-Hegar needle holder (Fig. 8.77)
•       Microvascular (Doious) needle holder (Fig. 8.78).
