SCISSORS

The final instruments necessary for placing sutures are suture scissors (Fig. 6-26). Suture scissors usually have relatively long handles and thumb and finger rings. They are held in the same way as the needle holder. The suture scissors usually have short cutting edges because their sale purpose is to cut sutures (Fig. 6-27). The most commonly used suture scissors are the Dean scissors. These have slightly curved handles and serrated blades that make cutting sutures easier.

An additional type of scissors is designed for soft tissue.The two major types of tissue scissors a.re (1) the Iris scissors and (2) the Metzenbaum scissors (Fig. 6-28). The Iris scissors are small, sharp-pointed delicate tools used for fine work. The Metzenbaum scissors are blunt-nosed scissors used for undermining soft tissue, as well as for cutting. Tissue scissors such as the Iris or Metzenbaum scissor should not be used to cut sutures, because the suture material will dull the edges of the blades and make them less effective for cutting tissue. The exception is when removing very fine sutures placed in skin incisions in the face. Scissors with thin pointed tips such as an Iris may be useful.

Soft tissue scissors are of two designs: Iris scissors (top) are small, sharp-pointed scissors. Metzenbaum scissors (bottom) are longer, delicate, blunt-nosed scissors.
