tungsten carbide inserts, heavy pattern, 6.0 mm jaws, 7-3/4″ (19.5 cm) Berry Sternal Needle Holder & Wire Twister is a highly versatile instrument that is useful in a vast array of surgical settings. Not only does it serve as a needle holder to aid in suturing during and at the close of surgery but it has other uses as well. The same ability to grip that makes it ideal for use in needle manipulation also makes it ideally suited for twisting wire. Many procedures require the placement of a wire to hold something together or to give some temporary stability while the body heals.
