    • A device for holding a surgical instrument having a body, an instrument engagement device and a knob. The body has a proximal end, a distal end and a passageway positioned through the body. The instrument engagement device is positioned in the passageway and has at least two prongs moveable relative to each other to hold the surgical instrument therebetween. The knob is preferably positioned on the proximal end of the body and operatively associated with the at least two prongs so that movement of the knob causes movement of the prongs. The prongs may further include at least one ridge for engaging at least one slot on the surgical instrument. The knob may further comprise a cap at its proximal end positioned and designed for impact, for example, by a hammer, to facilitate movement of the surgical instrument into the patient. The knob may also include a locking mechanism to fix the position of the prongs.
