Abstract
A plate holding drill guide or 'trocar' is disclosed including a member having a channel with an internal diameter. A cannulated holding member having prongs is disposed, at least in part, within the channel. A cannula extends through the prongs. At one end, the prongs are flanged outward. The flanged portion has an external diameter which is greater than the internal diameter of the channel. The sliding member is displaceable over the flanged portion of the prongs. When an annular frame of a bone plate is disposed between the prongs and the sliding member is moved toward the flanged portion, the prongs grip the frame. A drill may be guided between the prongs through the cannula. A method is disclosed for holding a bone plate. An annular frame of the bone plate is positioned between prongs and aligned with a cannula extending between the prongs. A member is displaced along the prongs. The prongs are deflected inward, gripping the frame.
