1. A mount for temporarily affixing a surgical apparatus to a bony structure comprising:
- a base member having a top face configured to be impacted by an insertion device; and
a plurality of elongated prongs extending downwardly from the base member and configured to engage a bony structure, wherein each of the plurality of elongated prongs are separated a distance from one another, wherein the plurality of elongated prongs are configured to move inwardly toward one another when driven downward into the bony structure,wherein each prong comprises a protrusion disposed substantially inwardly toward a central cavity defined by the plurality of prongs;
wherein the plurality of elongated prongs include a first prong, a second prong, a third prong, and a fourth prong, wherein a first arched portion between the first prong and the second prong has a first distance from the top face, and a second arched portion from the second prong to the third prong has a second distance from the top face, the second distance being greater than the first distance;
further comprising an outer sleeve having a hollow interior configured to engage an outer surface of the base member, and the outer sleeve is configured to rotate in order to compress the plurality of elongated prongs inwardly toward one another.
