Claim:
1. A device for preparing a surgical site comprising: a retractable tool; and an actuator connected to the retractable tool, wherein the retractable tool comprises a distal member and a proximal member, wherein a distal side of the distal member is fixed in a longitudinal direction and pivotable at a point of rotation, wherein a proximal side of the proximal member is pivotably connected to the actuator, wherein in a retracted position the distal member is pivotably connected to the proximal member at a pivot axis longitudinally in between the point of rotation and the proximal side of the proximal member, wherein in the retracted position the distal member and the proximal member extend generally along the longitudinal direction, wherein, from the retracted position, moving the actuator in a distal direction pushes the proximal member and the distal member such that the proximal member pivots with respect to the actuator and the distal member, the distal member pivots with respect to the proximal member and the point of rotation, and the proximal member and the distal member move laterally outward with respect to the longitudinal direction toward an extended position, and wherein at least one of the distal member and the proximal member defines a through-opening that extends transverse to the longitudinal direction and allows passage of bone and tissue when the proximal member and the distal member move laterally inward from the extended position to the retracted position.
