Rasp tool

A rasp tool for preparing an implantation site, the tool comprising:

• a first arm comprising a proximal end and a distal end;
• a second arm comprising a proximal end and a distal end, wherein the first arm and the second arm are pivotally connected to one another;
• a first wing extending from the distal end of the first arm, the first wing comprising:
• a conical tip positioned at a distal end of the first wing and configured to ease insertion into the implantation site;
• and
• a cutout defined along a first side of the first wing;
• and
• a second wing extending from the distal end of the second arm, the second wing comprising a tapered tip positioned at a distal end of the second wing and configured for mating with the cutout;
• wherein the first wing and the second wing are configured to move between a closed position and an open position by pivoting the first arm and the second arm;
• wherein the second wing is received at least partially within the cutout when the first wing and the second wing are in the closed position;
• wherein the second wing is positioned entirely outside of the cutout when the first wing and the second wing are in the open position;
• wherein the first wing has a first length from a proximal end of the first wing to the distal end of the first wing;
• wherein the second wing has a second length from a proximal end of the second wing to the distal end of the second wing;
• and
• wherein the first length is greater than the second length.

• a first arm comprising a proximal end and a distal end;
• a second arm comprising a proximal end and a distal end, wherein the first arm and the second arm are pivotally connected to one another;
• a first wing extending from the distal end of the first arm and rigidly attached to the first arm, the first wing comprising a conical tip positioned at a distal end of the first wing and configured to ease insertion into the implantation site;
• and
• a second wing extending from the distal end of the second arm and rigidly attached to the second arm, the second wing comprising a tapered tip positioned at a distal end of the second wing;
• wherein the first wing has a first length from a proximal end of the first wing to the distal end of the first wing, wherein the second wing has a second length from a proximal end of the second wing to the distal end of the second wing, and wherein the first length is greater than the second length.
