Rasp handle adapter

1. A rasp adapter comprising:

a body that defines a body cavity and a trunnion bore;

an adapter trunnion extending from a superior surface of the body; and

a retention element located within the body cavity and secured to the body via a biasing element, the retention element including a knuckle located proximate to and movable into and out of the trunnion bore;

wherein the biasing element is configured to bias the knuckle into the trunnion bore; and

wherein insertion of a rasp trunnion into the trunnion bore causes the knuckle to temporarily move out of the trunnion bore until the knuckle is aligned with a notch in the rasp trunnion.

2. The rasp adapter of claim 1 , wherein the biasing element comprises a spring.

3. The rasp adapter of claim 2 , wherein the spring includes a plurality, of spring legs.

4. The rasp adapter of claim 3 , wherein the plurality of spring legs includes at least one pair of legs joined by an arched portion.

5. The rasp adapter of claim 3 , wherein at least two of the spring legs have different lengths.

6. The rasp adapter of claim 3 , wherein at least one of the spring legs is angled relative to an axis of the trunnion bore.

7. The rasp adapter of claim 2 , wherein the spring comprises a torsional spring.

8. The rasp adapter of claim 2 , wherein the spring comprises a compression spring.

9. The rasp adapter of claim 1 , wherein the knuckle defines a lead in proximate the trunnion bore.

10. The rasp adapter of claim 1 , wherein the body further defines a handle opening.

11. The rasp adapter of claim 10 , wherein the retention element further includes a heal located proximate the handle opening.

12. The rasp adapter of claim 11 , wherein insertion of a handle into the handle opening of the body causes a force to be applied to the heal of the retention element, thereby moving the knuckle of the retention element toward the trunnion bore.

13. A rasp adapter comprising:

a body that defines a body cavity and a trunnion bore;

a trunnion protruding from a superior surface of the body, the trunnion defining at least one trunnion notch; and

a retention element located within the body cavity, the retention element secured to the body via a biasing element and including a knuckle configured to move into and out of the trunnion bore;

wherein the biasing element is configured to bias the knuckle into the trunnion bore; and

wherein movement of the retention element due to a force applied to the knuckle causes movement of the knuckle out of the trunnion bore.

14. The rasp adapter of claim 13 , further comprising a protrusion extending from an inferior surface of the body.

15. The rasp adapter of claim 13 , wherein the body and the retention element are formed as a monolithic component.

16. The rasp adapter of claim 13 , further comprising a stop located proximate the knuckle, the stop configured to limit motion of the retention element.

17. The rasp adapter of claim 13 , wherein a surface of the body cavity defines an arch structure with an apex proximate the knuckle.

18. The rasp adapter of claim 13 , wherein the knuckle defines a lead in proximate the trunnion bore.

19. A rasp adapter comprising:

a body that defines a body cavity, a handle opening, and a trunnion bore; and

a retention element located within the body cavity, the retention element including a knuckle located proximate to and movable into and out of the trunnion bore, wherein movement of the retention element due to a force applied to the knuckle causes movement of the retention element and movement of the knuckle at least partially out of the trunnion bore;

wherein the body and the retention element are formed as a monolithic component.
