Abstract

A system and method for debriding callus foot tissue is disclosed. The method may include applying a chemical peel to callus foot tissue and using a debriding tool to remove the chemically treated callus foot tissue. In certain embodiment, the method may include preparing the chemical peel, including customizing at least one attribute of the chemical peel based on at least one attribute of the callus foot tissue. The system may include a debriding tool having a cutting head that may be easily removed for cleaning or replacement.

Claims

1. A debriding tool defining axial, radial, and circumferential directions, the tool comprising:

a shaft extending in the axial direction and having a first end and a second end opposite the first end in the axial direction;

a flange connected to the second end of the shaft to extend in the radial direction therefrom;

the flange defining at least one aperture extending in the axial direction therethrough;

the flange having a circumference formed to including at least one spiraling groove; and

a cutting head comprising

a convex end cap,

a cylindrical side wall,

the convex end cap comprising a plurality of burrs,

the cylindrical side wall extending from a perimeter of the convex end cap to cover the circumference of the flange, and

the cylindrical side wall comprising at least one extension extending to engage the at least one spiraling groove to secure the cutting head to the flange.

2. The tool of claim 1, wherein the cylindrical side wall is devoid of burrs.

3. The tool of claim 2, wherein the at least one extension comprises a dimple formed in the cylindrical side wall.

4. The tool of claim 2, wherein the at least one spiraling groove comprises a first spiraling groove, a second spiraling groove, and a third spiraling groove uniformly distributed about the circumference of the flange.

5. The tool of claim 4, wherein the at least one extension comprises a first dimple, second dimple, and third dimple formed in the cylindrical side wall to be uniformly distributed thereon.

6. The tool of claim 5, wherein the first, second, and third extensions engage the first, second, and third spiraling grooves, respectively.

7. The tool of claim 1, wherein the shaft and flange are formed together as a monolithic, seamless unit.

8. The tool of claim 1, wherein the at least one aperture comprises three circular apertures extending in the axial direction through the flange.

9. The tool of claim 1, wherein the cutting head is selectively removable from the flange via rotation in a first direction about an axis extending in the axial direction.

10. A debriding tool defining axial, radial, and circumferential directions, the tool comprising:

a shaft extending in the axial direction and having a first end and a second end opposite the first end in the axial direction;

a flange connected to the second end of the shaft to extend in the radial direction therefrom;

the flange having a circumference and defining at least one aperture extending in the axial direction therethrough;

a cutting head comprising

a convex end cap comprising a plurality of burrs,

a cylindrical side wall devoid of burrs, and

the cylindrical side wall extending from a perimeter of the convex end cap to cover and engage the circumference of the flange; and

the cutting head being selectively removable from the flange via rotation in a first direction about an axis extending in the axial direction.

11. The tool of claim 10, wherein the cutting head further comprises at least one dimple formed in the cylindrical side wall.

12. The tool of claim 11, wherein the flange further comprises at least one spiraling groove formed in the circumference.

13. The tool of claim 12, wherein the at least one dimple engages the at least one groove to removably secure the cutting head to the flange.

14. The tool of claim 13, wherein the at least one spiraling groove comprises a first spiraling groove, a second spiraling groove, and a third spiraling groove uniformly distributed about the circumference of the flange.

15. The tool of claim 14, wherein the at least one dimple comprises a first dimple, second dimple, and third dimple formed in the cylindrical side wall to be uniformly distributed thereon.

16. The tool of claim 15, wherein the first, second, and third extensions engage the first, second, and third spiraling grooves, respectively.

17. The tool of claim 10, wherein the at least one aperture comprises three circular apertures extending in the axial direction through the flange.
