Surgical instruments including a set of cutting blades for performing an osteotomy
Surgical instruments for performing wedge-shaped osteotomies are disclosed herein. One surgical instrument includes a body including a distal end, a proximal end, and a top surface. The top surface includes a slope extending upward and along a single plane from the distal end to the proximal end. Multiple columns of cutting blades positioned on the top surface and each of the cutting blades includes a respective uniform height that extends vertically along at least a portion of the slope. Another surgical instrument includes a top surface including a flat plane. Multiple columns of cutting blades are positioned on the top surface and the columns of cutting blades are spaced apart and positioned on at least a portion of the top surface. Each cutting blade extends horizontally along the top surface and includes an increasing slope extending upward and along a single plane from the distal end to the proximal end.

8. A surgical instrument, comprising:
a body comprising a distal end, a proximal end, a bottom surface, and a top surface, the top surface including a slope extending upward and along a single plane from the distal end to the proximal end; and
a plurality of cutting blades spaced apart and positioned on the top surface in columns of cutting blades,
wherein:
each of the plurality of cutting blades comprises a cutting portion extending away from the top surface;
each of the plurality of cutting blades extends along at least a portion of the top surface, and
the plurality of cutting blades comprises a uniform height.
9. The surgical instrument of claim 8 , wherein:
the slope defines an angle between the top surface and the bottom surface in the range of 1 degree and 15 degrees.
10. The surgical instrument of claim 8 , wherein:
each cutting blade in the plurality of cutting blades comprises a respective uniform height.
11. The surgical instrument of claim 10 , wherein:
each cutting blade in the plurality of cutting blades comprises a same respective uniform height.
12. The surgical instrument of claim 8 , wherein:
the distal end includes a first horizontal width;
the proximal end includes a second horizontal width; and
the first horizontal width is greater than the second horizontal width such that the body includes a width that tapers from the distal end to the proximal end.
13. The surgical instrument of claim 8 , wherein:
the proximal end and the distal end include a same horizontal width such that the body includes a uniform width.
14. The surgical instrument of claim 8 , wherein:
the plurality of cutting blades includes a quantity of cutting blades in the range of two cutting blades to 40 cutting blades.
15. A surgical instrument, comprising:
a body comprising a distal end, a proximal end, a bottom surface, and a top surface; and
a plurality of cutting blades spaced apart and positioned on the top surface in columns of cutting blades,
wherein:
each of the plurality of cutting blades extends vertically along the portion of the top surface, and
each cutting blade in the plurality of cutting blades comprises a respective increasing height extending from the distal end to the proximal end such that a first height toward the proximal end is greater than a second height at the distal end of each cutting blade.
