## Abstract

A surgical blade having an attachment base positioned at a proximal end and a wedge-shaped blade. The wedge-shaped blade includes a cutting tip having a first plurality of cutting teeth, which define a cutting edge along the distal end for starting an osteotomy. The wedge-shaped blade includes a second plurality of teeth positioned along rows. Each row is positioned at offset planes from adjacent rows along the wedge-shaped blade.

## Claims

### Claim 1

A surgical blade comprising:
a wedge-shaped blade extending between a proximal end and a distal end, the wedge-shaped blade including:
a cutting tip having a first plurality of cutting teeth, which define a cutting edge along the distal end for starting an osteotomy,
a second plurality of teeth positioned along rows, each row positioned at offset planes from adjacent rows along the wedge-shaped blade, and
a surface defining the proximal end, wherein the surface is curved and does not include any teeth; and
an attachment base that extends between a base proximal end and a base distal end, that is flat, and that includes multiple openings that are oval-shaped, wherein the base distal end adjoins the proximal end of the wedge-shaped blade.

### Claim 2 (depends on 1)

The surgical blade of claim 1, further comprising a neck portion intermediate the wedge-shaped blade and the attachment base.

### Claim 3 (depends on 1)

The surgical blade of claim 1, wherein the wedge-shaped blade includes a cutting slope along which the second plurality of teeth is positioned with each row of teeth elevated above the cutting tip.

### Claim 4 (depends on 1)

The surgical blade of claim 1, wherein the wedge-shaped blade comprises steel.

### Claim 5 (depends on 1)

The surgical blade of claim 1, wherein the wedge-shaped blade comprises stainless steel.

### Claim 6 (depends on 1)

The surgical blade of claim 1, wherein the wedge-shaped blade does not include teeth on at least three of its sides.

### Claim 7 (depends on 1)

The surgical blade of claim 1, wherein the wedge-shaped blade is flat on four sides and accommodates the second plurality of teeth on a fifth side and the cutting tip on a sixth side.

### Claim 8 (depends on 1)

The surgical blade of claim 1, wherein the wedge-shaped blade includes a bottom plane, wherein the offset planes are parallel to the bottom plane.

### Claim 9 (depends on 1)

The surgical blade of claim 1, wherein the rows include eight rows.

### Claim 10 (depends on 1)

The surgical blade of claim 1, wherein the first plurality of teeth and the second plurality of teeth include triangle-shaped teeth.

### Claim 11 (depends on 1)

The surgical blade of claim 1, wherein the first plurality of teeth and the second plurality of teeth decrease in width as said teeth extend towards the distal end.

### Claim 12 (depends on 1)

The surgical blade of claim 1, wherein the first plurality of teeth and the second plurality of teeth have tips that are positioned along a radius.

### Claim 13 (depends on 1)

The surgical blade of claim 1, wherein each row of the second plurality of teeth is positioned along a different radius than adjacent rows.

### Claim 14 (depends on 1)

The surgical blade of claim 1, wherein each row includes twelve teeth.

### Claim 15 (depends on 1)

The surgical blade of claim 1, wherein the wedge-shaped blade includes a cutting slope along which the rows are positioned.

### Claim 16 (depends on 15)

The surgical blade of claim 15, wherein the cutting slope is a linear slope.
