Abstract

A surgical saw blade is disclosed for improved resection and cutting of tissue. The surgical saw blade may include a front side, an opposite back side, a top side, an opposite bottom side, a right side, and an opposite left side. The surgical saw blade may further include a cutting tooth extending from the back side and having a cutting edge oriented toward one of the right side and the left side, the cutting tooth associated with an aperture through the saw blade between the front and back sides. The back side may be a single direction cutting side and the front, top, bottom, right, and left sides may be non-cutting sides. The surgical saw blade may further include a saw connection feature near the bottom side.

First claim

The invention claimed is:

1. A surgical saw blade comprising:
a front side, an opposite back side, a top side, an opposite bottom side, a right side, and an opposite left side;
a cutting tooth extending from the back side and having a cutting edge oriented toward one of the right side and the left side, the cutting tooth associated with an aperture through the saw blade between the front and back sides;
wherein the back side is a single direction cutting side and the front, top, bottom, right, and left sides are non-cutting sides;
a saw connection feature near the bottom side, and
one or more markings on the back side, the one or more markings configured to indicate that the back side is a cutting side, wherein the one or more of the markings comprises a direction marker that indicates which direction the single direction cutting side cuts in.

2. The surgical saw blade of claim 1 , wherein an aperture width for the aperture is 70% to 115% of a height for the cutting tooth.

3. The surgical saw blade of claim 1 , wherein the front side and the opposite back side are the broadest sides of the saw blade.

4. The surgical saw blade of claim 1 , wherein the aperture is rectangular and comprises two parallel sides, an arcuate side that connects the two parallel sides and an open side in communication with the cutting edge of the tooth.

5. The surgical saw blade of claim 1 , wherein the cutting edge is one of arcuate and straight.

6. The surgical saw blade of claim 1 , wherein the cutting edge has a base and extends from the base in a distal direction to a cutting edge that faces the one of the right side and the left side, such that the distal direction is perpendicular to the one of the right side and the left side.

7. An oscillating surgical saw blade comprising:
a front side, an opposite back side, a top side, an opposite bottom side, a right side, and an opposite left side;
a plurality of cutting teeth connected to the back side and each of the cutting teeth having a cutting edge oriented toward a common side of the oscillating saw blade, each of the cutting teeth adjacent to an aperture through the saw blade between the front and back sides;
wherein the front, top, bottom, right, and left sides are non-cutting sides; and
an oscillating surgical saw connection feature near the bottom side, connectable to an oscillating surgical driver of an oscillating surgical saw,
wherein the cutting edge comprises a bevel comprising opposite corner bevels and one or more front bevels.

8. The oscillating surgical saw blade of claim 7 , wherein an aperture width for the aperture of each of the plurality of cutting teeth is 70% to 115% of a height for the adjacent of the cutting teeth.

9. The oscillating surgical saw blade of claim 7 , wherein the common side comprises one of the right side and the left side.

10. The oscillating surgical saw blade of claim 7 , wherein each of the cutting teeth comprises:
a base;
the cutting edge;
a first side between the base and the cutting edge, the first side defining a first slot between the first side and the saw blade;
a second side between the base and the cutting edge, the second side defining a second slot between the second side and the saw blade;
wherein one end of the first slot comprises a first scalloped edge and the opposite end of the first slot connects to the aperture; and
wherein one end of the second slot comprises a second scalloped edge and the opposite end of the second slot connects to the aperture.

11. The oscillating surgical saw blade of claim 10 , wherein the first side comprises a first side bevel and second side comprises a second side bevel.

12. The oscillating surgical saw blade of claim 7 , wherein the plurality of cutting teeth are organized into a plurality of rows and columns.

13. The oscillating surgical saw blade of claim 12 , wherein each row of cutting teeth aligns with apertures of at least one adjacent row of cutting teeth.

14. An oscillating surgical saw blade comprising:
a front side, an opposite back side, a top side, an opposite bottom side, a right side that extends from the top side to the bottom side, and an opposite left side that extends from the top side to the bottom side;
a set of cutting teeth organized into rows and columns;
wherein the cutting teeth extend from the back side and each of the cutting teeth has a base and extends from the base in a distal direction to a cutting edge oriented toward one of the right side and the left side, such that the distal direction is perpendicular to the one of the right side and the left side, each of the cutting teeth associated with a rectangular aperture through the saw blade between the front and back sides; and
an oscillating saw connection feature near the bottom side, connectable to an oscillating surgical driver of an oscillating surgical saw.

15. The oscillating surgical saw blade of claim 14 , wherein the cutting teeth in each column are aligned vertically and the cutting teeth in each row are aligned horizontally.

16. The oscillating surgical saw blade of claim 14 , wherein each of the cutting teeth comprises:
a base;
the cutting edge;
a first side between the base and the cutting edge, the first side defining a first slot between the first side and the saw blade; and
a second side between the base and the cutting edge, the second side defining a second slot between the second side and the saw blade.

17. The oscillating surgical saw blade of claim 16 , wherein first side and the second side are parallel to each other.

18. The oscillating surgical saw blade of claim 16 , wherein:
one end of the first slot comprises a first scalloped edge and the opposite end of the first slot connects to the aperture;
one end of the second slot comprises a second scalloped edge and the opposite end of the second slot connects to the aperture; and
the first side comprises a first side bevel and second side comprises a second side bevel.

19. The oscillating surgical saw blade of claim 14 , wherein each cutting edge comprises a bevel comprising opposite corner bevels and one or more front bevels.

20. The oscillating surgical saw blade of claim 14 , wherein an aperture width for each rectangular aperture is 70% to 115% of a height for each of the cutting teeth.
