View Edit Delete	CES-16	In the illustrated embodiment, the cutting teeth 130 extend from the back side 104 and from no other side of the surgical saw blade 100. Consequently, the back side 104 is a single direction cutting side. A single direction cutting side is a side of a structure that is configured to cut tissue, but generally cuts the tissue when the structure moves in a single direction and does not cut, or at least does not cut as effectively, in other directions. A single direction cutting side may also be referred to as a unidirectional cutting side, a one direction cutting side, or the like.	50	Added by DJM 9 2021	9/2/21, 12:00 AM
View Edit Delete	CES-16	In one embodiment, the cutting tooth 130 may extend from the back side 104. In one embodiment, each cutting tooth 130 includes a cutting edge 132 oriented, or directed, toward one of the right side 110 and the left side 112. Having the cutting edge 132 of each cutting tooth 130 directed towards a single side, either a right side 110 or a left side 112 means that the cutting teeth 130 will cut in a single direction. If the cutting edge 132 of each cutting tooth 130 is directed towards the right side 110, the cutting teeth 130 will cut when the cutting teeth 130 are moved in the direction of the right side 110. If the cutting edge 132 of each cutting tooth 130 is directed towards the left side 112, the cutting teeth 130 will cut when the cutting teeth 130 are moved in the direction of the left side 112.	49	Added by DJM 9 2021	9/2/21, 12:00 AM

FIGS. 17-18 illustrate details of an aperture 220, cutting tooth 230, cutting edge 232, and a bevel 234.	82	Added by DJM 9 2021	9/2/21, 12:00 AM
View Edit Delete	CES-16	FIG. 29 illustrates two different types of one or more markings 310 that may be used in various embodiments. As illustrated, in one embodiment, marking 310a is a slot shape with a cross-hatching fill. Alternatively, or in addition, a marking 310b may be used. The marking 310b may include text in a language of the intended user that states that the side with the marking 310b is the cutting side. In the illustrated embodiment, the one or more markings 310 are applied to the back side 104 because the back side 104 is the cutting side. More specifically, in this embodiment, the back side 104 is a single direction cutting side. The one or more markings 310 may be printed on the surgical saw blade 300 or etched on using laser techniques.	93	Added by DJM 9 2021	9/2/21, 12:00 AM
View Edit Delete	CES-16	In particular, the surgical saw blade 300 may include one or more markings 310 and/or one or more direction markers 320. Marking 310 may be a symbol, shape, logo, set of letters or words, or any other indicia to indicate to a user that the side that includes the marking 310 is a cutting side or a single direction cutting side. The one or more markings 310 and/or one or more direction markers 320 may serve to quickly indicate to a user which side is the cutting side. This can help the user in determining how to orient the surgical saw blade 300 and/or how to install the surgical saw blade 300 on a powered handpiece (saw), handle, etc.	92	Added by DJM 9 2021	9/2/21, 12:00 AM
View Edit Delete	CES-16	FIG. 29 is a back view of a surgical saw blade 300, according to one embodiment. The surgical saw blade 300 may have structures, features, functions, operations, and a configuration similar to that of the surgical saw blade 100 or oscillating surgical saw blade 200 described above. Where these structures are substantially the same, like numerals are used to identify the corresponding parts. In the illustrated embodiment, the surgical saw blade 300 includes one or more features that other embodiments may not include.	91	Added by DJM 9 2021	9/2/21, 12:00 AM
View Edit Delete	CES-16	FIG. 28 illustrates a cross-sectional view of the cutting tooth 230, taken along section line 28-28 of FIG. 24, according to one embodiment. FIG. 28 illustrates details of one embodiment of the aperture 220, cutting tooth 230, and one or more front bevels 234.	90	Added by DJM 9 2021	9/2/21, 12:00 AM
View Edit Delete	CES-16	FIG. 27 illustrates a cross-sectional view of the cutting tooth 230, taken along section line 27-27 of FIG. 21, according to one embodiment. In the illustrated embodiment, the cutting edge 232 includes a face 250. In this embodiment, the face 250 is flat and connects to a bottom surface of the cutting tooth 230 at a right angle and to the bevel 234 at an angle greater than 90 degrees.	89	Added by DJM 9 2021	9/2/21, 12:00 AM
View Edit Delete	CES-16	While the saw blades 100, 200 are shown with rectilinear arrays of cutting teeth 130, 230, in other examples the teeth may be positioned in any array configuration. Some examples include arcuate, spiral, or other polynomial. In one example, the teeth may be arranged along arcuate paths that are all concentric with the center point of saw blade oscillation, optionally including the tooth offset discussed above.	88	Added by DJM 9 2021	9/2/21, 12:00 AM
View Edit Delete	CES-16	The oscillating surgical saw blade 200 is designed for use with an oscillating saw that sweeps the saw blade 200 side to side along an arcuate path 270 (FIG. 21). When the saw blade 200 is actuated in this way, the cutting teeth 230 cut bone, cartilage, or other hard or soft tissues next to or against the back side 204 when the saw blade 200 sweeps toward the left side 212. The cutting teeth 230 do not cut when the oscillating surgical saw blade 200 sweeps toward the right side 210, nor does the saw blade 200 cut tissues that are next to, or against the front, right, and/or left side 202, 210, 212. The non-overlapping pattern of cutting teeth 230 may limit bone removal while the saw blade 200 is actuated while being held in one location; moving the saw blade 200 to a different location may permit additional bone removal. The back side 204 may be referred to as a cutting side of the saw blade 200, and the front, right, and/or left side 202, 210, 212 may be referred to as a non-cutting side.	87	Added by DJM 9 2021	9/2/21, 12:00 AM
View Edit Delete	CES-16	Referring to FIGs. 21 and 25, the cutting tooth 230 inside the detail circle 25 is offset away from the top (free end) of the oscillating surgical saw blade 200 relative to the top cutting tooth in the other row; the offset may be equal to the width of the tooth. Each cutting tooth 230 may be angled or bent so that the free end (the cutting edge 232) of the cutting tooth 230 protrudes outwardly from the remainder of the saw blade 200. The cutting teeth 230 are shown protruding outwardly from the back side 204. Each cutting tooth 230 may include one or more bevels 234 along the front side of the tooth, which may sharpen the tooth for cutting along the back side.	86	Added by DJM 9 2021	9/2/21, 12:00 AM
View Edit Delete	CES-16	Referring to FIGS. 25-26, the aperture width 222 may be a percentage of the cutting tooth height 224 of an adjacent cutting tooth 230. The percentage may be 70% to 115%. In some embodiments, the percentage may be 75% ± 5%, 80% ± 5%, 85% ± 5%, 90% ± 5%, 95% ± 5%, 100% ± 5%, 105% ± 5%, 110% ± 5%, or any other range within 70% to 115%. Saw blade 200 is shown with eight apertures 220 and cutting teeth 230 arranged in two columns of four apertures/teeth. The rows may be staggered as shown so that the cutting teeth 230 in adjacent rows are offset for maximum cutting coverage.	85	Added by DJM 9 2021	9/2/21, 12:00 AM
View Edit Delete	CES-16	Referring now to FIGS. 7, 9, 21, and 23, the oscillating surgical saw blade 200 may include apertures 220 and/or cutting teeth 230 organized into rows and columns. The oscillating surgical saw blade 200 has fewer columns and rows than the surgical saw blade 100 embodiment illustrated in FIGS. 7 and 9. Furthermore, the apertures 220 of the oscillating surgical saw blade 200 can be described as rectangular apertures because of their generally rectangular shape. In one embodiment, each rectangular aperture 220 may be 70% to 115% of a height of an associated cutting tooth 230.	84	Added by DJM 9 2021	9/2/21, 12:00 AM
View Edit Delete	CES-16	FIGS. 19-24 illustrate a top view, front view, right view, back view, and bottom view respectively of the oscillating surgical saw blade 200 of FIG. 15, according to one embodiment. In the illustrated embodiment, of FIGS. 19-24, the front side 202 and opposite back side 204 are the broadest sides of the oscillating surgical saw blade 200. While not necessarily drawn to scale, FIGS. 19-24 illustrate that the front side 202 and back side 204 are broader than the top side 206, bottom side 208, right side 210, and/or left side 212.	83	Added by DJM 9 2021	9/2/21, 12:00 AM
View Edit Delete	CES-16	Each aperture 120 may include an associated cutting tooth 130. In one embodiment, each aperture 120 may be shaped to form a cutting tooth 130. In one embodiment, each aperture 120 may be sized relative to its cutting tooth 130 to be large enough to allow cutting debris to evacuate from the back side 104 through the aperture 120 toward the front side 102.	48	Added by DJM 9 2021	9/2/21, 12:00 AM
View Edit Delete	CES-16	Referring to FIGS. 15-16, the saw blade 200 may include one or more features for connection to a powered handpiece (saw), handle, etc. Oscillating surgical saw blade 200 is shown with a group of saw connection features 260, including a notch 262 that extends into the saw blade 200 through the bottom side 208 and a semi-circular array of rectangular apertures 264 arranged around the deepest portion of the notch 262. The illustrated group of saw connection features 262, 264 is one example of a blade/saw interconnection. Notch 262 may be identical to notch 162, apertures 264 may be identical to apertures 164, and the blade/saw interconnections shown for saw blades 100, 200 may be identical so that saw blades 100, 200 may be used interchangeably with a powered saw handpiece, etc.	81	Added by DJM 9 2021	9/2/21, 12:00 AM
View Edit Delete	CES-16	Because the cutting teeth 230 extend from the back side 204 and from no other side of the oscillating surgical saw blade 200. The front side 202, back side 204, top side 206, and bottom side 208 are non-cutting sides. An oscillating surgical saw blade 200 with a single direction cutting side (e.g., back side 204) and the remaining sides non-cutting sides can help a surgeon by enabling the oscillating surgical saw blade 200 to be positionable in confined spaces around tissue that the surgeon does not want to cut and to contact targeted tissue with the single direction cutting side for very precise and targeted resection of tissue. Having an oscillating surgical saw blade 200 with a one of its six sides being a single direction cutting side and the five remaining sides being non-cutting sides enables the surgeon to position and maneuver the oscillating surgical saw blade 200 for very exact resection procedures on tissue.	80	Added by DJM 9 2021	9/2/21, 12:00 AM
View Edit Delete	CES-16	An oscillating surgical saw blade 200 with a single direction cutting side can provide a surgeon more precise control of when, and where, and in which direction, the oscillating surgical saw blade 200 will cut or resect tissue (e.g., hard or soft tissue). Having a back side 204 as a single direction cutting side can be advantageous because the back side 204 has a greater surface area than the top side 206, bottom side 208, right side 210, and/or left side 212. The greater surface area can facilitate larger planar cuts of tissue.	79	Added by DJM 9 2021	9/2/21, 12:00 AM
View Edit Delete	CES-16	In the illustrated embodiment, the cutting teeth 230 extend from the back side 204 and from no other side of the oscillating surgical saw blade 200. Consequently, the back side 204 is a single direction cutting side. A single direction cutting side is a side of a structure that is configured to cut tissue, but generally cuts the tissue when the structure moves in a single direction and does not cut, or at least does not cut as effectively, in other directions.	78	Added by DJM 9 2021	9/2/21, 12:00 AM
View Edit Delete	CES-16	In one embodiment, a plurality of cutting teeth 230 may be connected to the back side 204. In one embodiment, each cutting tooth 230 includes a cutting edge 232 oriented, or directed, toward a common side. In one embodiment, the common side is the right side 210. In another embodiment, the common side is the left side 212. Having the cutting edge 232 of each cutting tooth 230 directed towards a single side, the common side means that the cutting teeth 230 will cut in a single direction. If the cutting edge 232 of each cutting tooth 230 is directed towards the right side 210, the cutting teeth 230 will cut when the cutting teeth 230 are moved in the direction of the right side 210. If the cutting edge 232 of each cutting tooth 230 is directed towards the left side 212, the cutting teeth 230 will cut when the cutting teeth 230 are moved in the direction of the left side 212.	77	Added by DJM 9 2021	9/2/21, 12:00 AM
