View Edit Delete	CES-16	As used herein, “tooth” or "teeth" refers to a structure(s) including a natural body part of a person or animal and/or a structure that functions and/or is structured like a similar structure of a person or animal. A tooth can include a base, one or more sides, and an edge. The edge may come to a point or may taper to a sharp edge. The edge or point may serve to tear or cut through or otherwise engage other objects such as food or other materials. A tooth can also refer to a projection resembling or suggesting the tooth of an animal or person in shape, arrangement, or action. (search "tooth" on Merriam-Webster.com. Merriam-Webster, 2021. Web. 04 Aug. 2021. Modified.) A tooth may be made of natural materials such as bone-like material and/or enamel or may be made of a variety of materials including, but not limited to, metal, plastic, ceramic, wood, fiberglass, acrylic, carbon, biocompatible materials, biodegradable materials or the like.	112	Added by DJM 9 2021	9/2/21, 12:00 AM
View Edit Delete	CES-16	Because the cutting teeth 130 extend from the back side 104 and from no other side of the surgical saw blade 100. The front side 102, back side 104, top side 106, and bottom side 108 are non-cutting sides. A non-cutting side is a side of a structure that is configured to generally not cut tissue when placed in contact with the tissue, regardless of movement of the structure in any direction.	52	Added by DJM 9 2021	9/2/21, 12:00 AM

View Edit Delete	CES-16	FIG. 8 illustrates a right side 110 view. FIG. 9 illustrates a back side 104 view. FIG. 10 illustrates a bottom side 108 view. In FIGs. 7 and 9, surgical saw blade 100 is shown with twenty-seven apertures 120 and cutting teeth 130 arranged in three columns of nine apertures/teeth. The rows may be staggered as shown so that the cutting teeth 130 in adjacent rows are offset for maximum cutting coverage. In one embodiment, certain parts of rows or columns may include no apertures 120, no cutting teeth 130, or neither apertures 120 nor cutting teeth 130.	62	Added by DJM 9 2021	9/2/21, 12:00 AM
View Edit Delete	CES-16	Referring to FIG. 7, the cutting tooth 130 inside the detail circle 11 is offset toward the top (free end, top side 106) of the surgical saw blade 100 relative to the top cutting tooth 130b in the center column. In one embodiment, the offset may be equal to the width of the tooth 130. Each cutting tooth 130 may be angled or bent so that the free end (i.e., cutting edge 132) of the cutting tooth 130 protrudes outwardly from the remainder of the surgical saw blade 100. The cutting teeth 130 are shown protruding outwardly from the back side 104. Each cutting tooth 130 may include one or more side bevels 134 (See FIG. 11) along the edge(s) of the tooth, which may sharpen the tooth for cutting along the back side 104.	61	Added by DJM 9 2021	9/2/21, 12:00 AM
View Edit Delete	CES-16	The surgical saw blade 100 may be designed for use with an oscillating saw that sweeps the surgical saw blade 100 side to side along an arcuate path 170 (See FIG. 7). When the surgical saw blade 100 is actuated in this way, the cutting teeth 130 cut bone, cartilage, or other hard or soft tissues next to, or against the back side 104 (i.e., a single direction cutting side) when the surgical saw blade 100 sweeps toward the left side 112. The cutting teeth 130 do not cut when the surgical saw blade 100 sweeps toward the right side 110, nor does the surgical saw blade 100 cut tissues that are next to, or against the front, right, and/or left side 102, 110, 112 (i.e., non-cutting sides).	60	Added by DJM 9 2021	9/2/21, 12:00 AM
View Edit Delete	CES-16	FIG. 7 illustrates an embodiment in which the that apertures 120 of one row R overlap apertures 120 of an adjacent row R and the cutting teeth 130 of one row R overlap apertures 120 of an adjacent row R. However, the cutting teeth 130 of one row R do not overlap cutting teeth 130 of an adjacent row R. This non-overlapping pattern of cutting teeth 130 may limit bone removal while the surgical saw blade 100 is actuated while being held in one location. Re-positioning the surgical saw blade 100 to a different location may permit additional bone removal. Alternatively, or in addition, in another embodiment, cutting teeth 130 of one row R may overlap cutting teeth 130 of an adjacent row R.	59	Added by DJM 9 2021	9/2/21, 12:00 AM
View Edit Delete	CES-16	FIG. 7 illustrates one example of a variety of configurations of the apertures 120 and cutting teeth 130. In the illustrated embodiment, each row R of cutting teeth aligns with apertures 120 of at least one adjacent row R of cutting teeth 130. For example, row R1 includes a single aperture 120a and single cutting tooth 130a. The cutting tooth 130a aligns horizontally with the two apertures 120 in the adjacent row R2. Said another way, the apertures 120 and cutting teeth 130 of one row overlaps the apertures 120 and cutting teeth 130 of an adjacent row. In this manner, the cutting teeth 130 in row R1 and row R2 cooperate to engage the surface that the back side 104 contacts to make efficient cuts of the tissue. FIG. 7 includes the same overlap and/or alignment for cutting teeth 130 in the other rows R1-n. FIG. 7 also illustrates that the apertures 120 of one row R overlap apertures 120 of an adjacent row R.	58	Added by DJM 9 2021	9/2/21, 12:00 AM
View Edit Delete	CES-16	FIGS. 6-7 illustrate an embodiment in which the surgical saw blade 100 includes a plurality of cutting teeth 130 arranged, or organized, into a plurality of rows (R1 – Rn) and columns (C1-Cn). In the illustrated embodiment, each row R of cutting teeth 130 is configured such that the plurality of cutting teeth 130 in each row R are aligned horizontally and each column C of cutting teeth 130 is configured such that the plurality of cutting teeth 130 in each column C are aligned vertically. Of course in other embodiments, cutting teeth 130 in one or more rows R may follow an arcuate path of alignment and/or cutting teeth 130 in one or more columns C may follow an arcuate path of alignment.	57	Added by DJM 9 2021	9/2/21, 12:00 AM

FIGS. 3-4 illustrate details of an aperture 120, cutting tooth 130, cutting edge 132, and a bevel 134.	55	Added by DJM 9 2021	9/2/21, 12:00 AM
View Edit Delete	CES-16	The surgical saw blade 100 may include one or more features for connection to a powered handpiece (saw), handle, etc. In one embodiment, the surgical saw blade 100 may also include a saw connection feature 160 near the bottom side 108. Surgical saw blade 100 is shown with a group of saw connection features 160, including a notch 162 that extends into the surgical saw blade 100 through the bottom side 108 and a semi-circular array of rectangular apertures 164 arranged around the deepest portion of the notch 162. The illustrated group of saw connection features 160 is one example of a blade/saw interconnection.	54	Added by DJM 9 2021	9/2/21, 12:00 AM
View Edit Delete	CES-16	A surgical saw blade 100 with a single direction cutting side and the remaining sides non-cutting sides can help a surgeon by enabling the surgical saw blade 100 to be positioned 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 a surgical saw blade 100 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 surgical saw blade 100 for very exact resection procedures on tissue.	53	Added by DJM 9 2021	9/2/21, 12:00 AM
View Edit Delete	CES-16	Referring to FIGS. 11-12, the aperture width 122 may be a percentage of the cutting tooth height 124. The percentage of the aperture width 122 in relation to the cutting tooth height 124 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%. The aperture height 126 may be greater than a cutting tooth width 128. In one embodiment, the aperture 120 has a rectangular shape. In the illustrated embodiment, the aperture 120 has two parallel sides that are connected by an arcuate side. The aperture 120 includes an open side that is in communication with the cutting edge 132. Alternatively, or in addition, the aperture 120 may include be straight instead of arcuate as depicted in FIG. 11. In certain embodiments, the aperture 120 is considered adjacent to the cutting tooth 130.	64	Added by DJM 9 2021	9/2/21, 12:00 AM
View Edit Delete	CES-16	A surgical saw blade 100 with a single direction cutting side can help a surgeon to have more precise control of when and where and in which direction the surgical saw blade 100 will cut or resect tissue (e.g., hard or soft tissue). Having a back side 104 as a single direction cutting side can be advantageous because the back side 104 has a greater surface area than the top side 106, bottom side 108, right side 110, and/or left side 112. The greater surface area can facilitate larger planar cuts of tissue.	51	Added by DJM 9 2021	9/2/21, 12:00 AM
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
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	The surgical saw blade 100 may include one or more apertures 120 which may extend through the surgical saw blade 100 between the front and back sides 102, 104. In one embodiment, each aperture 120 may have the same or a similar size and shape. Alternatively, or in addition, one or more apertures 120 may have the same or a similar size and shape and one or more other apertures 120 may have a different size and shape.	47	Added by DJM 9 2021	9/2/21, 12:00 AM
View Edit Delete	CES-16	Referring to FIGS. 1-2, a surgical saw blade 100 has a front side 102, an opposite back side 104, a top side 106, an opposite bottom side 108, a right side 110, and an opposite left side 112. The surgical saw blade 100 may have a variety of shapes and sizes. In one embodiment, the surgical saw blade 100 is rectangular having a right side 110 and left side 112 longer than a top side 106 and bottom side 108. In one embodiment, the right side 110 and left side 112 may be of similar length and the top side 106 and bottom side 108 may be of similar length.	46	Added by DJM 9 2021	9/2/21, 12:00 AM
