Generally, the cable saw can accommodate a variety of cutting tools that incorporate a flexible cutting line, cutting cord, or cutting wire that is coupled to the adapter device at the opposite end. Thus, the adapter device can apply alternating tension to opposing wire ends of the cutting wire to induce rapid alternating translational motion along the length of the cutting wire.

The lateral extensions of the lateral arms on either side of the hub adapter can allow for a separated connection interface over the span between the opposite ends of the cable saw's cutting wire. In this manner, the adapter device is adapted to translate the angular vibration of the drive shaft of the oscillating power tool to generate a translational see-saw motion at the lateral ends of the adapter's arms. In operation, the translational motion of the arms alternately applies tension to the opposite ends of the cable saw's cutting wire, which pulls and pulls the cutting wire to cut bone, tissue, or various materials, creating friction over the cutting length.

[0012] The present disclosure generally provides an adapter device for a cable saw that can be implemented to modify an oscillating cutting tool to provide cable saw or wire cutting functionality. The power tool can correspond to a surgical power tool that includes a mounting hub configured to couple to a variety of cutting utilities. The power tool can utilize a variety of interchangeable drive heads to complete a variety of tasks. For example, the drive heads can enable a variety of tasks that can include drilling, reaming, sawing, wire / pin driving, deburring, etc. In some cases, the power tool can enable the generation of a rapid oscillating motion that can be applied in conjunction with a saw or cutting blade (e.g., a sagittal saw blade). The adapter device can enable the utilization of a cable saw or wire cutting device that can be utilized with a sawing or oscillating drive head of the power tool interchangeably with other oscillating attachments or cutting tools.

[0013] 1, an exemplary implementation of a power tool 10 with an oscillating drive head 12 is shown. The power tool 10 may include a motor 14 that is enclosed within a housing 16 that forms a grip or handle and is further coupled to a power source 18. Operation of the power tool 10 may be actuated in response to depression of a trigger assembly 20 that may provide power from the power source 18 to the motor 14 such that the oscillating drive head 12 is actuated. Actuation of the oscillating drive head 12 may cause a drive shaft 22 disposed on a mounting hub 24 to rapidly oscillate in alternating clockwise and counterclockwise motions through an angular range α. In various implementations, the angular range may be limited (e.g., approximately 1° to 8°, 3° to 5°, etc.), with the alternating clockwise and counterclockwise motion resulting in a translational oscillatory motion at a distal range 26 of a work attachment 28 of the power tool 10.

[0014] As shown in FIGS. 1-5 , an exemplary embodiment of the work attachment 28 can correspond to an adapter device 30 for a cable saw 32. In various implementations, the adapter device 30 can enable coupling of the cable saw 32 to the mounting hub 24 of the power tool 10 via a hub adapter 34. The hub adapter 34 can accommodate a semicircular or circular mounting interface that can include a mounting pattern 36 with a plurality of mounting openings 38. The hub adapter 34 can be secured to the mounting hub 24 via a clamping mechanism 40 of the power tool 10. When coupled to the mounting hub 24, the rotation axis 42 of the drive shaft 22 can coincide with a central axis 44 of the hub adapter 34. In this manner, angular rotation of the drive shaft 22 of the power tool 10 can rapidly oscillate the adapter device 30 through an angular range α.

[0015] The adapter device 30 may be coupled to opposing wire ends 46 of the cable saw 32 via a coupling interface 48. The coupling interface 48 may include first and second coupling features 48a, 48b that couple to the first and second wire ends 46a, 46b, respectively. Although described with reference to specific exemplary coupling features 48a, 48b, the wire ends 46a, 46b may be permanently fixed (e.g., welded, soldered, crimped, etc.), coupled, or generally held in relation to opposing lateral arms 50 via the coupling interface 48. Each of the coupling features 48a, 48b may be disposed on or coupled to a lateral arm 50 that couples to opposing sides (e.g., first side 52a, second side 52b) of the hub adapter 34. More specifically, in some implementations, the hub adapter 34 can define a proximal end portion 54a that extends along an intermediate axis 56 of the hub adapter 34 to a distal end portion 54b. The distal end portion 54b can correspond to an extension portion 58 that, in an assembled configuration with the vibration drive head 12, extends outwardly along the intermediate axis 56 away from the mounting hub 24. In various implementations, the lateral arms 50 can include a first lateral arm 50a and a second lateral arm 50b that extend vertically or laterally outwardly from the extension portion 58 of the hub adapter 34 to a first lateral end 60a and a second lateral end 60b, respectively. The first coupling feature 48a can be coupled to or disposed at the first lateral end 60a, and the second coupling feature 48b can similarly be coupled to or disposed at the second lateral end 60b. In this configuration, the span S can extend between the mating features 48 a , 48 b that form the mating interface 48 of the hub adapter 34 .

[0016] In operation, the lateral extension of each of the lateral arms 50 over the span S can enable an angular range α of vibration generated by the oscillating drive head 12 of the power tool 10 to be converted into a translational see-saw motion induced in each of the lateral ends 60 and coupling features 48 a, 48 b on the opposing sides 52 of the hub adapter 34. In conjunction with the opposing wire ends 46 of the cable saw 32, the translational vibrating see-saw motion can induce alternating tensions, indicated by numeral 62, that are applied to the opposing wire ends 46 via the coupling features 48 a, 48 b. Thus, rapid alternating angular oscillations of the drive head 12 over the angular range α can result in an alternating see-saw motion induced in the lateral ends 60 of the lateral arms 50 to generate alternating tensions 62. The alternating tension 62, when applied to the opposing wire ends 46, can result in rapid reciprocating motion of the cutting wire 64 of the cable saw 32, which can be utilized to cut material trapped within the cutting loop 66 formed by the cable saw 32. In this manner, the adapter device 30 can enable application of the cable saw 32 as a work attachment 28 for connection to the oscillating drive head 12 of the power tool 10.

[0017] 1-3, in various implementations, the lateral arm 50 can be associated with an extension portion 58 to form an opposing lateral wing mirrored across the intermediate axis 56 of the adapter device 30. As shown in FIG. 3, the extension portion 58 can extend outwardly from the central axis 44 of the hub adapter 34 a reach or extension distance d. In this configuration, the lateral arm 50 can extend perpendicularly outwardly from the extension portion 58 proximate a distal end portion 54b, which can terminate at the extension distance d. Thus, in an assembled configuration in which the hub adapter 34 is engaged by the mounting hub 24, the lateral arm 50 can extend outwardly from the intermediate axis 56 to an opposing side 52 beyond or outside of the opening 68 of the mounting hub 24. In addition to or simultaneously with the lateral extension of the lateral arms 50, the first and second arms 50a, 50b can be disposed about the circumference 70 of the hub adapter 34 and can extend rearward from the distal end portion 54b toward the proximal end portion 54a. For example, the lateral arms 50 can extend perpendicularly outward from the intermediate axis 56 and curve back from the distal end portion 54b toward the proximal end portion 54a. In this configuration, the lateral ends 60a, 60b can be laterally offset from or coincident with a lateral hub axis 72 that extends generally perpendicular to the intermediate axis 56 and through the central axis 44. In this manner, the mating features 48a, 48b can form a mating interface 48 on the opposing side surface 52 and coincide with the lateral hub axis 72.

[0018] 1, 2A, and 2B, the lateral arms 50 extending from the extension portion 58 of the adapter device 30 may include lateral supports 80, support ribs, or lateral stiffening features. The lateral supports may increase the stiffness of the lateral arms 50, particularly in response to rapid angular oscillations over an angular range α and corresponding alternating tensions 62 applied to the lateral ends 60a, 60b. The lateral supports 80 may extend from the distal end portion 54b along an oscillation path 82 that may be defined by a smooth radius of curvature 84 extending from the distal end portion 54b to the lateral ends 60a, 60b. For example, the oscillation path 82 may extend from an intersection between the distal end portion 54b and the intermediate shaft 56 along a convex path extending under the lateral hub axis 72 to each of the coupling features 48a, 48b. In this configuration, the lateral support 80 may be coupled to or form the extension 58 of the hub adapter 34. The hub adapter 34 may define a first thickness T1 and the lateral support 80 may define a second thickness T2 that is greater or thicker than the first thickness T1. In this configuration, the lateral support 80 or support rib may allow for increased stability of the lateral arm 50 when a cantilever load is applied to the lateral ends 60a, 60b to counter the alternating tension 62 applied by the wire ends 46 on opposite sides of the cable saw 32.

[0019] 2B, the first thickness T1 can extend from the hub adapter 34 toward the extension portion 58 and outwardly to the intermediate lateral extent 86 of the lateral arm 50. Additionally, the second thickness T2 of the lateral support 80 can extend along the distal periphery 88 of the adapter device 30 along the vibration path 82. The second thickness T2 of the lateral support 80 can continue from the distal periphery 88 to the lateral end 60 forming the opposite side 52 of the lateral arm 50 and at least partially surround the periphery 60c of the lateral end 60a, 60b joining the features 48a, 48b. In this configuration, the improved strength and stiffness provided by the lateral support 80 can extend outwardly from the intermediate axis 56 of the extension portion 58 over a span S to the lateral end 60 to enable support for various forces that may arise as a result of the rapid vibration and alternating tension 62 applied to the adapter device 30 by the cutting wire 64 of the cable saw 32. Additionally, the first thickness T1 can extend along a proximal portion of the bottom surface 92 of the lateral arm 50 to form a recess 94 extending from the intermediate axis 56 along the proximal end portion 90 of the arm 50 to the intermediate lateral extent 86.

[0020] 1-3, the adapter device 30 may further include one or more support guides 100, which may correspond to a rigid or semi-rigid tubular or pipe-like support structure. The support guide 100 may extend from the bond interface 48 and receive the opposing wire end 46 of the cutting wire 64 within an internal guide passage 102 formed by the support guide 100. As shown in FIGS. 2A and 3, the support guide 100 may extend along the opposing wire end 46 from the bond features 48a, 48b and may be aligned with a cutting plane 104 of the cable saw 32. In this configuration, the cutting plane 104 may be oriented perpendicular to the rotation axis 42 of the drive head 12 and aligned heightwise with the hub adapter 34. Forces applied to the hub adapter 34 through the mounting hub 24 of the oscillating drive head 12 may be transferred along the support guide 100 through an internal guide passage aligned with the cutting plane 104. The resulting alternating tension 62 applied to the opposing wire ends 46 can be maintained in alignment with the cutting plane 104. Thus, the support guide 100 or tubular support can enable improved operation of the cable saw 32 by maintaining directional alignment of the cutting plane 104 and the cutting wire 64 for improved cutting results and consistency.

[0021] 3, 4A, and 4B, as described above, the coupling interface 48 can include a first coupling feature 48a disposed at or coupled to the first lateral end 60a, and a second coupling feature 48b disposed at or coupled to the second lateral end 60b. In some embodiments, one or more of the coupling features 48a, 48b forming the coupling interface 48 can include a receiving opening 106 formed in the lateral end 60 of the lateral arm 50. As described, each of the coupling features 48 can include a receiving opening 106 that can be defined by a circular or cylindrical inner wall 108 extending through the lateral end 60. A receiving groove 110 can be formed in the inner wall 108 of the receiving opening 106, which can be configured to receive a retention spring 112. The retention spring 112 may correspond to a circular or annular shaped retention spring that fits into the receiving groove 110 such that a portion of the retention spring 112 is disposed in a recess within the cylindrical inner wall 108 .

[0022] To mate the opposing wire ends 46 of the cable saw 32 with the receiving openings 106, the mounting pins 114 can be secured to each of the opposing wire ends 46 via crimps, fasteners, or other suitable means. In various embodiments, the mounting pins 114 can form cylindrical mating protrusions 116 configured to engage the receiving openings 106 in a clearance fit configuration. Each of the cylindrical mating protrusions 116 can further include a complementary engagement groove 118 that mates with the receiving groove 110 when the cylindrical mating protrusions 116 are mated with the receiving openings 106. In this configuration, insertion and mating of the cylindrical mating protrusions 116 within the receiving openings 106 can mate the receiving grooves 110 with the complementary engagement grooves 118, and the retention spring 112 is adapted to engage each of the grooves 110, 118 to retain the mounting pin 114 within the receiving openings 106. In this manner, the mounting pins 114 can removably retain opposing wire ends 46 relative to the receiving openings 106 that form the bond interface 48 .

[0023] As shown in detail A of FIG. 3, the engagement of the mounting pin 114 with the receiving opening 106 can allow the mounting pin 114 to rotate within the receiving opening 106. The rotation of the mounting pin 114 within the receiving opening can allow the support guide 100 to swing or pivot about the mating interface 48 formed between the mounting pin 114 and the receiving opening 106. To accommodate the swinging or pivoting, a clearance opening 120 or clearance groove can be formed in the lateral end 60 of the cable saw 32, on the opposite side of the cutting wire 64, where the support guide 100 engages the mating interface 48. Thus, the sweeping path of the cable saw 32 and support guide 100 resulting from the alternating see-saw motion of the adapter device 30 spreads across the clearance opening 120. In this manner, the swinging rotation of the cable saw 32 and support guide 100 is free to vibrate within the clearance opening 120 without interference from the lateral end 60 of the adapter device 30.

[0024] 5, an exemplary embodiment of the adapter apparatus 30 is shown that demonstrates lateral arms 50 extending outwardly from the distal end portion 54b of the hub adapter 34 along the lateral hub axis 72. For example, the lateral arms 50 can extend outwardly from an intermediate portion 130 of the hub adapter 34 near the distal end portion 54b, rather than extending outwardly along the extension portion 58 as described in FIGS. 1-4. In such an embodiment, the distal extent 26 of the adapter apparatus 30 can form a rounded protrusion 132 extending from the hub adapter 34. In this configuration, the hub adapter 34 can be inserted into an opening 68 in the mounting hub 24 of the vibration drive head 12 in an assembled configuration, and the lateral arms can extend outwardly from the opening 68 along the distal end portion 54b. Accordingly, the adapter device 30 may incorporate a lateral arm 50 extending outwardly from the hub adapter 34 along the lateral hub axis 72 to align the first and second coupling features 48a, 48b with the central axis 44 along the lateral hub axis 72.

[0025] 5, the top orthographic view of the adapter apparatus 30 can be implemented with a variable thickness (e.g., a first thickness T1 and a second thickness T2) similar to the implementations shown in FIGS. 1-4, or alternatively can include a uniform thickness extending outwardly from the hub adapter 34 along the lateral arm 50. In various implementations, the bonding interface 48 can enable the bonding features 48a, 48b to be positioned laterally outwardly along a span S between the lateral ends 60a, 60b of the lateral arm 50. In this configuration, the wire ends 46 on opposite sides of the cable saw 32 can be bonded to the hub adapter 34 and mirrored across the intermediate axis 56 and separated across the span S.

[0026] In some embodiments, each of the lateral arms 50 can incorporate a notch 134 extending outwardly from the hub adapter 34 and extending outwardly from the proximal end portion 54a toward the lateral hub axis 72 to the opposing lateral ends 60a, 60b along the lateral arm 50. The notch 134 can allow the hub adapter 34 to be received within the opening 68 of the mounting hub 24 to avoid interference between the lateral arms 50 and the mounting hub 24. Finally, the mating features 48a, 48b that form the mating interface 48 with the cable saw 32 can correspond to the receiving opening 106 having a mounting opening 138 that extends outwardly from the receiving opening 106 to the distal periphery 88 of each of the lateral arms 50. In this configuration, the mounting opening 138 can allow the receiving opening 106 to flex to receive the mounting pin 114 of the cable saw 32. Although specific features and characteristics of the adapter device 30 are described individually with reference to the embodiments of Figures 1-4 and 5, each of the features can be incorporated in various combinations without departing from the spirit of the disclosure.
