Description

Priority requirements

[0001] This application claims the benefit of U.S. Provisional Patent Application No. 63 / 555,352, filed February 19, 2024, entitled “Dental Instrument Holder And Expansion Platform”, which is incorporated herein by reference. Technical Field

[0002] The embodiments described herein relate to methods and apparatus for extending existing systems to accommodate tools and to provide the capability to route tool cables within the system. Example embodiments include dental delivery systems. Background Technology

[0003] Dental delivery systems are used to hold a variety of tools for dentists. These tools traditionally include instruments that provide pressurized air, suction, and water, as well as electrically powered or turbine-operated mechanical instruments such as cutting burs and polishing discs. These handheld tools are typically held in a series of standardized slots within the system, making them easily accessible to the dentist. Hose or cable extensions for the tools reach into associated equipment that may be near the system. However, dental delivery systems typically lack the capacity to accommodate new, non-standard types of tools, and system replacement is impractical due to the high cost and widespread use of dental delivery systems.

[0036] In the following detailed description, reference is made to the accompanying drawings, which form part of the detailed description, and in the drawings, practical embodiments are illustrated by way of illustration. It should be understood that other embodiments may be utilized, and structural or logical changes may be made without departing from the scope. Therefore, the following detailed description should not be construed in a limiting sense, and the scope of the embodiments is defined by the appended claims and their equivalents.

[0037] Various operations can be described sequentially as a plurality of discrete operations in a manner that may help to understand the implementation; however, the order of description should not be interpreted as implying that these operations are sequentially related.

[0038] Descriptions may use perspective-based terms such as up / down, back / front, and top / bottom. Such descriptions are used only to facilitate the discussion and are not intended to limit the application of the disclosed embodiments.

[0039] The terms “connection” and “link”, as well as their derivatives, may be used. It should be understood that these terms are not intended to be synonyms. Rather, in certain implementations, “connection” can be used to indicate that two or more elements are in direct physical contact with each other. “Link” can mean that two or more elements are in direct physical contact. However, “link” can also mean that two or more elements are not in direct contact with each other, but still cooperate or interact with each other.

[0040] For descriptive purposes, phrases in the form of "A / B" or "A and / or B" mean (A), (B), or (A and B). For descriptive purposes, phrases in the form of "at least one of A, B, and C" mean (A), (B), (C), (A and B), (A and C), (B and C), or (A, B, and C). For descriptive purposes, phrases in the form of "(A)B" mean (B) or (AB), where A is an optional element.

[0041] The description may use the terms "implementation" or "various implementations," which may each refer to one or more implementations of the same or different implementations. Furthermore, the terms "comprising," "including," "having," etc., used with respect to various implementations are synonymous and are generally intended as "open-ended" terms (e.g., the term "comprising" should be interpreted as "including but not limited to," the term "having" should be interpreted as "at least having," and the term "including" should be interpreted as "including but not limited to," etc.).

[0042] Regarding the use of virtually any plural and / or singular terms in this document, those skilled in the art may appropriately convert plural to singular and / or singular to plural depending on the context and / or application. For clarity, various singular / plural permutations may be explicitly described herein.

[0043] As mentioned at the beginning, there are various challenges in adding new tools to existing systems.

[0044] One possible example relates to a dental delivery system. A typical dental delivery system may include a console, also known as a control head, having: slots sized to hold handheld dental tools; and / or arms configured to have slots for holding these tools. Exemplary systems include those available from A-dec Inc., Newberg, and Oregon.

[0045] However, these slots are not suitable for holding certain new types of tools, such as certain scanners, curing lamps, touchpads, apex locators, or other instruments, whether cabled or uncabled. The term "cable" as used herein can include, for example: cables comprising wires encased in a sheath; conduits, such as one or more tubes carrying water or air; or sheathed systems of conduits and / or one or more cables. For example, 3D dental scanners are becoming increasingly common. One example is the Primescan® intraoral scanner, available from Dentsply Sirona, Charlotte, NC. 3D scanning of a patient's teeth can be used, for example, for the rapid design and construction of dental implants, for assessing teeth to provide necessary care, and for forming orthodontic braces. To create a 3D scan of the oral cavity, the dentist scans the upper and lower bridges of the patient's teeth using a handheld digital scanner. The dentist holds the scanner in one hand while moving the scanner lens / tip over the upper and lower dental arches. A beam of light exits from the scanner lens and reflects off the teeth. The scanner measures the beam and creates a 3D image of the beam measurement. The scanner can be connected to a laptop computer or other computer via a cable.

[0046] However, these scanners are currently difficult to integrate into the workflow of commonly used dental handheld devices. In particular, the scanners are mounted on mobile carts independent of tool holding systems. For example, the mobile carts must be moved and plugged into wall sockets for use in different operating rooms within a dental clinic. Furthermore, the location and use of the scanner carts put dentists in awkward and uncomfortable postures.

[0047] Attaching scanners to existing systems presents numerous challenges. For example, the attachment device must be compatible with systems of different sizes and shapes. Other objectives may include ease of cleaning, ease of attachment, right / left-hand accommodating design, minimizing or avoiding interference with existing tools, affordability, ease of system and manufacturing, mechanical durability, accommodating different tool holders or other retaining mechanisms, and aesthetics. Other objectives may include avoiding collisions with existing swing arms, trays, undermounts, chairs, chair arms, stools, cabinets, monitors, touchpads, handheld device tubing overhangs, and tabletops.

[0048] The solutions provided in this paper address the aforementioned and other issues. In one aspect, an attachment device is provided that allows the integration of non-standard-sized, for example, larger-than-standard-sized tools into an existing system with standard-sized tools. The attachment device may include a bracket that holds a scanner or other tool proximate to a standard-sized tool, making the scanner or other tool easily accessible to dentists or other users. In another aspect, the attachment device may hold the tool's cable and route the tool's cable to electronic components within a control panel or other location.

[0049] In an example implementation, an attachment device is attached to an arm that includes slots for holding standard-sized tools. The attachment device may include a clamp that attaches the adapter body and retainer over one of the slots, leaving the remaining slots available for standard-sized tools. The adapter body may be configured to avoid interfering with bumps or other protrusions extending from the arm to hold the standard-sized tool. For example, the adapter body may include: curved edges configured to contact a front portion of the arm; a cavity located between the curved edges that accommodates the bump; and a tensioning screw seated outside the cavity within the adapter body, and the tensioning screw may extend in a generally horizontal orientation. The clamp may include protrusions that attach to the adapter body at a first end of the clamp and to the tensioning screw via fasteners at a second end of the clamp. When the tensioning screw has a left-hand thread, clockwise rotation of the tensioning screw results in tightening.

[0050] In another example implementation, the attachment device includes a retainer for non-standard sized tools and also has the capability to retain and route the cable from the tool to the control console for attachment to electronic components in the control console or other locations. The cable can provide power to the tool and transmit / receive data.

[0051] The attachment device may include a body and a cover, wherein a cable extends along a channel formed by corresponding upper and lower surfaces within the body and the cover. When the cover is attached to the body, the cable is compressed in a compression section of the device between a first channel surface of the body and a second channel surface of the cover to provide stress relief for the cable. The cover also includes a receiving portion having an internal cutout or internal groove for engaging with a flange in a cable sheath. When the cover is attached to the body, a gate-like portion of the cover engages with the receiving portion to hold the cable sheath in place. The gate-like portion includes a corresponding internal groove.

[0052] The above and other features can be further understood in light of the following discussion.

[0053] Figures 1 to 11 This primarily relates to embodiments of attachment devices attached to an arm, the arm including slots for holding standard-sized tools.

[0054] Figure 1An example dental delivery system 100 according to various embodiments is depicted. The delivery system includes a dental workstation on the left and an assistant workstation on the right. The dental workstation or delivery system may include, for example, tools, such as electric or pneumatic handpieces for operating rotating instruments such as cutting burs and polishing discs, ultrasonic scalers, intraoral cameras, air / water syringes, or other tools. The assistant's instruments may include, for example, air / water syringes, suction instruments, such as large-volume extractors and saliva extractors, or other tools. These tools are held on horizontally extending instrument arms 110 and 120 and include cables leading to various locations within the system.

[0055] Arms 110 and 120 can have diameters of 1.5 inches and 2 inches respectively, as used in dental operating rooms. Other diameters are also possible.

[0056] Figure 2A Depicting various implementation methods and Figure 1 An example implementation of a dental delivery system 100 with a separate scanning station 200. The scanning station includes a body 201 with pulleys housing electronic components, a display screen 202, and a scanner 210.

[0057] Figure 2B Depicting various implementation methods Figure 2A An example implementation of scanner 210 is provided. The scanner includes: a tip 213, which is placed in a patient's mouth to obtain images of the oral cavity; a body 211, which may contain electronic components for power and data; and a cable 212, which is connected to the electronic components in the body via a pulley. For example, the electronic components may provide the scanner with a 24V voltage and transmit and receive data.

[0058] Figure 3A Depicting various implementation methods Figure 1 and Figure 3A An enlarged view of an example of a long arm 110. In this example, the arm has a generally cylindrical portion 312, but other shapes are also possible. The arm includes three slots 310, 315, and 320 for standard-sized tools, such as... Figure 1 As depicted in the diagram. Additionally, protrusions or projections of the groove 310, such as protrusions 311 and 313, extend from the front side of the arm to help hold the tool. In other implementations, protrusions are not used. In some cases, the groove is tapered to facilitate tool retention. The groove may also have the ability to rotate within a limited range relative to the longitudinal axis of the arm to allow for optimal positioning.

[0059] The arm has a front part 110f and a rear part 110b.

[0060] Figure 3B Depicting various implementation methods Figure 3A An example profile view of the elongated arm 110 along the protrusion 311 in the yz plane. The arm includes a cylindrical portion 312 and the protrusion 311. As mentioned, the arm can have other cross-sectional shapes. For example, the cross-section can be generally circular, such as elliptical. The arm can include both circular and planar surfaces, or entirely planar surfaces, such as polygonal, square, or other rectangular shapes.

[0061] Figure 4 Descriptions of various embodiments for use with Figure 1 and Figure 3A An external side view of an example implementation of the adapter 405 and retainer 410 used together with the elongated arm 110. The retainer 410 may be in the form of a bracket for holding tools, such as... Figure 2A The scanner 210. Other holding mechanisms are also possible, such as hooks, pins, or hangers. The retainer can be fixed or movable, for example, holding the tool by a spring-loaded arm. In one approach, the retainer can hold the tool in a generally vertical orientation.

[0062] In this example, the retainer is attached to the adapter body 415 of the adapter 405. In another example, the retainer is integral with the adapter body, or formed as a single piece with the adapter body. The retainer and adapter body can be formed of plastic or other suitable materials. The retainer can be easily replaced in the field for equipment upgrades or modifications.

[0063] The adapter 405 also includes a belt clamp 420 extending around the arm 110. In one approach, the belt clamp is initially in a released position to allow the adapter to slide onto the arm from its free end. The belt clamp should open to the extent required to slide over the arm and any protrusions or other projections. The clamp may be attached to a tension screw in the adapter body, the head of which is externally accessible to tighten or loosen the clamp. A user can use a screwdriver to tighten or loosen the clamp. When the clamp is tightened, it grips the surface of the arm, including the rear side 110b, to hold the adapter body and retainer in place. In one approach, the clamp may be formed of a sheet of steel.

[0064] The arm may include plastic, which is easily damaged when the clamp is tightened. Powder coating the clamp can avoid this problem. Another approach is to provide a plastic liner.

[0065] Figure 5 Depicting various implementation methods Figure 4A cross-sectional view of the adapter 405 and retainer 410. The tensioning screw 430 is held within the adapter body 415 to adjust the tightness of the clamp 420. The term "screw," etc., refers to, for example, any threaded fastener, which may be called a screw, bolt, or other fastener.

[0066] The clamp may include: a first end 420-1 (see Figure 6A and Figure 6B ), the first end 420-1 is, for example, via screw 419 ( Figure 10 The first end portion 420t1 of the clamp is fixed to the adapter body; and the second end portion 420-2 is fixed to the fastener 440. The fastener may include, for example, a nut or other fasteners with internal threads. In particular, the first protrusion 420t1 of the first end portion of the clamp may be fixed to the adapter body by a screw, and the second protrusion 420t2 of the second end portion of the clamp may be fixed to the fastener.

[0067] The fastener is threaded onto the threaded shaft 432 of the tensioning screw. The tensioning screw 430 has a tip 433 with a circumferential groove 434, which is held in a first seat 450 of the adapter body to limit upward movement. Downward movement of the tip 433 can be limited by a retaining screw 445 positioned from the bottom side of the adapter body.

[0068] The tensioning screw 430 has a head 431, which can be slotted, Phillips head, square head, hexagonal, etc., to allow the screw to be driven with common hand tools. This head is held in a second seat 439 of the adapter body. The first and second seats of the adapter body substantially prevent longitudinal movement of the tensioning screw. The first and second seats can be bow-shaped to allow rotational movement of the tensioning screw. The tensioning screw 430 is located outside and below a cavity 421 of the adapter body, which receives a protrusion 311 of the arm. This cavity can be correspondingly formed on the first curved edge 461 and the second curved edge 462 of the adapter body (see...). Figure 6C Between the first curved edge 461 and the second curved edge 462, the front side 110f of the contact arm is contacted when the clamp is tightened.

[0069] In one approach, the screw has a left-hand thread, such that clockwise movement of the tensioning screw 430 results in tightening of the clamp by moving the fastener forward (towards the tip 433). This is advantageous because the screw allows the screw head to be located at the rear of the adapter body, away from the retainer. This position places the clearance for dirt buildup away from the patient's work area and the dentist's hands.

[0070] Alternatively, the screw can be flipped from the shown orientation, where the screw head can be accessed through a hole in the retainer / carrier. However, this causes the screw head to enter a gap in the hole, which can trap dirt and transfer it back to the scanner or other tools.

[0071] The tensioning screw can be positioned such that its longitudinal axis extends approximately horizontally, for example, within + / - 30 degrees in the horizontal direction.

[0072] In one approach, the tensioning screw, retaining screw, and screw for attaching the adapter body to the retainer are all positioned away from or hidden relative to the retainer, so that they are not affected by debris accumulating from the patient's work area.

[0073] Figure 6A Depicting various implementation methods Figure 4 An example side view of the clamp 420 in the yz plane. The clamp includes a belt 420b, which terminates at a first end 420-1 having a bend 420a and a first protrusion 420t1, and at an opposite second end 420-2 having a second protrusion 420t2. The belt may have a generally circular shape or a shape otherwise corresponding to the cross-sectional shape of the arm.

[0074] Figure 6B The following describes the path according to various implementation methods. Figure 6A The image shows an example front view of the clamp 420 in the xz plane, viewed in the direction of arrow 610. The first protrusion 420t1 has two holes to allow screws to be used to secure the first protrusion to the adapter body. The second protrusion 420t2 has two protrusion portions 420t2a and 420t2b to allow the second protrusion to be secured to a fastener. The space 611 between the protrusion portions provides space for a tensioning screw. In this example, the fastener may include two threaded holes aligned with corresponding holes in the protrusion portions 420t2a and 420t2b to allow screws to secure the fastener to the protrusion portion.

[0075] Figure 6C Depicting various implementation methods Figure 4 An example structure of the adapter body 415 is shown. The adapter body includes: a front side portion 460 facing the arm, the front side portion 460 being attached to the arm; a opposite rear side portion 463; a top side portion 464; a bottom side portion 466; and opposing sidewalls, including sidewall 465. As mentioned, the front side portion accordingly has a first curved edge 461 and a second curved edge 462, the first curved edge 461 and the second curved edge 462 contacting the arm when the clamp is tightened, and a cavity 421 is formed between the first curved edge and the second curved edge.

[0076] Figure 7An example cross-sectional view of an adapter body 415 according to various embodiments, taken in the yz plane along the tensioning screw 430, is depicted. This view provides further details of the tensioning screw 430, the fastener 440, the tip 433 of the tensioning screw, and a first seat 450 of the adapter body in which the tip rests. The seat 450 allows the tip and the tensioning screw to rotate without moving along the longitudinal direction of the tensioning screw. The head of the tensioning screw can be held in a second seat 439 of the adapter body, as mentioned.

[0077] Figure 8 An example cross-sectional view of the adapter body 415 according to various embodiments is depicted, showing the threads of the tensioning screw 430. This view provides further details of the retaining screw 445, the first seat 450, the tensioning screw 430 (including its tip 433), the fastener 440, and the protrusion 420t2a that is secured to the fastener, for example, by a rivet or screw 467.

[0078] Figure 9 An example cross-sectional view of the adapter body 415 according to various embodiments is depicted, showing the force on the tensioning screw 430. This tensioning mechanism is the opposite of a commonly used pipe clamp, because the tip of the tensioning screw is loaded against the adapter body seat 450. In this case, there is a force F in the leftward direction and a corresponding resistance Fr in the rightward direction.

[0079] Figure 10 An example cross-sectional view of an adapter body 415 according to various embodiments is depicted, showing the attachment of the adapter body 415 to the clamp 420 and the retainer 410. As mentioned, the adapter body may be a separate component from the retainer. In this case, a fastener such as a screw 468 may be used to attach the adapter body to the retainer. Other details include a tensioning screw 430, a fastener 440, protrusions 420t2a and 420t2b, and a retaining screw 445. In this example, the fastener is rectangular and includes two threaded holes to allow for securing the two protrusions 420t2a and 420t2b.

[0080] Figure 11An example cross-section of a comparative adapter body 1115 with a vertical tensioning screw 1130 according to various embodiments is depicted. In this case, the clamping band 1120 includes a first end 1121 attached to a fastener 1140 and a second end 1122 attached to the adapter body 1115. A retainer 1110 is attached to the adapter body 1115. When the tensioning screw is turned clockwise, for example driven from the head at the bottom, the fastener and band move downwards. The problem with this arrangement—which represents a typical pipe clamp—is that the tensioning screw may collide with the protrusion 311 of the arm 110. To avoid collision, the size of the adapter body would have to be increased at least in the y-direction. This increase in size would cause the tool position to move further away from the arm and thus apply a greater torque, which might require further increases in the size of the band or other components, thereby increasing costs and taking up more space in the work area.

[0081] In contrast, as discussed above, a solution can be found by creating a cavity within the adapter body and moving the tensioning screw to a position outside the cavity that does not interfere with the protrusion on the front side of the retaining tool's arm.

[0082] Figures 12 to 18 The invention primarily relates to embodiments of attachment devices, which include a retainer for non-standard sized tools and also have the capability to retain cables and route them from the tool to a control console for attachment to electronic components in the control console or other locations.

[0083] Figure 12 Example views of an attachment device 1200 for a tool console 1250 according to various embodiments are depicted. The tool console includes multiple slots 1251 to 1256 for holding tools. Each tool typically has a cable connected to an air source, water source, power source, suction source, or electronic data control source. In this example, the console is limited to holding six tools of the same standard size.

[0084] To extend the capabilities of the console, attachment devices can be mounted on the left and / or right sides of the console. In this example, attachment device 1200 is mounted on the left side of the console. The console may have opposite top and bottom sides, opposite left and right sides, and opposite front and rear sides. The attachment device can be used to route cable 1220 into the interior of the console via an opening formed in the side of the console. In the example implementation, the opening is plastic or metal and can be easily cut to provide a port, or there may be a pre-cut opening. The cable may have opposite ends (not shown), which may be attached, for example, to electronic components within the console, such as a junction box or instrument control module, or the cable may exit the console through another opening in the console and be routed to another location, such as a computer. In one method, the cable can deliver power and / or data to a tool held in retainer 1211. One possible implementation of the tool involves, for example... Figure 2B The depicted dental scanner. Data may include control signals sent to the tool and image data received from the tool. The retainer may be secured to the attachment device 1200, for example, via arm 1210. In another method, the retainer is directly secured to the attachment device without arm 1210 or other intermediate support.

[0085] These methods ensure that tools are easily accessible and cables are kept close to the tools to minimize the required cable length and help prevent cables from getting tangled with other instrument cables connected to the dental delivery system.

[0086] In another implementation, the cable is used for tools or other devices that are not held in retainer 1211, and / or no retainer is provided.

[0087] The cable may include connector 1221, which is configured to detachably connect to the tool cable. This allows different tools to be easily connected to and disconnected from the cable. Additionally, a given tool can be easily detached from the connector and attachment device at one location and moved to another location, where it can be easily attached to the connector and attachment device at that other location. For example, a dentist can easily move a scanner from one operating room to another.

[0088] A cable sheath 1222 surrounding cable 1220 is received in a receiving portion 1201r of attachment device 1200 to hold the cable in place. The cable is laid through a channel with compression sections that compress or squeeze the cable to hold it in place. The opposite end of the cable can be laid from the end of attachment device 1200 into the interior of the control console.

[0089] Figure 13 Depicting various implementation methods Figure 12 Example view of the interior of the tool console 1250, which has Figure 12 The left-side attachment device 1200 and the right-side attachment device 1280 are included. In an example implementation, the tool console may include a housing for setting electronic components. A possible example is a console that holds dental tools and provides power to them.

[0090] The left side of the figure depicts an attachment device 1200 that routes cable 1220 internally, while the right side depicts an attachment device 1280 that routes cable 1302 internally. Attachments 1200 and 1280 are mounted to an internal frame using brackets 1310 and 1320, respectively. The brackets can be identical to allow the same bracket to be used for operation on either the left or right side, thus providing flexibility for the end user and efficiency for the manufacturer. The attachments may extend partially into openings, such as through-holes 1330, cut or otherwise provided on the left and right sides of the console. Mounting holes 1340 are also provided for attaching brackets 1310 and 1320 to the console. Cables can be attached to a junction box 1255 or other components within the console, or the console can act as a pathway for cables to be routed to another location. The junction box may include ports for attachment to a power supply unit, which in turn is connected to an AC mains power source. The connection box may include another port, such as a Universal Serial Bus (USB) port, for connecting to a computer, such as a laptop computer.

[0091] Therefore, this example extends the console's capabilities to include two non-standard sized additional tools. Theoretically, additional tools could also be accommodated via additional attachment devices.

[0092] Figure 14 Depicting various implementation methods Figure 12 A view of an example implementation of the attachment device 1200 and associated structures. In the example implementation, the attachment device includes a body 1201 and a bottom cover 1202 or a cover. The body may include an opening 1201a (see also...). Figure 15 The arm 1210 of retainer 1211 is inserted and held through opening 1201a. In one method, the opening extends through the body, allowing the arm to be inserted into either side of the body. This allows the attachment device to be used on either the left or right side of the control panel. For example, because the screws that attach the retainer to the arm (on the back side of arm 1210) are easily accessible, retainer 1211 can be easily replaced in the field with different types of retainers.

[0093] The body also includes a receiving portion 1201r to receive a sheath 1222 of the cable 1220. In an example implementation, the receiving portion has a cylindrical interior extending along a major arc of a circle, for example, greater than 180 degrees of the circle. The receiving portion has a gap on one side that is closed by a gate-like portion 1202g of the cover 1202 when the cover is attached to the body. The gate-like portion may extend along a minor arc of a circle, for example, less than 180 degrees of the circle, and engages with the receiving portion when the cover is attached to the body.

[0094] Other methods of securing the cable sheath to the attached device are also possible.

[0095] The cable 1220 passes upward through the receiving section and is routed in the internal channel toward the end 1201e of the body. The bracket 1310 can be attached to the attachment device, for example, using screws. The bracket may be L-shaped and includes a flat plate 1310a for attachment to the bottom surface of the attachment device, a vertical bend 1310b, and an elongated flat plate 1310c for attachment to the control panel.

[0096] The bracket has: a first end portion 1310e1 configured to be fastened to a spaced-out arm; and a second end portion 1310e2 configured to be attached to a dental tool console 1250.

[0097] Figure 15 Depicting various implementation methods Figure 14 An exploded view of the attachment device 1200 and associated structures. Arm 1210 includes a flat bracket 1210b, which is screwed to the underside of body 1201 after passing through opening 1201a. Body 1201 correspondingly includes a first arm 1201a1 and a second arm 1201a2, which can be screwed onto flat plate 1310a. Cover includes a channel surface 1202c, which extends partially over an extension 1202e of the cover. When the cable is in place and the cover is attached to the body, the channel surface 1202c abuts the cable against the corresponding channel 1201c in the body. Figure 16 Compression. The cover can be attached to the body using additional screws 1510.

[0098] The arm 1210 has a first end 1210e1 connected to the tool holder 1211 and a second end 1201e2 near the body that can be attached to the bottom 1201b of the body, wherein a cover 1202 covers the second end of the arm.

[0099] The body 1201 may be elongated and accordingly have a top 1201t and a bottom 1201b, as well as opposite first ends 1201e1 and second ends 1201e2. Furthermore, the body includes a receiving portion 1201r located at the bottom and spaced-apart arms 1201a1 and 1201a2 located at the first ends. The receiving portion 1201r has a grooved cylindrical interior. The receiving portion is configured to retain the cable sheath 1222, and the cylindrical interior extends along a major arc of a circle.

[0100] The cover includes an outlet channel 1202ec located between spaced-out arms to guide a cable to an end 1201e of the body 1201. The cable may be exposed to the outside of the body within the outlet channel. The outlet channel guides the cable to a first end 1201e1 of the body to position the cable in place for entry into the dental tool console.

[0101] Figure 16 Depicting various implementation methods Figure 14 An exploded cross-sectional view of the attachment device 1200 in the yz plane, showing screws 1510 and brackets 1310 being removed from the attachment device 1200. A channel 1200c is formed in the attachment device, located between a first channel surface 1201c of the body and a second channel surface 1202c of the cover. The first and second channel surfaces extend from the receiving portion to the end of the body. The spacing or interval Sp between the channel surfaces can vary along the length of the channel. In one method, this distance is specified in the compression section 1200cs of the channel. Figure 17 The minimum Sp_min is at (). The cable is captured and slightly compressed in a compressed section having a length L of at least 0.2 inches to 0.7 inches or at least 0.5 inches to 0.7 inches.

[0102] This provides a relatively long compression section to offer robust cable retention and stress relief, thus resisting accidental cable pull-out or pull-out due to worst-case loading scenarios. Furthermore, it significantly reduces the likelihood of localized stress within the cable and cable breakage compared to, for example, point loading. This design can handle lateral loading, such as if a user accidentally removes the scanner or other tool while attaching it to the cable, and vertical downward loading, such as if a user steps on the cable.

[0103] The surface of the first channel may be parallel to and / or equidistant from the surface of the second channel along the entire length of the compressed section of the channel.

[0104] Specific channel geometry also mandates adherence to minimum cable bending radius specifications.

[0105] Screw 1650 is also depicted, which is used to attach the bracket to the body and hold the extension of the cover against the body.

[0106] Figure 17 Depicting various implementation methods Figure 16 A cross-sectional view of the attachment device 1200, wherein screws 1510 and brackets 1310 are attached to the attachment device 1200 to provide a compression section 1200cs for a channel 1200c. Screws 1510 and 1650 are positioned to secure the cover to the body and provide compressive force across the cable in the compression section. In one approach, the screws are not placed directly beneath the compression section. Alternatively, placing the screws in front of and behind the compression section creates a bending effect on the cover.

[0107] Therefore, in the example implementation, the cover is fastened to the body at one side of the compression section, at a first position 1700 spaced apart from the compression section of the channel, and at a second position 1701 spaced apart from the compression section on the opposite side of the compression section. However, the cover is not fastened to the body at a position between the first and second positions, nor is it fastened to the body in any other way directly below, above, or to the side of the compression section.

[0108] Alternatively, fasteners can be provided to attach the cover to the body at a location directly below the compression section.

[0109] Figure 18 A cross-sectional view of the attachment device 1200 according to various embodiments is depicted in the xz plane, showing the first channel surface 1201c and the second channel surface 1202c along... Figure 17 The contact radius is the length L of the compression section 1200cs. The contact radius refers to the circumferential distance between the channel surface 1201c of the body and the channel surface 1202c of the cover in contact with the cable 1220 in the compression section. The channel surfaces 1201c and 1202c form a passageway 1200p for the cable between the body and the cover. In one method, the circumferential lengths CL1 and CL2 of the first and second channel surfaces (e.g., CL1+CL2) are configured to contact the cable at a distance greater than one-third and no more than half of the cable circumference. In another method, the circumferential lengths CL1 and CL2 of the first and second channel surfaces are configured to contact the cable at a distance greater than half and no more than 80% of the cable circumference. The cable contact radius can be approximately 1 / 3 to 2 / 3 of the cable circumference.

[0110] These methods provide the optimal amount of compression for the cable, balancing holding it in place with preventing damage. For example, these methods allow for some cable bending and movement during compression. In contrast, a 100% contact radius between the body / cap and the cable can result in an overly constrained system that doesn't provide cushioning to accommodate manufacturing variations, such as differences in cable circumference.

[0111] Figure 19 A view of an attachment device 1200 with the cover 1202 removed from the body 1201, according to various embodiments, is depicted. The receiving portion 1201r of the body 1201 includes an aperture 1201h or hole through which a cable passes when it is installed in the attachment device. The presence of a gap in the receiving portion facilitates cable installation. Similarly, the cover 1202 includes an aperture 1202h through which the receiving portion passes.

[0112] In the example implementation, the diameters of orifice 1201h and orifice 1202h are approximately 0.4 inches and 0.7 inches, respectively. This is suitable for certain types of cables intended for use. The design provides a cost-effective cable retention device that allows relatively large-diameter end connectors to pass through while securely holding the smaller-diameter middle section of the cable in place.

[0113] The cover also depicts the door-shaped portion 1202g, the extension portion 1202e of the cover, and the arms 1201a1 and 1201a2 of the body 1201.

[0114] Figure 20 A view of the attachment device 1200 with the cover 1202 attached to the body 1201 according to various embodiments is depicted. The view shows how the door-shaped portion 1202g cooperates with the receiving portion to capture the cable sheath 1222 in the receiving portion 1201r.

[0115] Figure 21 A view of a cover 1202 of an attachment device 1200 according to various embodiments is depicted, showing an aperture 1202h sized to pass through a cable connector 1221. This can be a first step in installing a cable. In an example implementation, the aperture is an approximately 0.7-inch hole for the cable connector.

[0116] Figure 22A view depicting a cover 1202 attached to a body 1201 of an attachment device 1200 according to various embodiments is shown, illustrating the engagement of a gate-like portion 1202g of the cover with a receiving portion 1201r of the body 1201, a recess 1201g in the receiving portion 1201r, and a recess 1209 in the gate-like portion, without any cable. A recess or inner notch ring may be provided inside both the receiving portion 1201r and the gate-like portion 1202g, such that a corresponding flange of the cable sheath is held in the recess, and the cable sheath is thus securely held in place. Therefore, the recess in the receiving portion is used to engage with a flange in the tip of the cable sheath. After the cover is finally assembled to the body, the cable sheath and cable are securely nested in the receiving portion. In the example implementation, the cover and body are made of metal, and the cable sheath is made of rubber or plastic.

[0117] Figure 23 The lower part of the body 1201 of the attachment device 1200 according to various embodiments is depicted, showing that the cable sheath 1222 engages with the groove of the receiving portion 1201r via a flange 1222f. This can be a second step in installing the cable. Here, the flange 1222f of the cable sheath is visible. The cable sheath flange or ring sits in the receiving portion of the body for stress relief.

[0118] Note that one or more grooves can be provided inside the receiving portion and the gate-like portion, and the cable sheath can similarly have one or more flanges to sit in one or more grooves respectively, with each flange corresponding to one groove. The inside of the receiving portion and the gate-like portion can also have multiple spaced grooves to accommodate one flange of the cable sheath in different positions. Other mating mechanisms besides grooves can also be used, such as points or other protrusions that mate with notches.

[0119] Figure 24 The cover 1202 is depicted according to various embodiments and Figure 23 The body 1201 mates. This can be the third step in cable installation. This step involves moving the cover toward the body, thereby seating the cover onto the body, while ensuring that the door-shaped portion of the cover is seated with the cable sheath and receiving portion. Finally, tighten screws 1510 and 1650.

[0120] Figure 25 The diagram depicts views of an attachment device 2500 according to various embodiments, the attachment device 2500 providing... Figure 12Another example implementation of the attachment device 1200. The attachment device 2500 includes a body 2501 and a cover 2502, the cover 2502 being attachable to the bottom of the body to secure the cable 1220 and the sheath 1222 of the cable 1220. The body is elongated and accordingly has opposite first ends 2501e1 and second ends 2501e2. In this implementation, the sheath is held by a receiving portion of the body, as discussed above. However, instead of compressing the cable between the channel of the body and the cover, a bushing 2505 is held within the attachment device 2500 between the body and the cover. For example, the bushing may be a stress-relieving bushing.

[0121] In one method, the bushing includes an opening or door comprising a hinge on one side and a locking protrusion on the other side. When the door is open, a cable can be inserted into the bushing. Specifically, during assembly of the attachment device, before the cover is attached to the body, the bushing door is opened to allow the cable to be placed in the center of the bushing. The door then closes and locks around the cable to hold it in place. In one method, the bushing is positioned in the respective cutout areas 2501a and 2502a of the body and cover. Figure 26 and Figure 27 In this configuration, the bushing is held in place. The cover is attached to the body to complete the assembly of the attachment device. When the bushing is closed, force is applied to the cable, thereby holding the cable in place. In particular, the bushing may include surfaces that create curling or slight bending in the cable as shown to prevent cable movement. Thus, the cable is securely held in passage 2510 between the body and the cover.

[0122] Figure 26 Depicting various implementation methods Figure 25 A bottom view of the body 2501, cover 2502, and bushing 2505. The top portion of the bushing 2505 is held within a cut-out area 2501a (or cavity or void) in the body 2501. This cut-out area includes opposing sidewalls 2501w1 and 2501w2, which prevent the bushing from moving along the length of the attached device.

[0123] The cap 2502 includes an outlet channel 2502ec, which is located between arms 2501a1 and 2501a2 of the body when the cap is attached to the body. The outlet channel extends from an end of the cap along the length of the cap. The outlet channel 2502ec guides the cable to a first end 2501e1 of the body to position the cable in place for entry into the dental tool console.

[0124] Figure 27 Depicting various implementation methods Figure 25A top view of the body 2501, cover 2502, and bushing 2505. The bottom portion of the bushing 2505 is held within a cutout area 2502a in the cover 2502. The cutout area includes opposing sidewalls 2502w1 and 2502w2, which prevent the bushing from moving along the length of the attached device.
