Abstract
Description
Technical Field
[0001] This application is based on and claims the benefit of priority from Korean Patent Application No. 10-2023-0111582 filed on August 24, 2023, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein in its entirety by reference.
[0002] The present disclosure relates to a lifting surgical suture, and more particularly, to a lifting surgical suture for preventing depression after cosmetic surgery, particularly thread lift surgery. Background Art
[0003] Typically, human facial skin ages over time, leading to stretching and sagging of the skin and the appearance of wrinkles. Numerous methods exist for preventing aging and repairing facial skin, such as cosmetic injectable therapies (typically including Botox and fillers), thread lifts, and surgical facelifts.
[0004] Among them, botulinum toxin and fillers can effectively eliminate wrinkles and replenish the lost volume in sagging areas to a certain extent, but they have little or no effect on lifting and firming aging skin.
[0005] Furthermore, surgical procedures such as facelifts are invasive procedures involving incisions in the facial skin and access to the tissue, and require lengthy recovery times.
[0006] Therefore, thread lifts are the preferred procedure because they are less visible on the skin, are minimally invasive, and have a shorter recovery time, allowing for a quicker return to daily life.
[0007] The thread lift is performed by inserting a lifting suture into the subcutaneous layer of sagging skin or loose skin and pulling the lifting suture in a desired direction to lift the skin.
[0008] In this case, the tensile strength of the barbed (barb-like protrusions) lifting suture can help prevent wrinkling and sagging of the skin in the area where the lifting suture is inserted, and promote collagen production in the dermis, thereby improving skin elasticity.
[0009] However, in many cases, barbed sutures can cause dimpling or wrinkling of the skin when the suture is pulled for a lift. Summary of the Invention

[0061] Figure 1 FIG. 1 is a schematic diagram of a surgical suture for lifting according to a first embodiment of the present disclosure. Figure 2 To show the coupling to Figure 1 The thread body of the needle in the figure, Figure 3 for Figure 1 A perspective view of a controller in a surgical suture for lifting, Figure 4 for Figure 1 A perspective view of a stopper coupled to a plurality of protrusions and a controller in a surgical suture for lifting, Figure 5 Based on Figure 4 A perspective view of a variation of a lifting surgical suture having a stop coupled to a plurality of protrusions and a controller, and Figure 6 Based on Figure 4 A perspective view of a stop coupled to a plurality of protrusions and a controller in another variation of a lifting surgical suture.
[0062] Reference Figures 1 to 6 The lifting surgical suture thread 10 according to the first embodiment of the present disclosure includes a thread body 100 , a protruding portion 200 , a stopper 300 , and a controller 400 .
[0063] The thread body 100 is a thread that is inserted into the skin of a human body (e.g., a human face) for a face lift. Here, face lift refers to a procedure that involves inserting the face lift suture 10 into the subcutaneous layer of sagging or loose skin and pulling the face lift suture in a desired direction to lift and tighten aging skin.
[0064] Reference Figure 2 , the needle 500 is coupled to at least one of the two ends of the thread body 100. In addition, for example, the needle 500 penetrates the skin of a person's face and performs lifting while the thread body 100 coupled to the needle 500 remains in the facial skin. The lifting technique will be described in detail below (see below Figure 16 ).
[0065] Reference Figure 1 and Figure 2 A protrusion 200 (e.g., a plurality of protrusions 200a, 200b, 200c) protruding from the tether body 100 is formed at the tether body 100. Furthermore, stoppers 300b, 300c, respectively coupled to the protrusions 200b, 200c, are coupled and fixed to the tether body 100. Furthermore, the controller 400 is movably positioned at the tether body 100 between the plurality of stoppers 300 (e.g., a first stopper 300b and a second stopper 300c).
[0066] A plurality of protrusions 200 are formed at the wire body 100 such that they protrude from the wire body 100. The protrusions 200 may be integrally formed with the wire body 100, but are not necessarily limited thereto.
[0067] In addition, refer to Figure 1 and Figure 4 , the protrusion 200 is coupled to the stopper 300. Figure 1, the plurality of protrusions 200b, 200c are respectively coupled to the plurality of stoppers 300, for example, the first stopper 300b and the second stopper 300c. That is, the protrusion 200b is coupled to the first stopper 300b, and the protrusion 200c is coupled to the second stopper 300c. The plurality of protrusions 200a, 200b, 200c are spaced apart and coupled to the wire body 100. Here, referring to Figure 1 , the stopper 300 may not be coupled to the protrusions 200 a located at both ends of the wire body 100 .
[0068] The protrusion 200 may have various shapes. Figure 7 The protrusion 200 may include a pair of protrusions 210 and 220 , which may extend from the stopper 300 at a predetermined angle θ1 and be symmetrically formed with respect to the wire body 100 .
[0069] That is, the pair of protrusions 210, 220 may be formed in a barb shape such that they are spread apart from each other from the stopper 300. However, the shape of the protrusion 200 is provided as an embodiment and is not limited thereto.
[0070] When the pair of protrusions 210 , 220 are formed in a barb shape, the pair of barb-shaped protrusions 210 , 220 may cause skin to sag or wrinkle during pulling of the wire body 100 .
[0071] Reference Figure 1 and Figure 2 In order to prevent the formation of depressions, the lifting surgical suture thread 10 according to the first embodiment of the present disclosure includes a plurality of stoppers 300 and a plurality of controllers 400. The stoppers 300 can selectively pass through the through holes 410 formed in the controller 400 (see Figure 3 and Figure 4 ), and when the stopper 300 passes through the through hole 410, the pair of protrusions 210, 220 coupled to the stopper 300 also pass through the through hole 410. In this case, the angle θ1 formed by the pair of protrusions 210, 220 (see Figure 7 ) decrease (see Figure 10 That is, the pair of protrusions 210, 220 that are spread out in a barb shape come closer to each other when passing through the through hole 410 of the controller 400 (see Figure 10 θ2 in FIG), therefore, the skin wrinkling problem caused by the pair of protrusions 210 and 220 is solved, thereby preventing the formation of depressions.
[0072] Reference Figure 1, the plurality of protrusions 200a, 200b, 200c may be arranged at regular intervals on the wire body 100. However, the intervals of the plurality of protrusions 200a, 200b, 200c may not be regular, and the intervals of the plurality of protrusions 200a, 200b, 200c may be different if necessary.
[0073] The material of the protrusion 200 may be the same as that of the wire body 100 , but the protrusion 200 and the wire body 100 may be made of different materials.
[0074] Each of the plurality of stoppers 300 is coupled to each of the plurality of protrusions 200a, 200b, 200c. The stoppers 300 may be formed in various shapes, for example, Figures 1 to 4 As shown, the stopper 300 may have an elliptical or oval cross-sectional shape, but the shape of the stopper 300 is not limited thereto.
[0075] For example, the cross-sectional shape of the stopper 300 may include a square or rectangular, circular or triangular shape, and the through hole 410 of the controller 400 may have a shape consistent with the cross-sectional shape of the stopper 300. However, for ease of description, the first embodiment describes the stopper 300 having an elliptical or oval cross-sectional shape, and the second embodiment will hereinafter describe the stopper 300 having a square or rectangular cross-sectional shape.
[0076] The stopper 300 may be made of an elastic material. When the cable body 100 is pulled, the stopper 300 coupled to the cable body 100 moves toward the controller 400 and is blocked by the controller 400. Here, when the force pulling the cable body 100 is less than a preset value, the stopper 300 cannot pass through the controller 400.
[0077] However, in the case where the pair of protrusions 210 and 220 wrinkles the skin, when the force pulling the wire body 100 is equal to or greater than a preset size, the stopper 300 is elastically deformed by the force acting on the stopper 300 so as to pass through the controller 400.
[0078] Here, when the stopper 300 passes through the controller 400 , the protrusion 200 coupled to the stopper 300 passes through the controller 400 together with the stopper 300 .
[0079] Specifically, if Figure 1 As shown, the controller 400 is located between the plurality of stoppers 300 (eg, the first stopper 300 b and the second stopper 300 c ).
[0080] In a normal state, the first stopper 300b and the second stopper 300c prevent the controller 400 from passing over the first stopper 300b and the second stopper 300c. That is, unless a force equal to or greater than a preset magnitude is applied, the controller 400 is blocked by the stopper 300 and cannot pass over the stopper 300.
[0081] However, when a preset force is applied, the stopper 300 passes through the through hole 410 formed in the controller 400. In this case, the protrusion 200 coupled to the stopper 300 passes through the through hole 410 formed in the controller 400 together with the stopper 300.
[0082] In addition, when the protrusion 200 passes through the through hole 410 formed in the controller 400, the pair of protrusions 210, 220 spread out in a barb shape are closer to each other. Therefore, the problem of skin sag or wrinkling caused by the pair of protrusions 210, 220 can be solved.
[0083] The controller 400 may have various shapes of the through hole 410. Figure 1 As shown, the controller 400 can be connected to the through hole 410 (see Figure 3 or Figure 4 ) is positioned at the cable body 100 between a plurality of stoppers 300 (e.g., the first stopper 300b and the second stopper 300c). That is, when the cable body 100 passes through the through hole 410 of the controller 400, the controller 400 can move between the first stopper 300b and the second stopper 300c of the cable body 100.
[0084] As described above, the through hole 410 formed in the controller 400 selectively allows the stopper 300 to pass therethrough. That is, the stopper 300 can selectively pass through the through hole 410. In addition, when the stopper 300 passes through the through hole 410 of the controller 400, the protrusion 200 coupled to the stopper 300 also passes through the through hole 410.
[0085] Here, selectively passing means that in a normal state, the stopper 300 cannot pass through the through hole 410 formed in the controller 400, but when a force equal to or greater than a preset force is applied, the stopper 300 passes through the through hole 410 formed in the controller 400.
[0086] Reference Figure 1 As described above, the controller 400 is movable on the cable body 100, and in particular, the controller 400 is configured to move between a first stopper 300b and a second stopper 300c adjacent thereto among a plurality of stoppers 300 coupled to the cable body 100. Furthermore, as described above, in a normal state, the controller 400 is blocked by the stoppers 300 and cannot pass through the stoppers 300.
[0087] When tissue adhesion occurs after the first lift, the controller 400 can work together with the multiple protrusions 200a, 200b, and 200c to tighten the aged skin. That is, the controller 400 can effectively support a large amount of tissue due to its large surface area, and achieve a double pull together with the protrusions 200 to prevent slippage, thereby enhancing the lifting function and improving sustainability.
[0088] The size of the through hole 410 formed in the controller 400 may be the same or different from one end to the other. Figure 3 , the size of the through hole 410 is different from one end to the other end of the controller 400, but is not limited thereto.
[0089] That is, as described below, when the stop portion 300 is made of an elastic material and the size of the through hole 410 of the controller 400 is the same, as long as the stop portion 300 can pass through the through hole 410 of the controller 400 through the elastic deformation of the stop portion 300, the size of the through hole 410 of the controller 400 can be the same from one end to the other.
[0090] Reference Figure 3 and Figure 4 , the through hole 410 formed in the controller 400 may include a first outer hole 411, an inner hole 412, and a second outer hole 413. Here, the controller 400 may have a truncated cone (ie, a cone with a top cut off) shape, but is not limited thereto.
[0091] Figure 4 The diagram shows that the size (here, diameter) decreases from the first outer hole 411 through the inner hole 412 to the second outer hole 413 , but the present invention is not limited thereto.
[0092] Reference Figure 5 , as Figure 4 In a variation of the present invention, the first outer hole 411, the inner hole 412 and the second outer hole 413 may have the same size. Figure 6 , as Figure 4 In another variation, the size can increase from the first outer hole 411 through the inner hole 412 to the second outer hole 413. When the stopper 300 is made of elastic material, even if the controller 400 has Figure 5 and Figure 6 The shape shown in FIG. 3 is a diagram showing a shape of a stopper 300. The stopper 300 may also selectively pass through a through hole 410 formed in the controller 400. Figure 6 .
[0093] Reference Figure 3, the first outer hole 411 is formed at any one outer side of the controller 400. In addition, the inner hole 412 is connected to the first outer hole 411 and formed on the inner side of the controller 400. That is, the inner hole 412 is formed between the first outer hole 411 and the second outer hole 413. In addition, the second outer hole 413 is formed at the opposite outer side of the controller 400, so that the second outer hole is located opposite to the first outer hole 411.
[0094] Here, the stopper 300 may have various sizes to fit the through hole 410 of the controller 400. For example, referring to Figure 4 , the stopper 300 may be smaller than the first outer hole 411 but larger than the inner hole 412. In this case, when the wire body 100 is pulled with a force less than a preset force, the stopper 300 moves into the first outer hole 411 but gets stuck in the inner hole 412 and cannot pass through the through hole 410.
[0095] However, when the wire body 100 is pulled with a force equal to or greater than a preset force, the stopper 300 of the elastic material may pass through the through hole 410 while being elastically deformed.
[0096] As a variation, the stopper 300 may be smaller than the first outer hole 411 but equal to the inner hole 412. As another variation, the stopper 300 may be smaller than the first outer hole 411 and smaller than the inner hole 412. As yet another variation, the stopper 300 may be smaller than the first outer hole 411, smaller than the inner hole 412, and smaller than the second outer hole 413.
[0097] However, in actual use during human surgery, when the wire body 100 is pulled, the wire body 100 does not move precisely through the center of the through hole 410 of the controller 400, but rather moves up and down or left and right based on the center of the through hole 410. Therefore, in the above-mentioned modification, for example, even in an embodiment in which the stopper 300 is smaller than the first outer hole 411, smaller than the inner hole 412, and smaller than the second outer hole 413, the stopper 300 can serve as a stopper to prevent the controller 400 from passing through the stopper 300 when contacting the inner surface of the controller 400. Therefore, the stopper 300 may have different sizes.
[0098] Meanwhile, as another variation, referring to Figure 6 , the stopping portion 300 may be larger than the first outer hole 411 .
[0099] When the stopper 300 is larger than the first outer hole 411, the stopper 300 cannot move into the through hole 410 through the first outer hole 411. However, as described above, when the stopper 300 is made of an elastic material, even the stopper 300 that is larger than the first outer hole 411 can pass through the through hole 410 because the stopper 300 elastically deforms when the wire body 100 is pulled by a force equal to or greater than a preset force.
[0100] In addition, as another variation, the stopper 300 may have the same size as the first outer hole 411. When the stopper 300 has the same size as the first outer hole 411, the stopper 300 can pass through the through hole 410 because the stopper 300 elastically deforms when the wire body 100 is pulled by a force equal to or greater than a preset force.
[0101] Meanwhile, the wire body 100 may be made of a biodegradable material that degrades in the human body or a non-degradable material or a non-absorbable material. In addition, the controller 400 is preferably made of a biodegradable polymer to maximize collagen regeneration, but is not limited thereto.
[0102] For example, the thread body 100 may be made of an absorbent polymer or a non-absorbent polymer. For example, the biodegradable material may include polylactic-glycolic acid (PLGA), polydioxanone (PDO), or poly-L-lactic acid (PLLA) or polycaprolactone (PCL) synthesized by mixing polylactic acid with glycolic acid.
[0103] PLLA is rigid and lasts a long time. PLGA reduces rigidity, resulting in a lesser foreign body sensation. PDO is softer, causing minimal foreign body sensation. PCL, on the other hand, is less rigid, stimulates collagen production, and lasts a long time, for example, approximately two years.
[0104] Here, the thread body 100 and the controller 400 may be made of the same material or different materials. For example, when the thread body 100 and the controller 400 are made of different materials, the thread body 100 may include PLLA and the controller 400 may include PCL. Alternatively, when the thread body 100 and the controller 400 are made of different materials, the thread body 100 may include PCL and the controller 400 may include PLLA. Alternatively, various biodegradable materials such as PLGA or PDO may be used together to manufacture the thread body 100 and the controller 400.
[0105] However, the materials of the wire body 100 and the controller 400 are not limited thereto.
[0106] Figures 7 to 12 To show that the stop portion passes through Figure 1 Diagram of the through-hole process of the controller.
[0107] Reference Figure 7 and Figure 8 , the stopper 300 moves into the controller 400 through the first outer hole 411 of the controller 400. In this case, the size of the first outer hole 411 is larger than the size of the stopper 300. Therefore, the stopper 300 can easily enter the first outer hole 411 (see Figure 8 ).
[0108] Reference Figure 9 , the stopper 300 is stuck in the inner hole 412 of the controller 400. In this case, when the wire body 100 is pulled with a force less than a preset force, the stopper 300 cannot pass through the through hole 410 of the controller 400.
[0109] However, when the wire body 100 is pulled with a force equal to or greater than a preset force, the stopper 300 is Figure 10 elastic deformation, and as Figure 11 The controller 400 is shown completely removed through the second outer hole 413 . Figure 12 Two controllers 400 are shown placed between two stoppers 300 by moving the controllers 400 out of the stoppers 300 .
[0110] In this case, the pair of protrusions 210, 220 coupled to the stopper 300 and spread out in a barb shape come closer to each other when passing through the controller 400. In addition, as described above, the skin indentation problem is solved.
[0111] Specifically, the stopper 300 moves into the controller 400 through the first outer hole 411, passes through the inner hole 412, and moves out of the controller 400 through the second outer hole 413. That is, the stopper 300 that moves through the first outer hole 411 into the inner hole 412 moves out of the controller 400 through the second outer hole 413. In this case, the protrusion 200 coupled to the stopper 300 also moves through the first outer hole 411 into the inner hole 412 and moves out of the controller 400 through the second outer hole 413.
[0112] Here, as Figure 9 As shown, a pair of protrusions 210, 220 are extended in a barb shape, and contact the inner surface of the controller 400 while passing through the first outer hole 411, the inner hole 412 and the second outer hole 413. Figure 9 As shown, since the diameter of the controller 400 decreases from the first outer hole 411 to the second outer hole 413 through the inner hole 412, the pair of protrusions 210 and 220 passing through the through hole 410 gradually approach each other, as shown in FIG. Figure 10 As shown. Thus, the problem of skin dimpling is solved.
[0113] At the same time, refer to Figure 1 Before the stopper 300 passes through the through hole 410 of the controller 400, each controller 400 is located between two stoppers 300. For example, Figure 1 In the embodiment, a controller 400 is located between the first stop portion 300b and the second stop portion 300c.
[0114] However, when any one of the stoppers 300 passes Figures 7 to 11 When the controller 400 passes through the through hole 410, the two controllers 400 are placed between the two stop parts 300. Figure 12 shown.
[0115] Figures 13 to 17 To show that the stop portion passes through Figure 6 Diagram of the through-hole process of the controller.
[0116] Reference Figure 6 The size increases from the first outer hole 411 through the inner hole 412 to the second outer hole 413.
[0117] Reference Figure 13 , the size of the first outer hole 411 is smaller than the size of the stopper 300. However, when the stopper 300 is made of elastic material, referring to Figure 14 and Figure 15 , the stopper 300 can move into the controller 400 through the first outer hole 411 when elastically deformed. In addition, the pair of protrusions 210 and 220 coupled to the stopper 300 come into contact with the controller 400 while passing through the controller 400 and come closer to each other, thereby solving the problem of skin indentation. In addition, as Figure 16 As shown, the stopper 300 and the pair of protrusions 210 , 220 are moved out of the controller 400 through the second outer hole 413 .
[0118] At the same time, as mentioned above Figure 12 As described above, when any stop portion 300 passes Figures 13 to 16 When the controller 400 passes through the through hole 410, the two controllers 400 are placed between the two stop parts 300. Figure 17 shown.
[0119] Figure 18 A diagram schematically illustrates a process of performing a lift surgery on human facial skin using the lift surgical suture according to the first embodiment of the present disclosure.
[0120] Reference Figure 18 , a pair of needles 500 coupled to the wire body 100 penetrate the facial skin and enter the subcutaneous layer or the underlying musculoaponeurotic layer (SMAS). Figure 18 In the embodiment of the present invention, scissors are used to remove the needle 500 and the remaining portion 150 of the thread body 100, leaving the starting point P1 and the end point P2 where the needle 500 exits the skin.
[0121] That is, only the lifting surgical suture between the starting point P1 and the end point P2 remains in the human body. Meanwhile, before removing the pair of needles 500, when the pair of needles 500 are pulled, the protrusions 200 generate tension, and the skin is lifted and tightened by the tension.
[0122] However, in this case, the pair of barbed protrusions 210, 220 may cause the skin to sag or wrinkle.
[0123] Here, the surgeon may appropriately adjust the starting point P1 portion and the pulling force of the pair of needles 500 to allow the stopper 300 to pass through the through hole 410 of the controller 400 .
[0124] In this case, as the stopper 300 passes through the through hole 410 of the controller 400 and the protrusion 200 coupled to the stopper 300 also passes through the through hole 410, the pair of protrusions 210 and 220 gradually approach each other, and thus the skin indentation problem can be solved.
[0125] Figure 19 FIG2 is a schematic diagram of a lifting surgical suture according to a second embodiment of the present disclosure. Figure 20 for Figure 19 A perspective view of a controller in a surgical suture for lifting, and Figure 21 for Figure 19 A perspective view of a stop coupled to multiple protrusions and a controller in a lifting surgical suture.
[0126] The second embodiment of the present disclosure differs from the first embodiment in the shape of the stopper 300. The same descriptions as those of the first embodiment are replaced with the above descriptions of the first embodiment. In addition, the descriptions of the second embodiment applicable to the first embodiment can also be applied to the first embodiment.
[0127] Reference Figure 19 and Figure 21 , the stop portion 300 has a square or rectangular cross-sectional shape. Figure 20 and Figure 21 , the through hole 410 formed in the controller 400 has a square or rectangular cross-sectional shape to be consistent with the shape of the stopping portion 300 .
[0128] Also in the second embodiment, in a normal state, the stopper 300 prevents the controller 400 from passing through the stopper 300. That is, the controller 400 is blocked by the stopper 300 and cannot pass through the stopper 300 unless a preset force is applied.
[0129] However, when a force equal to or greater than a preset force is applied, the stopper 300 passes through the through hole 410 formed in the controller 400 while being elastically deformed.
[0130] Furthermore, the second embodiment requires not only a preset force but also shape matching. Unlike the first embodiment, a locking mechanism can be applied to the second embodiment. Specifically, the cross-sectional shape of the stopper 300 and the cross-sectional shape of the through-hole 410 formed in the controller 400 can be matched, for example, in a square or rectangular shape to allow the stopper 300 to pass through the through-hole 410 of the controller 400. However, the cross-sectional shape of the stopper 300 and the cross-sectional shape of the through-hole 410 formed in the controller 400 are not limited to square or rectangular shapes and can include a wider variety of shapes.
[0131] Specifically, when the surgeon aligns the stopper 300 with the through hole 410 of the controller 400 through fine adjustment as described above and pulls it up with a force equal to or greater than a preset force, the stopper 300 passes through the through hole 410 of the controller 400 .
[0132] In this case, the protrusion 200 coupled to the stopper 300 passes through the through hole 410 formed in the controller 400 together with the stopper 300, and the pair of protrusions 210 and 220 spread out in a barb shape come closer to each other when passing through the through hole 410. Therefore, the skin wrinkling problem caused by the protrusion 200 can be solved, and the skin sag problem can be solved.
[0133] The surgical suture for lifting according to various embodiments of the present disclosure has the following effects.
[0134] First, it has the effect of preventing the skin from dimpling or wrinkling that occurs during lifting surgery.
[0135] In addition, when only the barbed protrusion 200 is present on the wire body 100, the barbed protrusion 200 may penetrate into the skin tissue when the wire body 100 is pulled, thereby causing pain. However, the lifting surgical suture 10 according to each embodiment of the present disclosure can achieve force distribution of the barbed protrusion 200 and the streamlined controller 400, thereby enhancing the lifting function while reducing pain.
[0136] In addition, there is an effect of promoting collagen production using different materials, and in addition to the lifting function, it is also possible to increase volume. For example, unlike the thread body 100, when the material of the controller 400 is made of a biodegradable material to maximize collagen production, the rejuvenation effect intended for lifting can be maximized.
[0137] Furthermore, during the product production process, injection molding or press molding can be utilized, and the controller in each region can pass through the stop region, thereby reducing manual operations, thereby achieving automation, reducing manufacturing time, and allowing for mass production, thereby reducing production costs. In this case, the wire body 100 can be integrally formed with the protrusion 200 and the stopper 300, but is not necessarily limited to this.
[0138] For convenience of description, terms indicating directions such as up, down, left, and right are used, but it is obvious to those skilled in the art that these terms may change according to positions of the elements described or observers.
[0139] Although the present disclosure has been described above with respect to a certain number of embodiments and drawings, the present disclosure is not limited thereto, and it is apparent that various changes and modifications may be made thereto by those skilled in the art within the technical aspects of the present disclosure and the appended claims and their equivalents. Therefore, it should be understood that the disclosed embodiments are provided for illustrative purposes only and not for limitation. In other words, the true technical scope of the present disclosure is defined by the appended claims, and the present disclosure should be understood to encompass all differences within the scope of equivalents.
