Description

Technical Field

[0001] This application relates to the field of medical devices, and more specifically, to a clavicle locking plate assembly. Background Technology

[0002] Traditional clavicle plates are divided into two categories based on whether they have clavicle hooks: those without clavicle hooks and those with clavicle hooks. Clavicle plates without clavicle hooks can only be used to treat fractures, while those with clavicle hooks can treat fractures and acromioclavicular joint dislocations. However, the depth of the hooks on clavicle plates needs to be selected according to the injury. If the hook depth is not selected properly, it can easily lead to pain, limited mobility, or even shoulder impingement syndrome. Utility Model Content

[0003] The purpose of this application is to provide a clavicle locking bone plate assembly to alleviate the technical problems of limited applicability or inconvenience of use of existing clavicle plates.

[0004] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0005] The clavicle locking bone plate assembly provided by this utility model includes a clavicle plate, sutures, and two looped titanium plates;

[0006] The clavicle plate has elongated stepped holes;

[0007] The two looped titanium plates are located on both sides of the clavicle plate, with one of the looped titanium plates embedded in the stepped hole and elastically connected to the other looped titanium plate through the suture.

[0008] Furthermore, the length direction of the stepped hole extends along the length direction of the clavicle plate.

[0009] Furthermore, the stepped hole includes a mounting groove and a connecting hole, the bottom wall of the mounting groove is connected to the connecting hole, and the length of the mounting groove is greater than the length of the connecting hole, and the width of the mounting groove is equal to the width of the connecting hole;

[0010] One of the looped titanium plates is embedded in the mounting groove, and the stitch passes through the connecting hole and is elastically connected to the other looped titanium plate.

[0011] Furthermore, the looped titanium plate is fitted with the mounting groove with a clearance.

[0012] Furthermore, the thickness of the looped titanium plate embedded in the mounting groove is greater than or equal to the depth of the mounting groove.

[0013] Furthermore, the looped titanium plate embedded in the mounting groove has a first arc-shaped portion at both ends, and the mounting groove has a second arc-shaped portion corresponding to the two first arc-shaped portions at both ends.

[0014] Furthermore, at least one inner wall of the mounting groove is provided with a gripping groove.

[0015] Furthermore, each of the two looped titanium plates is provided with two wire-passing holes, which are spaced apart along the length of the looped titanium plate.

[0016] Furthermore, the two wire holes are connected by a connecting groove.

[0017] Furthermore, the two looped titanium plates are identical in shape and size.

[0018] Based on the above technical solutions, the technical effects achievable by this utility model can be analyzed as follows:

[0019] The clavicle locking plate assembly provided by this utility model includes a clavicle plate, sutures, and two looped titanium plates. The clavicle plate has an elongated stepped hole. The two looped titanium plates are located on both sides of the clavicle plate, with one looped titanium plate embedded in the stepped hole and elastically connected to the other looped titanium plate by the sutures. The shape of the looped titanium plate embedded in the stepped hole matches the shape of the elongated stepped hole, allowing the looped titanium plate to be embedded in the stepped hole, and the stepped hole acts as a limiting device for the looped titanium plate. When using this clavicle locking plate assembly, one looped titanium plate is placed in the stepped hole, and the sutures on the looped titanium plate pass through the opposite side of the coracoid process on the scapula. The other looped titanium plate is placed on the opposite side of the coracoid process, and the clavicle and coracoid process are fixed by the sutures. The clavicle plate, combined with two looped titanium plates, can treat fractures and acromioclavicular joint separations simultaneously; furthermore, the elastic fixation of the sutures maintains the micro-movement function of the acromioclavicular joint, which is conducive to restoring the anatomical relationship of the acromioclavicular joint.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

They are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0033] In the existing technology, the clavicle plate 100 without clavicle hooks can only be used to treat fractures, while the clavicle plate 100 with clavicle hooks can treat fractures and acromioclavicular joint dislocations. However, the clavicle plate 100 with clavicle hooks needs to select an appropriate hook depth according to the injury. If the hook depth is not selected appropriately, it can easily lead to pain, limited mobility, or shoulder impingement syndrome in patients.

[0034] In view of this, see Figures 1 to 6 One looped titanium plate 200 is omitted in the figure. The clavicle locking bone plate assembly provided in this embodiment of the present invention includes a clavicle plate 100, sutures and two looped titanium plates 200; the clavicle plate 100 has an elongated stepped hole 110; the two looped titanium plates 200 are respectively located on both sides of the clavicle plate 100, one of the looped titanium plates 200 is embedded in the stepped hole 110 and is elastically connected to the other looped titanium plate 200 through the sutures.

[0035] Specifically, see Figure 4 and Figure 5 The clavicle plate 100 is a plate-like structure extending at both ends. Its side closer to the bone is concave to fit snugly against the bone of the clavicle, while its side farther from the bone is convex, presenting a smooth convex surface. When the clavicle is fractured, the clavicle plate 100 is used to fix it to the clavicle, connecting the bone structure. For further fitting snugly against the clavicle bone, see [link to relevant documentation]. Figure 4 The clavicle plate 100 has an S-shaped curved structure in top view, see [reference]. Figure 5 It exhibits a certain degree of twist along its extension direction on the formal surface.

[0036] The looped titanium plate 200, embedded within the stepped hole 110, is shaped to match the elongated stepped hole 110, allowing the looped titanium plate 200 to be fitted within it, while the stepped hole 110 serves to limit its position. When using this clavicle locking plate assembly, one looped titanium plate 200 is placed within the stepped hole 110, with sutures on it passing through the opposite side of the coracoid process on the scapula. Another looped titanium plate 200 is placed on the opposite side of the coracoid process, and the clavicle and coracoid process are fixed together by sutures. The clavicle plate 100, combined with two looped titanium plates 200, can simultaneously treat fractures and acromioclavicular joint separation. Furthermore, the elastic fixation using sutures maintains the micro-movement function of the acromioclavicular joint, which is conducive to restoring the anatomical relationship of the acromioclavicular joint. In addition, the clavicle locking plate assembly includes two looped titanium plates 200, one of which is placed in the stepped hole 110 of the clavicle plate 100. The position of the looped titanium plate 200 relative to the stepped hole 110 can be finely adjusted, and after adjustment, it is elastically fixed using sutures.

[0037] The structure and shape of the clavicle locking plate assembly are described in detail below:

[0038] In an optional embodiment of this utility model, the length direction of the stepped hole 110 extends along the length direction of the clavicle plate 100.

[0039] Specifically, see Figure 1 and Figure 2 The stepped hole 110 is located on the right side of the clavicle plate 100.

[0040] The length of the stepped hole 110 extends along the length of the clavicle plate 100 to avoid the clavicle plate 100 having low strength due to the width of the position where the stepped hole 110 is provided, and also to avoid the problem of the clavicle plate 100 being easy to deform.

[0041] In an optional embodiment of this utility model, the stepped hole 110 includes a mounting groove 111 and a connecting hole 112. The bottom wall of the mounting groove 111 is connected to the connecting hole 112, and the length of the mounting groove 111 is greater than the length of the connecting hole 112. The width of the mounting groove 111 is equal to the width of the connecting hole 112. One of the looped titanium plates 200 is embedded in the mounting groove 111, and the stitching passes through the connecting hole 112 and is elastically connected to the other looped titanium plate 200.

[0042] Specifically, the length of the mounting groove 111 extends along the length of the clavicle plate 100, and the lower surface of the looped titanium plate 200 embedded in the stepped hole 110 fits against the bottom wall of the mounting groove 111, so that the mounting groove 111 can limit the looped titanium plate 200.

[0043] The length of the mounting groove 111 is greater than the length of the connecting hole 112, so that the looped titanium plate 200 can fit against the bottom wall of the mounting groove 111; the width of the mounting groove 111 is equal to the width of the connecting hole 112, so that the cross-sectional area of ​​the connecting hole 112 is large, which facilitates the use of stitches to elastically connect the two looped titanium plates 200.

[0044] In an optional embodiment of this utility model, the titanium plate 200 with loops is clearance-fitted with the mounting groove 111.

[0045] Specifically, the clearance fit between the looped titanium plate 200 and the mounting groove 111 means that there is a certain amount of gap between them, which is used for fine-tuning. Furthermore, the looped titanium plate 200 and the mounting groove 111 have a small amount of gap in both the length and width directions, allowing for minor adjustments in both directions.

[0046] The looped titanium plate 200 and the mounting groove 111 are fitted together with a clearance so that they have a gap that can be used for fine adjustment.

[0047] In an optional embodiment of this utility model, the thickness of the looped titanium plate 200 embedded in the mounting groove 111 is greater than or equal to the depth of the mounting groove 111.

[0048] Specifically, in this embodiment, see Figure 3 The thickness of the looped titanium plate 200 embedded in the mounting groove 111 is equal to the depth of the mounting groove 111. That is, when the looped titanium plate 200 is embedded in the mounting groove 111, the lower surface of the looped titanium plate 200 is in contact with the bottom wall of the mounting groove 111, and the upper surface is flush with the upper surface of the clavicle plate 100. If the thickness of the looped titanium plate 200 is less than the depth of the mounting groove 111, when the looped titanium plate 200 is embedded in the mounting groove 111, the upper surface of the looped titanium plate 200 is lower than the surface of the clavicle plate 100, resulting in low strength of the clavicle plate 100 and easy deformation of the clavicle plate 100. If the thickness of the looped titanium plate 200 is greater than the depth of the mounting groove 111, when the looped titanium plate 200 is embedded in the mounting groove 111, the upper surface of the looped titanium plate 200 protrudes from the surface of the clavicle plate 100, which can improve the strength of the clavicle plate 100. However, there is a problem that the part of the looped titanium plate 200 protruding from the clavicle plate 100 rubs against the human body, resulting in reduced comfort.

[0049] The thickness of the looped titanium plate 200 embedded in the mounting groove 111 is equal to the depth of the mounting groove 111 so that the clavicle plate 100 has high strength and is not easily deformed.

[0050] In an optional embodiment of this utility model, the two ends of the looped titanium plate 200 embedded in the mounting groove 111 are provided with first arc-shaped portions 210, and the two ends of the mounting groove 111 are provided with second arc-shaped portions corresponding to the two first arc-shaped portions 210.

[0051] Specifically, the two ends of the looped titanium plate 200 protrude outward to form two first arc-shaped portions 210; the two ends of the mounting groove 111 are recessed outward to form two second arc-shaped portions.

[0052] The two ends of the looped titanium plate 200 have a first arc-shaped portion 210 to avoid accidental injury during operation.

[0053] In an optional embodiment of this utility model, at least one inner wall of the mounting groove 111 is provided with a gripping groove 113.

[0054] Specifically, in this embodiment, each of the two inner walls of the mounting groove 111 extending along the length of the mounting groove 111 is provided with a gripping groove 113. Preferably, the gripping groove 113 is located in the middle of the mounting groove 111.

[0055] The gripping slot 113 is connected to the mounting slot 111, which facilitates the placement or removal of the looped titanium plate 200.

[0056] In an optional embodiment of this utility model, the clavicle plate 100 has a plurality of locking and pressurizing holes 120 spaced apart along the length of the clavicle plate 100, and the locking and pressurizing holes 120 are waist-shaped. The maximum distance between the two gripping grooves 113 is not greater than the maximum width of the locking and pressurizing hole 120.

[0057] Specifically, see Figure 4 The maximum distance between the two gripping slots 113 is a1, and the maximum width of the locking pressure hole 120 is a2, where a1≤a2; preferably, a1=a2, which can make the clavicle plate 100 strong and ensure that the clavicle plate 100 is not easily deformed.

[0058] The maximum distance between the two gripping slots 113 is equal to the maximum width of the locking pressure hole 120, ensuring that the cross-sectional area of ​​the clavicle plate 100 remains consistent, ensuring the strength of the clavicle plate 100 and ensuring that the clavicle plate 100 is not easily deformed.

[0059] In an optional embodiment of this utility model, both the inner wall of the mounting groove 111 and the outer wall of the looped titanium plate 200 are set as inclined surfaces.

[0060] Specifically, the four inner walls of the mounting groove 111 are all configured as first inclined surfaces, which gradually slope away from the center of the mounting groove 111 from bottom to top; the four outer walls of the looped titanium plate 200 are all configured as second inclined surfaces, which gradually slope away from the center of the looped titanium plate 200 from bottom to top.

[0061] The first and second inclined planes are matched to serve as guides.

[0062] In an optional embodiment of this utility model, each of the two looped titanium plates 200 is provided with two wire-passing holes 220, and the two wire-passing holes 220 are spaced apart along the length direction of the looped titanium plates 200.

[0063] Specifically, see Figure 6 The two wire holes 220 have different shapes; one wire hole 220 is circular, and the other wire hole 220 is pear-shaped.

[0064] Two thread holes 220 are used to allow the suture to pass through, thereby enabling the two looped titanium plates 200 to be elastically connected by the suture.

[0065] In an optional embodiment of this utility model, the two wire holes 220 are connected by a connecting groove 230.

[0066] The connecting groove 230 allows the suture to be embedded in the looped titanium plate 200, avoiding the problem of the suture protruding.

[0067] In an optional embodiment of this utility model, the two looped titanium plates 200 have the same shape and size.

[0068] Specifically, the two looped titanium plates 200 are identical in shape, size, and structure. Furthermore, in this embodiment, the looped titanium plates 200 are made of titanium alloy, while the clavicle plate 100 is made of pure titanium.

[0069] When using this clavicle locking plate assembly, there is no need to distinguish between the two looped titanium plates 200, making operation convenient and fundamentally avoiding the problem of incorrect use.

[0070] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0071] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
