Technical Field

[0001] This utility model belongs to the field of clavicle plate technology, specifically a locking S-shaped seven-hole clavicle plate proximal fixation structure. Background Technology

[0002] Clavicle fractures are a common type of fracture in clinical practice, especially in high-energy trauma. For proximal clavicle fractures, effective fixation is crucial for fracture healing and recovery of shoulder joint function. The S-shaped seven-hole clavicle plate, due to its unique shape design, can better conform to the physiological curvature of the clavicle, while the optimization of the proximal fixation structure is the key to ensuring fixation effectiveness.

[0003] When using the existing S-shaped seven-hole clavicle plate, the proximal end of the plate needs to be adjusted according to the position and orientation of different fracture fragments during fixation. This has certain limitations and cannot effectively adapt to the position of the fracture fragments.

[0004] Therefore, a locking S-shaped seven-hole clavicle plate proximal fixation structure is proposed to address the above problems. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 5 As shown, this utility model provides a locking S-shaped seven-hole clavicle steel plate proximal fixation structure, including an S-shaped seven-hole clavicle steel plate body 1, and a front-end fixing adjustment component 2 installed on the surface of the S-shaped seven-hole clavicle steel plate body 1.

[0025] The front-end fixing adjustment component 2 includes an adjustment groove 21. The proximal end of the S-shaped seven-hole clavicle plate body 1 is provided with an adjustment groove 21. A movable rod 22 is rotatably connected inside the adjustment groove 21. A fixing block 23 is installed on the surface of the movable rod 22. A locking screw 24 is threaded into the threaded hole on the surface of the fixing block 23. One end of the movable rod 22 passes through the S-shaped seven-hole clavicle plate body 1 and extends to the top of the S-shaped seven-hole clavicle plate body 1, and is connected to the handle plate 25 set on the top of the S-shaped seven-hole clavicle plate body 1. A damping component 3 is installed inside the S-shaped seven-hole clavicle plate body 1, so that when fixing the proximal end of the S-shaped seven-hole clavicle plate body 1, the angle position of the proximal fixation can be adjusted, so that it can be adjusted according to the position and direction of different fracture fragments, and further improve the adaptation effect of the S-shaped seven-hole clavicle plate body 1.

[0026] Specifically, a safety pin 26 is slidably connected in the socket on the surface of the handle plate 25. One end of the safety pin 26 passes through the handle plate 25 and is inserted into the slot on the surface of the S-shaped seven-hole clavicle steel plate body 1. This locks the fixed block 23 after adjustment, preventing the fixed block 23 from rotating during use and affecting the normal use of the S-shaped seven-hole clavicle steel plate body 1.

[0027] like Figures 1 to 5 As shown, the surface of the S-shaped seven-hole clavicle steel plate body 1 is provided with multiple slots for fixing according to the adjusted position.

[0028] Furthermore, a washer is provided between the locking screw 24 and the fixing block 23, and the washer is made of "medical silicone". The function of the washer is to increase the friction between the locking screw 24 and the fixing block 23 and prevent the locking screw 24 from loosening during use.

[0029] It is worth noting that the locking screw 24 is made of titanium alloy, which improves the strength of the locking screw 24.

[0030] like Figures 1 to 5 As shown, the damping assembly 3 includes a locking strip 31. The locking strip 31 is symmetrically installed inside the adjustment groove 21. A damping strip 32 is installed in the groove opened on the surface of the locking strip 31. The damping strip 32 fits against the surface of the movable rod 22. The damping strip 32 can dampen the movable rod 22, preventing the fixed block 23 from rotating too much, so as to adjust the angle of the fixed block 23 more accurately and further improve the use effect of the device.

[0031] It is worth emphasizing that the locking bar 31 is made of "metal elastic steel". Operators can pry open the locking bar 31 to deform it, thereby reducing the damping of the movable rod 22. This allows the position of the fixed block 23 to be adjusted when a larger angle rotation is required, and can be adjusted according to actual usage needs.

[0032] Working principle and process: When adjusting the position of the fixed block 23, the operator first rotates the fixed block 23. During the rotation, the handle 25 drives the movable rod 22 to rotate. At this time, the fixed block 23 rotates inside the adjustment groove 21 through the movable rod 22, so that the angle of the fixed block 23 can be adjusted. During the rotation of the fixed block 23, the movable rod 22 rotates in the damping strip 32 in the groove on the surface of the locking strip 31. The damping strip 32 can dampen the movable rod 22, preventing the fixed block 23 from rotating too much, so that the angle of the fixed block 23 can be adjusted more accurately, further improving the use effect of the device. Since the locking strip 31 is made of "metal elastic steel", the operator can pry open the locking strip 31 to deform it, thereby reducing the damping of the movable rod 22. When a larger angle rotation is required, the position of the fixed block 23 can be adjusted according to the actual use needs.

[0033] After the angle of the fixing block 23 is adjusted, the operator inserts the safety pin 26 on the handle plate 25 into the slot opened on the surface of the S-type seven-hole clavicle steel plate body 1, thereby fixing the angle of the fixing block 23 after adjustment, and preventing the fixing block 23 from shifting position during normal use, which would affect the normal use of the S-type seven-hole clavicle steel plate body 1.

[0034] Since the surface of the S-shaped seven-hole clavicle steel plate body 1 has multiple slots, it can be fixed according to the different angles of the fixed block 23, which greatly improves the effect of the device in use.

[0035] After the position of the fixing block 23 is adjusted, the operator will thread the locking screw 24 into the inside of the fixing block 23, and then rotate it through the cross groove of the locking screw 24 so that the locking screw 24 is threaded into the inside of the fracture fragment.

[0036] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
