Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a clavicle fixation device. Background Technology

[0002] A clavicle fixation strap is an auxiliary medical device used to treat clavicle fractures. Its main function is to limit the displacement of the fracture ends, prevent damage to adjacent blood vessels and nerves, and ensure the physiological healing of the fracture ends. A search revealed a clavicle fixation strap in patent publication number CN208339646U. This patent addresses the technical problem of existing clavicle fixation straps requiring assistance from others for wearing, which is highly inconvenient.

[0003] However, the aforementioned clavicle fixation straps still require professional guidance during use. The straps should be placed in the correct position, and the elastic bands on both sides should be adjusted to a comfortable level. Most existing clavicle fixation straps are made of soft materials, which can easily shift after prolonged wear. If this happens, without professional guidance, patients may find it difficult to restore the fixation device to its correct position, thus affecting the treatment outcome. Utility Model Content

[0004] The purpose of this invention is to provide a clavicle fixation device made of thermoplastic material, which can fit and fix the clavicle curve of different patients. Even if displacement occurs, the patient can reset it on their own, which helps to improve the treatment effect.

[0005] In a first aspect, this utility model provides a clavicle fixation device, comprising:

[0006] A first thermoplastic part is provided with a first rotating hole, and a first fastening part is provided at each of the opposite ends of the first thermoplastic part;

[0007] The second thermoplastic part is provided with a second rotating hole, and the two opposite ends of the second thermoplastic part are respectively provided with second fastening parts, and the first fastening part can be fastened and fixed with the second fastening part;

[0008] The rotating shaft passes sequentially through the first rotating hole and the second rotating hole;

[0009] A first gasket is disposed on the side of the rotating shaft close to the first thermoplastic part, and the outer diameter of the first gasket is larger than the inner diameter of the first rotating hole;

[0010] The second gasket is disposed on the side of the rotating shaft near the second thermoplastic part. The outer diameter of the second gasket is larger than the inner diameter of the second rotating hole, and the rotating shaft, the first gasket and the second gasket are integrally formed.

[0011] The clavicle fixation device provided by this utility model allows for adjustment of the rotation angle between the first and second thermoplastic parts via a rotating shaft. Before applying the device to the patient's clavicle, the first and second thermoplastic parts are heated in a hot water bath until softened (the water bath temperature can be 60°C). The softened parts are then placed on the patient's clavicle for shaping. After shaping, the parts are fastened using the first and second fastening parts. After cooling and hardening, the first and second thermoplastic parts conform to the patient's bone position, providing good fit and minimizing displacement. Even if displacement occurs, the patient can adjust the first and second thermoplastic parts to the correct position, helping to ensure the treatment effect.

[0012] Furthermore, the inner side of the first thermoplastic part is provided with a first groove, and there are multiple first grooves, which are spaced apart on the first thermoplastic part.

[0013] By adopting the above technical solution and setting multiple first grooves, the first thermoplastic part can be easily shaped, while also improving the heat dissipation capacity of the first thermoplastic part after wearing, thereby enhancing the wearing comfort of the first thermoplastic part.

[0014] Furthermore, the cross-section of the first groove is V-shaped.

[0015] Furthermore, the inner side of the second thermoplastic part is provided with a second groove, and there are multiple second grooves, which are spaced apart on the second thermoplastic part.

[0016] By adopting the above technical solution and setting multiple second grooves, the second thermoplastic part can be easily shaped, and its heat dissipation capacity after being worn can be improved, thereby enhancing the wearing comfort of the second thermoplastic part.

[0017] Furthermore, the cross-section of the second groove is V-shaped.

[0018] Furthermore, both the first thermoplastic part and the second thermoplastic part are light-transmitting thermoplastic parts.

[0019] Using the above technical solution, both the first and second thermoplastic parts are translucent thermoplastic parts, which facilitates medical staff to observe the position of the adhesive fixation.

[0020] Furthermore, the first thermoplastic part is provided with a first vent hole, and there are multiple first vent holes, which are spaced apart on the first thermoplastic part.

[0021] By adopting the above technical solution, by setting multiple first ventilation holes on the first thermoplastic part, the heat dissipation capacity of the first thermoplastic part can be improved, thereby enhancing the wearing comfort of the first thermoplastic part.

[0022] Furthermore, the second thermoplastic part is provided with a second vent hole, and there are multiple second vent holes, which are spaced apart on the second thermoplastic part.

[0023] By adopting the above technical solution, and by setting multiple second ventilation holes on the second thermoplastic part, the heat dissipation capacity of the second thermoplastic part can be improved, thereby enhancing the wearing comfort of the second thermoplastic part.

[0024] Furthermore, the melting points of the materials of the rotating shaft, the first gasket, and the second gasket are greater than the melting points of the first thermoplastic part and the second thermoplastic part.

[0025] As can be seen from the above, the clavicle fixation device provided by this utility model can adjust the rotation angle between the first thermoplastic part and the second thermoplastic part through the rotating shaft. Before applying the device to the patient's clavicle, the first and second thermoplastic parts are first placed in a hot water bath to soften them (the water bath temperature can be 60°C). The softened first and second thermoplastic parts are then placed on the patient's clavicle for shaping. After shaping, they are fastened and fixed by the first and second fastening parts. After the first and second thermoplastic parts cool and harden, they fit the patient's bone position well, have good conformity, and are not prone to displacement. Even if displacement occurs, the patient can adjust the first and second thermoplastic parts to the correct position by themselves, which helps to ensure the treatment effect.

The objectives and other advantages of this application may be realized and obtained by means of the structures particularly pointed out in the written description and the accompanying drawings.
