[0006] Furthermore, the skin contact layer comprises a Chinese medicine extract layer, a biomaterial layer and a temperature control layer, the Chinese medicine extract includes at least two of Rhizoma Polygoni Multiflori, Cinnamomum cassia, and Artemisia argyi; the biomaterial layer is gelatin sponge or chitosan-based hydrogel; and the temperature control layer is composed of quicklime or iron powder-activated carbon reaction system.

[0007] Furthermore, the plate body is made of an arc-shaped titanium alloy plate with a length of 28 mm and a thickness of 2.mm. The middle part bulges upward to form a smooth curved surface, and screw holes with a diameter of 4.mm are evenly distributed on both sides; the middle screw is designed as a bare rod structure with no threads on the upper part to avoid cutting the tendon, and the thread depth of the lower quarter can adjust the fixing strength.

[0008] Furthermore, the surface of the plate body is coated with a synthetic bioceramic coating.

[0009] Furthermore, the adjustable tendon fixing device also includes an auxiliary structure, which includes a claw hand, and the claw hand is equipped with a locking mechanism. The locking mechanism is arranged on a connecting plate, and the connecting plate is connected to the plate body.

[0010] Compared with the prior art, the present invention has the following beneficial effects: the present invention combines a plurality of the plate bodies to form a fixing plate adapted to different patients for fixing, and contacts the patient's skin through the skin contact layer.

[0011] Other advantages, objectives and features of the present invention will be embodied in part through the following description, and in part will be understood by those skilled in the art through study and practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] In order to make the technical means, creative features, objectives and functions of the present invention clearer and easier to understand, the present invention is further described below in conjunction with the accompanying drawings and specific embodiments:

[0016] The present invention proposes an adjustable tendon fixing device, including a plate body 1, on which a plurality of grooves 2 and bosses 4 are provided, wherein the grooves 2 and bosses 4 are respectively located on the front and rear sides of the plate body 1, and a depression 3 with the same structure as the groove 2 is provided on the right side surface of the plate body 1. A plurality of the plate bodies 1 are spliced ​​with the grooves 2 and the depression 3 through the bosses 4 to form a fixing structure 5 for fixing the tendon part, an inflation cavity 6 is provided inside the plate body 1, and a skin contact layer 7 is provided on the skin surface of the fixing structure 5 facing the skin.

[0017] The skin contact layer 7 comprises a Chinese medicine extract layer, a biomaterial layer and a temperature control layer, wherein the Chinese medicine extract includes at least two of Caulis Sophorae Folium, Cinnamomum cassia twig and Artemisia argyi; the biomaterial layer is gelatin sponge or chitosan-based hydrogel; the temperature control layer is composed of quicklime or iron powder-activated carbon reaction system.

[0018] The plate body 1 is made of an arc-shaped titanium alloy plate with a length of 28mm and a thickness of 2.0mm. The middle part bulges upward to form a smooth curved surface, and screw holes with a diameter of 4.0mm are evenly distributed on both sides. The middle screw is designed as a bare rod structure with no threads on the upper part to avoid cutting the tendon, and the thread depth of the lower quarter can adjust the fixing strength.

[0019] The surface of the plate body 1 is coated with a synthetic bioceramic coating citrate-phosphate composite system to promote bone ingrowth and reduce the risk of chronic inflammation.
