[0020] The technical solutions of the present utility model will be described in detail below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Combination Figure 1-4As shown, the universal locking humeral neck type bone plate includes a strip plate body 100. The surface of the strip plate body 100 has multiple universal ring holes 101. A pin hole 102 is formed on one side of the universal ring hole 101. A universal ring 103 is locked inside the universal ring hole 101. The universal ring 103 is C-shaped. A notch 104 is formed on one side of the universal ring 103. The outer diameter of the universal ring 103 is slightly larger than the inner diameter of the universal ring hole 101. Multiple circumferential teeth 105 are formed on the outer side of the universal ring 103. The outer diameter of the middle part of the universal ring 103 is slightly larger than the outer diameters of the upper and lower ends. A universal thread 106 is formed inside the universal ring 103. It also includes a pin 107, which is locked into both the notch 104 and the pin hole 102. The pin hole 102 intersects with the universal joint hole 101. The pin 107 is slightly larger than the pin hole 102, and one side of the pin 107 is engaged with the notch 104. The head of the strip plate 100 has an anatomically curved surface 108 that conforms to the bone, and the tail has a wedge-shaped implant end 109. The length of the strip plate 100 is 245 mm. Shaping grooves 110 are formed on both sides of the strip plate 100 near the middle. Ordinary screw holes 111 are provided on the strip plate 100. Multiple Kirschner wire holes 112 are formed on the strip plate 100. Multiple elongated holes 113 are formed on the strip plate 100.

[0022] In this embodiment, 1. Most humeral plates on the market are neck-type and relatively short. When the humeral neck and humeral shaft are fractured at the same time, they cannot be handled well, and sometimes two plates are needed for fixation. This design is an extended plate type, which can solve the above problems well; 2. The front and back of this product are both arc-shaped, which fits the bone surface better and reduces the feeling of foreign body; 3. The unique universal structure design of this product allows for adjustment of the proximal angle, which is convenient for clinical selection; 4. This product relies on computer-generated digital titanium plates, which perfectly fit the anatomical curvature and are aesthetically pleasing and natural.

[0023] In practical use, select the appropriate size universal joint for different sizes. Because the universal joint has a C-shaped notch, it increases elasticity. When using it, press it inwards to engage with the universal joint hole; this ensures a stable engagement. Since the pin engages with the universal joint hole, part of the pin will enter the hole, preventing the universal joint from rotating within it, thus maintaining its stability and consequently the overall stability. A slightly larger pin size provides even greater stability after being hammered into the hole. The circumferential teeth increase friction, making the connection more stable. The outer diameter of the middle part of the universal joint is slightly larger than the outer diameters of the top and bottom ends, allowing for better hammering and increased friction as the middle engages more effectively. The shaping groove facilitates shaping. Ordinary screw holes, Kirschner wire holes, and elongated holes fulfill their respective functions; the elongated holes facilitate adjustment.

[0024] 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 a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0025] The above description is only a specific embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
