[0002] In orthopedic clinical practice, patients with fractures are frequently admitted. When a patient has a humeral fracture, a proximal humeral locking plate is often used for treatment. A humeral locking plate is a surgical instrument used to treat humeral fractures. It is usually made of metal and includes a screw and a locking plate to fix the fracture site and promote fracture healing. Humeral locking plates are suitable for treating humeral fractures, especially articular surface fractures requiring stabilization or instability.

[0003] As shown in the prior art published in CN215273238U, although this technical solution fixes the bone plate to the patient's bone by screwing the bone screw into the second threaded hole, and when reinforcement is needed, the slider is inserted into the groove from the bottom of the groove, which moves the connecting plate, pressure plate and first reinforcement plate to the position to be reinforced, and then the slider is pressed into the corresponding second slot, the connecting plate presses the pressure plate into the first slot, and then the first reinforcement screw is screwed into the first reinforcement plate to reinforce from the side of the bone. However, the bone plate in this technical solution has a fixed length, which means that the length of this technical solution cannot be adjusted according to the needs of bone setting, thus making this technical solution have certain limitations. Utility Model Content

[0024] 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.

[0025] Refer to the instruction manual appendix Figure 1-5 This utility model provides a humeral bone setting locking plate, including a locking plate body for humeral bone setting; the locking plate body includes a main plate 4, a support plate 5, and a fixing plate 6, the support plate 5 is disposed between the main plate 4 and the fixing plate 6, and the main plate 4 is disposed on the side of the fixing plate 6 near the connecting plate 1; a locking hole 7 is opened on the side of the main plate 4 near the connecting plate 1, and an assembly plate 2 on the connecting plate 1 located on the side of the main plate 4 extends into the locking hole 7. Through the assembly of the main plate 4, the support plate 5, and the fixing plate 6, medical personnel can easily perform bone setting on the patient's humerus. Both the main board 4 and the connecting plate 1 have first locking holes 10 on their exteriors, and the fixing plate 6 has multiple spaced second locking holes 11 on its exterior. This allows the locking plate body to be installed onto the patient's humeral bone graft site via the first locking holes 10. Furthermore, since the main board 4, the connecting plate 1, and the fixing plate 6 all have multiple spaced reinforcing holes 14 on their exteriors, medical personnel can install bone graft bolts via the reinforcing holes 14. This enhances the stability of the locking plate body and prevents it from becoming loose and falling to the ground.

[0026] like Figure 1 , 4 As shown in Figure 5, the outer side of the locking plate body is provided with multiple sets of auxiliary components for increasing the bone length; each set of auxiliary components includes a connecting plate 1 located on one side of the locking plate body, an assembly plate 2 is provided on the side of the connecting plate 1 close to the locking plate body, and an assembly hole 3 is provided on the side of the connecting plate 1 away from the locking plate body.

[0027] The first locking hole 10 and the second locking hole 11 on the main body of the locking plate facilitate the operation of bone screws by medical staff to install and fix the locking plate. At the same time, in order to improve the operability of the main body of the locking plate and facilitate the length adjustment according to the bone setting needs, medical staff insert the assembly plate 2 on the connecting plate 1 into the card hole 7 on the main plate 4 and assemble and fix it by fastening bolt 13. Then, the remaining connecting plates 1 are assembled and connected by the assembly hole 3. This facilitates the length adjustment according to the bone setting needs, thereby improving the practicality and operability of this utility model.

[0028] To ensure the stability of the connecting plate 1 during installation, such as Figure 3-5 As shown, two spaced positioning strips 8 are installed at the top and bottom of the inner cavity of the card hole 7 and at the top and bottom of the inner cavity of the assembly hole 3. Two spaced positioning holes 9 are opened at the top and bottom of the assembly plate 2. The positioning strips 8 are located inside the positioning holes 9. By engaging with the positioning holes 9, the positioning strips 8 can limit and fix the assembly plate 2, ensuring the stability of the assembly plate 2 and preventing the assembly plate 2 from tilting or shaking. This improves the firmness and stability of the connecting plate 1.

[0029] To enhance the connection stability of connector plate 1, such as Figure 3-5 As shown, mounting holes 12 are provided at the top of the main board 4 near the connecting plate 1 and at the top of the connecting plate 1 away from the main board 4. Fastening bolts 13 are provided inside the mounting holes 12 on the main board 4. The bottom end of the fastening bolts 13 penetrates the mounting plate 2 and extends into the interior of the main board 4. The fastening bolts 13 are threadedly connected to the main board 4. The mounting plate 2 is fixed by the fastening bolts 13, which can enhance the installation stability of the mounting plate 2, prevent the mounting plate 2 from loosening, and enhance the tightness and stability of the connection between the connecting plate 1 and the locking plate body.
