Description

Technical Field

[0001] This utility model relates to the field of bone plate technology, specifically a novel bone plate for treating nonunion of the humeral shaft. Background Technology

[0002] The humerus is the strongest bone in the upper limb. Its upper end forms the shoulder joint with the scapula, and its lower end forms the elbow joint with the radius and ulna. A humeral shaft fracture refers to a discontinuity, breakage, or complete fracture of the humerus shaft in the upper arm due to external force. Severe fractures can lead to displacement and other complications. Clinically, humeral shaft nonunion is usually treated by using a bone plate to connect the broken humeral shaft. During the application of the bone plate, to increase the stability of the connection between the plate and the humeral shaft, the surgeon will insert screws diagonally upwards into the humeral shaft for support and locking, providing more stable support to the medial side of the humeral head.

[0003] However, the screw holes in existing bone plates are fixed, and the angle of the screw holes cannot be adjusted. Consequently, the oblique holes of the bone plate cannot be adjusted according to the patient's age and body type, and doctors cannot choose the appropriate position to tilt and insert the screws. Therefore, it does not meet the current needs. To address this, we propose a new type of bone plate for the treatment of humeral shaft nonunion. Utility Model Content

[0004] The purpose of this invention is to provide a novel bone plate for treating nonunion of the humeral shaft, in order to solve the problem mentioned in the background art that the screw holes of the bone plate are fixed and the angle of the screw holes cannot be adjusted, thus preventing the oblique holes of the bone plate from being adjusted according to the patient's age and body type, and making it impossible for doctors to choose the appropriate position to tilt and insert the screws.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel bone plate for treating nonunion of the humeral shaft, comprising a bone plate body:

[0006] An internal connecting rotating component is installed inside the bone plate body. The bone plate body and the internal connecting rotating component are rotatably connected through a slot. One side of the internal connecting rotating component is set as an inclined structure. An angle adjusting component is installed on one side of the internal connecting rotating component. The side of the angle adjusting component near the internal connecting rotating component is set as an inclined structure. A connecting boss is installed on the side of the angle adjusting component near the internal connecting rotating component. The connecting boss and the internal connecting rotating component are rotatably connected through a slot.

[0007] The first set screw is disposed on one side of the bone plate body and is connected to the bone plate body by threads. The second set screw is installed on one side of the angle adjustment member by threads.

[0008] Preferably, the angle adjusting member has a connecting screw installed inside.

[0009] Preferably, the lower end of the first set screw contacts the internal connecting rotating component when it is tightened.

[0010] Preferably, the lower end of the second set screw contacts the internal connecting rotating part when it is tightened.

[0011] Preferably, the connecting boss and the angle adjustment component are integrally formed.

[0012] Preferably, the end of the internal connecting rotating component that is away from the angle adjusting component is set in a conical shape.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, by installing an internal connecting rotating component and utilizing its inclined surface in conjunction with an angle adjusting component also equipped with an inclined surface, allows doctors to install connecting screws at an angle simply by rotating the angle adjusting component and the internal connecting rotating component. The angle adjusting component rotates around the axis (i.e., the rotation axis) of the connecting boss, while simultaneously rotating the internal connecting rotating component. This causes a spatial change in the position of the inclined surface of the internal connecting rotating component, thereby adjusting the angle of the inclined surface angle adjusting component. This, to a certain extent, can change the installation angle of the connecting screw, allowing the angle of the connecting screw in the device to be adjusted. Consequently, the device can be specifically adjusted according to the patient's age and body type, making it easier for doctors to select the appropriate angle and tilt to insert the connecting screw at the appropriate position.

[0015] 2. This utility model can limit the internal rotating parts by installing the first set screw and limit the angle adjustment parts by installing the second set screw, thereby preventing the device from loosening and enhancing the functional stability of the device.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Please see Figure 1-8 One embodiment of this utility model is a novel bone plate for treating nonunion of the humeral shaft, comprising a bone plate body 1:

[0027] The internal connecting rotating component 3 is installed inside the bone plate body 1. The bone plate body 1 and the internal connecting rotating component 3 are rotatably connected via a slot. The internal connecting rotating component 3, with its inclined surface and an angle adjustment component 4, allows the surgeon to adjust the angle of the connecting screw 2 when an angled installation is required. This is achieved by rotating both the angle adjustment component 4 and the internal connecting rotating component 3, causing the angle adjustment component 4 to rotate around the axis (i.e., the rotation axis) of the connecting boss 5. Simultaneously, rotating the internal connecting rotating component 3 changes the position of its inclined surface, thus adjusting the angle of the angle adjustment component 4. This, to a certain extent, changes the installation angle of the connecting screw 2. This allows the connecting screw 2 of the device to be angled, thereby enabling the device to be adjusted according to the patient's age and body type. This makes it easier for doctors to select the appropriate angle and tilt the screw 2 at the appropriate position. One side of the internal connecting rotating part 3 is set as a slope structure. An angle adjusting part 4 is installed on one side of the internal connecting rotating part 3. The side of the angle adjusting part 4 near the internal connecting rotating part 3 is set as a slope structure. A connecting boss 5 is installed on the side of the angle adjusting part 4 near the internal connecting rotating part 3. The connecting boss 5 is rotatably connected to the internal connecting rotating part 3 through a slot. There are six sets of internal connecting rotating part 3, angle adjusting part 4 and connecting boss.

[0028] The first set screw 6 is located on one side of the bone plate body 1. The first set screw 6 is connected to the bone plate body 1 by a thread. The second set screw 7 is installed on one side of the angle adjustment component 4 by a thread. Installing the first set screw 6 can limit the internal connecting rotating component 3, and installing the second set screw 7 can limit the angle adjustment component 4, thereby preventing the device from loosening and enhancing the functional stability of the device.

[0029] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 The angle adjusting component 4 has a connecting screw 2 installed inside. When the first set screw 6 is tightened, its lower end contacts the internal connecting rotating component 3. When the second set screw 7 is tightened, its lower end contacts the internal connecting rotating component 3. The connecting boss 5 and the angle adjusting component 4 are integrally formed. The end of the internal connecting rotating component 3 away from the angle adjusting component 4 is set into a cone shape. Setting the internal connecting rotating component 3 into a cone shape can facilitate the rotation of the connecting screw 2 and ensure the integrity of the device's functionality.

[0030] Working principle: During use, the doctor selectively rotates the internal connecting rotating part 3 and the angle adjusting part 4 according to the user's body shape. The angle adjusting part 4 rotates around the rotation axis of the connecting boss 5, thereby changing the installation angle of the internal connecting screw 2. After selecting a suitable installation angle, the doctor uses the first set screw 6 and the second set screw 7 to limit the movement of the internal connecting rotating part 3 and the angle adjusting part 4. Finally, the doctor uses a tool to drill a beveled hole in the upper end of the user's humerus and installs the device through part 2 in the upper end of the user's humerus. The device's internal connecting rotating part 3, with its beveled surface, works in conjunction with the angle adjusting part 4, which also has a beveled surface. This allows the doctor to easily install the connecting screw 2 at an angle by simply rotating the angle adjusting part 4 and... The internal connecting rotating component 3 causes the angle adjusting component 4 to rotate around the axis (i.e., the rotation axis) of the connecting boss 5. Simultaneously, rotating the internal connecting rotating component 3 changes the spatial position of the inclined surface, thereby adjusting the angle of the inclined surface angle adjusting component 4. This, in turn, can change the installation angle of the connecting screw 2 to a certain extent, allowing the connecting screw 2 of the device to be angled. This enables the device to be adjusted according to the patient's age and body type, facilitating the doctor to select the appropriate position and angle to tilt and drive the connecting screw 2. Installing the first set screw 6 can limit the internal connecting rotating component 3, and installing the second set screw 7 can limit the angle adjusting component 4, thereby preventing the device from loosening and enhancing the functional stability of the device.
