Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical appliances, and in particular relates to a fixation plate for bone and joint fractures. Background Art
[0002] When a joint fracture occurs, it will cause local pain, swelling and limited movement. In order to prevent the fracture end from healing as soon as possible and to avoid deformity in the later stage, it is necessary to improve it through splint fixation. Splint fixation is a kind of external fixation treatment, which mainly fixes the affected limb and the splint together to achieve the purpose of fixation. If a fracture occurs, the use of splint fixation can not only play a role in fixation, but also prevent the fracture end from shifting, so as not to affect the healing of the fracture. If the fracture is relatively minor, after the functional position of the joint is fixed by the splint for a period of time, the fracture end will gradually stabilize. However, the flexion and extension angles of the functional positions of the joints are different. For example, the functional position of the wrist joint is a slight dorsiflexion of the wrist joint by about 20 degrees, and the functional position of the elbow joint is a 90-degree bend of the elbow. Therefore, the flexion and extension angles of different joints are different. The existing splints for bone and joint fractures can only be limited to the use of a certain joint, and the angle of flexion and extension of the joint cannot be adjusted. It cannot be applied to multiple joints. Therefore, a fixation plate for bone and joint fractures is proposed. Utility Model Content
[0003] In view of the above problems, the purpose of the present utility model is to provide a fixation plate for bone and joint fractures, which can be adjusted according to the flexion and extension angles of the functional positions after multiple joint fractures, so as to be suitable for fixation after multiple joint fractures.
[0004] To achieve the above purpose, the technical solution adopted by the utility model is: a fixation plate for bone joint fractures, comprising a plate body one and a plate body two, both ends of the plate body one are provided with fixed shafts, the plate body two is rotatably connected to the fixed shaft, plug-in components are provided on both sides of the fixed shaft, the plug-in components include a plug-in disk, a socket, a plug-in rod and a sliding block, there are multiple sockets, and the multiple sockets are equidistantly arranged around the central axis of the plug-in disk, the plug-in rod is adapted to the socket, the sliding block is located on the side of the plug-in rod away from the socket, two sliding grooves are symmetrically opened on the outer side of the plate body two, and the sliding block is slidably connected to the inside of the sliding groove.
[0005] The beneficial effect of the utility model is that the angle between the plate body 1 and the plate body 2 can be adjusted by adjusting the plug-in assembly, so that the fixing plate can be adjusted according to the functional positions of different joints, so that the fixing plate has a wider range of use.
[0006] In order to automatically insert the rod into the socket;
[0007] As a further improvement of the above technical solution: a spring is connected between the inner wall of the sliding groove and the sliding block.
[0008] The beneficial effect of this improvement is that after the angle between the plate body 1 and the plate body 2 is adjusted, the insertion rod is automatically inserted into the insertion hole under the elastic action of the spring.

[0017] The beneficial effect of this improvement is that different joints and limbs have different thicknesses, and the setting of the soft board allows the limbs to fit different limbs when being wrapped.
[0018] To immobilize a limb;
[0019] As a further improvement of the above technical solution: a plurality of the soft boards are provided with straps, and the straps are attached by Velcro.

[0032] In order to enable those skilled in the art to better understand the technical solution of the utility model, the utility model is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the utility model.
[0033] like Figure 1-7As shown, a fixation plate for bone joint fractures includes a plate body 1 and a plate body 2, both ends of the plate body 1 are provided with fixed shafts 3, the plate body 2 is rotatably connected to the fixed shaft 3, both sides of the fixed shaft 3 are provided with plug-in components, the plug-in components include a plug-in plate 4, a plug hole 5, a plug rod 6 and a sliding block 7, the plug holes 5 are multiple, and the multiple plug holes 5 are equidistantly arranged around the central axis of the plug plate 4, the plug rod 6 is adapted to the plug hole 5, the sliding block 7 is located on the side of the plug rod 6 away from the plug hole 5, and the outer side of the plate body 2 is provided with a plug-in assembly. Two sliding grooves 8 are symmetrically provided, and the sliding block 7 is slidably connected to the inside of the sliding groove 8. By adjusting the plug-in assembly, the angle adjustment between the plate body 1 and the plate body 2 is realized, so that it can be adjusted according to the functional position of different joints, so that the fixed plate has a wider range of use; a spring 9 is connected between the inner wall of the sliding groove 8 and the sliding block 7. When the angle between the plate body 1 and the plate body 2 is adjusted, the insertion rod 6 is automatically inserted into the socket 5 under the elastic action of the spring 9; a plurality of the sockets 5 are provided with trumpet-shaped guide parts 1 0, a conical portion 11 is provided on the end of the plug rod 6 away from the sliding block 7. When the plug rod 6 is to be inserted into the insertion hole 5, the plug rod 6 may be inserted between the two insertion holes 5. However, due to the effect of the guide portion 10 and the conical portion 11, when the conical portion 11 hits the guide portion 10, the inclined surfaces of the two are in contact, and the plug rod 6 is automatically slid into the insertion hole 5; a handle 12 is provided on the sliding block 7, and the setting of the handle 12 makes it more convenient for the user to use when adjusting the plug assembly; a plurality of soft boards 13 are symmetrically provided on the plate body 2, wherein the soft board 1 3 can be made of PP, PE and other materials. Different joints and limbs have different thicknesses. The setting of the soft board 13 can fit different limbs when wrapping the limbs; multiple soft boards 13 are provided with straps 14, and the straps 14 are set by Velcro. The straps 14 fix the limbs and make the joint fixation more effective; the plate body 1 and the plate body 2 are both provided with arc-shaped cushions 15, and the arc-shaped cushions 15 can be cotton pads, sponge pads, etc. The arc-shaped cushions 15 increase the comfort of the patient and avoid the discomfort caused by mechanical contact.
[0034] The working principle and use process of the utility model are as follows: when using the device, when a patient has a joint fracture, the angle between the plate body 1 and the plate body 2 is adjusted according to the functional position that needs to be fixed for different fractured joints, so as to adapt to different joints. First, the user moves the two handles 12 relative to each other by hand, so that the handles 12 drive the sliding block 7 to slide in the sliding groove 8 to squeeze the spring 9. At this time, the spring 9 is deformed and drives the insertion rod 6 away from the insertion hole 5. Then, the plate body 2 is rotated to move the plate body 2 to a suitable position, and then the handle 12 is released. At this time, the spring 9 recovers its deformation, and then the sliding block 7 is pushed. The sliding block 7 drives the insertion rod 6 to be inserted into the socket 5. Due to the effect of the guide portion 10 on the socket 5 and the conical portion 11 on the insertion rod 6, the insertion rod 6 can always be inserted into the socket 5, avoiding the situation where the insertion rod 6 is inserted between the two sockets 5 after letting go. Then the injured joint is aligned with the plate body 1, and then the limbs on both sides of the fractured joint are placed on the plate body 2 2. The arc-shaped soft pad 15 protects the patient's limbs to prevent discomfort caused by mechanical contact. Then, the soft board 13 is pressed against the patient's limbs according to the thickness of the limbs, and then the strap 14 is tightened by Velcro. The design is simple, practical and easy to operate.
