Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a fracture fixation device. Background Technology
[0002] Traditional Chinese medicine (TCM) is a discipline that studies human physiology, pathology, and the diagnosis and treatment of diseases. In TCM treatment, fixation devices are often used to clamp the fracture site of orthopedic patients, similar to splints and plaster casts in Western medicine. Fixation devices can prevent the fracture site from bending again and can correct the fracture site, helping the bones to grow and recover quickly.
[0003] In the prior art, Chinese patent document with application number 202021533201.5 discloses a fracture fixation device for traditional Chinese medicine bone setting. This utility model is equipped with an arc-shaped mounting plate, a fixing nut, a fixing bolt, and a hinge shaft. The arc-shaped mounting plate is hinged to the outside of the hinge shaft. In use, the arc-shaped mounting plate can be rotated to fit on the outside of the patient's limb. Then, the fixing bolt is screwed into the fixing nut to fix the arc-shaped mounting plate, thereby fixing the device on the outside of the patient's limb.
[0004] However, the above-mentioned technical solutions have limitations in that the fixation distance of the fixation device is singular and cannot be adjusted, making it difficult to achieve orthostatic fixation for patients with limbs of different thicknesses. This reduces the scope of application, has poor applicability, reduces doctors' work efficiency, and fails to meet the needs of use. Therefore, this application proposes a fracture orthostatic fixation device to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing fixation devices, such as limited fixation distance, inability to adjust, difficulty in achieving orthostatic fixation for limbs of different thicknesses, reduced application range, poor applicability, reduced doctor's work efficiency, and inability to meet usage needs. Therefore, this invention proposes an orthostatic fixation device for fractures.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A fracture fixation device includes a base, and the fixation device further includes:
[0008] A top plate, which is disposed above the base;
[0009] The lower clamping plate is fixedly installed on the top of the base;
[0010] The upper clamping plate is located below the top plate and cooperates with the lower clamping plate.
[0011] The mounting assembly includes two vertical rods, two locking rods, and two second springs. The top ends of the two vertical rods are fixedly installed at the bottom of the top plate. The ends of the two locking rods that are close to each other pass through the two vertical rods and are slidably connected to them. The base has slots on the left and right sides. The ends of the two locking rods that are close to each other can be disengaged and inserted into the two slots. The second springs are sleeved on the corresponding locking rods. One end of the second spring is fixedly installed on the corresponding locking rod, and the other end of the second spring is fixedly installed on one side of the corresponding vertical rod.
[0012] A transmission assembly is mounted on the top plate and cooperates with the upper clamping plate;

[0014] A pressure display is fixedly mounted on the front side of the base, and the pressure display is in conjunction with a pressure sensor.
[0015] As a preferred embodiment of this utility model, an anti-slip pad is fixedly adhered to the bottom of the base.
[0016] As a preferred embodiment of this utility model, soft pads are fixedly adhered to the top of the lower clamping plate and the bottom of the upper clamping plate.
[0017] As a preferred embodiment of this utility model, positioning rods are fixedly installed at the four bottom corners of the top plate, and positioning grooves are opened at the four top corners of the base. The bottom ends of the positioning rods can be detached and inserted into the corresponding positioning grooves.
[0018] As a preferred embodiment of this utility model, a first spring is fixedly installed on the bottom inner wall of each of the four positioning grooves, and a sliding plate is fixedly installed on the top of each of the four first springs, with the sliding plate slidably connected to the inner wall of the corresponding positioning groove.
[0019] As a preferred embodiment of this utility model, the transmission assembly includes a dual-axis lead screw, two nuts, two moving rods, and four connecting rods. A rectangular groove is provided at the bottom of the top plate. The left end of the dual-axis lead screw passes through the right side of the top plate and is rotatably connected to the left inner wall of the rectangular groove. Both nuts are threaded onto the dual-axis lead screw. The bottom of the moving rod is fixedly installed on the bottom of the corresponding nut. The top end of the connecting rod is rotatably connected to the corresponding moving rod. The bottom end of the connecting rod is rotatably connected to one side of the upper clamping plate.
[0020] Beneficial effects:
[0021] 1. The two second springs pull the two locking rods closer together, and then the two locking rods can be inserted into the two locking slots. At this time, the insertion limit between the two locking rods and the two locking slots can fix the two vertical rods to the base when the top plate is placed on top of the base, so that the top plate can be installed on the top of the base. Similarly, the upper clamping plate can be installed directly above the lower clamping plate. This method can realize the quick assembly and disassembly of the top plate and the upper clamping plate to the base, which can facilitate the use of the positioning and fixing device by personnel.
[0022] 2. By rotating the dual-axis lead screw and engaging the threaded connection between the lead screw and two nuts, the two moving rods can be driven to move closer together. At this time, the two moving rods can drive the two connecting rods on the left and the two connecting rods on the right to move closer together. When the two connecting rods on the left and the two connecting rods on the right move closer together, the upper clamp can be moved downward. When the upper clamp moves downward, the distance between the upper clamp and the lower clamp can be adjusted, so as to achieve orthostatic fixation of limbs of different thicknesses, improve the scope of application, improve the efficiency of doctors' work, and meet the needs of use.
[0023] This utility model achieves adjustable spacing between the upper and lower splints through a simple structure, enabling orthopedic fixation of limbs of patients with different thicknesses, thus expanding its applicability. At the same time, it facilitates the assembly and disassembly of the upper splint, making it convenient for personnel to fix the patient's limbs. It is convenient, quick, and highly practical.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0032] Example
[0033] Reference Figures 1-6 A fracture fixation device, including a base 1, further comprising:
[0034] Top plate 3, which is positioned above base 1;
[0035] The lower clamping plate 12 is fixedly installed on the top of the base 1;
[0036] Upper clamping plate 13 is located below the top plate 3 and cooperates with lower clamping plate 12;
[0037] The mounting assembly includes two vertical rods 9, two locking rods 10, and two second springs 11. The top ends of the two vertical rods 9 are fixedly installed at the bottom of the top plate 3. The ends of the two locking rods 10 that are close to each other pass through the two vertical rods 9 and are slidably connected to the vertical rods 9. The left and right sides of the base 1 are provided with locking slots 8. The ends of the two locking rods 10 that are close to each other can be disengaged and inserted into the two locking slots 8. The second springs 11 are sleeved on the corresponding locking rods 10. One end of the second springs 11 is fixedly installed on the corresponding locking rods 10, and the other end of the second springs 11 is fixedly installed on one side of the corresponding vertical rod 9.
[0038] The transmission assembly is mounted on the top plate 3 and cooperates with the upper clamping plate 13.
[0039] Pressure sensor 20 is fixedly installed on the top of base 1 and cooperates with lower clamping plate 12;
[0040] Pressure display 21 is fixedly installed on the front side of base 1 and cooperates with pressure sensor 20.
[0041] With the above structure, the two second springs 11 cause the two locking rods 10 to move closer to each other, and then the two locking rods 10 can be inserted into the two locking slots 8. At this time, the insertion limit between the two locking rods 10 and the two locking slots 8 allows the two vertical rods 9 to be installed and fixed between the top plate 3 and the base 1 when the top plate 3 is placed on top of the base 1, so that the top plate 3 can be installed above the base 1. Similarly, the upper clamping plate 13 can be installed directly above the lower clamping plate 12. In this way, the top plate 3 and the upper clamping plate 13 can be quickly disassembled and assembled with the base 1, which makes it convenient for personnel to use the positioning and fixing device.
[0042] As a preferred embodiment of this utility model, an anti-slip pad 2 is fixedly bonded to the bottom of the base 1. By setting the anti-slip pad 2, the entire device can be anti-slip supported, thereby improving the stability of the positioning and fixing device.
[0043] As a preferred embodiment of this utility model, soft pads 14 are fixedly adhered to the top of the lower splint 12 and the bottom of the upper splint 13. By setting the soft pads 14, the clamping protection of the patient's limb by the upper splint 12 and the lower splint 13 can be improved.
[0044] As a preferred embodiment of this utility model, positioning rods 4 are fixedly installed at the four bottom corners of the top plate 3, and positioning grooves 5 are opened at the four top corners of the base 1. The bottom end of the positioning rod 4 can be disengaged and inserted into the corresponding positioning groove 5. By limiting the insertion between the positioning rod 4 and the positioning groove 5, the stability of the top plate 3 and the base 1 after installation can be improved.
[0045] As a preferred embodiment of this utility model, a first spring 6 is fixedly installed on the bottom inner wall of each of the four positioning grooves 5, and a sliding plate 7 is fixedly installed on the top of each of the four first springs 6. The sliding plate 7 is slidably connected to the inner wall of the corresponding positioning groove 5. The sliding plate 7 is driven to move up and down by the elastic force of the first spring 6, which makes it easy to push the positioning rod 4 out of the positioning groove 5 when disassembling the top plate 3, making it convenient for personnel to disassemble the top plate 3.
[0046] In a preferred embodiment of this utility model, the transmission assembly includes a dual-axis lead screw 16, two nuts 17, two moving rods 18, and four connecting rods 19. A rectangular groove 15 is formed at the bottom of the top plate 3. The left end of the dual-axis lead screw 16 passes through the right side of the top plate 3 and is rotatably connected to the left inner wall of the rectangular groove 15. Both nuts 17 are threaded onto the dual-axis lead screw 16. The bottom of each moving rod 18 is fixedly installed at the bottom of its corresponding nut 17. The top end of each connecting rod 19 is rotatably connected to its corresponding moving rod 18, and the bottom end of each connecting rod 19 is rotatably connected to one side of the upper clamping plate 13. By rotating the dual-axis lead screw 16... 6. Through the threaded connection between the dual-axis lead screw 16 and the two nuts 17, the two moving rods 18 can be driven to move closer to each other. At this time, the two moving rods 18 can drive the two connecting rods 19 on the left and the two connecting rods 19 on the right to move closer to each other. When the two connecting rods 19 and the two connecting rods 19 on the right move closer to each other, the upper clamp 13 can be driven to move downward. When the upper clamp 13 moves downward, the distance between the upper clamp 13 and the lower clamp 12 can be adjusted, so as to realize the orthostatic fixation of patients' limbs of different thicknesses, improve the scope of application, improve the efficiency of doctors' work, and meet the needs of use.
[0047] The working principle of this utility model is as follows: In use, first, place the patient's limb requiring proper positioning on the lower splint 12. Then, place the top plate 3 above the base 1 from top to bottom. At this time, pull the two locking rods 10 to the side furthest from each other, simultaneously engaging the positioning rod 4 with the positioning groove 5. Then, when the locking rods 10 correspond to the grooves 8, release the two locking rods 10. The elastic force of the second spring 11 causes the two locking rods 10 to move closer together and complete the engagement and positioning between the two grooves 8. At this point, the installation of the top plate 3 and the base 1 is complete, and the upper splint 13 is directly above the patient's limb and the lower splint 12. Then, by rotating the double-axis lead screw 16 and engaging the threaded connection between the double-axis lead screw 16 and the two nuts 17 (one side of the double-axis lead screw 16 is a right-hand thread, and the other side is a left-hand thread, with opposite thread directions), the two moving rods 18 can be moved closer together. At this point, the two moving rods 18 can drive the two connecting rods 19 on the left and the two connecting rods 19 on the right to move closer together. When the two connecting rods 19 and the two connecting rods 19 on the right move closer together, the upper clamp 13 can be moved downward. When the upper clamp 13 moves downward, the distance between the upper clamp 13 and the lower clamp 12 can be adjusted, so as to fix the limbs of patients of different thicknesses in an orthopedic position, improve the scope of application, improve the efficiency of doctors' work, and meet the needs of use. At the same time, the pressure sensor 20 can detect the clamping force between the upper clamp 13 and the lower clamp 12, and the pressure display 21 can display the value of the clamping force, so as to control the appropriate force when the person rotates the dual-axis lead screw 16, avoid the upper clamp 13 and the lower clamp 12 from applying too much pressure to the person's limb, and achieve stable fixation while ensuring clamping force, which is highly practical.
[0048] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
